How long will an ALLPOWERS R1500 run LED Christmas tree lights (500 bulbs)?
About 18 hours — 17 h 49 min typically, from 16 h 46 min in the worst case to 18 h 52 min at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 12 W AC mains socket overhead — 47 W in total out of 837 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
