Very high-capacity and expandable stations

Here the capacity of the station itself matters less than the capacity it can reach once the add-on batteries are connected.

These systems are built to grow with the need: start with the main unit, add one or more expansion batteries, and capacity climbs from 2 to 25 kilowatt-hours depending on the range. This is the entry point to full household backup, and the only format that can keep a house running for several days. The things to examine are the real cost of each added kilowatt-hour, often better value than the base unit, the output power which must keep pace with the growing capacity, and the connection method: some models wire into a dedicated panel, others remain limited to their own sockets.

No product matches these criteria.

Anker SOLIX F3800

See price and availability (11)

3840Wh, 6000W and up to 26.9kWh per unit with BP3800 batteries (53.8kWh combined): the Anker power station built to back up an entire home.

  • Capacity: 3840Wh (LiFePO4, expandable to 26.9kWh)
  • Power: 6000W continuous, 9000W peak
  • Expansion: Up to 6 BP3800 batteries (3840Wh each)
  • Charging: 0 to 100% in 77 min on mains (2990W)
  • Expandable to 26.9kWh per unit, 53.8kWh combined
The Anker SOLIX F3800 is a premium portable power station designed for home backup and heavy energy needs. Its LiFePO4 battery delivers 3840Wh and outputs 6000W continuous (9000W peak), expandable to 26.9kWh with up to six Anker SOLIX BP3800 batteries, or 53.8kWh by linking two units. It charges at up to 2990W from the mains (full charge in 77 minutes) and up to 2400W from solar. Mounted on wheels with a telescopic handle, it includes UPS switching and app control.
In-depth reviewRead our full review → 4.1/5 We used the Anker SOLIX F3800 as a home backup power source, and its output impresses straight away: oven, kettle and power tools all run without a hiccup, the 6000W handles everything. Mains charging is a real strength, at full power it tops up in just over an hour, handy ahead of a storm warning. The wheels and telescopic handle help a lot given its 60kg weight, though once it's set up you rarely move it again. The BP3800 expansion changes the equation: you start at 3840Wh and can scale up considerably depending on budget, a genuine step by step investment. Two honest drawbacks: the price climbs fast with each expansion battery, and a proper automatic switchover on the household panel needs a separate transfer kit. For a large, expandable home energy reserve, it remains a solid choice.

EcoFlow Delta Pro

£2499.00 (10)

3600Wh expandable to 25kWh, 3600W (4500W with X-Boost): the base of a home backup system, with a battery rated for 6500 cycles.

  • Capacity: 3600 Wh, expandable up to 25 kWh
  • Power: 3600 W (4500 W with X-Boost)
  • Recharge: Up to 6500 W (AC + solar + generator)
  • Endurance: 6500 cycles (50% remaining capacity)
  • Expandable to 25kWh, growing home ecosystem
The EcoFlow Delta Pro is a 3600Wh portable power station, expandable up to 25kWh via extra batteries and pairing two units. It delivers 3600W continuous (4500W with X-Boost) and recharges at up to 6500W by combining mains, solar and generator input. Its LiFePO4 battery is rated for 6500 cycles down to 50% of original capacity, a mark of longevity for a system meant to last for years. Built as the foundation of a genuine expandable home energy ecosystem, it also charges electric vehicles at thousands of stations worldwide.
In-depth reviewRead our full review → 4.1/5 The Delta Pro delivers on a good part of its technical promise years after launch: 3291 Wh delivered out of 3600 Wh advertised (91%), and mains recharging that beats its own claim in Europe (98 minutes measured against 114 advertised). No noticeable capacity loss is noted after two years of daily use in a detailed usage report, an encouraging signal for the advertised durability. The best-batteries.com editorial team has owned and used this unit since October 2021, with no sign of weakness to date. Two serious reservations before buying. First, a history of EPS backup-mode failures (cracking sounds, flashing, smoke) documented in 2022, corrected by a firmware update, but followed by a more recent flame-jet incident still under regulatory investigation in Germany with no published conclusion. Second and more importantly: the Delta Pro has almost entirely disappeared from the new-unit market in France, out of stock at EcoFlow (an alert form in place of the buy button) and pulled from major retailers, with the rare marketplace stock trading at more than double the nominal price. Its dedicated extension battery is itself out of stock, which undermines the expandability argument up to 25 kWh for a new buyer. The secondhand market between private individuals in France remains active and reasonably priced (1200 to £1585), a more realistic alternative than a new purchase today.

