How long will a Goal Zero Yeti 1000 run LED Christmas tree lights (500 bulbs)?
About 16 hours — 15 h 46 min typically, from 14 h 50 min in the worst case to 16 h 41 min at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 11 W AC mains socket overhead — 46 W in total out of 725 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
