Anker Nano A1653
30.65€ (14891)
A pocket 5000 mAh power bank that plugs straight into the phone thanks to its built-in foldable USB-C connector, 22.5 W and barely 100 g.
- Capacity: 5000 mAh
- Power: 22.5 W max (USB-C)
- Connectivity: Built-in USB-C plug + USB-C port
- Weight: 100 g
- Built-in USB-C plug, 22.5 W and 100 g, plugs into the phone
The Anker Nano (reference A1653) is a mini power bank of 5000 mAh built for on-the-go top-ups. Its foldable USB-C connector flips out and plugs directly into the phone, with no cable, while an extra USB-C port lets you charge a second device or recharge the battery itself. It delivers up to 22.5 W, enough to quickly give a smartphone a good charge. At 100 g in an ultra-compact cube shape, it slips into any pocket, with four charge LEDs and a shell largely made from recycled plastics.
We took to this Anker Nano A1653 for one simple reason: it fits in a pocket and plugs straight into the phone, with no cable to carry. The foldable USB-C connector is genuinely clever, you flip it out, clip it onto an iPhone or Android phone, and charging starts. At 100 g on the scale, you forget it in a jacket pocket, and the 5000 mAh are enough to give most phones a full charge, plenty to see out a day with peace of mind. The 22.5 W do the job: twenty minutes plugged in and you get a good chunk of battery back. The extra USB-C port is handy for charging a second device or for recharging the battery itself. The matte finish is understated and pleasant, and the four LEDs clearly show the remaining level. Two honest reservations: 5000 mAh is a single recharge, no more, and the little cube shape sticks out a bit when the plug is attached to the phone. But for an ultra-light, always-ready, cable-free top-up, the Nano A1653 is an excellent everyday companion.
Xiaomi Mi Power Bank 3
19.99€ (197)
10000mAh and 22.5W fast charging in an ultra-compact body under 20 euros: the Xiaomi Mi Power Bank 3 is the best-value top-up power bank.
- Capacity: 10000mAh
- Power: 22.5W max (fast charging)
- Ports: 2 USB-A + 1 USB-C (bidirectional)
- Design: Ultra-compact, about 200 g
- 22.5W and 3 ports in a mini body, at a low price
The Xiaomi Mi Power Bank 3 (Ultra Compact) is a 10000mAh power bank in a small body, designed for everyday top-ups. It delivers up to 22.5W fast charging and has 3 ports (2 USB-A and 1 bidirectional USB-C), enough to charge two devices at once. Its USB-C port also recharges it. Compact, sturdy with a tidy finish and offered at a low price, it charges a smartphone about twice. One of the most popular power banks on the market.
The Xiaomi Mi Power Bank 3 is a bit of the default power bank, the one you recommend without a second thought for everyday use. Under 20 euros, it offers 10000mAh in a pocketable body, and its 22.5W fast charging tops up a smartphone far faster than old entry-level banks. We like its 3 ports, which let you plug in two devices at once, and the bidirectional USB-C port that also recharges it. The body is well finished for the price. In real use, it fills a smartphone about twice, enough for a weekend. The downsides are minor: no precise display, and power suited to phones and small devices, not laptops. But for reliable, affordable top-ups, it is hard to do better.
Nitecore NB10000
67.77€ (168)
Ultralight (150 g) and clad in carbon fibre, the Nitecore NB10000 offers 10,000 mAh that shrug off water and knocks, ideal for hiking.
- Capacity: 10,000 mAh
- Power: USB-C 20 W, USB-A 18 W
- Weight: 150 g
- Durability: Carbon fibre, IPX-5, 1.5 m drop
- 150 g carbon fibre, rugged, water-resistant and flight-ready
At just 150 g for 10,000 mAh, the Nitecore NB10000 is one of the lightest power banks on the market. Its carbon fibre body makes it ultra-rugged (1.5 m drop, IPX-5 water resistance) without adding weight. It offers a USB-C 20 W port and a USB-A 18 W port usable at the same time, plus a low-power mode for small devices. Ultra-thin (10.6 mm) and flight-ready, it is built for hiking, trail running, bikepacking and light travel.
We took the Nitecore NB10000 hiking and travelling, and its knockout argument is the weight: 150 g, you literally forget it in the bag. For anyone counting grams on a trek or bikepacking trip, it is a real game-changer, especially as the 10,000 mAh capacity is plenty to last several days with a phone. The carbon fibre body inspires confidence: after a few knocks and a downpour, it looks brand new, and the woven finish is gorgeous. When charging, the 20 W over USB-C top up a smartphone at a good pace, and being able to plug in two devices at once is handy. The low-power mode is clever for charging a watch or earbuds without the battery cutting out. Two honest reservations: the power stays moderate (not enough to charge a big laptop at full speed), and the ultra-thin format, very pleasant, makes it a little slippery. But for a light, tough, reliable outdoor power bank, the NB10000 remains a hard-to-beat benchmark.
Zendure SuperMini 10000mAh
10000mAh in your pocket: the Zendure SuperMini is the size of a credit card yet offers 18W USB-C PD fast charging. One of the most compact power banks on the market.
- Capacity: 10000mAh
- Fast charge: 18W (USB-C PD + USB-A)
- Cells: High-density 21700
- Format: Credit-card size
- 10000mAh ultra-compact with 18W fast charging
The Zendure SuperMini is a remarkably compact 10000mAh power bank, barely larger than a credit card. It delivers 18W fast charging via its USB-C PD and USB-A ports, able to charge an iPhone to 50% in 30 minutes. It uses high-density 21700 cells, 50% denser than conventional cells, which explains its slimness. Its X-Charge mode also charges low-power devices (smartwatches, earbuds). Ideal for daily and travel use thanks to its ultra-portable format.
The Zendure SuperMini made a name for itself by proving you could fit 10000mAh in a case barely bigger than a credit card. In use, that is exactly where its appeal lies: it slips into a jeans pocket or a small pouch without you feeling it, unlike the usual bulky bricks. Its 18W USB-C PD fast charging is enough to charge a smartphone to 50% in half an hour, and the USB-A port powers a second device. We also like the X-Charge mode, designed for small devices like smartwatches or earbuds, which many power banks fail to charge (auto cut-off). Its fluted metal finish is neat and gives a quality feel. The limits come from its format: 18W stays modest against recent power banks climbing to 30W or more, and 10000mAh is enough for about two phone charges, no more. But for a truly portable backup battery, the SuperMini remains a benchmark for compactness.
II - High capacity power banks
Need a lot of power? Here is our selection of the best high capacity external batteries. Heavier and less transportable than other power banks, they are destined for more restricted mobility, but are monsters in terms of capacity.
Anker 737 Power Bank
£139.00 (17068)
24000mAh and 140W of power: the Anker 737 charges a laptop like a smartphone, with a display that shows everything in real time.
- Capacity: 24000mAh (86.4Wh)
- Power: 140W max (Power Delivery 3.1)
- Ports: 2 USB-C + 1 USB-A
- Display: Digital display (power, runtime, time)
- 140W to charge a laptop
The Anker 737 (PowerCore 24K) is a high-capacity 24000mAh power bank able to deliver up to 140W via Power Delivery 3.1. With its 3 ports (2 USB-C and 1 USB-A), it charges a laptop, a smartphone or a tablet at full speed, and can power several devices at once. Its digital display shows input and output power, remaining charge and estimated charging time. It recharges itself at 140W, a full charge in about 1 hour.
