What will the Dabbsson 2000L run?
The Dabbsson 2000L stores 2,048Wh with 2,200W of output (3,300W surge). Running one thing at a time, that's about 17 to 36 hours of a refrigerator, about 2 to 4 days of a CPAP with the humidifier off and about 2 to 3 days of Wi-Fi.

Runtime: 2,048Wh × 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 and surge rating against the cautious running and starting figures on generator makers' and DTE Energy's charts. Plan on the low end.

Questions
Can the Dabbsson 2000L run a refrigerator?
Yes. It runs one for about 17 to 36 hours on its own, and its output and surge rating cover the cautious figures on generator makers' charts.
How long will the Dabbsson 2000L run a CPAP?
About 2 to 4 days with the humidifier and heated tube off, or about 20 to 51 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 Dabbsson 2000L run a space heater?
Only briefly: a space heater on high draws up to about 1,500 watts, so it lasts about 1 to 3 hours. See how to stay warm without power for what works better.
