How long will a Bluetti AC240 run LED Christmas tree lights (500 bulbs)?
About 23 hours — 22 h 47 min typically, from 21 h 26 min in the worst case to 24 h 7 min at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 14 W AC mains socket overhead — 49 W in total out of 1,116 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