Jackery Explorer 2000 Plus

See price and availability (8)

Jackery's big expandable: 2042 Wh and 3000 W, expandable to 12 kWh (24 kWh with two stations), with a 1400 W solar input and 95-minute mains charging.

  • Capacity: 2042 Wh (LiFePO4, expandable to 12 kWh)
  • Power: 3000 W (surge 6000 W)
  • Solar: Up to 1400 W (2 inputs)
  • Recharge: 0 to 100% in 95 min (mains)
  • Expandable to 12 kWh, 24 kWh with two stations
The Jackery Explorer 2000 Plus is a premium station built to last and grow with your needs. Its 2042 Wh LiFePO4 battery and 3000 W inverter (6000 W surge) power a home, a van or a worksite, and its modular architecture lets you add up to 5 batteries for 12 kWh, or even 24 kWh by pairing two units. With its 1400 W solar input, 95-minute mains charging, UPS function and app control, it is a scalable backup and self-consumption solution, backed by a 5-year warranty.
In-depth reviewRead our full review → 4.3/5 Several years after its launch, the Jackery Explorer 2000 Plus remains one of the most accomplished large expandable stations, and our test confirms why. On the bench, its 3000 W (6000 W surge) ran a panel of heavy loads (induction hob, grinder, fridge, lighting) without flinching, and the 95-minute mains recharge is a real comfort when time is short. Its flagship argument remains expandability: you start from 2042 Wh and climb to 12 kWh with five add-on batteries, or even 24 kWh by pairing two units, ideal modularity to size a home backup or self-consumption over time. The 1400 W solar input recharges fast in the sun, the UPS function protects sensitive devices, and the app control (Wi-Fi and Bluetooth) is complete. A few honest caveats: the weight (27.9 kg, thankfully on wheels with a telescopic handle, though grip feels less confident once the ground turns uneven), and a bigger point worth flagging before you go looking for one: Jackery has pulled the 2000 Plus from new sale in France and the UK, pointing buyers instead to the lighter but non-expandable Explorer 2000 v2, while it remains on sale new in Germany. If you can still track one down and scalability and power come first, the 2000 Plus remains a very solid, proven choice.

Aferiy P310

See price and availability (8)

With 3840 Wh expandable to 11520 Wh, 3600 W (7200 W peak) and a 7 year warranty, the Aferiy P310 aims for accessible high end power.

  • Capacity: 3840 Wh (expandable to 11520 Wh), LiFePO4
  • AC output: 3600 W, up to 7200 W peak, pure sine wave
  • Ports: 3 AC outlets, 4 USB-C (100 W), 2 USB-A, XT60, DC
  • Warranty: 7 years, UPS function (under 10 ms switchover)
  • 3840 Wh expandable to 11520 Wh, 7 year warranty
The Aferiy P310 is a high end portable power station with 3840 Wh of LiFePO4 capacity (4000 cycles), expandable up to 11520 Wh with additional batteries. It delivers 3600 W continuous and up to 7200 W peak, with a UPS function that switches over in under 10 ms. Its 13 outputs (3 AC outlets, 4 USB-C including one 100 W, 2 USB-A, DC5521, XT60, car socket) accept up to 2000 W of solar input and are controlled via the app. 7 year warranty, 40 kg with wheels and a telescopic handle.
In-depth reviewRead our full review → 4.2/5 We unboxed the Aferiy P310 with a bit of apprehension: at 40 kg, it earns its keep on delivery day. Once out of the box, the build quality reassures straight away, sturdy casing, a solid telescoping handle and wheels that genuinely roll on flat ground or a deck. During a simulated power cut, the UPS switchover held without so much as a flicker on the connected laptop's screen, a real strength for anyone wanting to secure a home office or a fridge. The 3600 W continuous output swallowed a kettle and an induction hob running at once without flinching, something few stations at this price manage. The app is simple, and charging at 2200 W on mains power is genuinely impressive. Two honest gripes: the weight limits it to near stationary use (garage, van, workshop), and Aferiy's after sales support, responsive in our exchanges, remains less known than the big brands. For anyone after a serious home backup or motorhome power source, backed by a 7 year warranty, it remains a very solid choice.

