How Long Will It Run

How long will an EcoFlow RIVER 2 Pro run a heated clothes airer?

About 1.8 hours — 1 h 48 min typically, from 1 h 41 min in the worst case to 1 h 55 min at best. That assumes a heated clothes airer pulling 300 W continuously, plus the station's 10 W AC mains socket overhead — 310 W in total out of 558 usable watt-hours.

No thermostat on most models, so it draws its full rating for as long as it is on — a cover over the load dries it faster and saves hours.

  • 0.2 nights of eight hours, or 0.08 days of continuous running.
  • Usable energy: 558 Wh of the 768 Wh on the box, after chemistry, inverter losses and the reserve.
  • To keep it going for a full 24 hours you would need about 10,237 Wh of rated capacity — 13.3× this station.
  • Start-up: the heated clothes airer asks for 300 W at switch-on against this station's 1,600 W peak — comfortable.
