What will the EcoFlow DELTA 3 Ultra Plus run?
The EcoFlow DELTA 3 Ultra Plus stores 3,072Wh with 3,600W of output (7,200W surge). Running one thing at a time, that's about 25 to 53 hours of a refrigerator, about 3 to 6 days of a CPAP with the humidifier off and about 3 to 4 days of Wi-Fi.
The DELTA 3 Ultra's 3,072Wh and 3,600W with 1,600W of solar input instead of 800W, by EcoFlow's figures. Only worth it if you'll run big solar arrays.

Runtime: 3,072Wh × 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 EcoFlow DELTA 3 Ultra Plus run a refrigerator?
Yes. It runs one for about 25 to 53 hours on its own, and its output and surge rating cover the cautious figures on generator makers' charts.
How long will the EcoFlow DELTA 3 Ultra Plus run a CPAP?
About 3 to 6 days with the humidifier and heated tube off, or about 31 to 76 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 EcoFlow DELTA 3 Ultra Plus run a space heater?
Only briefly: a space heater on high draws up to about 1,500 watts, so it lasts about 1.5 to 4.5 hours. See how to stay warm without power for what works better.
