How long will a DJI Power 500 run a garden inflatable (christmas or halloween)?
About 6.3 hours — 6 h 19 min typically, from 5 h 56 min in the worst case to 6 h 41 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 372 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 | 59 W | 5 h 56 min | 6 h 19 min | 6 h 41 min |
| 2 × garden inflatable (christmas or halloween), UK 230 V | 109 W | 3 h 13 min | 3 h 25 min | 3 h 37 min |
| 1 × garden inflatable (christmas or halloween), US 120 V | 59 W | 5 h 56 min | 6 h 19 min | 6 h 41 min |
- 0.8 nights of eight hours, or 0.26 days of continuous running.
- 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 1,948 Wh of rated capacity — 3.8× this station.
- Start-up: the garden inflatable (christmas or halloween) asks for 50 W at switch-on against this station's 2,200 W peak — comfortable.
