How to choose a good generator for RV air conditioner? (buying guide)

Best Generators For RV Air Conditioner

Power Output

This is the most vital feature to help you find out a suitable generator. If it’s just to operate your RV air conditioner, a 2500W to 3000W unit is a good go-to.

But in most cases, we know that you’ll also use it to run some other RV appliances, such as refrigerator, fan, and lighting. In this case, you should consider a higher power model. The number depends on how much power output you need.

To determine this indicator, list out the peak wattages and running wattages of all RV appliances (including your AC). Then, make a sum. These two numbers are what you should remember when considering the power output of a generator.

A suitable generator should feature higher surge wattage and running wattage than such number data. Don’t go any lower!


The runtime of a generator depends on how long you intend to use it to run your RV air conditioner as well as other appliances. The longer the usage, the longer the runtime.

Also notice that longer runtime needs more fuel to consume, meaning a bigger tank and therefore, your generator will be heavier and bulkier. If your real need isn’t that much, just go for 1.5 to 2 gallons of a fuel tank.

The largest in this list is the Pulsar PG4000iSR with over 3 gallons’ fuel tanks.

Noise level

It’s not always true that the more powerful the generator, the noisier. Inverter units are a shining example of that. They provide powerful motor while keeping noise level at the low range to avoid bothersomely.

The only downside of this generator type is its costly price.

Or, you can go for the traditional generators but only the one featuring noise absorption features to decrease its noise pollution while running.

The pleasant noise level of an RV generator should be within 50 to 65 dB.

Who makes the best generators for RV air conditioner?

Best Generators For RV Air Conditioner


Three things that make Champion Power Equipment becomes one of the most popular American company are their products’ quality, outstanding design, and caring customer service.

Briggs & Stratton

This is one of the most reliable brands lately thanks to the versatile and durable built of their generators. They’re known for a favorite choice of many RV-ers with a tight budget who can’t afford such expensive models from Honda or Yamaha.


Founded in 1951, WEN has been now the worldwide brand that gives a perfect compromise of affordability and quality.

Produce over 46 thousand generator models in different sizes over the world, it’s possible to find at least one Honda unit fitting intensively your needs and requirements.


Pulsar might be the youngest brand in this list but it strikes back with the fastest growth. Their products focus on enhancing performance while keeping modest quality, making them one of the best portable generators on the market.


Best Generators For RV Air Conditioner

What size generator do I need for a 13500/15000 BTU air conditioner?

Like refrigerators, air conditioners eat up more power to start than when it’s running. Accordingly, for a 13,500 BTU AC, the surge wattages should be 2800 to 3000W while the running wattages are within 1500 to 2000W.

With a 15,000 BTU AC, the surge wattages are 3300 to 3500W and the running wattages should be somewhere between 1300 and 1800W.

Will a 2000 watt generator run my RV AC?

With a 2000W generator, it can run an RV air conditioner for maximum 7000 BTU (featuring an average starting wattage of 1800W and running wattage of 650W)

How many hours does an RV generator last?

The runtime of an RV generator depends on the fuel tank capacity and energy efficiency rating of that unit. In general, it’s within 8 to 20 hours.

How much fuel does an RV generator use?

This is based on the fuel type that your generator is using, how energy efficiency of it, and how much you use the unit. There are three types of fuel – gas, diesel, and propane.

If you only calculate the needed fuel amount due to the fuel type, the diesel will give the highest efficiency – 75 gallons for every 2 loads’ air conditioner. Next is propane!

A standard 5000W gas generator eats up 18 gallons in every 24 hours of use and the propane needs 3.44 gallons/hour to generate 20 kWh or 6.1 gallons/hour for 35 kWh.

Is it cheaper to run a generator on propane or gas?

While a propane generator consumes around 3.44 gallons/hour for 20 kWh, a gas unit just needs 0.75 gallons/hour to generate a similar or even higher amount of power.

Therefore, a gas generator runs cheaper.


In a nutshell, the secrets to quickly determine the best generators for RV air conditioner is considering your required power output and power needs. That said though, getting know the running wattages and peak wattages of your RV air conditioner is one of the first tasks to do.

We hope this article has been helpful, especially the rounded-up list. Thanks for reading!
