How long will an Anker SOLIX F3800 run a heated clothes airer?
About 8.8 hours — 8 h 47 min typically, from 8 h 16 min in the worst case to 9 h 17 min at best. That assumes a heated clothes airer pulling 300 W continuously, plus the station's 18 W AC mains socket overhead — 318 W in total out of 2,791 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 | 318 W | 8 h 16 min | 8 h 47 min | 9 h 17 min |

- 1.1 nights of eight hours, or 0.37 days of continuous running.
- Usable energy: 2,791 Wh of the 3,840 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 10,502 Wh of rated capacity — 2.7× this station.
- Start-up: the heated clothes airer asks for 300 W at switch-on against this station's 8,000 W (230 V) / 9,000 W (120 V) peak — comfortable.
