How long will an EcoFlow RIVER Pro run a drone battery charger?
About 5.5 hours — 5 h 31 min typically, from 5 h 11 min in the worst case to 5 h 50 min at best. That assumes a drone battery charger pulling 80 W continuously, plus the station's 10 W AC mains socket overhead — 90 W in total out of 496 usable watt-hours.
Fast chargers pull hard for a short time — check the charger's own rating, not the drone's.
The numbers
| Setup | Average draw | Cautious | Typical | Best case |
|---|---|---|---|---|
| 1 × drone battery charger, UK 230 V | 90 W | 5 h 11 min | 5 h 31 min | 5 h 50 min |
| 2 × drone battery charger, UK 230 V | 170 W | 2 h 44 min | 2 h 55 min | 3 h 5 min |
| 1 × drone battery charger, US 120 V | 90 W | 5 h 11 min | 5 h 31 min | 5 h 50 min |
- 0.7 nights of eight hours, or 0.23 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 2,972 Wh of rated capacity — 4.1× this station.
- Start-up: the drone battery charger asks for 80 W at switch-on against this station's 1,200 W peak — comfortable.
