What will the ALLPOWERS R3500 run?
The ALLPOWERS R3500 stores 3,168Wh with 3,200W of output (6,000W surge). Running one thing at a time, that's about 26 to 55 hours of a refrigerator, about 3 to 7 days of a CPAP with the humidifier off and about 3 to 5 days of Wi-Fi.
3,168 Wh and 3,200 W from 120 V outlets, expandable to 6,336 Wh with one extra battery. It switches over in under 15 ms, but ALLPOWERS says UPS mode is capped at 1,500 W because it passes through a normal 15 A outlet. Its certification line lists UL without naming a standard. At 93 lb it's not one to carry far, and it's 120 V only.

Runtime: 3,168Wh × 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 ALLPOWERS R3500 run a refrigerator?
Yes. It runs one for about 26 to 55 hours on its own, and its output and surge rating cover the cautious figures on generator makers' charts.
How long will the ALLPOWERS R3500 run a CPAP?
About 3 to 7 days with the humidifier and heated tube off, or about 31 to 78 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 ALLPOWERS R3500 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 5 hours. See how to stay warm without power for what works better.
