What Size Generator Do I Need to Run RV Air Conditioner?

Now that you are all clear about the capacity of an RV generator, let’s proceed further and bring to light some other important factors related to buying the best generator for RV AC. Firstly, there’s this discussion on what size generator you need to run an RV air conditioner; and secondly, it’s about the important points that need to be kept in mind while making a purchase.

So starting with the first point of discussion here’s everything you need to know with reference to the size of an RV generator:

There are a lot of sizes available for ACs as well. Depending on the size range of your RV’s AC, you can measure the appropriate size for the generator that’d keep it running. In addition to what has been said, it’s not only about the air conditioner, but numerous other electrical appliances are inevitable to use in an RV. So you have to consider their power requirements as well.

With that said, we have sorted out the following list that contains the major size ranges available in AC units. Let’s have a look at it:

Firstly, some basic AC units have a starting watt rate of up to 4000 watts or near 4500W. So in that case, the generator range with 4500 peak watt capacity would be the best size to run RV AC.

Next up is another size range of generators that can easily accommodate a medium-sized generator, alongside other electrical needs such as lights, stoves, kitchen appliances, etc. These generators have a peak watt capacity of around 6000 watts. So a 50-amp RV generator would do the best in this regard.

In order to calculate what size generator you need to have with your 50 Amp RV, there’s this simple formula to be used:

Volts x Amperage = Watts

Multiplying the number of volts with the amperage power of your RV can get you the exact value required to depict the number of watts necessary to power the particular RV. So in the case of a 50-amp RV, it goes like this:

120 (Volts) x 50 (Amperage) = 6,000 watts

Last but not least, there’s the size range commonly available on the market is that of 10,000 as the starting watt capacity. This might get a bit extra for RV use, but the power supply with such units is exceptionally high.

What are the Things have to Consider While Buying the Best Generator for RV AC

There are several factors that you need to keep in mind while buying one of the best RV generators for running an air conditioner. Once you have sorted out the right size type of the power unit, the next logical step should be to figure out a few other tech specs in order to have one durable backup power source.

So without further ado, let’s get down to exploring the important factors that are crucial to be kept in mind while you are making a purchase. Here we go:

Wattage Capacity

Just to have a recap of what’s been mentioned earlier, the first and foremost thing that you should consider while spending your money on a generator, is its wattage capacity. Prior to that, make sure to keep in mind the starting wattage rate of the AC unit or any other larger electrical appliance in your RV.

Having said that, you can easily calculate the starting wattage of the generator you want to buy by simply multiplying the number of volts by the amperage power. A generator having more than 4000 peak watts would be suitable to run any basic AC unit.

Fuel Type

The second most important thing is the type of fuel that your generator runs on. In order to have a power unit that could provide a consistent power backup all day long, you can opt for a gasoline fuel type. One of the main reasons to go for this is that it is easily available anywhere you go.

On the flip side, your RV generator will give exceptional fuel efficiency with diesel as the engine runs perfectly on diesel. Nevertheless, this is not a cost-effective option to go for, so better to keep that in mind as well.

Some technically advanced generators have dual-fuel technology. You can consider those as well since they give the option of switching between fuel types to attain efficiency.

Parallel Connectivity

Another thing that is optional, yet very useful is the parallel capacity of a generator. You can have your generator connected with another unit of a similar range, and double the power effectively.


Last but not least, make sure that you keep an eye on the price tags of the power units you’re shortlisting. This is important to make a price comparison at the end so that you can buy a more cost-effective generator for your RV AC.

Frequently-Asked Related Questions (FAQs)

1. How many watts of the generator to run the RV air conditioner?

There are several options that you can choose from while you are searching for RV generators to run air conditioners. From having a medium-sized power unit that can easily start up for operation, to a giant that could accommodate even the largest AC units, all you need to consider is the starting watt capacity of your RV AC. That said, typically generator sizes from 4000 W to 6000W of peak watt capacity are used by RVers.

2. What size generator for an RV air conditioner?

There are different size ranges available for RV air conditioners. You can choose from a basic power unit to a mediocre generator, or even have the most powerful generator with extensive wattage capacity.

This all depends on the number of starting watts of the AC unit that is installed in your RV. However, from a general perspective, RVs usually have a basic air conditioner peak watt capacity of up to 4500W. Or else, it gets higher till 6000W. This is the size range for RV generators typically.

3. What size generator do I need for a 15000 BTU RV air conditioner?

The size of any generator is measured through the starting wattage capacity, as it needs that much power to get going. Once started, the wattage required to keep running gets reduced to a good fraction. Now that was something we already knew!

Getting to the main point of discussion, the generator size you need to run a 15000 BTU RV air conditioner is the one with up to 3500W of peak watt capacity. This means that the running wattage provided by this would be equal to 1500 watts generally.

4. What size generator for a 30 amp RV air conditioner?

In order to calculate what size generator you need to have with your 30 Amp RV, there’s this simple formula to be used: Volts x Amperage = Watts

Multiplying the number of volts with the amperage power of your RV can get you the exact value required to depict the number of watts necessary to power the particular RV. So in the case of a 30 amp RV, it goes like this:

120 (Volts) x 30 (Amperage) = 3600 watts

Now the obtained answer is the peak capacity of a 30 amp RV – as a generator providing more watts than 3600 would not be running on this vehicle. So you are better off with a generator size ranging between 3000 watts to 3600 watts.

Final Thoughts

This brings us to the end of our review on the best generator to run an RV air conditioner in the year 2022.
