5 Best generators for RV air conditioners reviewed

If you know your power needs and fuel preferences, the list of top picks and the performance table can be enough to choose an RV AC generator.

At the same time, you may still find it easier to make a decision after checking out the in-depth reviews below.

1. WEN 56380i 3800 – Best generator for 15000 BTU RV air conditioners

WEN 56380i 3800

Our top pick for the best generator for 15k BTU RV air conditioners is the WEN 56380i 3800 thanks to its suited power level, solid features, good reliability, and budget-friendly price.

Additionally, because a 15000 BTU RV AC only requires around 1500 watts after the initial start, there is power for other devices too.

More specifically, the WEN 56380i 3800 should be strong enough to run things like an RV refrigerator, microwave, or electric grill too.

The one downside of this generator is that it can be inconvenient to roll over bumpy RV camping terrain due to its small wheels.

Pros

  • WEN 56380i offers 3800 starting watts, 3400 running watts, 30 amps, and 120 volts
  • TT-30R outlet makes it easier to connect to an RV
  • Parallel capability
  • Relatively low noise levels of 57 dBA
  • Good run time of 8.5 hours at 50% load
  • Nice fuel efficiency
  • Less than 1.2% THD
  • Electric start
  • Weight of 99.2 lb (45 kg)
  • Very positive customer reviews
  • 2 years limited residential and 90 days limited commercial warranties
  • A lot of customers

Cons

  • Can be challenging to move over bumpy terrain

That being said, since the weight of 99.2 lb (45 kg) is still reasonable, you and your RV buddies should be able to get the WEN 56380i 3800 in position anyway.

After that, you can enjoy the clean power for a nice amount of time and at reasonable noise levels.

The 8.5 hours run time at 50% load and noise levels of 57 dBA should be good enough to power your RV air conditioner throughout the night.

Something that really stands out in the WEN 56380i 3800 too is the budget-friendly price at which you get all this power and quality.

2. Westinghouse iGen4500DF – Best dual fuel for 15K BTU RV air conditioners

Westinghouse iGen4500DF

Gasoline tends to be the most popular fuel choice but if you want to use propane too, the Westinghouse iGen4500DF can be worth the investment.

The Westinghouse iGen4500DF is a nice amount stronger than the WEN 56380i when running on gasoline but keep in mind that using propane offers fewer watts.

On the flip side, one of the benefits of propane is that it typically stores longer than gasoline.

This makes it more convenient to stay prepared for any unexpected RV trips or boondocking sessions.

Gasoline stores require just a bit more time and attention to keep them ready to use.

Pros

  • Westinghouse iGen4500DF offers 4500 starting watts, 3700 running watts, 30 amps, and 120 volts (gasoline)
  • TT-30R outlet makes it easier to connect to an RV
  • Parallel capability
  • Dual fuel feature allows you to run on propane (LPG) too
  • 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)
  • Very positive customer reviews
  • 3 years limited residential and 1 year limited commercial warranties
  • A lot of customers

Cons

  • Some customers find changing the oil challenging
  • Can be challenging to move over bumpy terrain

Within the category of dual fuel generators for 15k BTU air conditioners, the Westinghouse iGen4500DF stands out in details like its quiet operation.

With a noise level rating of 52 dBA you and your RV neighbors should not mind this RV air conditioner power source too much.

And if you do decide to run on gasoline anyway, the long run time of 18 hours at 25% load makes it so you can enjoy your power without too many refueling sessions.

In short, if you want to run your 15000 BTU air conditioner and a few other small devices on propane, the Westinghouse iGen4500DF is likely the right choice.

3. Champion 201067 – Best generator for an RV AC and much more

The previous generators could already handle some extra devices on top of the mentioned RV ACs but if you want to take this one step further, the Champion 201067 is likely better.

With 9000 starting watts, 7250 running watts, 50 amps, and 240 volts, you will often be able to run all the devices in your RV.

This sounds and is great but you do want to keep the louder noise levels of 72 dBA in mind.

The Champion 201067 is not always quiet enough for RV park guidelines and running an RV AC overnight may mess with your sleep.

