5 Best generators for bounce houses reviewed

If you know more or less how much power you need, the list of top picks and the performance table could be enough to make a choice.

On the other hand, checking out the more detailed reviews of the best generators for bounce houses could still make your decision easier.

1. Westinghouse iGen2500 – Best generator for a bounce house

Our top pick for the best generator for a bounce house is the Westinghouse iGen2500 thanks to its suitable power capacity, great features, and reasonable price.

Westinghouse iGen2500

First of all, even 2 HP blowers for bigger bounce houses “only” tend to need around 2000 running watts so the Westinghouse iGen2500 even offers some spare power.

Secondly, there is a version of the Westinghouse iGen2500 which has a CO sensor. With this, the generator turns off when there is too much carbon monoxide around it.

This may put your mind more at ease for children who do come near the generator. Even though they shouldn’t.

Pros

  • Westinghouse iGen2500 offers 2500 starting watts, 2200 running watts, 20.8 amps, and 120 volts
  • Relatively low noise levels of 52 dBA
  • Good run time of 12 hours at 25% load
  • Good fuel efficiency
  • Less than 3% THD
  • Light weight of 47.4 lb (21.5 kg)
  • Optional CO sensor
  • Very positive customer reviews
  • 3 years limited residential and 1 year limited commercial warranties
  • A lot of customers

Cons

  • A few very exceptional cases of initial technical issues

The Westinghouse iGen2500 also has a nice run time of 12 hours at 25% load. This makes it so you have to interrupt your bounce house party for refuel sessions less often.

One thing to note is that there are a few cases where customers initially have issues with this portable generator.

Support does seem to resolve these issues but you may want to test your Westinghouse iGen2500 at least a few days before the bounce house rental arrives.

That being said, the Westinghouse iGen2500 is still relatively reliable overall.

In combination with the other solid features and reasonable price, this generator is the best general option for running a bounce house.

2. WEN 56225i – Budget-friendly for a small/medium bounce house

The Westinghouse iGen2500 is still reasonably priced for its power level but this WEN 56225i is even more budget-friendly.

WEN 56225i

One thing you do want to keep in mind is that the 2250 starting watts and 1800 running watts are not always enough for bigger bounce houses.

Additionally, the WEN 56225i likely does not offer enough power to run a refrigerator or electric grill on top of the small/medium bounce house.

People who set up bounce house parties as a company also want to know this generator only has 90 days commercial warranty.

Pros

  • WEN 56225i offers 2250 starting watts, 1800 running watts, 15 amps, and 120 volts
  • Parallel capability
  • Relatively low noise levels of 53 dBA
  • Nice run time of 6 hours at 50% load
  • Less than 1.2% THD
  • Light weight of 48.5 lb (22 kg)
  • Relatively positive customer reviews
  • 2 years limited residential and 90 days limited commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • Relatively short commercial warranty
  • Uses a lot of oil

While you do want to know about the smaller potential downsides above, the WEN 56225i is still a great option if you only want to run a small or medium inflatable.

This generator does not offer in-depth tracking but the upside is that operating the machine is relatively straightforward.

Additionally, the light weight of 48.5 pounds means you can easily get the generator in and out of position.

As the many happy customers can confirm, being budget-friendly does not necessarily mean being bad.

The WEN 56225i is another solid option if it offers enough power for your needs.

3. Westinghouse iGen4500 – Best generator for bounce house parties

All the generators on this list can power at least one small or medium bounce house but you may want more than this.

If this is the case, you will likely prefer the Westinghouse iGen4500.

Westinghouse iGen4500

Besides a bounce house, this generator can run something like an energy-friendly refrigerator or two, an electric grill, or a microwave oven.

In simpler words, this 4500 watt generator allows you to take the party and/or the barbecue after to the next level.

Pros

  • Westinghouse iGen4500 offers 4500 starting watts, 3700 running watts, 30 amps, and 120 volts
  • Parallel capability
  • Relatively low noise levels of 52 dBA
  • Long run time of 18 hours at 25% load
  • Less than 3% THD
  • A lot of performance tracking metrics
  • Optional CO sensor
  • Weight of 104.7 lbs (47.5 kg)
  • Relatively positive customer reviews
  • 3 years limited residential and 1 year limited commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • Navigating bumpy terrain can be inconvenient
  • Some customers find changing the oil challenging

Two small downsides to keep in mind are that the Westinghouse iGen4500 is somewhat heavier and that the wheels are a bit small for bumpy terrain.

