Detailed overview: Fossibot F1800 portable power station 1024Wh
The Fossibot F1800 is a portable power station that fills the gap between the Fossibot F1200 and F2400 ranges: it has exactly the same 1024Wh capacity as the F1200, but a noticeably higher output of 1800W continuous (2700W peak for 400ms), enough to start a power tool or an induction hob. Its LiFePO4 battery is rated for more than 4000 cycles to 80% capacity and comes with a 5-year manufacturer warranty, twice as long as its F1200 and F2400 cousins.
On charging, it goes from 0 to 80% in 45 minutes on mains power thanks to an adjustable input up to 1200W, and reaches 100% in about 68 minutes. It also accepts solar charging (up to 500W, 12-60V) for a full charge in about 2 hours in good sunlight, and car charging through the cigarette lighter port. A rare feature at this price point: it accepts a capacity extension via an external lead-acid or lithium battery (12, 24 or 48V, 15A max, cable not included), for anyone who wants to go beyond the standard 1024Wh.
It also stands out from the F1200 through its connectivity: a dedicated WiFi and Bluetooth app lets you monitor charging in real time, set the mains charging power (400W, 800W or 1200W) and turn on ECO mode, which limits standby consumption to save up to £110 a year on the electricity bill. On the output side, it offers 3 pure sine wave 230V AC outlets, two 140W USB-C ports (fast enough to charge a laptop very quickly), two 18W USB-A ports and a 12V/10A cigarette lighter output (120W). Its UPS function switches to battery power in under 10ms in the event of an outage, fast enough to protect a computer or a sensitive medical device.
At 11.25kg for 371 x 206 x 258mm, it stays lighter than the F2400 (22kg) while offering 600W more power than the F1200. It runs quietly, under 35dB during mains charging at 600W, and its multi-sensor BMS protects the battery against overheating, extreme cold, overcharging and short circuits.
In short, the Fossibot F1800 occupies a precise spot in the range: the same energy reserve as the F1200, but with the power, app and warranty of a higher-end model, without reaching the F2400's price or weight. A relevant compromise for anyone who needs to run hungrier appliances without changing format.

What is this power station best for?

Home & Power cuts Ideal
With 1024Wh and 1800W continuous output (2700W peak), the Fossibot F1800 covers the essentials of a home during a power cut, with a much bigger power margin than the F1200 for hungrier appliances (induction hob, microwave, power tools). Its UPS function switches to battery in under 10ms, fast enough not to interrupt a computer, a router or a medical device such as a CPAP machine. The WiFi/Bluetooth app lets you monitor charging remotely and turn on ECO mode, which limits standby consumption to save up to £110 a year. A full recharge in about 68 minutes on mains power lets you top up quickly between outages, and its 5-year warranty, twice as long as the F1200's, is reassuring for long-term reliability. It even accepts a capacity extension via an external battery for households that want to go beyond the standard 1024Wh. An excellent home backup choice, more versatile than the F1200 for a modest extra cost.
-
Motorhome & Van life Suitable
In a motorhome or van, the Fossibot F1800 brings the same 1024Wh reserve as the F1200, but with 1800W continuous output that handles an induction hob or a small heater without flinching. Its 0-80% recharge in 45 minutes lets you top up quickly at a service stop, and its solar input up to 500W extends autonomy on the road. Controlled from a WiFi/Bluetooth app, it shows charge status in real time. At 11.25kg, it stays lighter than the F2400 while offering more power than the F1200.
-
Camping & Tent Suitable
For a camping weekend, the Fossibot F1800 powers an electric cooler, campsite lighting and charges several devices at once thanks to its 3 AC outlets and 2 USB-C 140W ports. Its fast recharge (0-80% in 45 minutes) lets you top up before leaving, and its solar input up to 500W extends autonomy in good weather. Its quiet operation, under 35dB, will not disturb the campsite, and the mobile app lets you monitor charging remotely from the tent.
-
Remote work Suitable
For working in the garden, on a balcony or during a power cut, the Fossibot F1800 effortlessly powers a laptop through its 140W USB-C ports, one or two monitors and a router thanks to its 1800W pure sine wave output. Its UPS function switches over in under 10ms, fast enough not to lose a work session during a brief outage. ECO mode, controlled from the app, reduces standby consumption for extended use, and its 1024Wh cover a good part of a remote working day.
-
Off-grid & Solar Suitable
Solar compatible up to 500W (12-60V), the Fossibot F1800 can power a garden shed or an occasional workshop off-grid. Unlike the F1200, it accepts a capacity extension via an external lead-acid or lithium battery (12, 24 or 48V), to go beyond the standard 1024Wh as needs grow. Its solar input remains more modest than stations built for full-time off-grid living, and the extension requires wiring and a battery that are not included. A solid option for a scalable seasonal setup.

Comparison
Where does the Fossibot F1800 sit against its two siblings already in the catalogue, the F1200 and the F2400, as well as against an external competitor of comparable power such as the Anker Solix C1000? The F1800 has exactly the same capacity as the F1200 (1024Wh) but 50% more output power (1800W versus 1200W), while the F2400 doubles the capacity at the cost of nearly double the weight.
| Criterion | Fossibot F1800 | Fossibot F1200 | Fossibot F2400 | Anker Solix C1000 |
|---|---|---|---|---|
| Capacity | 1024Wh | 1024Wh | 2048Wh | ≈ 1056Wh (expandable to 2112Wh) |
| Continuous / peak power | 1800W / 2700W | 1200W / 2400W | 2400W / 4800W | 1800W / 3000W |
| App / Bluetooth | Yes (WiFi + Bluetooth) | None (LCD screen) | None (LCD screen) | Yes |
| AC outlets | 3 | 2 | 3 | 2 |
| Weight | 11.25kg | 11.5kg | 22kg | ≈ 13.3kg |
| Warranty | 5 years | 2 years | 2 years | ≈ 5 years |
| Observed price | ≈ £471 | ≈ £359-376 | ≈ £680 | ≈ £683 |
The Fossibot F1800 occupies a very precise spot in the manufacturer's range: at exactly the same capacity as the F1200, it brings 50% more power, a WiFi/Bluetooth app and twice the warranty, for a modest price premium. Against the F2400, it stays much lighter and cheaper, at the cost of half the capacity. Compared with the Anker Solix C1000, it offers comparable power and warranty at a noticeably lower price, without the Anker's proprietary expandable capacity system (though it offers its own extension via an external battery, wired by the user). For anyone who needs more power than the F1200 without the weight of the F2400, the F1800 is the most sensible choice in the Fossibot range.

Our tester's review: Christophe Delpuech
We ran the Fossibot F1800 for several weeks, between the garden, a van trip and a simulated power cut. First impression when unboxing it next to our F1200: same footprint, but 600W more power, more than enough to start our kettle and induction hob without a hitch. The WiFi/Bluetooth app is a real step up from the F1200: we could monitor charging from the sofa, and ECO mode visibly cut our standby draw. The 45-minute recharge to 80% on mains power holds up, and UPS mode took over without a single hiccup during a simulated outage on our router. The only downside: the fan gets a bit noisy under heavy load, and the external battery extension requires wiring your own cable. For a station that keeps the F1200's compact footprint while gaining power, connectivity and a longer warranty (5 years), it is an upgrade that makes sense.
Frequently asked questions: Fossibot F1800 portable power station 1024Wh
