How Long Will It Run

How long will an EcoFlow RIVER Pro run LED Christmas tree lights (500 bulbs)?

About 11 hours — 11 h 1 min typically, from 10 h 22 min in the worst case to 11 h 40 min at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 10 W AC mains socket overhead — 45 W in total out of 496 usable watt-hours.

About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.

  • 1.4 nights of eight hours, or 0.46 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 1,486 Wh of rated capacity — 2.1× this station.
  • Start-up: the LED Christmas tree lights (500 bulbs) asks for 35 W at switch-on against this station's 1,200 W peak — comfortable.