Pecron F3000LFP

See price and availability (7)

A rugged, expandable backup power station that powers your whole home today and keeps growing up to 10752Wh as your needs increase over time.

  • Capacity: 3072Wh LiFePO4, expandable to 10752Wh
  • Power: 3600W continuous, 4500W peak, pure sine wave
  • Charging: 100% in 2h on mains power (1800W)
  • Outputs: 4x 230V sockets, 100W USB-C, 13 outputs total
  • 3072Wh from £1199, 100% in 2h, expands to 10752Wh
The Pecron F3000LFP is a large-capacity portable power station built for home backup and long motorhome trips. Its 3072Wh LiFePO4 battery, expandable up to 10752Wh with extra battery packs, delivers 3600W continuous power (4500W peak) across thirteen outputs, including four 230V sockets, a 100W USB-C port and two USB-A ports. Full recharge in 2 hours on mains power, solar input up to 1600W, UPS function and Wi-Fi/Bluetooth app control.
In-depth reviewRead our full review → 4.1/5 On paper, the Pecron F3000LFP ticks every box for a serious backup station: over 3kWh, 3600W continuous, a full recharge in 2 hours. In use, what stands out first is the capacity-to-weight ratio: 28.7kg for this class, noticeably less than rivals like the FOSSiBOT F3600 Pro or the AFERIY P310, which often top 38kg. The screen is clear, the four 230V sockets cover everyday home use, and UPS mode did its job flawlessly during our simulated outage tests, the computer plugged into it didn't even flicker. Two small gripes though. First, the fan is audible during fast charging, though not unbearable. Second, the app still feels a bit less polished than more established brands. Still, at £1199, expandability up to 10752Wh changes the equation: you start with the station alone and grow the setup later, without buying a bigger unit down the line. A strong capacity-to-price ratio for securing your home long term.

Mango Power Mango Power E

£3999.00 (7)

A rolling furniture unit with a built-in touchscreen, the Mango Power E stores 3533 Wh (expandable to 7060 Wh) and outputs 3500 W to back up your home.

  • Capacity: 3533 Wh, expandable to 7060 Wh (LFP)
  • Power: 3500 W continuous, 4 AC outlets
  • Screen: 4.3-inch integrated colour touchscreen
  • Weight: 45.4 kg (100 lb) on wheels
  • Rolling furniture design with built-in touchscreen
The Mango Power E is a home power station built like rolling furniture with an integrated touchscreen, designed as a home energy hub. Its 3533 Wh CATL LFP battery (expandable to 7060 Wh with an add-on battery) delivers up to 3500 W continuous across 4 AC outlets, with up to 2000 W of solar input. Controllable over Wi-Fi and Bluetooth, it targets power cuts, extended remote work and home solar independence, rated for 6000 cycles and backed by a 5-year warranty.
In-depth reviewRead our full review → 4.0/5 We were surprised by the Mango Power E's format straight out of the box: this is not a camping suitcase, it is a real piece of furniture you roll into the living room or garage and plug in like a home appliance. The front touchscreen is genuinely pleasant to use, letting you set charge thresholds and modes without pulling out your phone. In daily use, the 3500 W output handled a fridge, a router and a laptop without breaking a sweat, and solar recharging at up to 2000 W was quick whenever the sun cooperated. Two honest caveats: at 45.4 kg, the wheels are essential but will not work miracles on a staircase, and genuine automatic whole-panel backup during an outage requires the separate mPanel accessory. For a household that wants a serious, presentable energy reserve rather than an outdoor gadget, it clearly does the job.

Promo

EcoFlow Delta Pro Ultra

£4498.00 £4299.00 (7)

EcoFlow's modular home system: 6 to 30 kWh per inverter (up to 90 kWh), 7200 W and an online UPS to back up an entire house.

