How Long Will It Run

How long will an EcoFlow RIVER Pro run a Nintendo Switch (docked)?

About 18 hours — 17 h 42 min typically, from 16 h 40 min in the worst case to 18 h 45 min at best. That assumes a Nintendo Switch (docked) pulling 18 W continuously, plus the station's 10 W AC mains socket overhead — 28 W in total out of 496 usable watt-hours.

Note how much of that draw is the station rather than the appliance: 36% of the energy goes on keeping the inverter awake. On a load this small, the idle draw matters more than the capacity does.

  • 2.2 nights of eight hours, or 0.74 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 925 Wh of rated capacity — 1.3× this station.
  • Start-up: the Nintendo Switch (docked) asks for 18 W at switch-on against this station's 1,200 W peak — comfortable.
