How long will an EcoFlow RIVER Pro run a heated blanket, 12 V?
About 22 hours — 21 h 54 min typically, from 20 h 57 min in the worst case to 22 h 37 min at best. That assumes a heated blanket, 12 V pulling 45 W for 50% of the time (average 23 W), plus the station's 2 W 12 V DC socket overhead — 25 W in total out of 537 usable watt-hours.
This appliance runs from the station's 12 V DC socket, which skips the inverter — that is worth roughly 8% more running time than the same load through a mains socket.
The numbers
| Setup | Average draw | Cautious | Typical | Best case |
|---|---|---|---|---|
| 1 × heated blanket, 12 V, UK 230 V | 25 W | 20 h 57 min | 21 h 54 min | 22 h 37 min |
| 2 × heated blanket, 12 V, UK 230 V | 47 W | 10 h 55 min | 11 h 25 min | 11 h 47 min |
| 1 × heated blanket, 12 V, US 120 V | 25 W | 20 h 57 min | 21 h 54 min | 22 h 37 min |
- 2.7 nights of eight hours, or 0.91 days of continuous running.
- Usable energy: 537 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 992 Wh of rated capacity — 1.4× this station.
- Start-up: the heated blanket, 12 V asks for 45 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.

What changes the answer
| If instead… | Typical runtime | Change |
|---|---|---|
| The pack is two years old | 20 h 9 min | -8% |
| The pack is five years old | 17 h 31 min | -20% |
| It is −10 °C outside | 17 h 31 min | -20% |
| You run it flat, no reserve | 24 h 20 min | +11% |
| You keep 20% back | 19 h 28 min | -11% |
Runs off the car socket and avoids the inverter entirely — the efficient way to stay warm in a van.
