What Size Generator Do I Need to Run a Bounce House?

Generator Size to run a Bounce House

When planning a party with a bounce house, one crucial aspect to consider is the power supply. A bounce house requires a specific amount of power to inflate and maintain its shape, which is typically provided by a generator.

The size of the generator needed depends on several factors, including the size of the bounce house and the number of fans it uses. Here's a comprehensive guide to help you determine the right generator size for your purchase of a bounce house.

Determining the Right Generator Size

For a single bounce house fan, a minimum of 2,000 watts is advisable. If you need to operate two fans, consider upgrading to a 4,000-watt generator, which also allows for additional electrical needs like lighting or charging devices.

Power Consumption of Bounce House Fans

Power Consumtion of Bounce House Fans

The power consumption of bounce house fans varies based on the fan size:

  • Small Bounce Houses: Typically, a 1HP, 7A fan, pushing about 1100 CFM, consumes around 800 watts per hour.
  • Medium Bounce Houses: A 1.5HP, 9A fan, with approximately 1300 CFM, will use about 1,000 watts (1 kilowatt) per hour.
  • Large Bounce Houses: For a 2HP, 14A fan, pushing over 1400 CFM, the usage exceeds 1.6 kilowatts per hour.

Generator Duration for Bounce Houses

When starting your bounce house business, it's crucial to consider power options. While bounce house fans typically run on standard electrical outlets, using a generator is a smart choice for flexibility. However, generators have limited fuel capacities, so keep this in mind when planning.

A standard generator can power a bounce house for about 90 minutes, but opting for a more powerful one with smaller fans can extend the runtime to six to seven hours, ensuring uninterrupted fun for your customers.

Cost of Operating a Bounce House

Consider a scenario using a 2,000-watt generator with a 1-gallon fuel tank and a medium-sized bounce house with a 1-kilowatt fan. An average generator of this capacity consumes about three-quarters of a gallon per hour, providing roughly 80 minutes of runtime. With the current average fuel price of $4.70 per gallon, the cost for this duration is approximately $4.70. However, these figures may vary based on different generator and fan sizes.

Selecting Generators for Bounce Houses

When choosing generators for bounce houses, the noise level is a significant factor. Here are some options:
