How Long Will It Run

How long will an ALLPOWERS R1500 run incandescent Christmas tree lights (500 bulbs)?

About 3.9 hours — 3 h 53 min typically, from 3 h 39 min in the worst case to 4 h 6 min at best. That assumes incandescent Christmas tree lights (500 bulbs) pulling 204 W continuously, plus the station's 12 W AC mains socket overhead — 216 W in total out of 837 usable watt-hours.

The old bulbs draw about six times what LEDs do for the same tree, and run hot.
