How long will an EcoFlow RIVER Pro run an electric blanket?
About 16 hours — 15 h 59 min typically, from 15 h 3 min in the worst case to 16 h 56 min at best. That assumes an electric blanket pulling 60 W for 35% of the time (average 21 W), plus the station's 10 W AC mains socket overhead — 31 W in total out of 496 usable watt-hours.
Note how much of that draw is the station rather than the appliance: 32% of the energy goes on keeping the inverter awake. On a load this small, the idle draw matters more than the capacity does.
The numbers
| Setup | Average draw | Cautious | Typical | Best case |
|---|---|---|---|---|
| 1 × electric blanket, UK 230 V | 31 W | 15 h 3 min | 15 h 59 min | 16 h 56 min |
| 2 × electric blanket, UK 230 V | 52 W | 8 h 58 min | 9 h 32 min | 10 h 5 min |
| 1 × electric blanket, US 120 V | 31 W | 15 h 3 min | 15 h 59 min | 16 h 56 min |
- 2 nights of eight hours, or 0.67 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 1,024 Wh of rated capacity — 1.4× this station.
- Start-up: the electric blanket asks for 60 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.

What changes the answer
| If instead… | Typical runtime | Change |
|---|---|---|
| The pack is two years old | 14 h 43 min | -8% |
| The pack is five years old | 12 h 47 min | -20% |
| It is −10 °C outside | 12 h 47 min | -20% |
| You run it flat, no reserve | 17 h 46 min | +11% |
| You keep 20% back | 14 h 13 min | -11% |
Thermostatic, so it is on for about a third of the night — one of the few heating loads a battery handles gracefully.
