How long will a Goal Zero Yeti 300 run LED Christmas tree lights (500 bulbs)?
About 5 hours — 5 h 1 min typically, from 4 h 43 min in the worst case to 5 h 19 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 216 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
