What will the BLUETTI Elite 400 run?
The BLUETTI Elite 400 stores 3,840Wh with 2,600W of output (5,200W surge). Running one thing at a time, that's about 31 to 67 hours of a refrigerator, about 4 to 8 days of a CPAP with the humidifier off and about 4 to 6 days of Wi-Fi.
3,840 Wh of LiFePO4 and 2,600 W from four 120 V outlets, with surge BLUETTI rates at 5,200 W: the biggest single BLUETTI box that needs no home install. It weighs 86 lb, it's 120 V only, and its UPS switchover is 15 ms by BLUETTI's figure. Five-year warranty.

Runtime: 3,840Wh × 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 BLUETTI Elite 400 run a refrigerator?
Yes. It runs one for about 31 to 67 hours on its own, and its output and surge rating cover the cautious figures on generator makers' charts.
How long will the BLUETTI Elite 400 run a CPAP?
About 4 to 8 days with the humidifier and heated tube off, or about 38 to 95 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 BLUETTI Elite 400 run a space heater?
Only briefly: a space heater on high draws up to about 1,500 watts, so it lasts about 2 to 6 hours. See how to stay warm without power for what works better.