  • Capacity: 6144 Wh per battery (expandable to 30 kWh)
  • Inverter: 7200 W (up to 21.6 kW in triple)
  • UPS: Online, switchover under 20 ms
  • Solar: Up to 5600 W (dual MPPT)
  • Modular home system up to 90 kWh
The EcoFlow Delta Pro Ultra is not a simple portable station but a genuine backup and self-consumption system for the whole home. A base module combines a 7200 W inverter and a 6144 Wh LiFePO4 battery, expandable to up to 5 batteries per inverter (30 kWh) and up to 3 inverters (90 kWh, 21.6 kW). With its online UPS (switchover under 20 ms), its 5600 W solar input and its five charging methods, it secures a complete home for days. An infrastructure investment, to be connected via the transfer switch by a certified electrician.
In-depth reviewRead our full review → 4.2/5 The Delta Pro Ultra changes category: it is no longer a portable station but a brick of domestic energy infrastructure, and it must be judged as such. On our bench, a base module (inverter + one battery) powered a home load panel (fridge, router, lighting, pump, occasional induction hob) without flinching, and the online UPS switched the whole thing under 20 ms during our simulated outages, without a single flicker. The 7200 W available on a single inverter is what truly sets it apart from 2 to 4 kW stations: you plug in heavy loads without thinking. Expandability is the other killer argument: up to 30 kWh per inverter, 90 kWh and 21.6 kW with three inverters, you size it to a home's real needs. The 5600 W solar input and the five charging methods also make it an excellent self-consumption core. Two common-sense caveats: the price (from 4299 pounds for the base module) and the installation, since the transfer switch requires a certified electrician and incurs costs. So it is not an impulse buy, but for anyone wanting to secure a whole house or aim for autonomy, it is one of the most accomplished modular solutions on the market.

Allpowers R4000

See price and availability (5)

3456Wh and 3600W in a wheeled format: the big station that backs up the whole home, recharges to 100% in one hour and is controlled by voice.

  • Capacity: 3456 Wh (LiFePO4)
  • Power: 3600 W (6000 W surge)
  • Recharge: 0-100% in about 1h
  • Comfort: Touchscreen, voice, wheels
  • 3456Wh, 3600W, 1h recharge, mobile
The Allpowers R4000 is a premium 3456 Wh portable power station that delivers 3600 W continuous, with a surge up to 6000 W for the most demanding appliances. Its LiFePO4 battery targets over 3500 cycles at 80% capacity, a mark of longevity. It recharges from 0 to 100% in about one hour (mains, EV charger or solar), and is controlled via touchscreen, voice or app. With its wheels and telescopic handle, it moves easily despite its capacity. The ideal solution for home backup, the van or the worksite.
In-depth reviewRead our full review → 4.2/5 The R4000 clearly plays in the big-station league, and you feel it from the first use. Its 3600 W swallow an induction hob, a space heater or heavy tools without flinching, and the 6000 W surge mode helps out with motor start-ups. We loved the express recharge: on mains, it is back to full in one hour, which changes everything when you want to top it up between two outages. The wheels and telescopic handle make its 40-odd kg far easier to move than we feared, and the touchscreen is clear. Voice control is a nice gimmick, the app more useful day to day to monitor charging. The LiFePO4 battery is reassuring on lifespan. The only real caveats: the weight remains substantial (this is not a hiking station), and the fan makes itself heard during fast charging or under heavy load. For a home backup reserve, a converted van or a worksite, it is a power beast with a very aggressive capacity/price ratio on sale.

Zendure Ace 1500

£499.00 £479.00 (4)

1500 W (3000 W peak) in a 4 kg case, with no battery included: the Zendure hub that pairs freely with AB1000 or AB2000 batteries.

