What will the EcoFlow DELTA Pro 3 run?
The EcoFlow DELTA Pro 3 stores 4,096Wh with 4,000W of output (8,000W surge). Running one thing at a time, that's about 33 to 71 hours of a refrigerator, about 4 to 9 days of a CPAP with the humidifier off and about 4 to 6 days of Wi-Fi.
4,096 Wh and 4,000 W in a single wheeled unit, with 120V and 240V output. One unit grows to 12 kWh with two extra batteries; EcoFlow's 48 kWh figure needs three units. At about 113.5 lb it rolls rather than carries.

Runtime: 4,096Wh × 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 Pro 3 run a refrigerator?
Yes. It runs one for about 33 to 71 hours on its own, and its output and surge rating cover the cautious figures on generator makers' charts.
How long will the EcoFlow DELTA Pro 3 run a CPAP?
About 4 to 9 days with the humidifier and heated tube off, or about 41 to 101 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 Pro 3 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.
