Bouncy castles excite children and attract attention at events, trade fairs or advertising campaigns. But in addition to structure and security, a practical question often arises:
How much electricity does a bouncy castle use – and how much does it really cost to operate?
How much does it cost to operate a bouncy castle?
The good news first: power consumption is significantly lower than many people assume. All you need is the fan, which constantly supplies the bouncy castle with air. Depending on the size and fan, the power consumption is between 1.1 kW and 3.0 kW.
Sample calculations for 6 hours of operation:
| Bouncy castle size | Blower performance | Total power consumption | Electricity costs (approx.) |
|---|---|---|---|
| Small (4x5 m) | 1.1kW | 6.6 kWh | 1,80 € |
| Medium (5x6 m) | 1.5kW | 9.0 kWh | 2,70 € |
| Large (8x6 m or more) | 2.2-3.0kW | 13-18 kWh | 3,90–5,40 € |
Even with large models, electricity costs are often less than €1 per hour. This makes a bouncy castle one of the cheapest event attractions in terms of operating costs.
Why does the fan run continuously?
Bouncy castles don't work like air mattresses. You need a constant airflow as small leaks are normal due to the robust PVC. The fan constantly compensates for this air loss - that's why it runs continuously.
This way you can save electricity
Step 1: Only switch on the fan when necessary
Only start the fan shortly before the start of the event and switch it off again immediately after the end of the event. Every hour less saves money – especially for longer events.
Step 2: Use efficient professional blower
Modern blowers are powerful, quiet and significantly more energy efficient than older models. Look for tested quality (e.g. Gibbons) to permanently reduce electricity costs.
Step 3: Actively control power consumption
Use an electricity meter at the socket to monitor actual consumption. This way you can identify savings potential and realistically calculate your operating costs.
Step 4: Use a high-quality extension cable with a suitable cross section
A cable that is too thin or too long causes loss of voltage - the fan runs inefficiently and uses more power. A cable with a cross section of 2.5 mm² is ideal, especially for longer distances.
Save electricity & appear professional
If you regularly supervise events or rent out bouncy castles, it is worth using efficient professional models with certification. At Happy Fun you get long-lasting inflatables that remain economical to operate even when used frequently.
