How long will an EcoFlow RIVER 3 run LED Christmas tree lights (500 bulbs)?
About 4.1 hours — 4 h 8 min typically, from 3 h 54 min in the worst case to 4 h 23 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 178 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
