How long will a VTOMAN FlashSpeed 1500 run a garden inflatable (christmas or halloween)?
About 18 hours — 18 h 9 min typically, from 17 h 5 min in the worst case to 19 h 13 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 1,125 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 | 17 h 5 min | 18 h 9 min | 19 h 13 min |
| 2 × garden inflatable (christmas or halloween), UK 230 V | 112 W | 9 h 27 min | 10 h 2 min | 10 h 38 min |
| 1 × garden inflatable (christmas or halloween), US 120 V | 62 W | 17 h 5 min | 18 h 9 min | 19 h 13 min |
- 2.3 nights of eight hours, or 0.76 days of continuous running.
- Usable energy: 1,125 Wh of the 1,548 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 — 1.3× this station.
- Start-up: the garden inflatable (christmas or halloween) asks for 50 W at switch-on against this station's 3,000 W peak — comfortable.
