How long will a Zendure SuperBase V6400 run a heated clothes airer?
About 14 hours — 13 h 46 min typically, from 12 h 58 min in the worst case to 14 h 35 min at best. That assumes a heated clothes airer pulling 300 W continuously, plus the station's 22 W AC mains socket overhead — 322 W in total out of 4,433 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 |
|---|---|---|---|---|

- 1.7 nights of eight hours, or 0.57 days of continuous running.
- Usable energy: 4,433 Wh of the 6,438 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 10,634 Wh of rated capacity — 1.7× this station.
- Start-up: the heated clothes airer asks for 300 W at switch-on against this station's 7,600 W peak — comfortable.
