How Long Will It Run

How long will a DJI Power 500 run incandescent Christmas tree lights (500 bulbs)?

About 1.8 hours — 1 h 45 min typically, from 1 h 38 min in the worst case to 1 h 51 min at best. That assumes incandescent Christmas tree lights (500 bulbs) pulling 204 W continuously, plus the station's 9 W AC mains socket overhead — 213 W in total out of 372 usable watt-hours.

The old bulbs draw about six times what LEDs do for the same tree, and run hot.

  • Usable energy: 372 Wh of the 512 Wh on the box, after chemistry, inverter losses and the reserve.
  • To keep it going for a full 24 hours you would need about 7,034 Wh of rated capacity — 13.7× this station.
  • Start-up: the incandescent Christmas tree lights (500 bulbs) asks for 204 W at switch-on against this station's 2,200 W peak — comfortable.