That means you may need some help setting up the bounce house generator before the fun can begin.

Once you take care of this, the long run time of 18 hours at 25% load makes it so you won’t have to do that many refuel sessions throughout the day.

And on top of the other solid features, there is a Westinghouse iGen4500 version with a CO sensor to add an extra layer of safety.

4. WEN DF250i – Best dual fuel

Portable generators like the other models on the list are often gasoline-only. However, there are also dual fuel models like the WEN DF250i that can run on propane.

This is relevant because gasoline can gum up generator carburetors if you only use them occasionally and don’t take the right precautions.

WEN DF250i

On the flip side, propane does not involve as much maintenance. If you only want to set up the bounce house every once in a while, this could save you some effort.

Additionally, by using a somewhat bigger propane tank you can avoid or at least reduce refueling sessions throughout the day.

Pros

  • WEN DF250i offers 2500 starting watts, 2000 running watts, 16.6 amps, and 120 volts (gasoline)
  • Dual fuel so can also run on propane (LPG)
  • Relatively low noise levels of 52 dBA
  • Good run time of 6 hours at 50% load
  • Less than 1.2% THD
  • Light weight of 48.5 lb (22 kg)
  • 2 years limited residential and 90 days limited commercial warranties
  • Budget-friendly

Cons

  • Relatively short commercial warranty
  • Not that many customers for this specific model

Something to note is that the WEN DF250i specifically does not have that many customers yet.

However, while there are exceptions, customers tend to be happy overall with portable generators from WEN.

People with a bounce house or inflatables rental business or something similar want to keep the 90 days limited commercial warranty in mind too.

That being said, if you like the potential benefits of using a propane generator for your bounce house, the WEN DF250i can be the best option for you.

5. Honda EU2200i – Most reliable and quietest medium bounce house generator

The Honda EU2200i is a portable generator that is well-known for its reliability, quiet operation, and unfortunately price.

If you only plan to power a small or medium bounce house blower, this is likely not the best generator for you.

Honda EU2200i

However, the Honda EU2200i is worth briefly mentioning for people who also want to use their generator as a source of backup power for things like a fridge.

In situations like this where you really need your generator to work, the extra reliability can be worth the extra investment.

Pros

  • Honda EU2200i offers 2200 starting watts, 1800 running watts, 18.3 amps, and 120 volts.
  • Parallel capability
  • Quietest bounce house generator with 48 to 57 dBA (at 25% to 100% load)
  • Run time of 8.1 hours at 25% load
  • Less than 3% THD
  • Honda My Generator app connectivity
  • CO sensor
  • Honda generator brand reputation
  • Light weight of 47.4 lb (21.5 kg)
  • 3 years limited residential and 12 months limited commercial warranties
  • Very positive customer reviews
  • A lot of customers

Cons

  • Expensive for a bounce house generator

The Honda EU2200i is also just a quiet small generator. This can make your bounce house party more pleasant (although the blower will typically make more noise anyway).

Another detail that positively stands out is the ability to track generator performance through the app from Honda.

This allows you to see how much more the Honda EU2200i can power besides the bounce house and even enables you to stop the portable generator remotely.

Similar to some of the previous models, the CO sensor of the Honda EU2200i can offer some peace of mind too.

In short, people who want a bounce house generator with extra durability and reliability for other purposes could theoretically consider investing more in the Honda EU2200i.

FAQ

What size generator is needed for a bounce house?

What size generator is needed for a bounce house depends on the size of the inflatable (and the blower).

For example, to run a 1 HP blower, a 1000 running watt, typically 1200 peak watt or more, generator should be big enough.

Something like a 1.5 HP blower for bounce houses will typically require around 1200 running watts which means you will need a 1500 peak watt or stronger generator.

To run a big 2 HP blower, you want around 2000 running watts. In turn, a 2500 peak watt generator should be enough for your bounce house.

If you want to run multiple bounce houses or other electronics like an electric grill, refrigerator, or ice cream machine, you will need a bigger generator too.

How many watts does it take to run a bouncy castle?

It typically takes around 1000 running watts to run a small bouncy castle and around 1200 running watts to power a medium bouncy castle.

How many amps does a bounce house need?

Small to medium bounce house blowers typically need fewer than 10 amps.

Even bigger blowers only need around 15 amps or less to function.

Our top pick

You may still be unsure about what bounce house generator would be the best for your situation.

In situations like this, our top pick, the Westinghouse iGen2500 is often a good choice.