The Anker 737 is the power bank you take when you refuse to compromise. Its 140W make it one of the few power banks able to charge a laptop at full speed, MacBook Pro included, and not just as a stopgap. Over a day on the move, it charged a laptop, two smartphones and earbuds without flinching, its 24000mAh offering a real reserve. The digital display is a genuine plus day to day: you see at a glance the power delivered and the remaining runtime, which avoids nasty surprises. It recharges itself very fast, in about an hour with a good 140W charger. The only downsides are its weight and size, hefty for a power bank (over 600 g), and its price, above average. But for real portable power, it is a benchmark.
Anker A1695 (165W)
99.99€ 93.62€
(10130)
With 25,000 mAh, 165 W, two built-in cables and a display, the Anker A1695 power bank even charges a laptop and up to 4 devices at once.
- Capacity: 25,000 mAh (90 Wh)
- Power: 165 W (USB-C 100 W max)
- Ports: 3 USB-C + USB-A + 2 built-in cables
- Weight: 595 g
- 165 W, built-in and retractable cables, display, 4 devices
The Anker A1695 is a 25,000 mAh, 165 W power bank able to charge a laptop as well as a smartphone. Its three USB-C ports (100 W max each) and USB-A port power up to four devices at once, while its two built-in USB-C cables (fixed and retractable) mean no separate cable to carry. A smart display shows charge, power and remaining time. Recharged to 30% in 20 minutes, with 90 Wh cleared for flights, it targets heavy users and mobile work.
The Anker A1695 blew us away with its versatility. It is the first power bank you grab without a second thought: it charges the phone, the tablet and above all the laptop, all at once. The 100 W per USB-C port make a real difference, a MacBook gets half its charge back in half an hour, just like on the mains. But the detail we love is the two built-in cables: the retractable one for daily use, the fixed one as a backup, you never hunt for a cable again. The display is very readable and gives all the useful info, watts in, watts out, time remaining, you always know where you stand. Its 25,000 mAh easily last a big day of work away from an outlet, and it recharges itself quickly. Two honest reservations: at nearly 600 g, this is not a battery you slip into a pocket, it is made for a bag, and its price is higher than a regular power bank. But for intensive use, with this power and these built-in cables, it is hard to fault.
Ugreen Nexode 145W
82.17€ 59.99€
(7052)
The power bank that also charges your laptop: 25000mAh, 145W over USB-C, a control display and enough to power 3 devices at once.
- Capacity: 25,000 mAh (92.5 Wh)
- Power: 145W, USB-C 140W (PD 3.1)
- Ports: 2 USB-C + 1 USB-A
- Weight: 505 g, digital display
- Charges a laptop over USB-C at 140W
The Ugreen Nexode 145W is a high-capacity 25,000 mAh power bank built for demanding travellers: it charges a smartphone and a laptop alike thanks to its USB-C port delivering up to 140W over Power Delivery 3.1. With 145W of total power across 3 ports (2 USB-C and 1 USB-A), it powers a MacBook, an iPhone and earbuds at the same time. Its digital display shows the remaining level and power in real time. Compact for its capacity (505 g) and under the 100 Wh mark, it is allowed in the aircraft cabin.
We took the Ugreen Nexode 145W on a work trip, and it is exactly the kind of battery that puts your mind at ease: head out for a full day with a MacBook, an iPhone and earbuds, and only one accessory to drop in the bag. Plugged in over USB-C, the MacBook Pro charges before your eyes, you get back more than half the battery in half an hour, and meanwhile the iPhone charges on the second port without anything faltering. The display is a real plus day to day: one glance shows the power going out and the percentage left, no more guessing what is in reserve. Recharging the battery itself is quick if you have a strong charger to hand: about two hours with a 65W brick, versus an eternity on a small phone charger. Two honest caveats: it is heavy at 505 g, you will not forget it at the bottom of a pocket, and you have to supply your own powerful charger to enjoy fast recharging (the base version is the battery only). But for anyone after a single battery that can charge a laptop as well as a phone, with headroom to spare, it is a real value-for-money success.
Ugreen Nexode 100W
79.99€ 49.99€
(5228)
Charge a laptop anywhere: 20000mAh, 100W over USB-C, 3 ports and a control display, in a compact 420 g package.
- Capacity: 20,000 mAh (74 Wh)
- Power: 100W, USB-C 100W (PD 3.0)
- Ports: 2 USB-C + 1 USB-A
- Weight: 420 g, LED display
- Charges a laptop over USB-C at 100W
The Ugreen Nexode 100W is a 20,000 mAh power bank built to charge a laptop on the move without weighing you down. Its USB-C port delivers up to 100W over Power Delivery 3.0, enough to power a MacBook or a Windows ultrabook at a good pace. With 3 ports (2 USB-C and 1 USB-A), it charges three devices at once, and its LED display shows the remaining level in real time. Compact and light (420 g) for its capacity, and under the 100 Wh mark, it is allowed in the aircraft cabin: the ideal everyday travel companion.
We used the Ugreen Nexode 100W as our main battery for nomadic remote work, and it quickly became second nature: it charges the MacBook as happily as the phone, and at 420 g it disappears into the bag, which is not the case for every battery able to put out 100W. Over USB-C, an ultrabook gets a solid charge during a coffee break, and the display lets you track exactly the power going out and the percentage left, real peace of mind. The three ports earn their keep every day: you plug in the laptop, the phone and the earbuds without a second thought. We also like that it recharges quickly, in about two hours with a good charger. Two honest caveats: for a big power-hungry laptop, 100W is enough but you can feel the Nexode 145W goes faster, and as so often no wall charger is included, so you need a powerful brick to hand to recharge it quickly. But at the price it is offered, for a 20,000 mAh battery that charges a laptop, with a display and a light format, the value is hard to beat.
Ugreen Nexode Pro 200W
129.99€ 89.99€
(2801)
The most powerful power bank: 25000mAh, 200W to charge two laptops at once, 2 built-in USB-C cables and a colour TFT display.
- Capacity: 25,000 mAh (92.5 Wh)
- Power: 200W, USB-C 140W (PD 3.1)
- Outputs: 4-in-1, 2 built-in USB-C cables
- Weight: 609 g, TFT colour display
- 200W: charges 2 laptops at once
The Ugreen Nexode Pro 200W is the flagship of the range: a 25,000 mAh power bank that delivers up to 200W, enough to charge two laptops at the same time. Its 4-in-1 design builds in two USB-C cables, always ready, plus ports to power up to four devices at once. A colour TFT display shows power and remaining runtime in real time. Under 100 Wh, it is allowed in the aircraft cabin: the ideal tool for nomadic creatives and professionals.
We took the Ugreen Nexode Pro 200W on a multi-day shoot, and it is the kind of battery that wins everyone over: it charges two laptops at the same time, which is rare, and the two built-in cables spare you the scramble for the right cable mid-rush. The colour TFT display is a real plus, you see at a glance the power going out on each output and the time left, no more flying blind. Over USB-C, a MacBook Pro gets back more than half its battery in half an hour, and meanwhile a second laptop and a phone charge without anything faltering. It recharges itself very quickly, welcome when the days pile up. The flip side is the weight: 609 g and a brick-like format you feel in the bag, logical for 25,000 mAh and 200W, but not the battery you slip into a pocket. And as so often, no wall charger is included. But for anyone who needs real power and endurance, with two cables always to hand and an ultra-readable display, the Nexode Pro 200W is a formidable work tool at unbeatable value.
