When it’s blistering hot, you don’t want to leave your air conditioning to chance. Having the best generator for RV air conditioner needs is a must.

Just because you go to an RV park with hookups doesn’t mean everything will go smoothly. You never know when their electricity will go down or when you will have some other problem.

While we were out camping in New York once, it was so hot and miserable and everyone had electricity except for one row of very unhappy people—which happened to include us. However, we had a generator so we chilled out pretty quickly.

My Pick for Best Generator for RV Air Conditioner

You don’t have to wait until the end of the article to learn about which generator I think is best for powering your RV air conditioner. Enjoy.

We had been camping for a while before we sprung for this Champion 3,400 watt dual fuel generator. I think we paid a little bit less than $2,000 for it when we bought it and it was worth every penny.

I’d never used a generator before but I did know we wanted an inverter generator so we could plug stuff into it and so it wouldn’t be so loud while it was powering us.

The electric start made a big difference because I’m weak and don’t do very well with the pull string. My husband can do it but he’s got body aches from the military so it’s best he doesn’t.

This Champion generator is pretty quiet at only 59 dB and we can have a conversation without having to yell even if it’s only a couple of feet away. That makes it nice when you need to use it and you’re hanging out with friends.

This generator comes with a 3-year limited warranty and lifetime support from experts if you do have any technical problems with it.

How Much Power Does It Take a Generator to Run an RV Air Conditioner?

Most RVers would agree with me when I say that being able to run the air conditioner in their RV is probably the most important thing they want. You can’t enjoy anything if you feel like you’re melting. This is why it’s key to find the best generator for RV air conditioner.

RV air conditioners do take a lot of power, so you will need plenty of juice to keep them running.

The average RV generator takes anywhere from 2,000 to 4,000 watts to get going and to keep you and your crew cool. Keep in mind that some RVs have more than one air conditioner so you might need even more power than that.

What to Look for When Buying a Generator for Your RV Air Conditioner

The main things you need to think about when you’re buying a new generator are:

  • Watts
  • Fuel efficiency
  • Ability to tote it around
  • How loud it is
  • Type of fuel it uses
  • How much money it costs

When you put together your budget, you might go a little too low if you don’t check out some of the prices. Generators are in high demand, so they are a little more money than you might expect, so take a look around before you set your budget.

When it comes to watts, keep in mind that it’s better to have more than you need than be sitting at your campsite wishing your generator could power your RV air conditioner.

We also like the dual fuel option so we can always have fuel – even when one type or the other isn’t easily accessible.

You should also make sure you can get the generator in and out of your vehicle when it’s time to use it. Having a generator with a wheel kit can be a back saver.

More Options When it Comes to the Best Generator for RV Air Conditioner

2. YAMAHA EF2000iSv2, 1600 Running Watts/2000 Starting Watts, Gas Powered Portable Inverter

One of the big things this generator has going for it is the name brand of Yamaha. It’s a great company and they stand behind their products.

People know the engines they make will stand up to a lot and you want reliable power when you need air conditioning in your RV.

The Yamaha EF2000iSv2 is another quiet option and at 25% load, it only puts out 51 dB and could even be quieter depending on how far away you are. That’s pretty quiet for a generator and won’t make you feel like it’s trying to take over the conversation.

You can get about 10 hours of run-time from this generator if you’ve only got it at 50% load. If you’re running the RV air conditioning on it then you might get a little less time before you need to refuel.

It’s as quiet as a mouse at 52dB at 25% and still gives you a good bit of power for your money. You may only be able to run your small RV air conditioner off of this one since it only has 1,800 running watts.

The fuel efficiency on this model is good and can last for around 12 hours on 1.2 gallons the tank holds if you aren’t maxing it out. When running your RV air conditioner, it’s likely you’ll have less time.

Briggs & Stratton offers a 2-year limited warranty so you can rest easy about your purchase.
