This newer model from Champion is a quiet generator for RV use, thanks to its repositioned fans and other design specs. It produces about half the noise as the original Champion 3500-watt model. Even so, its open frame still makes it louder than many of the fully enclosed generators. 

It’s rated at 64dBa, which is not much louder than a human conversation at 23 feet.

At 4,000 starting watts and 3,500 average running wattage, it can easily handle air conditioning units and other large appliances like fridges.

To get going, simply pull the cord. To the right is the control panel with useful modes like Eco and LED lights to warn of potential overloading. 

You get 12V, 120V, two 120V DC outlets, and USB support. One tank of fuel produces an impressive 17 hours of power at 25% capacity.

How To Choose The Right Generator for an RV Air Conditioner?

Choosing the best generator for RV appliances and ACs has a lot to do with how often you use your electronics and the climate. Here’s what you should consider.


Well-made portable AC generators will always cost you a few hundred dollars. Price is usually reflective of its power in wattage, but other features play a role too. You can expect to spend from as low as $400 to well over $1,000. The 2200W Honda EU2200i is the most expensive on our list. 


Air conditioning units are one of the more power-hungry appliances you’ll find in a recreational vehicle. Therefore, you need to look for a generator with sufficient capacity to meet the AC’s power needs.

Generators express power in wattage, and anything from 2000W and above can accommodate an AC unit. However, particularly powerful ACs or RVs with numerous appliances may require a model with a range of 3400W to 4000W or more. 


A generator’s outlets are one of the most important factors in determining the type and number of devices that can be connected. Most commonly found are 120V household outlets that accommodate most items, from hairdryers to TVs. 

Some air conditioners require a 3-prong AMP outlet, which most generators have. Just make a note of the amperage and voltage numbers. The generator needs to be higher than the AC. For example, a 14A, 100V air conditioner will work with a 30A, 120V amp outlet.

It’s also common to get a 12V DC outlet, similar to ones found in car consoles, along with a USB port to charge your devices.   

Parallel Generators

If you are a heavy user of power and need to run an AC unit alongside many other devices, it’s possible to operate two generators in parallel. This is a simple cable that connects two of the same models together.

Not only does this give you more power, but it’s also more energy-efficient. 


You don’t want a generator with too many controls, as such may become confusing. You can expect an on-off switch for electric start generators, a pull cord to start up the traditional way, and possibly a switch for eco/power-saving mode. There should also be safety indicator lights.

Some models will have a display giving out fuel and power readings.

Furthermore, it’s becoming increasingly common for generators to have Bluetooth and a mobile app, so you can check in on performance and even turn the generator off.


The amount of noise a generator creates is a primary consideration for two reasons. First off, if you and your family are sleeping in an RV, you most likely prefer not to be disturbed by loud generator noise. Secondly, if you require electricity within a populated area, there’s a good chance others will not appreciate a noisy one.

Makers of the quietest generators for RV owners tend to have Eco or low power modes and are generally less powerful. 

Most generator manufacturers will specify a decibel rating, so you know exactly how loud they are.   


If you want a quiet portable generator for RV power, you’re going to get the best results with one that is enclosed. This simply means it encases all noisy components and mechanics in plastic or another material.

Furthermore, accidental burns and injuries are preventable with the generator fully enclosed. 


If traveling about, chances are you don’t want a cumbersome generator. You should expect a quality RV generator to come with carrying handles. Moreover, the larger ones will have wheels to avoid any heavy lifting. 

Handle designs often fold away for more compact storage, while others are hard-molded for lasting durability.

Fuel Type

RV generators use gasoline as their primary fuel, while some use propane and diesel. Certain model designs work with more than one fuel type. For ease of start, many have an electric start instead of pulling the recoil cord.  

Fuel Life

Fuel efficiency determines how long a generator operates at a certain percentage of power use. Manufacturers usually express this as hours per load - for example, 10 hours at a quarter load. The load refers to the power consumption, not the amount of fuel in the tank. However, the measure might also state how many hours of use per tank, half tank, etc.


Size matters when it comes to power and sound. The lightweight generators RV owners tend to choose are compact, portable, and quiet. However, they often lack sufficient power capability to run an AC unit along with other appliances.  

On the flip side, large generators tend to be more powerful but less portable. They’re also typically louder. 

Wrap Up

Picking the right generator to run an RV AC unit can potentially be a bigger headache than first anticipated. Fortunately, our top nine picks shed light on many available options to help guide your decision.
