Key Takeaways:
When you’re setting up a HeroKiddo event, the fun starts with the inflatables. But behind every bounce house or water slide is something you can’t forget—electricity needs.
From small school carnivals to large rental events, the power setup is one of the most important parts of planning. Each inflatable needs a blower. That blower needs a safe, steady source of power. And if you’re using multiple commercial grade bounce houses, the power requirements add up fast.
If you plug too many blowers into one circuit, you risk tripping breakers or losing power in the middle of the event. That’s not just frustrating—it can also be unsafe.
This blog will walk you through how to plan your bounce house power, use the right cords, and choose the best generator types when outlets aren’t available. Whether you're a school staff member, rental operator, or community event planner, this guide is for you.
Most HeroKiddo inflatables use a standard inflatable blower. These blowers keep constant air moving through the affordable inflatable bounce house. Without that air, the unit deflates quickly. That’s why steady power is key.
One blower usually uses 6.5 to 8.8 amps and needs a 110V outlet. Most require about 1000 to 1150 continuous watts. This varies slightly depending on the blower size and airflow system.
A standard 15-amp household circuit can usually handle one blower safely. But once you add more units, you’ll need more circuits—or a dedicated power source like a generator or power distribution unit.
If you're powering multiple bounce houses, never plug more than one blower into a single 15-amp circuit. Doing so risks overheating, breaker trips, and possible damage to the blower or electrical components.
Instead, use this basic formula:
One blower = One 15-amp circuit
Two bounce houses = Two 15-amp circuits or one 20-amp circuit with proper power spacing
Three or more units = Use generator rentals or split power across separate circuits
Make sure you know where the breakers are before your event. If you’re at a park, ask if they have a map of outlet locations. Always test the power ahead of time.
Use heavy-duty extension cords rated for outdoor use. Shorter is better. Longer cords lose power and can heat up fast. Make sure they are at least 12-gauge and UL-rated.
Never daisy-chain cords or run them through water. Tape them down to avoid tripping and keep them away from air outlet chutes and air vents.
Also, avoid overloading any plug. Make sure every bounce house power connection is direct and clear. Do not let cords cross walkways, sharp objects, or heavy foot traffic without cover.
If your event is in a park, field, or space with no outlets, you’ll need a generator. When choosing one, focus on generator size, wattage rating, and fuel efficiency.
One inflatable blower needs about 1000 to 1200 running watts. But always plan for the startup surge, which may be 2 to 3 times higher.
For example:
A good rule is to use a generator rated for 4000–6000 watts if powering 2 to 3 inflatables. Always go above what you need to avoid power drops.
If you're renting, tell the provider what you're powering. Look for inverter generators if you want cleaner, quieter power, especially for indoor bounce house events.
Check the fuel tank and fuel capacities before the event. Bring extra gallons of gas in case your event runs long. Most blowers run all day, so the generator must too.
Place generators away from the play area. Keep them on flat ground and at least 10 feet from inflatables. Never place them inside tents or enclosed spaces. Exhaust fumes are dangerous.
Use safety features like watchdog alarm systems and keep kids away with cones or fences. If you’re using multiple generators, label which inflatable each one powers to avoid confusion.
Some events are inside gyms or community centers. In these cases, power is usually available—but you still need to plan your power setup.
Run cords from multiple walls if possible. Spread out the electrical box usage and don’t rely on a single outlet. Ask the venue if you can test the circuit breaker loads before the event.
Also, remember indoor rules: no water slides, no exhaust fumes, and careful cord placement. Tape down cords and keep air vents clear.
Before your event, make a power setup plan. Walk your site. Count the number of blowers you’ll use. Know the amp rating on each outlet.
Print out a power map and label where each blower will plug in. Color-code outlets or cords if needed. Having a simple chart can prevent problems on event day.
Share this plan with your team. If someone needs to reset a breaker or move a blower, they’ll know where to go.
Start with the basics. One blower = one circuit. Then build out. For three or more units, spread out your power use or add generator rentals. Never plug all inflatables into one source.
Use safe cords, plan for startup surge watts, and give each unit its own space. Whether you're using wall power of commercial inflatable or bounce house castle blower generators, plan ahead and keep safety first.
HeroKiddo inflatables are fun, bright, and built for business—but the fun doesn’t start without power. By planning your bounce house power the right way, you’ll keep everything inflated, safe, and running smoothly. Whether you’re using one unit or ten, these power requirements tips will keep your event on track from start to finish.
