Depending on the size of your rig, be it a travel trailer or fifth wheel, choosing the best portable RV generator depends on what you want to power.

Price and brand loyalty play a part in the deciding factor as well. So let’s dive into it; the following are the best portable generators for RVs.

What Is a Portable RV Generator?

A portable generator burns fuel to power an engine that runs an onboard alternator to create electricity. Many generators can power residential appliances or even an entire recreational vehicle.

Generators can produce a limited amount of power for an extended period. You measure the energy output of a generator in watts. The more watts a generator is rated for, the more options you’ll have in terms of power.

Portable generators are incredibly convenient and designed for mobility. That lets them create generous amounts of power and makes them popular among RVers.

You’ll have power for as long as you can keep fuel in the generator’s tank!

What Size Generator Do I Need for My RV?

Consider your power needs when figuring out what size of generator you need. A 3500W generator is an excellent choice for running several items in your RV. It’s comparable to using a 50-amp RV on a 30-amp power service. If you use too much power, the generator will likely shut down to avoid potential damage.

Some RVers opt for purchasing a pair of 2000W generators and daisy-chaining them together. A 2000W generator is considerably lighter and easier to move around. When daisy-chained together, two 2000W generators can produce a tremendous amount of power. 

What to Look for in an RV Generator

You may have thought about getting a new generator before but don’t know where to start. Let’s consider a few things you should consider when looking for a generator for your camping needs.

Fuel Type

The three most popular fuel sources for RV generators are diesel, gas, and propane. Some portable generators even use multiple fuel sources, which can be convenient in an emergency. 

Many RVers choose gas-powered generators because they’re often cheaper, and gasoline is usually easy to come by. One of the disadvantages of gasoline-powered generators is that they often require more upkeep than other generators. It’s also more dangerous to store gasoline than diesel or propane as it has a lower flash point and a shorter shelf life.

Diesel-powered generators are another popular option. They’re great because they require less maintenance and are more efficient. While there are many benefits to choosing a diesel-powered generator, they’re more expensive and require regular use to avoid breaking down.

One last fuel source that’s popular for RV generators is propane. Many people already have a propane tank or two for grills or heaters around their house.

These generators can use these same tanks or connect to larger tanks, depending on how often you use your generator. Propane is much less efficient than gas or diesel fuel for powering a generator.

Noise Level

Having your epic boondocking trip interrupted by a neighbor’s noisy generator is pretty much every boondocking RVer’s nightmare. When purchasing a generator, factor in the level of noise the generator creates while in use.

The volume difference between a generator under a full and empty load is night and day. The noise levels a generator creates are an essential factor for most campers to consider when shopping for a new generator.


Inverter generators have proven a leap forward for portable generator technology. An inverter generator can adapt the engine’s throttle based on demand.

This means generators no longer have to run full throttle the entire time, creating less excess pollution and lower fuel consumption. You’ll save money on fuel and produce less pollution when choosing an inverter generator.


When you’re choosing to spend hundreds, possibly even thousands, of dollars on a generator, you want a quality warranty. If you’re planning to use your portable generator while traveling full-time, you’ll want to be able to use your warranty anywhere in the country.

Purchasing your generator from any popular big-box retailer is a great way to ensure your warranty is valid nationwide.

Where Should You Set Up Your Portable Generator?

A common mistake many RVers make is in the placement of their portable generator. Did you know nearly 900 people died between 2005 and 2017 from carbon monoxide poisoning from a portable generator? Not all of these were RV-related, but placing a generator too close to an RV can be deadly.

When setting up your portable generator, make sure it’s in an open area. Face the generator’s exhaust pipe with the wind, so the exhaust blows away from the RV. Also, keep the generator away from any potential fuel or dry brush to avoid causing a fire. 

How to Use a Portable Generator to Charge Your RV Batteries

If your generator works for RVs, there’s a good chance it’ll come with a 30-amp electrical plug. If your RV is 50-amp, you’ll need to use a special adapter to convert to a 30-amp connection.

Powering your RV with a generator will charge your batteries, much like plugging into a power pedestal at a campground does. It can take several hours to charge your batteries, so don’t expect immediate results.

Or plug a battery charger into your generator and attach the jumper cables to your RV’s batteries. Verify that the charger you’re using is a smart charger and will recognize when the battery is full. If not, you could damage your RV batteries, which could be an expensive mistake.

Portable RV Generators Power Your Off-Grid Adventures

We hope this guide helps you find the best portable generator for your needs. It’s important to know what you’re looking for and what you’ll need the generator to do so that you can spend days off-grid using your generator for power. 

Eat See RV has a good blog article on this topic if you’re not sure how much power you use. While they are referencing solar in the article, the same math would apply to simply figure out how much power you use for a generator.

Lastly, when looking for generators, make sure to search around for the best prices and set aside a small fund for repairs. Service after the sale is very important if issues should arise!

  1. Thanks for the article. We are shopping for a generator and appreciate your take. 👍
    (btw…OHV= over head valve)

  2. Hi Jason

    First, I wish to thank you for this article. So far you are the first RV/Camper blog to mention Harbor Freights’ generators.

    Second, For the money, there is no comparison. Just one thing, The predator 3500 was priced incorrectly, Currently it is selling for $799. I purchased mine for $549 a year ago. I wished I had two in series so I could have the capacity to run both A/C
    s and the microwave at the same time as two in series produces more than 50 amp. I do not work for or related to in any manner for harbor freight, I just hate seeing consumers get taken on all the other overpriced generators.

    1. Thanks Jeff, we have been using the Predator 3500 for two years now and love it so try to preach what we practice.

  3. When comparing low-priced units to well-known brands, it may be helpful to study details only found in the user manuals (readily available online). A top brand unit might require oil changes every 100 hours, while a budget unit might need oil changes much more frequently. Not a big deal if you bring the generator along only for occasional use, but if you plan on running the generator daily, you might want to consider the implications of bringing along replacement oil and storage of used oil for your camping trip. Also, power output is diminished at higher altitude. Does the generator still produce enough power for your planned camping location? Can parts be swapped in the generator to make it run better at high altitude? Will the generator run well enough at all locations included in your trip, without needing parts swapped during the trip?