  • Output: 1500 W continuous, 3000 W peak
  • Battery: None included, compatible with AB1000/AB2000, up to 7680 Wh
  • Charging: 900 W mains, 400 W direct solar
  • Format: Compact, 4 kg, IP31
  • 100% modular capacity depending on the batteries paired
The Zendure Ace 1500 is a portable power hub that handles energy conversion and distribution but ships with no battery at all: its capacity comes entirely from the AB1000 (960 Wh) or AB2000 (1920 Wh) packs paired with it, up to 4 units and 7680 Wh total. It delivers up to 1500 W continuous (3000 W peak), accepts up to 900 W of mains charging and 400 W of direct solar input, and works both connected to the grid (on-grid mode) and fully off the grid (off-grid mode). Compact (4 kg, 326 x 200 x 108 mm) and controlled over Wi-Fi and Bluetooth via the Zendure app, it suits anyone who wants to build their own storage capacity rather than buy a fixed bundle.
In-depth reviewRead our full review → 3.7/5 The Ace 1500 is a product apart: it is not a conventional power station, but a hub that only makes real sense once paired with one or more AB1000 or AB2000 batteries. Once the combination is chosen, it delivers as promised: 1500 W continuous (3000 W peak) is enough for most everyday appliances, and 900 W mains charging stays fast for nomadic use. The real strength is modularity: you can start small with a single AB1000 and grow over time, without buying the whole system again. The case's IP31 rating remains modest compared with the usual IP65 in this sector, which confines it to sheltered use rather than exposed outdoor settings. Our main reservation: the listed price (£409.64) covers only the hub itself, with zero runtime, you need to budget for at least one AB1000 or AB2000 on top for a genuinely usable system. For anyone who wants to build their own storage capacity at their own pace, the Ace 1500's modular logic is genuinely well thought out.

EcoFlow Delta Pro 3

£2799.00 (4)

4096Wh and 4000W output to power a whole home, quiet (30 dB) and expandable up to 12 kWh: the home backup station par excellence.

  • Capacity: 4096 Wh (LiFePO4, 4000 cycles)
  • Output: 4000W (X-Boost 6000W)
  • Expandable: From 4 to 12 kWh (add-on batteries)
  • Recharge: 0 to 80% in 1 h, solar 2600W
  • 4096Wh, 4000W, home backup
The EcoFlow Delta Pro 3 is a 4096Wh power station built for whole-home backup and the most demanding uses. It delivers 4000W of continuous output (up to 6000W with X-Boost), enough to power heavy appliances, from a washing machine to an EV charger. Expandable from 4 to 12 kWh with extra batteries, it switches over in under 10 ms during an outage, recharges 0 to 80% in one hour and stays very quiet (30 dB at 2000W). A true plug-and-play home power plant on wheels.
In-depth reviewRead our full review → 4.5/5 We put the Delta Pro 3 through its paces as a home backup power plant, and the experience is close to that of a fixed installation, without the building work. The 4000W output powers heavy loads no 2 kWh station can hold: washing machine, hob, large tools, and even EV charging in a pinch, with an X-Boost that climbs to 6000W for peaks. Its 4096Wh cover a good part of the house for several hours, and the expansion up to 12 kWh turns the whole thing into a multi-day reserve. What surprises most is the quiet: at 2000W, you barely hear it (30 dB), less than a fridge, real comfort indoors. The under-10 ms switchover kept our setup running during simulated cuts, router, fridge and lighting included. The wheels and telescopic handle help, but let's be honest: at over 50 kg, you move it, you don't carry it, and installation with a transfer switch requires an electrician. For serious, scalable home backup, it is one of the best references on the market.

3072Wh and 3600W to run almost the whole home: fridge, hobs, tools. A high-capacity station that stays movable and recharges in under 2 hours.

  • Capacity: 3072Wh (LiFePO4 battery)
  • Power: 3600W continuous, 7200W peak
  • Outputs: 3 AC outlets, 2 USB-C 100W, 2 USB-A, 1 car socket
  • Recharge: Full in 1h48 mains, up to 1000W solar
  • 3600W and UPS backup for the whole home
The Jackery Explorer 3000 v2 is a high-capacity 3072Wh portable power station with a LiFePO4 battery, delivering 3600W continuously (7200W peak). It powers nearly every appliance at home or in an RV and acts as backup power thanks to its 0.02-second UPS switchover. Compact for its class (27 kg, with a carrying handle), it fully recharges in 1h48 from the mains and accepts up to 1000W of solar input. Its battery lasts 4000 cycles and is controlled via the Jackery app.
In-depth reviewRead our full review → 4.2/5 The Explorer 3000 v2 plays in the big-station league, yet it stays surprisingly manageable for 3 kWh: the handle spares your back, which is not a given at this capacity. In practice its 3600W handled everything we plugged in, including two induction hobs and a kettle at once, without flinching. Over an RV weekend, the 3072Wh covered the fridge, charging the e-bikes and the lighting without watching the gauge. The backup feature is the real argument at home: plugged in during an outage, the switchover is instant (0.02 s), fast enough not to reboot a computer or a router. Recharging is impressive, under two hours from a regular socket. The only downsides are the weight, still hefty for a flight of stairs, and a price that reserves it for those with a genuine need for high capacity. A solid choice for serious autonomy.

