How long will a Goal Zero Yeti 1500X run LED Christmas tree lights (500 bulbs)?
About 22 hours — 21 h 45 min typically, from 20 h 28 min in the worst case to 23 h 1 min at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 13 W AC mains socket overhead — 48 W in total out of 1,044 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
