How Long Will It Run

How long will an EcoFlow RIVER Pro run a projector?

About 1.9 hours — 1 h 55 min typically, from 1 h 47 min in the worst case to 2 h 1 min at best. That assumes a projector pulling 250 W continuously, plus the station's 10 W AC mains socket overhead — 260 W in total out of 496 usable watt-hours.

Lamp projectors are thirsty; a modern LED or laser projector may be a third of this.

  • 0.2 nights of eight hours, or 0.08 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 8,586 Wh of rated capacity — 11.9× this station.
  • Start-up: the projector asks for 250 W at switch-on against this station's 1,200 W peak — comfortable.
