How long will a DJI Power 500 run LED Christmas tree lights (500 bulbs)?
About 8.5 hours — 8 h 28 min typically, from 7 h 58 min in the worst case to 8 h 57 min at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 9 W AC mains socket overhead — 44 W in total out of 372 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
