Best Generators for a Travel Trailer [w/ Reviews]

Getting a portable generator for your travel trailer could be a great investment. It will provide power for your gadgets and appliances making the whole camping experience more comfortable and enjoyable. It will also give you the opportunity to visit campsites and remote areas you otherwise wouldn’t without having access to electrical hookups for your camper.

In this article, I provide brief reviews of the best generators for a camping trailer. You will also find some useful guidelines that may ease you finding the right model for you. But first, let’s check which are the top travel trailer generators based on my research.

What to Consider When Buying a Camper Trailer Generator

There are a few things you should check before buying a travel trailer generator if you don’t want to end up with a model that doesn’t meet your needs. Here are these things:

Wattage Requirements

Make sure the portable generator you are going buy for your travel trailer to have enough power to start up your appliances. Check the starting wattage of your appliances and ensure that the generator can start the device with the highest starting watts without having to unplug other basic appliances first. It is also important to check the running watts of all appliances you plan to use of the same time.

To give you a quick example, a typical 13,500 BTU air conditioner requires 2800-3000 starting watts and 1500-2000 watts to keep running. Therefore, if you plan to run the AC and other basic appliances together, you will need a travel trailer generator with at least 3000 starting watts and at least 2000 running watts.

Type of fuel

Portable generators come with a variety of fuel options – diesel, propane, gasoline and solar powered. It is up to you to decide which one you will choose for your travel trailer. Solar generators are the most environmentally-friendly as they do not produce lots of noise or pollutants. However, expect to spend handsomely on them. Diesel and gasoline generators are user-friendly and relatively affordable, but not very friendly to the environment.

Weight and Size

Look out for a portable generator that can be easily transported in your travel trailer. Bigger is not always better, so do not buy a giant generator because you want more power.


An overly noisy trailer generator can ruin the vibe when camping. So, as you compare different models in terms of power output, consider the noise level and any noise-reducing features that the generators are fitted with.

If neither of the above 2 generators packs enough power for your travel trailer needs, you definitely need to check out the Westinghouse iGen4500.

This is a high-performance portable inverter generator fitted with a 224cc OHV 6HP motor that maximizes 4500 watts of starting power and 3700 rated watts.

Frequently Asked Questions

Do travel trailers have generators?

Most standard travel trailers don’t ship with a built-in generator. However, some motor coaches and 5th wheel trailers do come with one.

Can you add a built-in generator to a trailer?

Yes, you can. Some travel trailers have a built-in spacing for installing a generator, while others don’t. If yours came without, it’s possible to add a generator if you have the skills but considering the effort and cost it requires you would be better to buy a portable generator.

Do I need a generator for a travel trailer?

Well, it might not be necessary if you hang around campsites with electricity hookups. However, if you’ll be venturing further away from the grid, a portable generator becomes necessary.

What size of a portable generator do I need for a travel trailer?

The wattage requirements of the electrical items you plan to use will determine the size of generator you need for your travel trailer. Usually, a 3000-watt generator should be sufficient to power a 13500 btu air conditioner and a few other appliances, such as a fridge, coffee maker, and laptop.

How do you hook up a portable generator to a travel trailer?

  1. Start by driving the ground rod to the ground where you want to install your generator.
  2. Connect the copper wire on the grounding rod to your generator.
  3. Ensure that the generator’s exhaust faces away from the camping trailer.
  4. Plugin the travel trailer connector cable to the portable generator.
  5. Turn on the generator