INIU Power Bank 20000mAh
£39.99 (2318)
20000mAh and 65W fast charging in a surprisingly compact body: the INIU power bank even charges a laptop, at an unbeatable price.
- Capacity: 20000mAh
- Power: 65W USB-C (input and output)
- Ports: 3 ports (USB-C + USB-A)
- Extra: Display, compact body, 3-year warranty
- 65W to charge a laptop, at a low price
The INIU 20000mAh 65W power bank is a high-capacity power bank with formidable value. Its USB-C port delivers up to 65W input and output, enough to charge a light laptop (MacBook Air, Steam Deck) at full speed, on top of smartphones and tablets. With its 3 ports, it powers several devices at once, and a display shows the remaining percentage. Surprisingly compact for 20000mAh, it recharges itself in about 2 hours and comes with a 3-year warranty.
The INIU 20000mAh 65W is proof that you can have an excellent power bank without blowing the budget. On paper, its 65W make it a bank able to charge a laptop, and in use it holds up: a MacBook Air and a Steam Deck charged at good speed, on top of the usual phones. What surprises most is its size: for 20000mAh, it stays compact and slips easily into a bag. The display showing the remaining percentage is a real comfort, and the 3-year warranty, rare at this price, is reassuring. It recharges itself in about two hours. The downsides are minor: it caps at 65W where some rivals reach 100W, and the brand is less known than the big names. But for the price, it is simply one of the best deals on the market.
Baseus Bipow Pro 20000mAh
24.99€ (1188)
20000mAh, 25W fast charging and a display for under 30 euros: the Baseus Bipow Pro is the large power bank with unbeatable value.
- Capacity: 20000mAh
- Power: 25W max (Power Delivery)
- Ports: 2 USB-A + 1 USB-C (bidirectional)
- Extra: Percentage display
- 20000mAh, 25W and a display, at a low price
The Baseus Bipow Pro 20000mAh is a high-capacity power bank built for value. It delivers up to 25W fast charging (Power Delivery) and has 3 ports (2 USB-A and 1 bidirectional USB-C), enough to charge several devices at once. A digital display shows the remaining battery percentage, rare at this price. Its 20000mAh charge a smartphone about 3 to 4 times. Compact and offered at a low price, it is one of the best-selling large power banks.
The Baseus Bipow Pro is a bit of the value champion among large power banks. For under 30 euros, you get 20000mAh, 25W fast charging and above all a display showing the remaining percentage, a real comfort usually found only on far pricier models. In use, it charges a smartphone three to four times, enough for several days on the move. The 3 ports let you plug in two devices at once, and the USB-C port also recharges it. The body stays reasonably compact for the capacity. The downsides are typical for the price: the 25W power suits phones and tablets but not demanding laptops, and the plastic finish feels a touch less premium than Anker. But for large capacity at a low price, it is hard to do better.
Ugreen Nexode 45W
39.99€ 29.99€
(549)
The all-in-one power bank: 20000mAh, a built-in USB-C cable that doubles as a handle, 45W fast charging and a display to track it all.
- Capacity: 20,000 mAh (74 Wh)
- Power: 45W (PD 3.0), built-in cable
- Outputs: Built-in USB-C cable + USB-C + USB-A
- Weight: 468 g, LED display
- Built-in USB-C cable, 20000 mAh, 45W
The Ugreen Nexode 45W is a 20,000 mAh power bank with a built-in USB-C cable: no need to carry a cable, it is always there and even doubles as a carrying handle. It delivers 45W over Power Delivery to charge an iPhone past 50% in 30 minutes. With its three outputs (built-in cable, USB-C and USB-A), it powers three devices at once, and its LED display shows the remaining level. Compact (468 g) and under 100 Wh, it is allowed in the aircraft cabin: the ideal travel companion.
We slipped the Ugreen Nexode 45W into a weekend bag, and its appeal is obvious from day one: no more digging around for a cable, it is already there, built into the battery and ready to plug into an iPhone or a Galaxy. That detail genuinely changes life on the move, and the cable also works as a little handle to carry it. Charging is quick for this format: in half an hour you get back more than half a phone, and the LED display avoids nasty surprises, you see exactly the percentage left. The three outputs let you charge the phone, earbuds and tablet at the same time, welcome when you travel as a pair. We also like that at 468 g it stays reasonable for 20,000 mAh, and that it passes without trouble in the cabin. Two honest caveats: 45W is enough for a MacBook Air but not for a big laptop, and you have to supply your own wall charger to recharge it quickly (nothing is included beyond the built-in cable). But for a complete travel battery, with its cable always to hand and excellent value, the Nexode 45W is a real success.
Ugreen 300W 48000mAh
199.99€ 159.99€
(246)
Off-the-charts endurance: 48000mAh of LiFePO4, 300W to charge a laptop, a control display, an LED light and a carry handle.
- Capacity: 48,000 mAh (LiFePO4)
- Power: 300W, USB-C 140W (PD 3.1)
- Outputs: 3 USB ports, digital display
- Recharge: 140W bidirectional, 3000 cycles
- 48000 mAh, 300W, LED light, handle
The Ugreen 300W 48000mAh is a giant power bank, halfway between a power bank and a portable power station. With 48,000 mAh of LiFePO4 cells (3000 cycles) and 300W of total power, including a 140W USB-C port, it charges a laptop at full speed and several phones for days. It has a digital display, a three-mode LED light and a carry handle, making it an ideal companion for camping, the van or power cuts. For flights, its capacity (in the 100 to 160 Wh range) requires the airline's prior approval.
We took the Ugreen 300W 48000mAh on a weekend van trip, and it is the kind of battery that changes things when you are far from a socket: it charged the whole group's phones for two days, powered a laptop for a working day, and served as a backup light in the evening thanks to its built-in LED. The handle is well thought out for carrying it, and the display lets you track precisely what is left. We really like the LiFePO4 cells: you know you keep the battery for many years without it degrading. Recharging is quick for this size, about an hour and a half at 140W. On the other hand, you have to accept the weight and bulk, you do not slip it into a pocket, and for flying, its capacity requires the airline's prior approval. The price is significant, but relative to what it offers, it stays reasonable next to a power station. For anyone after a massive, durable USB reserve that is practical outdoors, it is an excellent choice.
Aukey PB-Y63 Spark Sling
103.99€
27600mAh and 140W fast charging, with a display and flight compatibility: the Aukey PB-Y63 is one of the largest power banks able to charge a laptop.
- Capacity: 27600mAh (about 99Wh)
- Power: 140W max (Power Delivery 3.1)
- Ports: USB-C + USB-A
- Extra: Digital display, flight-friendly
- 27600mAh and 140W to charge a laptop
The Aukey PB-Y63 Spark Sling is a very high-capacity 27600mAh power bank delivering up to 140W fast charging (Power Delivery 3.1). Enough to charge a laptop at full speed, including a MacBook Pro, on top of smartphones and tablets. It has a digital display showing power and runtime, and stays just under the 100Wh threshold, making it carry-on friendly. Note: the Aukey brand was banned from Amazon in 2021 and is now sold only via its own site.
The Aukey PB-Y63 is one of the most ambitious power banks on the market: 27600mAh, one of the largest capacities you can take on a plane, and 140W output, enough to charge a MacBook Pro or a USB-C laptop at full speed. In use, it is a real backup powerhouse: several smartphone charges, a laptop topped up effortlessly, and a display that clearly shows the power and remaining runtime. Staying under 100Wh is a real plus for travellers. Technically, it rivals the Anker 737. The main downside concerns the brand: Aukey was banned from Amazon in 2021 for fraudulent reviews, and is now sold only on its own European site. Availability and after-sales support are therefore less obvious than with Anker or Ugreen, which calls for comparison before buying.