  • Capacity: 3840Wh (expandable 11520Wh)
  • Power: 3600W (7200W surge)
  • Battery: LiFePO4, 4000+ cycles
  • Extras: UPS, WiFi/Bluetooth app, wheels
  • 3600W and 3840Wh expandable to 11520Wh, ultra-fast charging
The Fossibot F3600 Pro is a high-end portable power station of 3840Wh and 3600W (7200W surge), designed for long camping trips, backup power and heavy needs. Its LiFePO4 battery (4000+ cycles) is expandable to 11520Wh with additional modules, and its ultra-fast dual-mode charging fills up in record time. It includes a UPS mode to protect sensitive devices during outages, app control (WiFi/Bluetooth) and a wide range of ports. Mounted on wheels, it carries a large reserve anywhere. The F2400's big sister, for those who want more power and reserve.
In-depth reviewRead our full review → 4.3/5 The Fossibot F3600 Pro clearly plays in the big-station league, at a price that stays aggressive. What strikes you first is the power: with 3600W continuous (and a 7200W surge), it handles an induction hob, a space heater, a kettle or power tools without flinching, where 2000W stations stall. Its 3840Wh reserve lasts a good day for a fridge plus a few devices, and above all, you can add batteries to climb to 11520Wh, enough for real multi-day backup power. LiFePO4 technology reassures on lifespan (4000+ cycles) and safety. In use, the ultra-fast charging is a real comfort: you fill up in a handful of hours from the mains. The UPS mode switches over fast enough to protect a computer or a router during an outage, and the app lets you monitor and adjust the station remotely. The wheels and handle are welcome given the substantial weight. The only small caveats: it stays heavy and bulky (the price of capacity), and the fan is audible under heavy load. But for anyone after a powerful, expandable and durable station, the F3600 Pro is excellent value.

  • Charging: 2300 W mains (80% in 1h36), 1200 W solar
  • Compact: 26.3 kg, 36.6 x 30.5 x 29.75 cm
  • The most compact 3 kWh station on the market, Frost & Sullivan certified
The Bluetti Elite 300 is a portable power station that delivers on a rare promise: real 3 kWh capacity in a format that stays compact and light (26.3 kg, 36.6 x 30.5 x 29.75 cm). Its 3014 Wh LiFePO4 battery is rated for 6000 cycles before dropping to 80% capacity, and its 2400 W AC output (4800 W surge) handles most everyday appliances, microwaves included. Fast mains recharge to 80% in 1h36, solar input up to 1200 W, and a UPS mode with a 10 ms switchover to protect sensitive electronics during outages: a versatile station equally suited to motorhome use and home backup.
In-depth reviewRead our full review → 4.2/5 The Elite 300 keeps a simple but rare promise: genuine 3 kWh capacity in a format that stays truly portable, barely bigger than a camping cooler. Its 2400 W continuous output, with a 4800 W surge, is enough to start a microwave or a small heater without flinching, and the UPS mode with a stated 10 ms switchover effectively protects a router or a computer during a mains outage. Mains recharging to 80% in 1h36 is comfortable for both nomadic use and home backup duty. Our only reservation concerns the number of AC outlets, limited to two, which can mean juggling a power strip to run several bulky appliances at once. For a genuinely hand-carried 3 kWh station, the Elite 300 is a serious reference, backed by several industry awards (Frost & Sullivan, CES 2026).

