How long will an EcoFlow DELTA Pro run a garden inflatable (christmas or halloween)?
About 1.6 days — 38 h 28 min typically, from 36 h 13 min in the worst case to 40 h 44 min at best. That assumes a garden inflatable (christmas or halloween) pulling 50 W continuously, plus the station's 18 W AC mains socket overhead — 68 W in total out of 2,616 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 | 68 W | 36 h 13 min | 38 h 28 min | 40 h 44 min |
| 2 × garden inflatable (christmas or halloween), UK 230 V | 118 W | 20 h 52 min | 22 h 10 min | 23 h 29 min |
| 1 × garden inflatable (christmas or halloween), US 120 V | 68 W | 36 h 13 min | 38 h 28 min | 40 h 44 min |
- 4.8 nights of eight hours, or 1.6 days of continuous running.
- Usable energy: 2,616 Wh of the 3,600 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 2,246 Wh of rated capacity — which this station has.
- Start-up: the garden inflatable (christmas or halloween) asks for 50 W at switch-on against this station's 7,200 W peak — comfortable.
