How long will a Goal Zero Yeti 500 run a heated clothes airer?
About an hour — 1 h 10 min typically, from 1 h 6 min in the worst case to 1 h 14 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 363 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 | 1 h 6 min | 1 h 10 min | 1 h 14 min |
| 2 × heated clothes airer, UK 230 V | 609 W | — | — | — |
| 1 × heated clothes airer, US 120 V | 309 W | 1 h 6 min | 1 h 10 min | 1 h 14 min |
- 0.2 nights of eight hours, or 0.05 days of continuous running.
- Usable energy: 363 Wh of the 499 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 — 20.4× this station.
- Start-up: the heated clothes airer asks for 300 W at switch-on against this station's 1,000 W peak — comfortable.