RAVPower PD Pioneer 20000mAh
59.99€
20000mAh and 70W fast charging across 4 ports: the RAVPower PD Pioneer charges a laptop like a smartphone, by cable at full speed.
- Capacity: 20000mAh (74Wh)
- Power: 70W max (two-way fast charging)
- Ports: 2 USB-C + 2 USB-A
- Compatibility: Smartphones, tablets, laptops
- 70W and 4 ports to charge a laptop
The RAVPower PD Pioneer 20000mAh is a high-capacity power bank delivering up to 70W two-way fast charging. With its 4 ports (2 USB-C and 2 USB-A), it charges a laptop, a smartphone or a tablet at full speed, and can power several devices at once. Its 20000mAh offer a real reserve for several days. Note: the RAVPower brand was banned from Amazon in 2021 and remains hard to find in Europe.
The RAVPower PD Pioneer 20000mAh belongs to the generation of genuinely powerful power banks, able to charge a laptop and not just a phone. Its 70W output is a real asset: on a MacBook or a USB-C ultraportable, it charges at good speed, which conventional banks cannot do. Its 4 ports let you power several devices at once, and its 20000mAh capacity lasts several days on the move. Technically, it has nothing to envy the market benchmarks. The real problem is the brand: RAVPower was banned from Amazon in 2021 for fraudulent review practices, and is no longer really distributed in Europe. It is therefore hard to recommend today against alternatives like the Anker 737 or the INIU 65W, easier to buy and to get warranty support for.

Anker Nano 30W

- Capacity: 10,000 mAh (37 Wh)
- Power: 30 W (USB-C PD)
- Ports: Built-in USB-C cable + USB-C + USB-A
- Weight: 215 g
- Built-in USB-C cable, 30 W and a colour display

It delivers up to 30 W over USB-C Power Delivery to fast-charge a smartphone, a tablet, earbuds or even a light laptop. A colour display shows the remaining charge, and two extra ports (USB-C and USB-A) complement the built-in cable. Compact (215 g), bi-directional and made from recycled plastic, it is ideal for daily use and travel.
The Anker Nano 30W quickly won us over with how practical it is. The built-in USB-C cable is a genuine game-changer: no more digging for a cable at the bottom of the bag, it is always there, and it doubles as a loop to grab the battery. Day to day, the 30 W charge a smartphone quickly, you get half an iPhone's battery back in half an hour, and a tablet keeps up fine. The colour display is a real plus: you know exactly how much is left, no guessing with LEDs. With 10,000 mAh, you recharge a modern phone almost twice, plenty for a busy day or a light weekend. The pocket format and 215 g make it easy to take anywhere. Two honest reservations: the built-in cable, handy as it is, cannot be replaced if it wears out, and 30 W is a little tight to charge a large laptop at full speed. But for a smartphone and small devices, with this convenience and display, it is one of the most accomplished power banks in its class.
Ugreen Nexode 55W
59.99€ (490)
The small power bank that charges hard: 10000mAh, 55W, a built-in USB-C cable with strap and a digital display, smaller than an iPhone.
- Capacity: 10,000 mAh (37 Wh)
- Power: 55W (Xiaomi), PD 45W
- Outputs: Built-in USB-C cable + USB-C + USB-A
- Weight: 249 g, digital display
- 55W, built-in cable and display, 249 g
The Ugreen Nexode 55W is a compact 10,000 mAh power bank built for power: up to 55W to charge an iPhone 17 Pro Max to 66% in 30 minutes. Smaller than an iPhone 17 Pro Max at 249 g, it packs a built-in USB-C cable (with strap), a USB-C port and a USB-A port to power three devices at once, plus a digital display showing level and power in real time. Under 100 Wh, it is allowed in the aircraft cabin: the ideal premium pocket reserve.
We adopted the Ugreen Nexode 55W as our everyday battery, and its format wins you over at once: it fits in a jeans pocket, weighs barely 249 g, and yet charges faster than many bigger models. The built-in USB-C cable saves carrying a cable, and its little strap is handy for clipping it to a bag. In practice, you get back two thirds of an iPhone in half an hour, excellent for this size. The digital display is pleasant: you see at a glance the percentage left and the power going out, no more charging blind. The three outputs help out when you travel as a pair. Two honest caveats: with 10,000 mAh you get about one and a half iPhone charges, so for long days you will want something bigger, and its price is high for this capacity, you pay for the power, the display and the built-in cable. But for a small, fast, complete and well-made battery, the Nexode 55W is a success that never leaves the pocket.
EcoFlow Rapid 25K
103.99€ (61)
25,000 mAh, 170W and two built-in retractable USB-C cables: the power bank that recharges a MacBook twice and your phone five times, with no cable to carry.
- Capacity: 25,000 mAh (cabin approved)
- Output: 170W (2 ports), 100W on 1 port
- Cables: 2 built-in retractable USB-C cables
- Recharge: 0 to 50% in 26 min, TFT screen
- 170W, 2 built-in cables, screen
The EcoFlow Rapid 25K is an all-in-one power bank designed for travel and remote work. Its 25,000 mAh (allowed in the aircraft cabin) recharge a MacBook twice or a phone four to five times, enough to last one to two days away from an outlet. It delivers up to 170W across two ports (100W on a single port), charges up to four devices at once, and has two built-in retractable cables (a 67 cm USB-C and a 26 cm USB-C lanyard), so no need to carry extras. A clear TFT screen shows the charge level, and it recharges itself to 50% in 26 minutes.
The Rapid 25K won us over with its all-in-one nature: you slip it into the bag with nothing else, as it already carries two retractable cables, a 67 cm USB-C and a handy little 26 cm USB-C lanyard for earbuds or a phone. Its 25,000 mAh last one to two days of remote work, it recharged our MacBook twice and the phone several times without flagging. The 170W output (across two ports) lets you power a laptop while charging a phone alongside, which is rare at this price. The TFT screen is crisp and gives the remaining level at a glance. A nice surprise on recharging too: 50% back in 26 minutes, you get it going again quickly. Two caveats: at 170W it drains fast and warms up a little, like any battery of this power, and a single port caps at 100W (you need two ports to reach 170W). But for a complete travel bank, cable-self-sufficient and able to recharge a laptop, it offers excellent value.
EcoFlow Rapid Pro 27K
164.99€ (60)
27,650 mAh, 300W and a built-in 140W USB-C cable: the power bank that charges a laptop and three more devices at once, with a screen and app to boot.
- Capacity: 27,650 mAh (99.54 Wh)
- Output: 300W total, USB-C 140W max
- Ports: 4 USB-C ports, 1 built-in 140W cable
- Screen: LCD, EcoFlow app, cabin approved
- 300W, built-in 140W cable, screen
The EcoFlow Rapid Pro 27K is a premium power bank built for travel and remote work. With 27,650 mAh (99.54 Wh, allowed in the aircraft cabin) and 300W of output across four ports, it charges up to four devices at once, including a laptop over USB-C 140W. Its 60 cm 140W USB-C cable is built in, so no need to carry extras, and an LCD screen shows the charge level. Interchangeable magnetic cases, app control and express charging (80% in 20 minutes with the Rapid Pro 320W station) round out a power bank as powerful as it is practical.
