How long will a Bluetti EB70S run a heated clothes airer?
About 1.7 hours — 1 h 41 min typically, from 1 h 35 min in the worst case to 1 h 47 min at best. That assumes a heated clothes airer pulling 300 W continuously, plus the station's 10 W AC mains socket overhead — 310 W in total out of 520 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 | 310 W | 1 h 35 min | 1 h 41 min | 1 h 47 min |
| 2 × heated clothes airer, UK 230 V | 610 W | 48 min | 51 min | 54 min |
| 1 × heated clothes airer, US 120 V | 310 W | 1 h 35 min | 1 h 41 min | 1 h 47 min |
- 0.2 nights of eight hours, or 0.07 days of continuous running.
- Usable energy: 520 Wh of the 716 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 10,237 Wh of rated capacity — 14.3× this station.
- Start-up: the heated clothes airer asks for 300 W at switch-on against this station's 1,400 W peak — comfortable.
