5 Best Tri Fuel Generators for 2023 - Buyer's Guide

If you're trying to choose the best tri fuel generator for your needs then you're in the right place. We created this guide to look at 5 of the most popular hybrid generators available in this category from several leading brands.

We'll use our own experience along with customer feedback and reviews to let you know what we really think. All 5 of these options are great generators, so feel free to choose one based on how much power you need and your budget.

We will however let you know our favorite model at the end of this guide. So let's jump straight into looking at these impressive generators.

Introducing Our 5 Best Tri Fuel Generator Options

Below are the 5 portable generator models we'll be looking at today.

They're all CARB compliant and EPA certified so they can be used in all 50 US states. They're great portable power options which can be used as entire home backup solutions during power outages and natural disasters, as well as more frequency daily use cases such as work on construction sites, farms, or for taking on outdoor adventures.

All 5 models can run on one of three different fuel sources at any one time - either gasoline, liquid propane gas (LPG), or natural gas.

Whichever model or manufacturer you choose, gasoline will always deliver the most power, followed by LPG, with natural gas being the least powerful fuel source but a great choice for when you need easy continuous power that's uninterrupted for longer periods of time.

You can click on any one of the generator names below to jump straight to the relevant section on this page, or just keep reading for the full guide.

We've listed some key specifications for each generator for a quick comparison, such as their power outputs with each of the three fuels, engine size, and gas tank size. Keep in mind that when using a propane tank it's up to you which size propane tank you choose. Natural gas of course comes from your home's gas supply, or the natural gas supply wherever you happen to be using the generator.

In each section we provide links to click through and read the full breakdown, description, and list of specifications for each tri fuel model.

Tri Fuel Generator Technology - A Very Quick Explainer

Let's take a quick few seconds to explain what exactly tri fuel generators are and how they different from other generator types.

A generator using tri fuel technology is very similar to a regular portable gas generator or a dual fuel generator. The only difference is that tri fuel models are able to operate using one of three different fuel types - rather than only working with one or two.

Tri fuel generators can use either gasoline, propane, or natural gas. They are designed in a way that allows you to select your fuel source by simply using a built in switch.

The models mentioned in this guide are also electric start generators which means they don't need to be started using a cord, as they have a built in electric starter switch.

If you need more information around the different fuel options read our post here: What is a Tri Fuel Generator and How Do They Work?

Now let's look at the first candidate!

Choosing Between Tri Fuel and Dual Fuel Generators - Do You Need Natural Gas As a Fuel Source?

One last thing to consider is that if you want the benefits of hybrid generators and the ability to choose your fuel type you can absolutely consider a dual fuel generator. These are great alternatives if you'd like to save a little money and have a lot more options to choose from.

You'll find that dual fuel generators are much more common with many of the manufacturers we've mentioned today producing at least 5 different models in that category - often 10 or more.

Of course the one caveat is that a dual fuel generator will not able to use natural gas to power it. So you won't be able to connect it to your home's natural gas supply.

Depending on your likely use cases this may or may not be a big deal. Try to think about your access to both gasoline and propane, their storage considerations, and the likelihood of you needed to hook up your generator to a natural gas supply for long periods of time.

You can see our dual fuel generator collection here.

A Note On Tri Fuel Conversion Kits For Generators

When researching tri fuel portable generators you'll likely see conversion kits mentioned quite often. A conversion kit is essentially a way to modify your generator (gas or dual fuel) so that it can accommodate additional fuel sources. A conversion kit will give you the option of adding either propane or natural gas as a fuel source - or both.

We're not going to cover this process in detail here in this guide as it is considered to be something for more advanced users who are also experienced in generator maintenance and have a good understanding of the underlying workings of these machines.

Additionally, in most cases you'll find that adding a tri fuel kit or using any kind of conversion kits will void the original generator warranty from the manufacturer.

Frequently Asked Questions

Here are a few other tri fuel generator questions you might still need answers to.

What is the most powerful tri fuel portable generator?

The DuroMax XP13000HXT is the most powerful tri fuel portable generator available. DuroMax claim it is the biggest commercially available out of the box model which anyone can buy.

It has a 13,000 peak wattage and a 10,500 running wattage using gasoline. Propane is 12,000/9500. Natural gas is 10,000/8500.

What is the quietest tri fuel generator?

Generators in this category are not known for their low noise levels. The models we've looked at in this guide are all extremely similar in terms of noise. Each of them list the decibel level as 74db. This will be roughly equivalent to the sounds of the average vacuum cleaner when you're standing around 20 feet away.

These generators are fairly heavy duty compared to many models on the market and need enough power to support a whole home. Extra power of course means extra noise.
