Detailed overview: Aferiy P040 400W Power Station
The Aferiy P040 is a compact portable power station built to slip a reliable energy reserve into a bag, a car or a backup drawer. With its 256Wh LiFePO4 battery and 400W pure sine wave output, it covers everyday nomadic needs: charging smartphones, a tablet, a laptop, LED lighting, a small fan or a camera.
Charging is one of its strong points: up to 300W on the mains for a full charge in just 1 hour 12 minutes, a rare speed at this price point. It also accepts up to 120W of solar input through a DC5521 connector (an MC4-to-DC5521 cable is included), and recharges from a car's 12V socket at up to 8A. On the output side, it offers one AC outlet, one USB-A Quick Charge 3.0 port (18W), two USB-C Power Delivery ports (20W and 100W, the latter enough for a laptop) and a 12V/10A car-style DC outlet, five outputs in total.
The Aferiy P040 includes a UPS (uninterruptible power supply) function that switches to battery in under 10 milliseconds during a mains power cut, one of the fastest switchover times on the market for such a compact unit. It can therefore protect a computer, a home router or a small server from micro power cuts. A battery management system (BMS) with six-layer protection (overvoltage, over-discharge, overcurrent, overheating, low temperature, short circuit) keeps everything safe, and an LCD screen shows the charge level and power draw in real time.
Its LiFePO4 battery is rated for 3500 cycles before dropping to 80% of its original capacity, a sign of durability. The manufacturer backs it up with a base 2-year warranty, extendable for free up to 7 years by registering the product on its website, a rare argument at this price level. At 4kg and 259 x 174 x 201mm, it stays easy to carry, even though its 400W output limits it to smaller devices: no kettle or hotplate here, but a genuine companion for camping, remote work on the move, or the odd power cut at home.

Rough estimate: real consumption varies, and very power-hungry appliances (heating elements) must stay below the output power.
What is this power station best for?

Camping & Tent Ideal
At 4kg with a built-in handle, the Aferiy P040 slips easily into a bag or a car boot for a camping weekend. Its 256Wh cover LED lighting, charging several smartphones, a tablet, a camera and a small fan for an evening or a full night. Its 100W USB-C port charges a laptop at full speed, handy for extending a trip without heading back to a mains socket. For charging, it accepts up to 120W of solar power through its DC5521 connector (MC4 cable included), enough to top up at camp in good weather in around two and a half hours. Its LiFePO4 battery, rated for 3500 cycles, holds up season after season, and its LCD screen lets you check the remaining charge at a glance. One limit to keep in mind: its 400W isn't enough for a big electric appliance (kettle, hotplate), but for lighting, electronics and light camp comfort, it's a compact, well thought out reserve of power.
-
Remote work Suitable
For a session of remote work, the Aferiy P040 reassures as much as it powers: its UPS function switches to battery in under 10 milliseconds during a mains cut, enough to protect a laptop and a home router without losing an ongoing session. Its 100W USB-C port charges a laptop at full speed, and its 256Wh provide several hours of runtime for a light setup. It slips easily into a bag between a coffee shop and a coworking space. Without Bluetooth or an app, monitoring stays basic, through the built-in LCD screen only.
-
Road trip & Car Suitable
On a road trip, the Aferiy P040 stays out of the way: at 4kg, it fits in the boot or under a seat and charges cameras, a drone, a laptop and phones between stops thanks to its five outputs. Charging from the car's 12V/8A socket tops it up on the move without draining the vehicle's battery, and its solar input of up to 120W extends runtime on long days. Its ultra fast mains recharge (1h12) means it's ready to go again after a short stop. Its 256Wh do limit it to light devices over several days in a row.
-
Photo & Video Suitable
On a photo shoot, the Aferiy P040 makes a handy backup power source: its 256Wh recharge several camera batteries, a drone and flash batteries between sequences, and its 100W USB-C port tops up a laptop quickly for editing on the go. Its 1h12 mains recharge allows a full top-up between sessions. At 4kg, it slips into a camera bag without weighing it down too much. Its 400W output suits a small LED light as backup lighting, but stays limited for hungrier fixtures.
-
Health & CPAP Suitable
For a CPAP machine on the move, the Aferiy P040 offers a genuine safety net: its 256Wh generally cover one night of treatment without a heated humidifier, and its UPS function switches to battery in under 10ms during a power cut, without a jarring wake up. Its LCD screen lets you check the charge level before bed. Light at 4kg, it travels easily. Check your machine's actual power draw before you leave: with heated humidification switched on, runtime will be noticeably shorter than a single night.
-
Home & Power cuts Backup only
As a backup during a power cut, the Aferiy P040 kicks in almost instantly thanks to its UPS function (under 10ms): it keeps a home router, lighting and small electronics running. Its 256Wh and 400W limit it to essential devices and short outages, not an extended backup for several rooms.

Comparison
Under £200, the Aferiy P040 goes up against compact power stations in the 250 to 290Wh range, often compared in searches like "Aferiy P040 vs EcoFlow River 3" or "Aferiy P040 vs Bluetti EB3A". Here is how it stacks up against three alternatives: the EcoFlow River 3, the fastest to recharge in its class, the Bluetti EB3A, more powerful, and the Jackery Explorer 300 Plus, one of the lightest.
| Criterion | Aferiy P040 | EcoFlow River 3 | Bluetti EB3A | Jackery Explorer 300 Plus |
|---|---|---|---|---|
| Capacity | 256Wh | 245Wh | 268Wh | 288Wh |
| Continuous power | 400W | 300W (600W X-Boost) | 600W (1200W peak) | 300W (600W peak) |
| Mains recharge 0-100% | 1h12 | ≈ 1h | ≈ 1h30 | ≈ 2h |
| Warranty | up to 7 years (2 + 5) | 5 years | 2 years | 5 years |
| Weight | 4kg | 3.5kg | ≈ 4.6kg | ≈ 3.75kg |
| Observed price | ≈ £190 | ≈ £230 | ≈ £220 | ≈ £250 |
In short, the Aferiy P040 stands out for its price and its warranty extendable to 7 years, well beyond the rest of the market in this segment. The Bluetti EB3A wins on raw power (600W continuous), useful for bigger appliances, and the EcoFlow River 3 remains slightly faster to recharge. For an affordable first purchase backed by a genuine warranty safety net, the Aferiy P040 remains the most reassuring option.

Our tester's review: Christophe Delpuech
We tested the Aferiy P040 as a backup power source at the office and during a camping weekend, and its charging speed stood out immediately: a full charge in just over an hour, handy when you're packing at the last minute. In the field, its two USB-C ports (one rated at 100W) charged a laptop and a smartphone at the same time without breaking a sweat, and the AC outlet was enough for a small lamp and a camera charger during a weekend under canvas. At home, its UPS function kicked in within a fraction of a second during a test power cut, without our router so much as blinking. Two honest downsides: 400W isn't enough for anything power hungry (forget the kettle), and the total lack of Bluetooth or an app limits remote monitoring. Still, at this price, backed by a warranty extendable to 7 years, it's a small power bank that's hard to catch out.
