How long will an EcoFlow DELTA Max 1600 run LED Christmas tree lights (500 bulbs)?
About 23 hours — 22 h 59 min typically, from 21 h 38 min in the worst case to 24 h 20 min at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 13 W AC mains socket overhead — 48 W in total out of 1,103 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
