Propane produces power that is much quieter and cleaner than that produced by gasoline.

Now that you’re here, you have probably decided to get a dual fuel generator. At this point, the most important question is: Which one should you get? Here we have compiled a list of the top 11 dual fuel generators along with their specs, features, pros, and cons to make the choice easier for you. Let’s dive right in!

11 best dual fuel generator

How to select a dual fuel Generator?

If you’re not a very technical person, this will not be a very easy task. Do not go unprepared to the store because otherwise, the salesman will just sell the most expansive dual fuel generator to you assuring you that it is the best when it is really not. Here are a few things that you should check before purchasing a dual fuel generator.

1. Cost:

This is the most important consideration. Set a budget for how much you can afford to pay. Then look for the best one which is within your budget. This will help you shortlist a few and then eventually buy the best one.

2. Power needs:

Consider what your power needs are. How many appliances do you need to power? How long do the power outages usually last? Power is the factor that decides the cost of the generator so you should decide on that in order to invest efficiently.

3. Noise levels:

If you intend on keeping the generator indoors you need to ensure that the noise levels are around 60 dB which is acceptable and not a nuisance. However any greater than that, it will be like living in a workshop with machines running all the time.

4. Ecological concerns:

If you live in an area with strict air quality laws, you need to check if the generator is EPA or CARB compliant or not. This will ensure low emissions. This way you can keep it inside too.

5. Power outlets and other technical features:

Make sure to check the user-friendly features of the generator for example multiple power outlets, USB ports, and fuel level indicators. This will help you choose the one which fits your needs and is easy to use.

Best Dual Fuel Generator Buying Guide:

Having provided you with suggestions for buying a dual fuel generator, let us now provide you with all the basic information that you need before actually doing the deed. This includes understanding how a dual fuel generator actually works, how is it better than a typical generator, and what qualities you should look for in the perfect dual fuel generator for you. Let’s begin!

The basic working of a dual fuel generator:

A dual fuel generator basically works on the basics of mixing two fuels up to optimum conditions to get the best power output. For example, a dual fuel generator that runs on gas and propane will begin working by using gasoline as fuel and then gradually add propane to its operation until optimum conditions are reached. In addition, it can also work on just one of the two fuels if the other one is not available. This increases ease of use.

Advantages of a dual fuel generator over a conventional generator:

What you need to understand is that a bi-fuel and a dual fuel generator are two completely different generators. Bi-fuel generators are capable of working on two different fuels but it cannot mix them together however a dual fuel generator can either work on two different fuels or a mixture of both of them. Now that that is cleared, let me explain why you should invest in a dual fuel inverter rather than a conventional generator.

1. The option of using two fuels:

The most obvious advantage. You can use either of the two fuels based on availability and cost. You can also use a combination. It is entirely up to you.

Why is that an advantage? Imagine a sudden power outage due to letting’s say a storm? Now you can’t go out to get fuel for your generator and you can just use the fuel that is available at home and not go through the hassle of getting the other one.

2. Efficiency:

They have the ability to provide the same power output for a more efficient amount of fuel as most efficient technology such as fuel monitors. In addition, having the option of using any of the two fuels is also a very efficient choice

3. User friendly:

They can easily be moved in case they need repairs and have features such as an electric start that make them very easy to use. Their installation and maintenance also cost way less than conventional generators.

4. Long-lasting:

Dual fuel generators are usually manufactured based on the fact that they may be used in remote areas or areas where power outages are common due to storms or blizzards. For this reason, they have a strong durable exterior which is not always the case with conventional generators.

5. Eco-friendly:

When running on propane, dual fuel generators are more eco-friendly because propane produces fewer emissions and cleaner power.


Frequently Asked Questions

What is the best dual fuel inverter generator?

Champion 3400-Watt DF inverter generator is the best Dual fuel Inverter generator.

Are dual fuel inverter generators any good?

Dual fuel inverter generators allow you to use two different fuels and also have lower noise levels.

Is it safe to use sensitive electronics with dual fuel generators?

This depends on the percentage of THD of the generator. The lower the THD percentage, the safer it is.

Why is it important to have circuit-backed outlets?

This ensures that you don’t have to manually restart the generator each time there is a power surge.

Is it cheaper to use propane or gas as fuel?

Gasoline generators are usually cheaper to install and have a greater run time.

How much power is enough to run all household appliances?

Around 5000W to 7500W is enough to power all appliances simultaneously.

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

Propane because it has longer run times.


We have provided you with the list of the top 11 dual fuel generators on the market. Now you need to decide which one of them suits your needs. The Westinghouse WGen7500DF would clearly be our first suggestion based on its reliability, power output and efficiency. However, the 3800W Champion and the Duromax XP4850EH are also suitable alternatives for their light weight and eco-friendly features. Now it is up to you to decide which of these fits your needs and likes. Good luck!
