How long will an ALLPOWERS R1500 run a garden inflatable (christmas or halloween)?
About 14 hours — 13 h 30 min typically, from 12 h 43 min in the worst case to 14 h 18 min at best. That assumes a garden inflatable (christmas or halloween) pulling 50 W continuously, plus the station's 12 W AC mains socket overhead — 62 W in total out of 837 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 | 62 W | 12 h 43 min | 13 h 30 min | 14 h 18 min |
| 2 × garden inflatable (christmas or halloween), UK 230 V | 112 W | 7 h 2 min | 7 h 29 min | 7 h 55 min |
| 1 × garden inflatable (christmas or halloween), US 120 V | 62 W | 12 h 43 min | 13 h 30 min | 14 h 18 min |
- 1.7 nights of eight hours, or 0.56 days of continuous running.
- Usable energy: 837 Wh of the 1,152 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 2,048 Wh of rated capacity — 1.8× this station.
- Start-up: the garden inflatable (christmas or halloween) asks for 50 W at switch-on against this station's 2,700 W peak — comfortable.