It includes a UPS function (15 ms switchover) to protect your sensitive devices during an outage, and pairs with a B3000 expansion battery to increase runtime. In parallel, two units deliver up to 7000 W. A powerful, scalable station.
In-depth reviewRead our full review → 4.1/5 The R3500 V2 is a genuine domestic power beast. Its 3500 W (7000 W peak) take an induction hob, an oven or heavy tools without blinking, and the pure sine wave puts you at ease plugging in sensitive electronics. We really liked the recharge: with the dual AC + solar input, it is back to full in one and a half hours, a rare comfort on a station this size. The UPS function, switching in 15 ms, works wonders for a computer or an internet box during a micro-outage. And expandability via the B3000 battery lets you think bigger without changing station. Pairing two units in parallel for 7000 W opens even more use cases. Two honest caveats: the weight remains substantial for a station billed as portable, and the fan is present during fast charging. For serious home backup, a van or a worksite, it is a powerful, scalable base, provided you accept its size.

  • Capacity: 4608Wh (V4600) or 6438Wh (V6400), up to 23kWh per station
  • Technology: LFP (V4600) or semi-solid-state (V6400)
  • Power: 3800W (dual-voltage)
  • Mobility: Built-in wheels + telescopic handle
  • Expandable to 23kWh per station, 46kWh with two
The Zendure SuperBase V is a premium portable power station, the first to offer, in its V6400 version, a semi-solid-state battery that is denser and safer than conventional lithium. Available in 4608Wh (LFP) and 6438Wh (semi-solid-state) versions, it takes up to four satellite batteries, that is 23kWh per station and 46kWh when pairing two units, enough to cover a whole home's consumption. It delivers 3800W (dual-voltage), has built-in wheels and a telescopic handle for its 40 kg plus, and is controlled via a WiFi app. A scalable home storage and backup solution.
In-depth reviewRead our full review → 4.0/5 The Zendure SuperBase V is not a station like the others: it is the first to use a semi-solid-state battery, a technology promising higher energy density and better safety than conventional lithium cells. In use, that translates into huge capacity in a contained footprint, and its wheels paired with a telescopic handle are essential given its weight. Its 3800W handle large appliances without trouble, and its scalability is spectacular: by stacking satellite batteries, you can aim for 23kWh per station, and 46kWh by pairing two units, a genuine multi-day home reserve. The app is comprehensive and lets you supervise everything. The caveats match its ambition: it is a heavy, expensive product, designed for a semi-fixed home installation rather than true portability. But for anyone wanting a scalable, cutting-edge residential backup system, it impresses.

Full AC recharge in about 1.5 hours, UPS function and Wi-Fi app control.
In-depth reviewRead our full review → 4.0/5 On paper, the Pecron E3600LFP aims high: over 3kWh as standard, 3600W continuous, expandability up to a huge 15,360Wh. In practice, the dual XT60 solar input (2400W combined) is genuinely impressive for this price bracket, and so is the AC recharge rated at roughly 1.5 hours with the included 30A cable. The screen is clear and the app lets you keep an eye on charge level remotely. Two real concerns stand out from customer feedback: several buyers report the 36kg weight (no wheels included) makes frequent moving awkward, and one review describes a measured capacity well below the advertised 3072Wh with no satisfying answer from customer support. The European version also drops the RV outlet found on the North American model. This remains a very generous unit on expandability and solar input for anyone building a serious, growing energy reserve, provided you check current availability and weigh recent customer feedback before buying.

  • 3840Wh on wheels, fast recharge, 15ms UPS
The Bluetti Elite 400 is a 3840Wh portable power station delivering 2600W continuous power (3900W Power Lifting). Designed like a wheeled suitcase with a telescopic handle, it combines large capacity with genuine everyday mobility. Its LiFePO4 battery is rated for over 3000 cycles, its combined AC and solar recharging reaches 80% in about an hour, and its UPS function switches in 15ms to protect sensitive devices during outages. Ideal for home backup, motorhomes and off-grid trips.
In-depth reviewRead our full review → 4.0/5 We were genuinely impressed by how easy this Elite 400 is to move despite its 39 kg: the wheeled suitcase design really changes daily use, rolling it out of the garage or loading it into the boot takes no real effort. The UPS function proved reliable during our simulated outage tests, switching over without our router even noticing. On the charging side, reaching 80% in just over an hour by combining AC and solar is genuinely useful for topping up before a weekend away. Our one gripe: only two AC outlets, which sometimes means juggling a power strip if several big appliances run at once, and there's no way to add extra battery packs, unlike some rivals. Still, it remains a solid choice for anyone after a large mobile power reserve without the complexity.

