How Long Will It Run

How long will a Goal Zero Yeti 500 run a garden inflatable (christmas or halloween)?

About 6.2 hours — 6 h 9 min typically, from 5 h 47 min in the worst case to 6 h 31 min at best. That assumes a garden inflatable (christmas or halloween) pulling 50 W continuously, plus the station's 9 W AC mains socket overhead — 59 W in total out of 363 usable watt-hours.

The fan runs the whole time it is standing up, so the hours it is on decide the cost.

  • 0.8 nights of eight hours, or 0.26 days of continuous running.
  • Usable energy: 363 Wh of the 499 Wh on the box, after chemistry, inverter losses and the reserve.
  • To keep it going for a full 24 hours you would need about 1,948 Wh of rated capacity — 3.9× this station.
  • Start-up: the garden inflatable (christmas or halloween) asks for 50 W at switch-on against this station's 1,000 W peak — comfortable.
