How long will an EcoFlow RIVER 2 run LED Christmas tree lights (500 bulbs)?
About 4.3 hours — 4 h 20 min typically, from 4 h 4 min in the worst case to 4 h 35 min at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 8 W AC mains socket overhead — 43 W in total out of 186 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
