How Long Will It Run

How long will a Bluetti AC300 + B300 run a garden inflatable (christmas or halloween)?

A little over a day — 32 h 50 min typically, from 30 h 54 min in the worst case to 34 h 46 min at best. That assumes a garden inflatable (christmas or halloween) pulling 50 W continuously, plus the station's 18 W AC mains socket overhead — 68 W in total out of 2,233 usable watt-hours.

The fan runs the whole time it is standing up, so the hours it is on decide the cost.