The Rapid Pro 27K has become our go-to travel bank, and it owes that mainly to its built-in 140W USB-C cable: no more digging through the bag, you pull out the 60 cm cable and charge, laptop included. The 300W output across four ports lets you plug in a MacBook, a phone and a tablet at the same time without slowing down, real convenience on the move. Its 27,650 mAh (99.54 Wh) stays under the aircraft cabin limit, making it an ideal flight companion, and the LCD screen gives the remaining percentage at a glance, no guessing. Recharged on the Rapid Pro 320W station, it reaches 80% in about twenty minutes, spectacular. The interchangeable magnetic cases are a fun touch to personalise the look. Two honest caveats: at full power it warms up and drains fast (300W is huge for a power bank), and the price sits above classic power banks. But for anyone wanting a single battery able to recharge everything, laptop included, it is an excellent choice.
EcoFlow Rapid Pro X
£249.99 (8)
27,650mAh, 300W and a lightning-fast recharge: the Rapid Pro X powers your laptop and phone at once, and travels with you in the cabin.
- Capacity: 27,650 mAh (99.54 Wh)
- Power: 300 W total, up to 140 W per port
- Recharge: 0 to 80% in 40 min (140 W USB-C)
- Outputs: 4 USB-C ports, incl. retractable cable
- Premium travel bank: LCD screen, app and X-Guard safety
Built for demanding travellers, the EcoFlow Rapid Pro X is a premium power bank that recharges a laptop at full speed, powers several devices at once, and slips into a bag with ease. Its built-in retractable USB-C cable, LCD screen and companion app make it a complete travel partner, cabin-approved thanks to a capacity just under the 100 Wh limit. Ideal for mobile remote work, content creators and long journeys.
After carrying the Rapid Pro X across several trips, one thing is clear: this is a power bank built first for laptops. Plugged into the 140 W port, my MacBook charged almost as fast as with its wall charger, while also topping up my phone and earbuds at the same time. The LCD screen is a real everyday plus: you see remaining charge and the power drawn by each port at a glance, and the built-in retractable cable saves rummaging through the bag. When travelling, its capacity just under 100 Wh let me keep it in carry-on with no questions at boarding. Recharging is impressive, especially with the 320 W station: a coffee break and it is ready again. Two honest downsides: it is expensive and fairly heavy for a power bank (around 700 g, you feel it in the bag), and the screen scratches easily if left loose without a case. Otherwise, for mobile remote work or a creator kit, it is one of the most complete and fastest power banks I have used.

Xtorm XR104
59.99€ (27)
A rugged 10,000 mAh power bank with a built-in solar panel, LED torch and 3 USB outputs, designed for hiking and camping.
- Capacity: 10,000 mAh (Li-polymer)
- Power: 20 W max (USB-C PD, QC 3.0)
- Outputs: 1 USB-C + 2 USB-A (3 devices)
- Recharging: USB-C (3.5 h) or built-in solar panel
- 10,000 mAh with solar panel, LED torch, rugged, 3 outputs
The Xtorm XR104 is a 10,000 mAh outdoor power bank (Xtreme Series) that combines three assets for the wild: a built-in solar panel for backup power, a powerful LED torch and a rugged body that resists knocks and water splashes. It delivers up to 20 W on its USB-C port (Power Delivery) and offers three outputs (1 USB-C, 2 USB-A) to charge several devices at once. Supplied with a carabiner, it clips onto a backpack and follows you anywhere on a hike, a camp or a trek.
We tested the Xtorm XR104 as an adventurer's battery, and that is exactly where it makes sense. The rubberised body inspires confidence: it takes knocks, resists water splashes and dust, and the supplied carabiner lets you clip it onto a backpack to charge while walking. The built-in LED torch is a real bonus at a bivouac, handy for lighting a tent or getting by at night. On wired charging, the 20 W over USB-C top up a smartphone at a good pace, and being able to plug in three devices at once (1 USB-C, 2 USB-A) helps when there are several of you. The 10,000 mAh give around two full phone charges. Let us be honest about the solar: the small built-in panel is a backup to a backup, recovering a few Wh on a sunny day, enough to scrape a little range in a pinch, but not enough to fill the battery in the sun (count on USB-C to top it up fully). Seen for what it is, a solid outdoor battery with solar backup and a torch rather than a true solar charger, the XR104 is a reassuring, versatile companion in the wild.
V - Cheap power banks
Even with a limited budget, it is possible to find excellent external batteries. Some do not compromise on performance or quality despite their price. Here is our top of the most affordable power banks, accessible to all.
Varta Energy 5000
14.99€ (5698)
A simple, affordable 5,000 mAh power bank from Varta, with two USB-A ports, a USB-C and enough to charge up to three devices.
- Capacity: 5,000 mAh (Li-polymer)
- Outputs: 2 USB-A + 1 USB-C (up to 15 W)
- Recharging: USB-C or micro-USB (cable included)
- Simultaneous charging: Up to 3 devices
- 5,000 mAh, 2 USB-A + USB-C, 3 devices, budget price
The Varta Power Bank Energy 5000 (reference 57975) is a compact 5,000 mAh power bank with unbeatable value for money. It offers two USB-A ports and a bi-directional USB-C port (input and output), plus a micro-USB input, and can power up to three devices at once, with charging power up to 15 W. Slim and light in its white shell, with four charge LEDs and a cable included, it is ideal as a reliable everyday backup battery without breaking the bank.
We tested the Varta Energy 5000 as what it is: a simple, reliable, cheap backup battery. And on that ground, it ticks the right boxes. The format is slim and light, it slips easily into a pocket or a bag, and the white shell has a decent finish for the price. On connectivity, we like the versatility: two USB-A ports and a bi-directional USB-C let you recharge the battery as well as power devices, and the micro-USB input helps out with older cables. Being able to plug in up to three devices at once is a real bonus when travelling in a group. The 5,000 mAh give around one full phone charge, sometimes a little more on small phones: it is the typical top-up to see out a day. Two honest reservations: the capacity stays modest (do not count on it for a whole weekend without a socket), and the 15 W power suits topping up without working miracles on fast charging. But for a serious backup battery, from a well-known brand and at a very low price, the Varta Energy 5000 is a smart choice.
Intenso XS10000
16.99€ (4320)
A compact 10,000 mAh power bank from Intenso, with a bi-directional USB-C port, a USB-A and an LED display, at a budget price.
- Capacity: 10,000 mAh (Li-polymer)
- Outputs: USB-C (in/out) + USB-A
- Power: Up to 15 W (5V / 3.1A total)
- Recharging: USB-C or micro-USB (cable included)
- 10,000 mAh, USB-C in/out + USB-A, 4 LEDs, compact and cheap
The Intenso XS10000 (reference 7313530) is a compact 10,000 mAh power bank with great value for money. In a pocket-sized white shell, it combines a bi-directional USB-C port (input and output), a USB-A port and a micro-USB input, with power up to 15 W. Four LEDs show the charge level, a USB-A to USB-C cable is included, and built-in protections (overcharge, over-discharge, short circuit) ensure worry-free use. Ideal as a reliable everyday backup battery, without breaking the bank.
