How long will a Bluetti Apex 300 run a garden inflatable (christmas or halloween)?
A little over a day — 30 h 26 min typically, from 28 h 39 min in the worst case to 32 h 14 min at best. That assumes a garden inflatable (christmas or halloween) pulling 50 W continuously, plus the station's 16 W AC mains socket overhead — 66 W in total out of 2,009 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 | 66 W | 28 h 39 min | 30 h 26 min | 32 h 14 min |
| 2 × garden inflatable (christmas or halloween), UK 230 V | 116 W | 16 h 18 min | 17 h 19 min | 18 h 20 min |
| 1 × garden inflatable (christmas or halloween), US 120 V | 66 W | 28 h 39 min | 30 h 26 min | 32 h 14 min |
- 3.8 nights of eight hours, or 1.27 days of continuous running.
- Usable energy: 2,009 Wh of the 2,764 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 2,180 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 7,680 W peak — comfortable.
