What will the EcoFlow DELTA Pro Ultra run?
The EcoFlow DELTA Pro Ultra stores 6,144Wh with 7,200W of output. Running one thing at a time, that's about 2 to 4 days of a refrigerator, about 6 to 13 days of a CPAP with the humidifier off and about 6 to 9 days of Wi-Fi.
A modular inverter and 6,144 Wh battery with 7,200 W at 120V and 240V, and room to grow to 90 kWh (maker). Made to sit in a garage or utility room and power a home's circuits through EcoFlow's home panel.

Runtime: 6,144Wh × 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 against the cautious running and starting figures on generator makers' and DTE Energy's charts. Plan on the low end. Your own list: the power station calculator.
Questions
Can the EcoFlow DELTA Pro Ultra run a refrigerator?
Yes. It runs one for about 2 to 4 days on its own, and its output cover the cautious figures on generator makers' charts.
How long will the EcoFlow DELTA Pro Ultra run a CPAP?
About 6 to 13 days with the humidifier and heated tube off, or about 2 to 6 days 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 Ultra run a space heater?
Only briefly: a space heater on high draws up to about 1,500 watts, so it lasts about 3 to 9 hours. See how to stay warm without power for what works better.
