How long will an EcoFlow RIVER 3 Plus run LED Christmas tree lights (500 bulbs)?
About 4.7 hours — 4 h 43 min typically, from 4 h 27 min in the worst case to 5 h at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 9 W AC mains socket overhead — 44 W in total out of 208 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