We tested the Intenso XS10000 as an everyday backup battery, and for the price, it does the job without a false note. The format is genuinely compact: a little brick that fits in the palm and slips into a jacket pocket or a bag without a thought. The white shell has a simple but decent finish, and the four LEDs tell you the remaining level at a glance. On connectivity, we like the bi-directional USB-C port, which both recharges the battery and powers a device, alongside a USB-A port and a micro-USB input for older cables. A USB-A to USB-C cable is included in the box, which saves an extra purchase. The 10,000 mAh give around two full phone charges, enough to see out a busy day or even a light weekend. The 15 W power suits topping up without aiming for ultra-fast charging, and the capacity is honest, right in the average for the format. A well-known German brand, built-in protections and a contained price: for a simple, reliable backup battery, the Intenso XS10000 is a smart choice.
VI - Wireless power banks
Induction charging technology (also known as IQ or Wireless charging) lets you charge compatible smartphones wirelessly by simply placing them on the charger. In this section, you will find mobile batteries capable of induction charging.
Ugreen Nexode 10000mAh
34.99€ 29.99€
(17042)
A magnetic MagSafe-compatible power bank: 10,000 mAh, wireless charging for iPhone, 20W USB-C and a built-in foldable stand, in an ultra-thin design.
- Capacity: 10,000 mAh (~37 Wh)
- Wireless charging: Magnetic MagSafe, 7.5W
- Wired charging: USB-C Power Delivery 20W
- Format: Ultra-thin 19 mm, 220 g, foldable stand
- MagSafe + 20W USB-C, foldable stand, ultra-thin
The Ugreen Nexode is a 10,000 mAh magnetic power bank designed for iPhone: it clips onto the back of the phone via its MagSafe-compatible magnets and charges it wirelessly, cable-free. Wired, its USB-C port delivers 20W Power Delivery for fast charging, and can power two devices at once. Ultra-thin (19 mm) and light (220 g), with a built-in foldable stand and a non-slip silicone surface, it is the ideal backup to slip into a pocket.
We adopted the Ugreen Nexode as a backup battery for the iPhone, and its appeal is obvious the moment you place it on the back of the phone: the MagSafe magnets align it perfectly and hold it firmly, and you can keep using the iPhone while it charges, with no dangling cable. The format is genuinely thin and light, it disappears into a pocket. The little foldable stand is a nice surprise: you prop the phone in landscape to watch a video while it charges. Over USB-C, the 20W charge the iPhone quickly (or a second device at the same time), and also recharge the battery itself. Two honest caveats: wireless charging tops out at 7.5W on iPhone, fine for topping up but not the fastest (use USB-C if you are in a hurry), and it warms up a little during heavy magnetic charging. There is no screen, just LED level indicators. But at this price, to keep an iPhone topped up wirelessly day to day, the Nexode offers excellent value.
Anker MagGo Power Bank
£54.99 (8328)
10000mAh that snap onto the back of an iPhone via MagSafe and charge it wirelessly at 15W: the Anker MagGo magnetic power bank, with a display and built-in kickstand.
- Capacity: 10000mAh
- Wireless: MagSafe / Qi2 15W (magnetic)
- Wired: USB-C 30W (input and output)
- Extra: Display + built-in kickstand
- MagSafe 15W wireless charging with kickstand
The Anker MagGo Power Bank is a 10000mAh magnetic power bank designed for MagSafe-compatible iPhones. Qi2 certified, it charges wirelessly at 15W by snapping magnetically to the back of the phone, and also offers a USB-C port up to 30W for fast wired charging (input and output). It has a display showing battery level and remaining charge time, plus a foldable kickstand to use the phone in landscape while charging.
The MagGo is the power bank that finally made magnetic charging genuinely practical. You slap it onto the back of the iPhone, it holds perfectly thanks to the MagSafe magnet, and you keep using the phone while it charges wirelessly at 15W, with no dangling cable. The built-in kickstand is a brilliant little touch: you prop the iPhone in landscape to watch a video while charging. The display showing the remaining percentage saves you from guessing. Its 10000mAh charge an iPhone about 1.8 times, enough for a good day. To go faster, the 30W USB-C port allows full-speed wired charging. The downsides are those of any MagSafe bank: wireless charging warms up a little and is less efficient than wired, and the magnet is mainly optimised for iPhone. But for an Apple user, it is the perfect on-the-go accessory.
Ugreen MagFlow 10000mAh
89.99€ 63.99€
(1818)
The fastest MagSafe charging: 10000mAh, Qi2 25W magnetic wireless charging for iPhone, a built-in USB-C cable and a digital display.
- Capacity: 10,000 mAh (37 Wh)
- Wireless charging: Magnetic Qi2 25W (MagSafe)
- Wired charging: USB-C PD 30W, built-in cable
- Weight: 250 g, digital display
- Qi2 25W wireless, built-in cable, display
The Ugreen MagFlow 10000mAh finally brings genuinely fast wireless charging to the MagSafe world: thanks to the Qi2 standard, its magnetic charging reaches 25W, against 7.5W on most magnetic batteries. It charges an iPhone 17 Pro Max to 50% in 38 minutes, cable-free. A built-in USB-C cable (30W, doubling as a strap) and a USB-C port complete the 3-in-1 design, and a digital display shows the level. Compact (250 g) and under 100 Wh, it is allowed in the aircraft cabin: the most complete magnetic battery.
We adopted the Ugreen MagFlow as our main MagSafe battery, and the difference from 7.5W models is obvious: at 25W wireless, the iPhone charges genuinely fast, you get back half the battery in a short half hour without plugging in a single cable. The magnets hold firmly, you keep the phone in hand without it sliding. The built-in USB-C cable is well thought out, it also acts as a strap and saves carrying a cable, and the digital display lets you track the level at a glance. The format stays reasonable, it slips into a pocket. Two small caveats: full Qi2 25W charging is only available on recent iPhone 16 and 17 (iOS 26), older models staying at 15W, which is already good, and it warms up a little during fast charging, like any battery of this type. But for the fastest magnetic wireless charging, with cable and display, it is currently one of the best on the market.
Ugreen Nexode Mini 5000mAh
59.99€ (1400)
The ultra-thin MagSafe power bank: 5000mAh, magnetic wireless charging for iPhone, a USB-C 60W cable included, in a format you forget.
- Capacity: 5,000 mAh (18.5 Wh)
- Wireless charging: Magnetic MagSafe 7.5W
- Wired charging: USB-C 15W, 60W cable included
- Format: Ultra-thin 1.31 cm, soft-touch silicone
- Ultra-thin, MagSafe, USB-C 60W cable included
The Ugreen Nexode Mini 5000mAh is an ultra-thin magnetic power bank for iPhone: it attaches to the back of the phone via its MagSafe magnets and charges it wirelessly at 7.5W. A USB-C port handles wired charging up to 15W, and a USB-C 60W cable is included in the box, which is rare. Barely 1.31 cm thick, with a soft-touch silicone surface, it gives about one iPhone charge to slip in a pocket. Under 100 Wh, it is allowed in the aircraft cabin.
We adopted the Ugreen Nexode Mini as a backup battery for the iPhone, and it is the ideal companion for days when you travel light. You slap it onto the back of the phone, the MagSafe magnets align it perfectly, and you keep using the iPhone while it charges wirelessly, with no dangling cable. What strikes you first is how thin it is: barely thicker than a slightly generous case, it does not unbalance the phone in hand and vanishes into a pocket. The soft-touch silicone finish is pleasant and grippy. We also like that the USB-C cable is included, which is far from standard, handy for wired charging at 15W. Two honest caveats: wireless charging stays at 7.5W, fine for topping up but not the fastest on the market (some rivals reach 15W), and with 5,000 mAh you get about one iPhone charge. It is also a little pricey for its class. But for a genuinely thin, well-finished magnetic battery that is complete out of the box, the Nexode Mini appeals to those who value lightness and a carefully made object.
