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.
Comparison
At around 2300 to 3200€, 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 | ≈ 2299 € | ≈ 3199 € | ≈ 1199 € | ≈ 1899 € |
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.