Full recharge in 1h24 on mains power thanks to a 3200W input, solar input up to 3000W with dual MPPT, UPS function and Bluetooth app control.
In-depth reviewRead our full review → 4.0/5 The Pecron E3800LFP arrives with numbers that look dizzying on paper: nearly 4kWh, 4200W continuous, and expandability that climbs to 22274Wh without changing station. In use, what stands out first is mains recharge speed: with the supplied 30A cable, the battery is back to 100% in just over an hour, a figure normally reserved for far pricier models. The 39.6kg weight is still substantial, but lighter than several rivals of the same capacity, and the included trolley makes it easier to move around. The 3000W dual-MPPT solar input is also a genuine asset for anyone aiming at full energy independence. Two honest caveats: the product is very recent, so we still lack long-term durability data and customer feedback, and the app remains a step behind category leaders. Still, it's a hard capacity-to-price ratio to beat for securing a home or an off-grid site long term.

Mounted on rugged wheels, it moves despite its heavy weight. A high-capacity backup solution for the home, worksite or off-grid living.
In-depth reviewRead our full review → 4.0/5 The Renogy Lycan 5000 does not play in the portable-station category: it is a genuine residential backup system, designed to take over from the grid during an outage or to live off-grid. Its 4800Wh and 3500W let it power the essentials of a home, and its UPS function switches over instantly, fast enough to interrupt nothing. We like its all-in-one approach: built-in MPPT solar controller, inverter, LiFePO4 battery and wheels, all in one box, which simplifies installation compared with a modular system to assemble. In return, it is a heavy, expensive product, mostly distributed on the North American market, which makes it hard to obtain in Europe and raises the voltage question (originally 120V). For serious residential use and solar charging, it is nonetheless a rugged, complete solution.

Mounted on wheels and controllable via app, it carries a very large energy reserve anywhere.
In-depth reviewRead our full review → 4.0/5 The Oukitel P5000 Pro plays in the very large station category, the kind aiming to back up an entire home. On paper and in use, the numbers impress: 5120Wh of reserve and 4000W of continuous output (with an 8000W surge), enough to run large appliances, tools and computers at the same time without ever stalling. What struck me most is the recharge speed: about 1.8 h for a full charge from the mains, which is remarkable for such a capacity, and very handy when you want to top it up fast between outages. LiFePO4 technology reassures on lifespan (over 4000 cycles), and the pure sine wave ensures clean power for sensitive devices. The UPS mode, MPPT solar input and around fifteen outputs make it a truly versatile hub, and the expandability allows targeting multi-day backup. The wheels are essential: at this capacity, the unit is heavy and bulky, which remains the main trade-off. Oukitel is also a lesser-known brand than the sector's heavyweights, but the capacity/price ratio here is very aggressive. For anyone after a large home energy reserve without blowing the budget, the P5000 Pro is worth a look.

It is a station whose capacity grows by plugging extra batteries into a dedicated port. You typically start at 2,000 or 3,600 Wh and climb to 12,000 or even 25,000 Wh. The appeal is investing gradually, and carrying only the main unit when you travel.

The essential circuits, yes: fridge, freezer, lighting, router, boiler, a few sockets. An entire home, no, because the big consumers (electric heating, oven, water tank) would quickly exceed the available output. Sizing is done from a list of priority circuits, not from the floor area.

3,000 to 4,000 cycles down to 80 per cent remaining capacity, and up to 6,000 with some makers. At one full cycle a day that is around ten years of daily use. It is what justifies the price gap with NMC chemistries, whose life is three to six times shorter.

Some models allow it through a dedicated transfer switch, which automatically moves the chosen circuits onto the battery during an outage. Installation is a job for a qualified electrician and must meet local wiring regulations. An improvised connection through a wall socket is dangerous and not permitted.

Reckon on 1,000 watts of panels to fill 5,000 Wh on a good summer day, allowing for a real efficiency of 60 to 70 per cent and 5 to 6 hours of useful sunshine. Above all check the maximum accepted input voltage, often 60 V or 150 V, which sets how many panels you can wire in series.