Samsung 10,000 mAh (wireless)
49.90€ 39.99€
(130)
Charge wirelessly or over 25 W USB-C, up to three devices at once, with the compact and elegant Samsung 10,000 mAh wireless battery pack.
- Capacity: 10,000 mAh
- Wireless charging: Qi induction, 7.5 W
- Wired output: 2 USB-C, 25 W max
- Weight: 222 g
- Qi wireless + 2 USB-C 25 W, up to 3 devices at once
The Samsung 10,000 mAh wireless battery pack (reference EB-U2510) combines two charging modes: a Qi induction surface (7.5 W) to rest a phone, a watch or earbuds directly on it, and two wired USB-C ports up to 25 W. It can power three devices at once, two wired and one wireless. Compact (222 g), finished in an elegant beige and partly made from recycled plastics, it is ideal for fast charging day to day and on the move, USB-C cable included.
We took to this Samsung induction battery for its two-in-one nature. Day to day, simply dropping the phone on top to charge it, with no cable to find, is genuinely pleasant, just like charging a Galaxy Watch or earbuds the same way. And when you want speed, the 25 W USB-C ports do the job: you get a good chunk of a phone's battery back in little time. Being able to power three devices at once (two cables plus induction) is a real help when travelling, when everyone needs juice. The LED indicators are clear, you always know how much is left, and the included cable saves carrying one. The beige finish is pretty and a change from the usual black shells. Two honest reservations: induction charging is handy but slow (7.5 W), so for speed you are better off using USB-C, and at 222 g it makes itself felt in a small pocket. But for mixed wireless and wired use, with this capacity and versatility, it is a genuinely well-designed power bank.
EcoFlow Rapid Mag 10000mAh
76.99€ (80)
Next-generation magnetic wireless charging: Qi2.2 25W, 10,000 mAh, a built-in 36W USB-C cable and a folding stand, in an ultra-thin 230 g body.
- Capacity: 10,000 mAh (iPhone 16 x1.9)
- Wireless: Qi2.2 25W magnetic (11N magnet)
- Wired: Built-in 36W USB-C cable, 3 devices
- Format: 230 g, 15.95 mm, built-in stand
- Qi2.2 25W, built-in cable, stand
The EcoFlow Rapid Mag is a magnetic power bank that adopts the latest Qi2.2 standard: its wireless charging reaches 25W, more than three times faster than first-generation Qi, and fully optimised for recent iPhones. Its 10,000 mAh recharge an iPhone 16 up to 1.9 times, in an ultra-thin 230 g body that slips into a pocket. A 36W USB-C cable is built into the body, a strong 11N magnet holds the phone firmly, and a retractable stand keeps the screen upright or landscape, hands-free. It charges the phone while recharging itself.
The Rapid Mag reconciled us with magnetic wireless charging, often too slow on rival banks: here, thanks to Qi2.2, you get 25W wirelessly, and the difference shows, the iPhone climbs back up genuinely fast without a single cable. You snap it onto the back of the phone, the 11N magnet holds firm even while walking or cycling, and the small retractable stand is an excellent idea for watching a video while charging, portrait or landscape. The built-in 36W USB-C cable avoids carrying a cord, and you can power up to three devices by combining wireless and wired. Its 10,000 mAh in a 230 g, 15.95 mm-thick body make it a true pocket battery, recharging an iPhone 16 nearly twice. It charges itself while powering the phone, handy at night on the bedside table. Two caveats: full 25W is mainly used by recent iPhones (Qi2.2), and like any magnetic bank it warms up a little during fast charging. But for genuinely fast, portable wireless charging, it is a success.
VII - Multi-function devices
Below you will find devices whose primary role isn't to act as an external battery for charging your devices, but which, in addition to their main function, are also able to do so. Here is our selection of these highly versatile devices.
JBL Charge 5
148.04€ (25875)
JBL's most popular portable speaker: 40W of powerful sound, IP67 waterproofing, 20 hours of battery life and a power bank function to charge your phone.
- Power: 40 W (30 W + 2 x 5 W)
- Battery life: 20 h (7500 mAh battery)
- Functions: Speaker, USB-A power bank, IP67 waterproof
- Connectivity: Bluetooth 5.1, PartyBoost
- 40W sound, IP67, 20h and USB phone charging
The JBL Charge 5 is a portable Bluetooth speaker that has become a benchmark: rich 40W sound (racetrack driver and two tweeters), 20 hours of battery life and IP67 waterproofing that shrugs off water and dust. Its 7500 mAh battery doubles as a power bank, via a USB-A port, to charge a phone during the day. With Bluetooth 5.1 and PartyBoost, it pairs with other compatible JBL speakers for bigger sound.
We took the Charge 5 everywhere, and that is exactly what it is built for. On a terrace or by the pool, the sound really carries: the 40W fill a garden without distorting, with bass that is genuinely present for a speaker this size. The IP67 rating reassured us more than once, between a surprise shower while camping and splashes at the water's edge, it takes it all in stride. Battery life lives up to the claim: on a full day out we never had to recharge it, and the 20 hours are realistic at a reasonable volume. The little extra that places it among multi-function devices is the USB-A port that rescues a dead smartphone, very handy on a hike or at a festival. Two honest downsides: there is no aux input and no microphone for calls, and at full volume the battery drains a bit faster. But for generous sound, a rugged build and real portable versatility, the Charge 5 remains a safe bet.
JBL Xtreme 3
330.99€ (6241)
The most powerful speaker in JBL's portable line-up: 100W of immersive sound, IP67 waterproofing, 15h of battery life, a shoulder strap and a power bank function.
- Power: 100 W (4 speakers)
- Battery life: 15 h (10000 mAh battery)
- Functions: Speaker, USB-A power bank, IP67 waterproof
- Connectivity: Bluetooth 5.1, PartyBoost
- Immersive 100W sound, IP67, strap and power bank
The JBL Xtreme 3 is the heavyweight of the brand's portable Bluetooth speakers: 100W of power driven by four speakers and two passive radiators, for immersive sound and deep bass. IP67 waterproof, it offers 15 hours of battery life and a large battery that also works as a power bank via a USB port. Supplied with a rugged shoulder strap featuring a bottle opener, it is built for parties, the beach and big outdoor gatherings.
When you bring out the Xtreme 3, you do not go unnoticed, and that is the whole point. With its 100W and four speakers, it puts out full sound and bass that moves air: enough to fill an entire garden or a table of twenty people without ever straining. We used it a lot outdoors, and its IP67 rating let us set it down by the pool without worry. The supplied shoulder strap, with its built-in bottle opener, is a real plus for carrying it around, even if at nearly 2 kg you feel it on your shoulder. The USB rescue port saved more than one phone at the end of the evening, which clearly places it among multi-function devices. The 15-hour battery life is decent given the power, but at full volume it drops faster. Two honest downsides: it is bulky and heavy, and its price sits at the top of the range. But for anyone after big, long-lasting portable sound, the Xtreme 3 delivers on its promises.
JBL Charge 6
159.99€ (3911)
JBL's new portable benchmark: AI-boosted sound, upgraded IP68 waterproofing, 28 hours of battery life, a removable strap and a USB-C power bank function.
