How Long Will It Run

How long will an EcoFlow RIVER Pro run a baby monitor?

A little over a day — 30 h 59 min typically, from 29 h 10 min in the worst case to 32 h 49 min at best. That assumes a baby monitor pulling 6 W continuously, plus the station's 10 W AC mains socket overhead — 16 W in total out of 496 usable watt-hours.

Note how much of that draw is the station rather than the appliance: 63% of the energy goes on keeping the inverter awake. On a load this small, the idle draw matters more than the capacity does.

  • 3.9 nights of eight hours, or 1.29 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 528 Wh of rated capacity — which this station has.
  • Start-up: the baby monitor asks for 6 W at switch-on against this station's 1,200 W peak — comfortable.

Tiny load — so tiny that the station's own inverter idle draw costs more than the monitor does.
