What will the EcoFlow RIVER 2 Pro run?
The EcoFlow RIVER 2 Pro stores 768Wh with 800W of output (1,600W surge). Running one thing at a time, that's about 6.5 to 13 hours of a refrigerator if it can start one (see below), about 20 to 42 hours of a CPAP with the humidifier off and about 21 to 29 hours of Wi-Fi.
768 Wh in an 18 lb box: phones, laptops, lights, a CPAP or a small fridge for a few hours. The 800 W output limits what you can plug in at once.

A few things together
| Running together | Runs them for | Runs it? |
|---|---|---|
| Refrigerator, Wi-Fi and four LED bulbs | 4 to 7 hours | Nomay not start it (surge 1,600W) |
| Refrigerator, freezer and Wi-Fi | – | Noneeds 810W+ |
| CPAP (humidifier off) and one LED bulb | 15 to 27 hours | Yes |
| Wi-Fi, a laptop and two LED bulbs | 5 to 9 hours | Yes |
Runtime: 768Wh × 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 RIVER 2 Pro run a refrigerator?
Not reliably: may not start it (surge 1,600W). If it does run one, it lasts about 6.5 to 13 hours.
How long will the EcoFlow RIVER 2 Pro run a CPAP?
About 20 to 42 hours with the humidifier and heated tube off, or about 7.5 to 19 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 RIVER 2 Pro run a space heater?
Only briefly: a space heater on high draws up to about 1,500 watts, so it lasts about 0.5 to 1 hour. See how to stay warm without power for what works better.
