How long will an EcoFlow RIVER Pro run a dehumidifier, 12 L/day?
About 3.1 hours — 3 h 6 min typically, from 2 h 55 min in the worst case to 3 h 17 min at best. That assumes a dehumidifier, 12 L/day pulling 250 W for 60% of the time (average 150 W), plus the station's 10 W AC mains socket overhead — 160 W in total out of 496 usable watt-hours.
Compressor units cycle with humidity; desiccant models draw more and do not cycle as much.
The numbers
| Setup | Average draw | Cautious | Typical | Best case |
|---|---|---|---|---|
| 1 × dehumidifier, 12 L/day, UK 230 V | 160 W | 2 h 55 min | 3 h 6 min | 3 h 17 min |
| 2 × dehumidifier, 12 L/day, UK 230 V | 310 W | 1 h 31 min | 1 h 36 min | 1 h 41 min |
| 1 × dehumidifier, 12 L/day, US 120 V | 160 W | 2 h 55 min | 3 h 6 min | 3 h 17 min |
- 0.4 nights of eight hours, or 0.13 days of continuous running.
- Usable energy: 496 Wh of the 720 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 5,284 Wh of rated capacity — 7.3× this station.
- Start-up: the dehumidifier, 12 L/day asks for 600 W at switch-on against this station's 1,200 W peak — comfortable.
