How long will an EcoFlow DELTA 2 Max run LED Christmas tree lights (500 bulbs)?
A little over a day — 30 h 23 min typically, from 28 h 35 min in the worst case to 32 h 10 min at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 14 W AC mains socket overhead — 49 W in total out of 1,488 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
