Buying Guide

Finding the best generator for RV air conditioner is challenging as people don’t buy such appliances regularly. So, before making any decision, you need to consider many important factors. If you consider these factors, you can get the perfect generator that meets your need.


The size and weight matter when you have to use an RV, so the generator must be light in weight and compact in design. Portable generators are the best types of generators. It is because you can use it anywhere you want to use it. Further, the generators we reviewed are lightweight that promote portability.

Many generators have wheels and handle that offer easy and quick movement. You can use such generators in an RV and in the home. Additionally, such generators are suitable for camping as well.

Fuel efficiency

There is constant fluctuation in the price of gasoline, diesel, and propane. And usually, the generators are not fueled efficiently; they consume much fuel. But you don’t need to worry about fuel consumption, and the advanced generators are fuel-efficient. Besides, we choose the fuel-efficient model and have ‘Eco Mode.’

A generator that consumes lots of fuel is not what you need. The fuel efficiency of some generators differs from that of others. If you are concerned about how much fuel you will need in the woods, make sure to pack plenty of extras. So, make sure you consider fuel efficiency.


According to us, one of the most important factors needs your attention. Before buying, you have to decide whether you need a generator only to run AC. If you need a generator only to run AC, then the generator with 2000 to 3000 wattage is enough.

On the other hand, if you have to run a refrigerator, oven, or other heavy appliances in your RV, make sure the generator is powerful enough. For this, we recommend you choose a generator that output wattage is above 4000.

On our list, the wattage ranges from 3500 to 6600. So, choose according to your need.

Fuel type

We recommend you choose a generator that has dual fuel sources as we all know the prices of fuel increases day by day in the whole world. And sometimes we have to face a shortage as well, so if the generator has only one fuel type, you maybe feel difficulty.

The advanced generators run on gas, propane, or diesel. So, make sure you’re choosing a model that has a dual fuel source.

Noise level

Usually, the generators consider noisy, but now it is not true. If the generator is noisy, it is not possible for you to run it for a long time as it bothers you and your neighbors as well. The advanced generators come with the latest technology that makes them quiet, so they will not bother you. So, you can run your generator for a long time.

The noise level of the generators, as mentioned earlier, ranges from 45 to 60 decibels, which ensures it works silently. People often neglect this factor but it needs your consideration. So, make sure you choose the model that has less noise level.


Last but not least, the price is one of the most important factors. It is true that you get more value for your money the more you pay. In addition, the prices of the generators depend on the company, features, model, power, and size.

If you have to run your AC in your RV on a generator, then the price is a bit high as compared to other generators. It would be best if you have a powerful generator to run AC, and the price ranges from $500 to $1000.
