FOSSiBOT, 1,500 to 2,599 Wh
2,048Wh
A refrigerator, router and lights through a day without power; RV weekends.
Strengths
- 2,400 W continuous and a 4,800 W surge rating, above the 2,645 W start-up of a 1/2 HP sump pump; it runs that pump for 1.8 hours.
- Six AC outlets, tied with the Anker SOLIX C2000 Gen 2 for the most in the 2 kWh class here.
- UPS switchover under 8 ms, the fastest rating on this site.
- Runs a 25 cu ft French-door refrigerator for 19 hours or an eero 6+ Wi-Fi router for 3.1 days.
- Four USB-C ports (one 100 W, three 20 W) and two 18 W USB-A ports.
Limits
- In UPS mode, FOSSiBOT's manual limits the US unit to 1,100 W of AC load, well below its 2,400 W rating.
- Slower recharge: about 2 hours to full at 1,100 W from the wall, against 1.4 hours for the BLUETTI Elite 200 V2 at 1,800 W in Turbo mode. Solar input is 500 W, half the Elite 200 V2's 1,000 W.
- Not expandable, per FOSSiBOT's FAQ, and 48.5 lb; the Anker SOLIX C2000 Gen 2 weighs 41.7 lb and expands to 4,096 Wh.
- The 5-year warranty (2 years plus a 3-year extension) applies to orders from us.fossibot.com only.

FOSSiBOT's US warranty and return policy gives the F2400 2 years plus a 3-year extension (5 years in all) for orders from us.fossibot.com only, with returns accepted for 30 days from purchase. FOSSiBOT's global store and the F2400 manual's warranty card say 24 months. All as of October 28, 2026; if you buy from another seller, check the warranty terms with FOSSiBOT first.
The US store sells the F2400 with app control; FOSSiBOT's global store page for the F2400 does not mention an app, so a unit bought elsewhere may not have one. With AC and 500 W of solar at the same time, FOSSiBOT gives about 1.5 hours from 0 to 100%.

FOSSiBOT F2400 questions
How many nights will the FOSSiBOT F2400 run a CPAP?
A ResMed AirSense 11 at its typical 56 W runs about 23 hours on AC power: 2.8 nights of 8 hours. ResMed's typical figure includes its humidifier; a higher humidifier or heated-tube setting raises the draw. Running the CPAP from the 12 V socket with ResMed's DC converter avoids the inverter's own draw.
How long does the FOSSiBOT F2400 take to charge?
FOSSiBOT states 2 h to full from a wall outlet, and up to 500 W of solar input.
Can you add batteries to the FOSSiBOT F2400?
No. FOSSiBOT says it does not take extra batteries, so 2,048 Wh is the most it holds.
What battery does the FOSSiBOT F2400 use?
LiFePO4, rated by FOSSiBOT for 4,000+ cycles to 80% original capacity.
