RVers who want to operate their AC without access to shore power will require a sufficient generator. Finding the best generator for RV air conditioner units, on the other hand, has become increasingly difficult. The sheer amount of alternatives available has made the procedure extremely difficult.

Our buying guide, on the other hand, aims to clarify these difficulties with an easy-to-follow layout. If you persist with it, those unpleasant sensations will go and the procedure will become completely simple. You’ll then have the ideal generator for effectively running an AC unit and other aboard equipment.

Let’s start with product reviews of my top five picks for the best dual-fuel inverter generator for RV.

How many watts do I need to run a Camper AC?

The usual air conditioning unit in a medium-sized camper requires between 1,900 and 3,500 watts to start and 600 to 1,700 watts to operate. The startup quantity will consume the greatest power, but the operating amount will be significantly lower, accounting for around half of the initial power usage.

How Many Amps Does An RV Ac Use?

The average air conditioner requires 12-16 amps of power. The actual value will be affected by the mode in which it is functioning. An air conditioner in an RV can consume up to 13 amps of power.

How Long Can You Run An RV Air Conditioner?

In general, you should be able to run your RV for roughly 8 hours on two gallons of petrol. So, if you have a generator that can carry 6 gallons of gas and you are not using it for anything else, the RV air conditioner will be able to operate 24 hours a day.

Will A 3500 Watt Generator Run An Rv Air Conditioner?

Yes, a 3500-watt will power your RV! It can power nearly any size RV. However, it is dependent on how many appliances you wish to operate at the same time.

Best Generators for RV Air Conditioner Buying Guide

Finding a generator to power RV AC units would need a thorough understanding of several elements. Everything you need to know about these gadgets is included in our buying guide. You should have no trouble finding a suitable solution to it.


If you prioritize utilizing an AC while traveling, it’s critical to find a generator with adequate power to power it. The wattage of an RV generator tells purchasers if it can power their air conditioner.

When it comes to picking a generator for their RV, most RV owners will prioritize this element. After all, your RV’s AC power requirements will be the highest of all of your appliances. It even outperforms bigger equipment such as refrigerators and electric heaters.

As a result, an RVer must understand how many watts their air conditioner consumes when it is turned on and off. You should be aware that its running wattage will be lower than its start-up wattage. You should start with the AC’s start-up wattage and choose a generator that can handle it.

Portability and Size

As you might expect, portable generators provide a level of convenience that other varieties do not. Those looking to purchase a portable generator will want one with handles and wheels. The majority of alternatives will include these characteristics, however, some lower-quality options will not. Their presence will make transferring the gadget far easier than you would anticipate.

However, when selecting the appropriate model, it is also critical to examine their total size. You’ll want a small, lightweight choice that will easily fit into your RV.

Best Generators for RV Air Conditioner Buying Guide


Every generator has a maximum fuel capacity. Look at each model’s fuel economy if you want a vehicle that doesn’t require much refueling. It’s an important consideration because the costs of fuel, gas, and propane are always fluctuating.

As a result, you don’t want a generator that consumes a lot of gasoline. You want a vehicle that is known for being fuel-efficient and cost-effective. I’d suggest reading the customer reviews to get a sense of how effective each option is.

Noise Level

Generator noise is a regular annoyance at campgrounds. I can’t tell you how many times a neighbor’s generator kept me awake at night. I’m sure you don’t want to be the source of another person’s restless night.

As a result, the noise level of a generator should factor into your ultimate selection. To guarantee that the generator is not a nuisance, it is essential to opt for the quietest generator for RV use. It’s another area where user feedback will be quite useful.

Type of Fuel

As I previously stated, the price and availability of fuels are always changing. That’s why most RVers look for generators that can run on a variety of fuels. To provide the desired adaptability, these alternatives will include a dual-fuel option.

However, some RV owners may choose a single-fuel generator. In any event, you’ll need to choose a model that completely matches your specific fuel requirements.
