What will the FOSSiBOT F1800 run?
The FOSSiBOT F1800 stores 1,024Wh with 1,800W of output. Running one thing at a time, that's about 8.5 to 18 hours of a refrigerator, about 26 to 56 hours of a CPAP with the humidifier off and about 28 to 39 hours of Wi-Fi.
1,024Wh and 1,800W at 24.8 lb, rated for 4,000 cycles to 80%, by FOSSiBOT's page and Amazon listing. FOSSiBOT gives two surge figures (3,600W, and 2,700W in its FAQ), so we list none.

Runtime: 1,024Wh × 90% usable × 85% inverter efficiency ÷ (the average draw + about 10W the station uses itself), from Energy Star figures and makers' manuals. "Runs it?" checks its output against the cautious running and starting figures on generator makers' and DTE Energy's charts. Plan on the low end. Your own list: the power station calculator.
Questions
Can the FOSSiBOT F1800 run a refrigerator?
Probably, for about 8.5 to 18 hours, but check first: surge rating not listed: check it. Modern refrigerators often start with less than the charts' cautious figure.
How long will the FOSSiBOT F1800 run a CPAP?
About 26 to 56 hours with the humidifier and heated tube off, or about 10 to 25 hours with them on, running nothing else. Running it from the 12V outlet through the CPAP maker's own converter avoids the inverter's losses, so it lasts longer than these figures.
Can the FOSSiBOT F1800 run a space heater?
Only briefly: a space heater on high draws up to about 1,500 watts, so it lasts about 0.5 to 1.5 hours. See how to stay warm without power for what works better.