- Power: 45 W RMS (up to 180 W peak, AI Boost)
- Battery life: 28 h (24 h + 4 h AI Boost)
- Functions: Speaker, USB-C power bank, IP68 waterproof
- Connectivity: Bluetooth 5.4, Auracast
- IP68, 28h, Auracast, removable strap and USB-C power bank
The JBL Charge 6 succeeds the famous Charge 5 and raises the bar across the board: upgraded IP68 waterproofing, 28 hours of battery life (24h + 4h thanks to AI Sound Boost), Bluetooth 5.4 with Auracast and a new removable carry strap. Its USB-C port doubles as a power bank output to charge a smartphone, and also accepts high-quality wired audio. A true multi-function device, built for the outdoors.
After years of faithful service from the Charge 5, we were watching the Charge 6 closely, and JBL delivered. The sound has grown fuller: AI Sound Boost pushes peak power and you feel more generous bass, a more open presentation at higher volumes. On a day at the beach, the IP68 rating (now protected against prolonged submersion) reassured us, and the removable strap, the real novelty, is a game changer for hanging it on a bag or a branch. The 28-hour battery life is comfortable: you get through a camping weekend with little recharging. The power bank function moves to USB-C, more universal, and the same port also serves as a quality wired audio input. On connectivity, Auracast replaces PartyBoost and broadcasts to a near-unlimited number of compatible speakers. Two reservations: the price creeps up compared with the Charge 5, and there is still no microphone for calls. But as a multi-function portable speaker, the Charge 6 is a fine evolution.
Olight Olantern Classic 2 Pro
172.04€ (30)
A retro-style camping lantern, dimmable from 10 to 300 lm, controlled by app, with a genuine 18W power bank function to recharge your devices.
- Brightness: 10-300 lm (warm white + orange)
- Runtime: up to 220 h
- Power bank: 18 W (USB-C + USB-A)
- Control: App + rotary knob
- Retro dimmable lantern and 18W power bank, app-controlled
The Olight Olantern Classic 2 Pro is a retro-style LED camping lantern built around versatility. Its light dims steplessly from 10 to 300 lumens, from warm white to ambient orange, via a rotary knob or the smartphone app (battery level, timer, sleep mode). Its large built-in battery provides up to 220 hours of runtime and also works as an 18W power bank, with USB-C and USB-A outputs to charge a phone. A true multi-function device for camping and power cuts.
We have a real soft spot for this Olantern Classic 2 Pro, as much for its looks as for what it can do. The retro copper style looks great on a camping table or a shelf at home, and the light is superb: the knob lets you dial in the mood precisely, from warm white for reading to soft orange for an evening. App control is a clever touch, you check the battery level and set a timer without getting up. What places it among multi-function devices is its power bank function: with USB-C and USB-A outputs up to 18W, it recharged our phones during a weekend out in nature, a real plus when you are far from an outlet. Runtime is impressive in eco mode, holding several nights without a recharge. Two honest reservations: it is fairly heavy for a lantern, and its price sits above basic camping lights. But for the quality of light, the style and the dual lighting-battery role, it is well worth a look.
Tronsmart Bang 2
117.00€ (27)
A 90W portable party speaker, IPX6 waterproof, up to 26h battery life, with beat-synced RGB lighting and a power bank function to recharge your devices.
- Power: 90 W (2.1 channel, up to 105 dB)
- Battery life: Up to 26 h (18,000 mAh battery)
- Functions: Speaker, USB power bank, RGB lighting
- Connectivity: Bluetooth 5.3, TWS, IPX6 waterproof
- 90W IPX6 speaker, 26h, RGB lighting and power bank function
The Tronsmart Bang 2 is a Bluetooth party speaker that plays on every front: 90W of power (a 2.1 system with BassUp, up to 105 dB), a large 18,000 mAh battery giving up to 26h of playtime, and a power bank function to recharge a smartphone over USB. IPX6 waterproof, with beat-synced RGB lighting, Bluetooth 5.3 and wireless pairing of more than 100 speakers, it carries thanks to its handle and detachable strap, to liven up parties, the beach and camping.
We took the Tronsmart Bang 2 for what it is, a generous party speaker, and it genuinely delivers. The 90W have real punch: the sound carries far outdoors, the BassUp function gives bass that hits, and at up to 105 dB it easily fills a garden or a beach. Battery life is a real strong point: with its big 18,000 mAh battery, it lasts a whole evening (and far more at moderate volume) without hunting for a socket. The beat-synced RGB lighting adds a nice touch for the mood, and adjusts in the app, as does the equaliser. What places it among multi-function devices is its power bank function: a USB port recharges a phone, handy when the group's batteries run low late in the night. IPX6 waterproof, it fears neither splashes nor rain, and the detachable strap makes it easy to carry. Two honest nuances: at full power with the LEDs on, the runtime naturally drops, and at nearly 3 kg it is not a pocket mini-speaker. But to liven up parties while rescuing phones, the Bang 2 offers an excellent sound-features-price ratio.
Nitecore LR70
114.99€ (18)
Three devices in one: a 3000 lm flashlight, a 360-degree camping lantern and a 10,000 mAh power bank, all rechargeable over USB-C.
- Capacity: 10,000 mAh (2x 21700 cells)
- Lighting: 3000 lm flashlight, 400 lm lantern + red
- Functions: Flashlight, 360-degree lantern, USB-C power bank
- Durability: IP67, 1 m drop, 271 g
- 3-in-1: 400 lm lantern, 3000 lm flashlight, 10000 mAh power bank
The Nitecore LR70 is a clever 3-in-1 device that combines a powerful flashlight (up to 3000 lumens, two Luminus SST40 LEDs), a 360-degree camping lantern (up to 400 lumens, with red and SOS modes) and a 10,000 mAh power bank able to recharge a smartphone via its USB-C port. Compact (271 g) and rugged (IP67 waterproof, resistant to 1 m drops), it recharges itself over USB-C and becomes the ideal companion for camping, bivouacs and emergencies.
We loved the Nitecore LR70 for its Swiss-army-knife take on light. Hiking or camping, having in a single object a flashlight that can light up 300 m away and a mood lantern that glows at 360 degrees genuinely changes things: you light the path, then set the device down in the tent for a warm, pleasant light, without carrying two accessories. The 3000 lumens in Turbo are stunning for the size, and the lantern modes (soft white, plus red, SOS and beacon) are perfect at a bivouac or in a pinch. The power-bank function is the third asset: the 10,000 mAh recharge a smartphone over USB-C, enough to save the day when things get tricky. The build inspires confidence, IP67 waterproof and impact-resistant, and USB-C charging is handy. Two honest nuances: at full power, the runtime drops fast (Turbo is made for short bursts), and at 271 g it is not the lightest accessory. But for anyone wanting a single device that lights up strongly, illuminates a camp and rescues phones, the LR70 is a versatile success.

How do you choose an external battery? First, take stock of your needs. Does the power bank need to be compact enough to fit in your pocket, or does capacity matter more than size? How many times do you want to recharge your smartphone (check its capacity in mAh)? Do you need fast charging? Finally, factor in your budget, and with our help you'll know which external battery to choose.
All external batteries recharge via a simple USB port. Whether it uses a micro-USB cable or a USB-C cable (rarer), any power bank can be recharged on the same wall charger as your smartphone, or on any device with a USB port, such as your computer. This simplicity explains the great success of this type of battery.
External batteries are most often made up of one or more cells (often 18650-type cells) wired in parallel, with a sophisticated electronic circuit (managing charge and discharge, with integrated protection circuits), all enclosed in a protective shell. Their characteristics generally depend on the number of cells and the electronic circuit.
