Buying Guide: What to Look for When Buying a Tri-Fuel Generator

Searching for a tri-fuel generator can be a headache because there are too many on the market to choose from. So, you must shortlist them before selecting the best one.

There are certain things you should look into before buying a tri-fuel generator.

I. Where are you going to use the generator?

Not only can you use tri-fuel generators for homes, they can also be used on trips and camping trips. If you are using it for just your home, then we recommend buying a tri-fuel generator. Otherwise, a dual-fuel generator is the best idea for you.

II. Power Outlets

The number of devices that can be powered depends on the number of outlets the tri-fuel generator has. So, it is best to consider the one with at least three outlets.

Most tri-fuel generators come with four 120V outlets. But if there are more, it is even better. You can also look for a twist-lock style power outlet (120V/240V) for refrigerators or air conditioners.

III. Fuel Tank Capacity

Fuel tank capacity is another factor to consider before buying a tri-fuel generator. There are separate fuel tanks for gasoline and propane, while natural gas pipes can be connected directly. Sometimes, only a gasoline tank is provided, and you have to buy and fit the propane tank separately. So, look out for that.

A 6-gallon gasoline fuel tank can give more than 10 hours of running time. It is enough for a household, but it might not be enough if the tri-fuel generator is being used at a work site.

IV. Usage Frequency or Durability of the Generator

Many generators carry a hefty price tag because of their sturdy and reliable design. But sometimes, you don’t need these things. 

If you are going to use the tri-fuel generator daily for a couple of hours, you should pay this price. But if the purpose of buying a tri-fuel generator is emergency power, then there is no need to consider this factor.

Frequently Asked Questions

What Fuel is Cheaper to Use for a Generator: Gas or Propane?

Propane is more efficient than gas but has a slightly higher per-gallon price. Propane burns less and produces more energy than gas, so it is cheaper to use overall.

Which is the Most Efficient Fuel for Generators?

The most efficient fuel is diesel which comes as a fuel option in some tri-fuel generators. But they are rare. The second-best efficient choice is gasoline. After gasoline comes propane and then natural gas.

But it can also vary. You need to be informed on this to decide for your brand and type of generator.

Why Is It Necessary to Have a Tri Fuel Generator?

The advantage you get with tri-fuel generators is flexibility and freedom. Gasoline can be costly in some areas thus, making other fuels a more affordable option. Gasoline can also be hazardous to store in large amounts at home.


After rigorously researching tons of products, we have found Champion Power Equipment 100416 TRI Fuel Natural Gas Generator as the best tri-fuel generator you can buy.
