How long will an EcoFlow DELTA Max 1600 run incandescent Christmas tree lights (500 bulbs)?
About 5.1 hours — 5 h 5 min typically, from 4 h 47 min in the worst case to 5 h 23 min at best. That assumes incandescent Christmas tree lights (500 bulbs) pulling 204 W continuously, plus the station's 13 W AC mains socket overhead — 217 W in total out of 1,103 usable watt-hours.
The old bulbs draw about six times what LEDs do for the same tree, and run hot.
