How Long Will It Run

How long will an EcoFlow RIVER Pro run a bait freezer (small chest)?

About 11 hours — 11 h 16 min typically, from 10 h 36 min in the worst case to 11 h 56 min at best. That assumes a bait freezer (small chest) pulling 85 W for 40% of the time (average 34 W), plus the station's 10 W AC mains socket overhead — 44 W in total out of 496 usable watt-hours.

Sits outdoors, so a cold night cuts the duty cycle and a hot day raises it sharply.

  • 1.4 nights of eight hours, or 0.47 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 1,453 Wh of rated capacity — 2× this station.
  • Start-up: the bait freezer (small chest) asks for 500 W at switch-on against this station's 1,200 W peak — comfortable.
