Top 6 Best Generators for Travel Trailer – 2020 Update

Best Champion Generators (Reviews)

No one can resist the wild feelings from long-day campings. But, traveling with friends or family might become frustrating if your generator gets broken. The lights, the air conditioner, the cookers, the TV, all the comforts in the RV become useless.

Or if your generator does not generate an enough-stable electric flow, you cannot use it to charge your smartphones and TVs or they’ll be seriously harmed. As a result, you’ll have a not-so-much-fun camping trip, or worse, you’ll have to go home in the middle of the camping.

That’s why I’m going to review some good generators for travel trailers in this article. Hope you’ll find it helpful.

Here are my top picks for the Best Generators for Travel Trailer:

  • Westinghouse iGen2500 – Best Overall
  • Generac GP3000i – Quickest Start
  • WEN 56380i – Ultra-quiet
  • Pulsar PG4000iSR – Remote Start
  • Champion 4000-Watt – Powerful & Affordable
  • Westinghouse iGen4200 – Highest Peak Watts & Longest Runtime

First, you’ll need to know that there are three common types of portable generators: Traditional, Inverter, and Hybrid. All three types have one thing in common is that they can generate electricity from fuel (e.g., gasoline, diesel or propane).

Traditional generators (or conventional generators) are the oldest model. They are low-price, powerful but loud and the electric flow highly fluctuates. So they are not popular these days, only used for some construction works.

I’ll skip this type of generators because they are the worst choice for travel trailers. I’ll review Inverter and Hybrid generators.

Inverter Generators

As the name has said, inverter generators have a built-in inverter. It helps stabilize the electric flow, thus, the output power is safe for sensitive electrics, such as smartphones or TVs.

Technically, it uses fuel as input power, then using a mechanical alternator to produce AC power just like a traditional generator. But after that, the inverter generator converts that AC power to DC power, then once again digitally inverting it back to a cleaner and higher-frequency AC power.

On some models, you can use DC sources (e.g., solar panels or car batteries) as the input power. And moreover, they operate quietly and efficiently. Inverter generators are now the most preferred type of generators.

But they are not as powerful as the traditional (at a given price). So, they are perfect for resident purposes, such as camping trips, parties, or power outages.

Hybrid Inverter Open Frame Generators

Between traditional generators and inverter generators are hybrid generators – the newest-invented type of portable generators. They combine traditional generator sets with another controllable electric source for power efficiency, noise reduction, and environment protection.

It means that instead of converting all the initial AC power to DC power, then inverting all the DC power back to AC power as an inverter generator does, a hybrid generator uses a different (small amount) electric source to stabilize the initial AC power.

It does not convert all the power back and forth, so it can produce more power but maintains all the advantages of an inverter generator.

However, of course, the output power of a hybrid generator can only be less than 3% THD, while the output of an inverter generator can even be less than 1.2% THD. But this difference is not significant.

How to choose a good generator for travel trailer?

There are a few factors you need to take into account:

Output power and quality: You’ll want your generator output wattage higher than your RV air conditioner wattage, or the conditioner would not start or operate properly. Take into account both starting watts and running watts.

You’ll also want the electric flow to be clean and stable enough, or you cannot use it to power and charge your smartphones or TVs. Ideally, the output flow should be less than 3% THD.

Noise level: You won’t want the noise from the generator to interrupt your sleep or camping activities. So, I recommend a generator that operates below 70 dB.

Runtime: No one uses an RV for a day trip, right? It’ll last for at least one day and one night. So, the runtime of the generator is very important. Choose a generator with a long runtime and you don’t need to care much about it during the trips.

Who makes the best generators for travel trailer?

Westinghouse Electric Corporation

Westinghouse Electric was founded on January 8, 1886 – nearly 150 years to now. At present, they have factories across American and is one of the best brands in the industry thanks to their intensive experience in making generators.

Westinghouse is known for R&D innovations, which bring them more than 28,000 US government patents in the 20th century.

Generac Power Systems

Generac Power Systems is another truth-worthing generator maker, based in Waukesha, Wisconsin. They have a wide range of generator, using different technologies, and for different purposes. With years of experience in the generator manufacturing industry, Generac products are always of high quality and innovative features.


WEN for me is the best generator maker in terms of quietness. The company was founded in 1951 by Nick Anton, and 50 years later, had sold more than 50 million units by 2001. They have an experienced R&D team that knows how to integrate pioneered technologies into their products.

Besides generators, they also produce many power tools-  chainsaws, jigsaws, engravers, soldering guns, air compressors, and so on. All are high quality and affordable.

Champion Power Equipment

Champion Power Equipment is located in the US and has sold more than 2.5 million power generation tools in North America. Besides portable generators, home standby generators, inverter generators, they also have different product lines, such as winches and log splitters and engines.

The thing that makes them stand out in the industry is their great customer service. They offer a 3-year warranty program for almost all products with lifetime support.


How big of a generator do I need for my travel trailer?

Generally, air conditioners consume the most wattage in your RVs. So you can base on your conditioner watts to choose the generator. Typically, an RV air conditioner requires above 2000 starting watts and 1500 running watts.

You can get a generator as big as you want, but don’t choose an over-capacity one because you don’t want a tool that is too heavy, bulky and consumes a lot of fuel.

How much fuel does an RV generator use?

It depends on many factors, such as your generator technologies, the type of fuel, the appliances you are powered up.

Many things need to be taken in account, but I can give you a reference number – typical 5,000-watt gasoline generator burns about 18 gal gasoline in 24 hours. You can check the specifications of the generator before purchasing it to know the burning rate.

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

Propane has a higher energy density than gas, but it’s nothing compared with the cost. Propane is nearly one-and-a-half more expensive than gas. So gas would be cheaper.

Is it OK to run generator while driving RV?

Yes, it is 100% OK.

What is the average life of a generator?

A decent generator comes with 3 years of warranty. But if you maintain it properly, it will last for decades.


Above are my full review of the best generators for travel trailer. Hope that the information in this article will help you find the suitable RV generator for you.
