Detailed overview: Fossibot F2400 portable power station 2048Wh
The Fossibot F2400 is a portable power station that made a name for itself by undercutting the 2 kWh category without sacrificing essential features. It is built around a 2048Wh LiFePO4 battery and a pure sine wave inverter of 2400W continuous (4800W peak), enough to run the vast majority of household appliances: fridge, kettle, coffee maker, microwave, worksite tools, TV.
Its main argument is power-to-price: it offers specs worthy of the market benchmarks at a noticeably lower price. It includes a UPS backup function that switches to battery in under 10 ms during an outage, fast enough to protect a computer, a router or a sensitive device. Charging is fast: up to 1100W AC input allows a full charge in about 2 hours, or 1h30 when combining mains with 500 W of solar, and it also accepts solar and car charging.
On connectivity, it is very complete with 13 ports: 3 AC outlets, a 100W USB-C port (ideal for a laptop), several USB-A ports, a 12V car socket and DC outputs. It has, however, no app, no Bluetooth and no Wi-Fi: everything is read on the screen and set from the front panel, including charging power, adjustable with a dial. Its LiFePO4 battery is rated for 3500 cycles, a lifespan that can exceed 10 years.
Its limits are mainly about brand awareness: Fossibot is less established than Jackery, EcoFlow or Bluetti, which can mean a less extensive after-sales network and accessory range. Technically, though, the F2400 has nothing to be ashamed of and is one of the best deals on the market for anyone looking for a powerful, complete and affordable 2 kWh station.

What is this power station best for?
-
Home & Power cuts Ideal
With 2048 Wh and 2400 W, the Fossibot F2400 secures a large part of a home during an outage, at one of the most aggressive capacity-to-price ratios on the market: fridge, freezer, router, lighting and small appliances run for many hours, and its UPS function switches over in just 8 ms, an imperceptible delay that protects sensitive devices. Its 4800 W peak absorbs the startup surges of large appliances, and its fast full recharge (about 2 h) tops it up quickly. Its solar input up to 500 W makes it a sun-rechargeable reserve. LiFePO4 chemistry (4000 cycles) ensures good longevity. An excellent choice to secure a home without breaking the budget.
-
Job site & Tools Ideal
On an off-grid site, the Fossibot F2400 offers an economical, muscular power source: its 2400 W (4800 W peak) start and run a saw, grinder, sander or compressor, and its three outlets feed several stations. Its 2048 Wh cover a workday, and its fast full recharge (about 2 h) tops it up between tasks, without the noise or fumes of a generator. The pure sine wave protects the machines’ electronics, and a solar input up to 500 W supplements autonomy on site in good weather. At 21.5 kg it moves from point to point. Very good power-to-price for a tradesperson kitting out a mobile site.
-
Motorhome & Van life Suitable
Its 2048 Wh offer nice autonomy in a motorhome: fridge, lighting, ventilation, device charging and light cooking run for several days, and its 2400 W occasionally accept a hungrier appliance. Its fast full recharge (about 2 h) tops up at a service area during a break, and a solar input up to 500 W extends autonomy in good weather. Its attractive capacity-to-price ratio makes it an interesting option to equip a vehicle without a big budget. At 21.5 kg, it suits motorhomes and vans with a dedicated bay rather than the most compact vans.
-
Off-grid & Solar Suitable
Solar-compatible, the Fossibot F2400 serves as a 2048 Wh reserve to distribute for a cabin, workshop or off-grid plot, at an accessible price: its 2400 W power a fridge, pump, tools and lighting, and its solar input up to 500 W refills part of its charge in good weather. LiFePO4 chemistry (4000 cycles) withstands daily cycling for years. For permanent high-production self-consumption, note that its solar input stays moderate compared with premium stations: it suits seasonal or backup use above all, where its excellent capacity-to-price ratio makes the difference.
-
Events & Market stalls Suitable
A large reserve and quiet operation, the Fossibot F2400 cleanly powers a market, a stand or an outdoor event without the noise or smells of a fuel generator: its 2400 W handle a PA system, lighting, a payment terminal and small catering gear, and its 2048 Wh cover a long day. Its fast full recharge (about 2 h) refills between highlights, and a solar input up to 500 W supplements autonomy at long events. Its accessible price makes it an interesting solution for associations and small organisers who want a reliable alternative to a generator without a big investment.

Comparison
How does the Fossibot F2400 compare with benchmark 2 kWh stations?
| Criterion | Fossibot F2400 | EcoFlow Delta 2 Max | Bluetti AC200L |
|---|---|---|---|
| Capacity | 2048Wh | 2048Wh | 2048Wh |
| Power | 2400W | 2400W | 2400W |
| UPS | Yes (< 10 ms) | Yes | Yes |
| Indicative price | About £598 | About £811 | About £1282 |
At near-identical specs (2048Wh, 2400W, UPS), the Fossibot F2400 stands out for a price far below the EcoFlow Delta 2 Max and the Bluetti AC200L. The trade-off is a lesser-known brand, with less developed support and accessories. On a tight budget, it is the most rational option.

Our tester's review: Christophe Delpuech
The Fossibot F2400 is the value surprise in the 2 kWh category. On paper and in use, it rivals far more expensive stations: its 2400W ran a fridge, a kettle and tools without flinching, and its 2048Wh cover solid autonomy. We especially liked the UPS function, which switches over in under 10 ms during an outage, fast enough not to reboot a computer, along with the full recharge in two hours. Connectivity is generous with 13 ports, including a real 100W USB-C and a 25 A 12 V output its direct rivals do not offer. The downsides are typical of a lesser-known brand: after-sales support and accessory availability are less developed than with the leaders, and the green look will not please everyone. But for the budget, it is one of the best deals around.
Frequently asked questions: Fossibot F2400 portable power station 2048Wh
With 2400W continuous and 2048Wh, it powers a fridge, a kettle, a coffee maker, a microwave, tools or a TV. It can run several appliances at once and serves as backup power.
Yes. During an outage, it switches to battery in under 10 ms, fast enough not to interrupt a computer, an internet router or a sensitive device. It is a real asset at home.
About 2 hours for a full charge from the mains, thanks to an input of up to 1100W. The 1h30 sometimes quoted assumes adding 500 W of solar. It also accepts solar and car charging for off-grid use.
Its LiFePO4 battery is rated for 3500 cycles and its inverter is pure sine wave, signs of seriousness. The main caveat is the after-sales network and accessory availability, less developed than with the leaders.
