How Long Will It Run

How long will an EcoFlow RIVER Pro run a heated jacket battery?

A little over a day — 24 h 55 min typically, from 23 h 52 min in the worst case to 25 h 27 min at best. That assumes a heated jacket battery pulling 20 W continuously, plus the station's 2 W USB-C / USB-A overhead — 22 W in total out of 548 usable watt-hours.

This appliance runs from the station's USB-C / USB-A, which skips the inverter — that is worth roughly 11% more running time than the same load through a mains socket.

  • 3.1 nights of eight hours, or 1.04 days of continuous running.
  • Usable energy: 548 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 896 Wh of rated capacity — 1.2× this station.
  • Start-up: the heated jacket battery asks for 20 W at switch-on against this station's 1,200 W peak — comfortable.

If this is for a power cut

For warmth without a power station, a power bank runs USB heated clothing for hours, and the no-power options cost pennies.

Without a power station: a 20,000 mAh power bank runs a USB heated gilet for about 7 h 24 min. See the power bank numbers.

Hand warmers. Air-activated packs give hours of heat with no power at all, and a pocketful helps children and older relatives.

Look for: Long-duration packs, and the expiry date on bulk boxes.

Fleece blankets or sleeping bags. Layers and a warm bed do more than any heater a battery can run.

Look for: Whatever you would take camping; a sleeping bag rated for the season is warmer than a duvet.
