How long will a Bluetti AC300 + B300 run a heated clothes airer?
About 7 hours — 7 h 1 min typically, from 6 h 37 min in the worst case to 7 h 26 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 2,233 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.
