How long will an EcoFlow RIVER 3 Plus run a heated clothes airer?
About an hour — 40 min typically, from 38 min in the worst case to 43 min at best. That assumes a heated clothes airer pulling 300 W continuously, plus the station's 9 W AC mains socket overhead — 309 W in total out of 208 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.
The numbers
| Setup | Average draw | Cautious | Typical | Best case |
|---|---|---|---|---|
| 1 × heated clothes airer, UK 230 V | 309 W | 38 min | 40 min | 43 min |
| 2 × heated clothes airer, UK 230 V | 609 W | 19 min | 20 min | 22 min |
| 1 × heated clothes airer, US 120 V | 309 W | 38 min | 40 min | 43 min |
- 0.1 nights of eight hours, or 0.03 days of continuous running.
- Usable energy: 208 Wh of the 286 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 10,204 Wh of rated capacity — 35.7× this station.
- Start-up: the heated clothes airer asks for 300 W at switch-on against this station's 1,200 W peak — comfortable.
