First in my editor’s choice section is the versatile Champion 3400-watt that is loaded with power. With a full tank of 1.6 gallons, the generator delivers 3400 starting watts to ably operate a 15,000 BTU air conditioner and other appliances with ease.

Though I don’t mind much about fuel type, I must admit that the dual fuel function of this unit is pretty convenient.

You can use either gasoline or propane, whichever available around your campground. Take note that the runtime will be different between them. I prefer to use propane because it isn’t out of juice when I need the unit run all night long.

Also love the fact that it’s super-easy to start with the push of a button and really quieter than other RV generators in this field.

Running at 2200 starting watts, of course, Honda EU2200i can’t be as powerful as the previous counterpart to run a 15,000 BTU AC and other large appliances at once. Instead, it’s a good choice to power up a single air conditioner or other small electronics.

If you intend to run everything in your recreational vehicle at the same time, lucky enough that this generator is built with parallel capabilities.

I nearly rank it down because of the too small fuel tank, however, thanks to the Eco-Throttle toggle that allows switching over to fuel efficiency mode, that minus becomes minor.

At ¼ load, it can run continuously 8.1 hours while the noise level is remarkably silent – 48 to 57 dBA. From 23 feet away, I don’t hear it running outside of my RV. Compared to its competitor – Westinghouse Igen2200, I find that this model does have the upper hand.

The final feature is the clean power. If you have some sensitive electronics recharged, count on its reliable power.

How To Choose The Best Inverter Generators For RV?

Power output

  • The power output of your RV generator will be influenced by the electronics and appliances that you’re going to run at the same time. To know exactly how much power it needs to produce, look around your RV for all things that utilize 120 volts and count them up.
  • Take note of two indicators: Running watts and Starting watts.
    • Watts = Volts x Amps
  • House appliances like air conditioners have higher starting watts than another indicator, keep that in mind. The generator that you need should have enough power for the total amount of starting watts needed.
  • In general, 1000-watt generators are a good backup for small electronics like smartphones, laptops, and lights.
  • A 3000-watt model is ideal to fully power up your motorhome – those heavy-duty appliances like 15,000 BTU AC, electric grill, or fridge. A higher power-output generator should be considered for larger RVs.

Fuel Tank Capacity

This feature determines how long your generator can run. The bigger the fuel tank, the longer the generator’s runtime. But not always the bigger the better. You should consider how much power amount for your RV appliances and how long they are needed operating.

For instance, if you intend to run a fridge or AC at night, a bigger fuel tank is obviously better. If your power need is less and not frequent, smaller tanks should come into place. Why?

The biggest disadvantages of getting a generator with a big fuel tank are:

  • Bulkier silhouette

  • Higher price

  • Heavier -> Less transportable for camping or tailgating

It’d better that after figuring out the needed runtime, find a model that runs a bit longer than that. I mean, if you plan to run a generator for 8 hours, choose the model that offers runtime of 9-10 hours.

Noise level

  • A good thing when it comes to choosing an inverter generator is its lower noise level compared to the conventional units. In general, it’s under 60 dBA which is equal to a normal 2-people conversation or window ACs.

  • Try to find out your endurance, don’t look for the quietest if your power demand is high. It’s because the more power output of a generator, the louder it will be.

  • Extension power cords are another idea if you want to get a compromise between silence and greater power capacity. They help you place the unit far from your RV and neighbors, keeping everyone’s night sleep always good and peaceful.

Which Brands Make The best inverter generators for RV?


  • Champion is a worldwide market leader in the generator industry and their biggest strength lies in the innovation, resulting in legendary performance that hardly other brands can beat off.


  • The very first Japanese company in this list but I bet nobody doesn’t know about it. In generator aspects, Honda highlights the perfect compromise of a powerful engine and quiet performance. Plus, is a compact and lightweight design that no campers can’t resist.


  • Established in 1951, WEN is another long-standing brand in this spectrum. Their generators have been well-loved for years for sturdiness, built-in modern technology and importantly, affordable price. That’s why from rare campers to full-time RV-ers, they all love choosing this brand.


  • Westinghouse is a good choice for those who want an economical choice in the long term since their generators are designed with fuel efficiency and safety in mind. If you’re a careful person with a tight budget, go for this.


  • Started with Yamaha Motor group with more than 50 years of experience, no strange that their generator lines are made with perfectionism. While super fuel efficiency and full of innovation, their incredible portability makes their reputation these days.


Do you need an inverter generator for RV?

Despite the only weakness about costly price, I highly recommend inverter generators for RV-ers if your budget is allowed. They come with lots of improved features and superior performance:

  • Lighter, smaller but the same power output

  • Give clean power to handle sensitive electronics

  • Built with the parallel capability to double up the energy output when you need more power

  • Quieter when operating

Are inverter generators better?

Yes, it’s surely better than a conventional generator in terms of performance. If your budget is on the table, go for it.

Do inverter generators run on gas?

Not only run on gasoline, but some modern inverter generators are also designed to ably run on propane or even come with the dual-fuel feature that allows the unit to run both fuel types.

Why are inverter generators so quiet?

Due to the smaller design of inverter generators, which results in a smaller engine, it delivers quieter performance. Plus, this modern technology can adjust the energy output to afford different loads.

At lower load, it runs more quietly, not as loud-all-the-time as the conventional.

Can an inverter generator run a refrigerator?

If the starting wattages of your inverter generator is bigger than the acquired load of the fridge, it’s able to run this house appliance. Check this indicator in the generator’s description and make a small comparison.


There you have it – my ultimate buying guide to choose the best inverter generators for RV. Here is summary:

  • Consider how much power your generator needs to provide

  • Your budget and other extra features you might want to have
