How long will an EcoFlow RIVER Pro run a heated throw?
About 9.9 hours — 9 h 55 min typically, from 9 h 20 min in the worst case to 10 h 30 min at best. That assumes a heated throw pulling 100 W for 40% of the time (average 40 W), plus the station's 10 W AC mains socket overhead — 50 W in total out of 496 usable watt-hours.
Bigger and warmer than a blanket; still cheap compared with heating the room.
The numbers
| Setup | Average draw | Cautious | Typical | Best case |
|---|---|---|---|---|
| 1 × heated throw, UK 230 V | 50 W | 9 h 20 min | 9 h 55 min | 10 h 30 min |
| 2 × heated throw, UK 230 V | 90 W | 5 h 11 min | 5 h 31 min | 5 h 50 min |
| 1 × heated throw, US 120 V | 50 W | 9 h 20 min | 9 h 55 min | 10 h 30 min |
- 1.2 nights of eight hours, or 0.41 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 1,651 Wh of rated capacity — 2.3× this station.
- Start-up: the heated throw asks for 100 W at switch-on against this station's 1,200 W peak — comfortable.

If this is for a power cut
Heating is what a battery does worst. In a power cut, warming people rather than rooms goes much further, and none of this needs a socket.
Without a power station: a 20,000 mAh power bank runs a USB heated throw for about 7 h 24 min. See the power bank numbers.
Hot water bottle and a vacuum flask. Boil water while you still can, keep it hot in a flask, and refill the bottle through the night.
Look for: A bottle made to BS 1970 in the UK, and a flask of a litre or more.
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.
