How Long Will It Run

How long will an EcoFlow RIVER 2 run a garden inflatable (christmas or halloween)?

About 3.2 hours — 3 h 13 min typically, from 3 h 1 min in the worst case to 3 h 24 min at best. That assumes a garden inflatable (christmas or halloween) pulling 50 W continuously, plus the station's 8 W AC mains socket overhead — 58 W in total out of 186 usable watt-hours.

The fan runs the whole time it is standing up, so the hours it is on decide the cost.

  • 0.4 nights of eight hours, or 0.13 days of continuous running.
  • Usable energy: 186 Wh of the 256 Wh on the box, after chemistry, inverter losses and the reserve.
  • To keep it going for a full 24 hours you would need about 1,915 Wh of rated capacity — 7.5× this station.
  • Start-up: the garden inflatable (christmas or halloween) asks for 50 W at switch-on against this station's 600 W peak — comfortable.