Pros

  • Champion 201067 offers 9000 starting watts, 7250 running watts, 50 amps, and 240 volts
  • 14-50R outlet makes it easier to connect to certain RVs
  • Run time of 10.5 hours at 25% load
  • Less than 3% THD
  • Electric start
  • CO sensor
  • Four GFCI outlets
  • Weight of 152.2 lb (69 kg)
  • Very positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers

Cons

  • Noise levels of 72 dBA can be too loud for the RV park or camping guidelines
  • Run time is not the most impressive

It is also worth noting that the 10.5 hours at 25% load is not that impressive compared to many other RV air conditioner generators.

At the same time, with all that power, the run time of the Champion 201067 9000 should still be enough.

Additionally, the reliability of the Champion 201067 9000 all the positive customer reviews imply positively stands out.

The electric start may not be the most unique feature but it does make your RV life more convenient.

And if you do find the noise levels of the Champion 201067 9000 a bit too high, you could consider investing more in the quieter Champion 201175 8500.

4. Champion 201001 – Best generator for 18000 BTU RV air conditioners

18000 BTU RV air conditioners are not the most popular option but they are common enough to deserve their own generator recommendations.

The 5500 starting watts and 4000 running watts of the Champion 201001 can also just be useful if you want to power many other devices in your RV.

On top of this nice amount of power, the Champion 201001 offers solid features and good reliability too.

For example, if you have the generator set up, the remote start of the Champion 201001 allows you to start powering your air conditioner from the comfort of your RV.

This means you don’t have to go out at night or in suboptimal weather conditions (if your generator is protected enough).

Pros

  • Champion 201001 offers 5500 starting watts, 4000 running watts, 30 amps, and 120 volts
  • TT-30R outlet makes it easier to connect to an RV
  • Parallel capability
  • Relatively low noise levels of 61 dBA
  • Good run time of 20 hours at 25% load
  • Good fuel efficiency
  • Less than 3% THD
  • Weight of 119 lb (54 kg)
  • Has electric and remote start
  • Very positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers

Cons

  • Moving the generator over uneven terrain can be challenging

Additionally, with the reasonable noise levels of 61 dBA (more or less as loud as a regular conversation), the sound should not disturb you and your neighbors too much.

In combination with the long run time of 20 hours at 25% load, the Champion 201001 can be great for running an RV air conditioner throughout the night.

One small downside is that this inverter generator can be somewhat challenging to move over bumpy terrain.

That being said, if you have an 18000 BTU RV AC or the 5500 peak watts just sound good, the Champion 201001 can be a great investment.

5. Champion 201003 – Best dual fuel generator for 18000 BTU RV air conditioners

The Champion 201003 is very similar to the previous RV AC generator but without a remote start, with slightly more technical issues, with a dual fuel feature, and with a slightly higher price.

In simpler words, if you want a propane-compatible generator that can deal with an 18k BTU RV AC and a few more devices, this could be the right option for you.

The slightly higher rate of technical issues is not ideal but is not unusual for the dual fuel versions of generators either.

It is also worth mentioning again that running the Champion 201003 on propane will offer fewer running watts (3600 running watts).

Pros

  • Champion 201003 offers 5500 starting watts, 4000 running watts, 30 amps, and 120 volts (gasoline)
  • TT-30R outlet makes it easier to connect to an RV
  • Parallel capability
  • Dual fuel feature allows you to run on propane (LPG) too
  • Relatively low noise levels of 61 dBA
  • Good run time of 20 hours at 25% load (gasoline)
  • Good gasoline fuel efficiency
  • Less than 3% THD
  • Weight of 118 lb (53.5 kg)
  • Has electric start
  • 3 years limited residential and 270 days limited commercial warranties

Cons

  • Moving the generator over uneven terrain can be challenging
  • A few very exceptional technical issues

And when you do decide to use gasoline, you still get the same good fuel efficiency.

In simpler words, the Champion 201003 is able to get a nice amount of kWh out of a gallon of fuel.

As mentioned in the previous option, the Champion 201003 offers a nice run time, quiet noise levels, and an electric start too.

So this RV air conditioner generator will not be for everyone.

However, if you have an 18k BTU RV AC or just want to run many devices on propane, the Champion 201003 can be a good investment.
