Detailed overview: Allpowers R3500 V2 2880Wh portable power station
The Allpowers R3500 V2 is a high-capacity portable power station (2880 Wh) built for demanding use: home backup, converted van, worksite or outdoor event. It targets those who want a powerful, scalable reserve, able to replace a generator with no noise or fuel.
Its pure sine wave inverter delivers 3500 W continuous, with a 7000 W peak to absorb start-up surges. Enough to simultaneously power nearly all of a home's devices: fridge, induction hob, oven, washing machine, tools. Pairing two units in parallel raises the power up to 7000 W (12 kW peak).
Its battery uses LiFePO4 chemistry, known for safety and longevity, with over 3500 charge cycles stated. Recharging is a strong point: thanks to the dual AC + solar input up to 4000 W, it reaches 100% in about one hour, and accepts up to 2000 W of solar (full recharge in 2.5 h in the sun). Four charging modes are available (mains, solar, car, generator, or dual AC + solar).
It includes a UPS function (backup inverter) that switches to battery in just 15 ms during an outage, protecting your sensitive devices (computer, internet box, light medical equipment). Its capacity is expandable with a B3000 expansion battery, to tailor runtime to your needs.
Powerful, quick to recharge and scalable, the Allpowers R3500 V2 is an excellent base for reliable home backup or high-capacity off-grid power, provided you accept its substantial weight.

What is this power station best for?

Home & Power cuts Ideal
With 2880 Wh, 3500 W of output and a UPS function (15 ms switchover), the Allpowers R3500 V2 aims to be a true home backup: when the grid drops it instantly takes over the freezer, fridge, router, lighting and even a hob or a pump, with no perceptible interruption. Its 2880 Wh carry a home’s essentials for several hours, and its expandable capacity lets you target a full day of backup on critical loads. The 3500 W continuous (7000 W peak) easily absorb high-inrush appliances. Recharging from 0 to 100 % in one hour (mains plus solar up to 4000 W) brings it back online quickly after use. A LiFePO4 battery and 5-year warranty round out a reassuring profile for recurring or extended outages.
-
Job site & Tools Ideal
The Allpowers R3500 V2 is built for the demanding job site: its 3500 W continuous, peaking at 7000 W, start and run the hungriest tools, an angle grinder, circular saw, compressor or jackhammer, where more modest stations stall. Its four 230 V outlets feed several stations at once, and the pure sine wave protects the machines’ electronics. The 2880 Wh provide hours of sustained use, and capacity expansion stretches the day with no generator and no noise. A full recharge in one hour (up to 4000 W mains plus solar) keeps pace with professional work. A durable LiFePO4 battery and 5-year warranty make it a reliable work tool, from structural work to renovation.
-
Off-grid & Solar Ideal
Thanks to its expandable capacity and generous solar input (up to 1300 W across two MPPT controllers), the Allpowers R3500 V2 forms a genuine off-grid home storage core: it recharges fast in the sun and delivers up to 3500 W, enough to power a cabin, workshop or tiny house in real comfort, fridge, pump, tools and appliances included. Its 2880 Wh base, expandable, lets you size the reserve to sunlight and needs. The LiFePO4 chemistry sustains daily cycling over many years. For permanent year-round self-consumption, pair several panels and possibly an extra battery; for seasonal or backup use, it stands well on its own and replaces a generator, silently.
-
Motorhome & Van life Suitable
In a large motorhome or a well-equipped van, the Allpowers R3500 V2’s 2880 Wh provide ample autonomy to live several days with complete peace of mind: fridge, electric cooking, a booster water heater, occasional air conditioning and charging of all electronics. Its 3500 W allow the hungriest appliances without compromise, and solar input up to 1300 W refills quickly while driving or at a stop. The expandable capacity lets you tailor the reserve to residential use of the vehicle. Its size and weight, however, suit a fixed spot and a spacious vehicle rather than a small, light van.
-
Events & Market stalls Suitable
For an outdoor event, a wedding, market, community concert or film shoot, the Allpowers R3500 V2 is a strong alternative to a generator: its 3500 W power a PA system, stage lighting, a catering stand or camera gear, all in complete silence and with no fumes or petrol smell. Its 2880 Wh, expandable, cover several hours of activity, and fast recharging (up to 4000 W mains plus solar) allows a top-up between highlights. The four 230 V sockets and many USB ports easily share power among participants. For a very long continuous full-load day, plan for capacity expansion or a solar top-up.

Comparison
At around £1967 to £2736, the Allpowers R3500 V2 compares with powerful portable power stations of 2500 to 3500 Wh, targeted by searches such as "3500W power station" or "powerful expandable portable battery". Here is how it sits against three references: the EcoFlow Delta Pro 3, the Bluetti AC200L and the Allpowers R4000.
| Criterion | Allpowers R3500 V2 | EcoFlow Delta Pro 3 | Bluetti AC200L | Allpowers R4000 |
|---|---|---|---|---|
| Capacity | 2880 Wh | 4096 Wh | 2048 Wh | 3456 Wh |
| Power | 3500 W (7000 W) | 4000 W (5600 W) | 2400 W (3600 W) | 3600 W (6000 W) |
| Recharge 0-100% | ≈ 1 h | ≈ 1 h | ≈ 1.5 h | ≈ 1 h |
| UPS function | Yes (15 ms) | Yes | Yes | Yes |
| Observed price | ≈ £1966 | ≈ £2735 | ≈ £1025 | ≈ £1624 |
In short, the Allpowers R3500 V2 stands out for its high power (3500 W, 7000 W peak), its one-hour recharge and its very responsive UPS function. The Delta Pro 3 offers more capacity but costs more, the AC200L plays compactness, and the R4000, from the same maker, offers more capacity for a close price on sale. For a powerful, scalable station, the R3500 V2 is a solid choice.

Our tester's review: Christophe Delpuech
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 hour, 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.
