Power Requirements for Bounce Houses
Bounce houses stay inflated using a powerful air blower that runs continuously during the event. This blower pushes air into the inflatable so it remains firm while children are jumping and playing inside.
Most residential bounce houses run on standard household electricity. However, the blower must be connected to a reliable power source because if the blower stops, the inflatable will slowly deflate.
How Bounce House Blowers Work
A bounce house blower constantly pushes air into the inflatable through an air tube. Unlike a balloon, bounce houses are not sealed airtight. Small seams allow air to escape, so the blower must run the entire time the inflatable is in use.
If the blower is turned off or loses power, the bounce house will gradually deflate.
Typical Electrical Requirements
Most bounce house blowers operate on standard 115–120 volt power and draw between 7 and 14 amps depending on the size of the blower.
For best performance, the blower should be connected to a dedicated 20-amp circuit. This helps prevent circuit breakers from tripping if other appliances are running on the same line.
Power Needs by Bounce House Size
Different inflatable sizes require different blower power levels.
- Small bounce houses: usually use a 1 HP blower requiring around 800–1,200 watts.
- Medium combo units: often use a 1.5 HP blower requiring about 1,500 watts.
- Large obstacle courses: may require a 2 HP blower or multiple blowers using 2,000–3,000 watts or more.
Larger inflatables sometimes use two blowers to maintain proper air pressure.
Extension Cord Guidelines
Extension cords are commonly used for backyard setups, but they must be heavy-duty cords designed for outdoor equipment.
- Use outdoor-rated extension cords.
- Heavy-duty cords (12-gauge) work best.
- Avoid running cords longer than 50–100 feet.
Long extension cords can reduce voltage and cause the blower motor to overheat.
When You May Need a Generator
Generators are typically used when bounce houses are installed in locations without electrical outlets.
Common situations where generators are needed include:
- Parks or outdoor venues without power outlets.
- Large backyards where the setup area is far from the house.
- Events with multiple inflatables or equipment.
Choosing the Right Generator
If a generator is required, it must provide enough power for both startup and continuous operation.
- A 2,000-watt generator is usually sufficient for one medium bounce house.
- A 4,000-watt generator may be needed for multiple inflatables.
- Always allow extra power capacity for startup surge.
Never refuel a generator while it is running, and keep it placed away from the bounce house for safety.
