How long will a Goal Zero Yeti 1500X run a garden inflatable (christmas or halloween)?
About 17 hours — 16 h 34 min typically, from 15 h 35 min in the worst case to 17 h 32 min at best. That assumes a garden inflatable (christmas or halloween) pulling 50 W continuously, plus the station's 13 W AC mains socket overhead — 63 W in total out of 1,044 usable watt-hours.
The fan runs the whole time it is standing up, so the hours it is on decide the cost.
The numbers
| Setup | Average draw | Cautious | Typical | Best case |
|---|---|---|---|---|
| 1 × garden inflatable (christmas or halloween), UK 230 V | 63 W | 15 h 35 min | 16 h 34 min | 17 h 32 min |
| 2 × garden inflatable (christmas or halloween), UK 230 V | 113 W | 8 h 41 min | 9 h 14 min | 9 h 47 min |
| 1 × garden inflatable (christmas or halloween), US 120 V | 63 W | 15 h 35 min | 16 h 34 min | 17 h 32 min |
- 2.1 nights of eight hours, or 0.69 days of continuous running.
- Usable energy: 1,044 Wh of the 1,516 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 2,081 Wh of rated capacity — 1.4× this station.
- Start-up: the garden inflatable (christmas or halloween) asks for 50 W at switch-on against this station's 3,500 W peak — comfortable.
