Best Dual Fuel Generators (Our Top 6 2022 Picks!)

Purchase your generator for the best price at Amazon.com!

Generators that can produce electricity from two different sources of fuel are known as dual fuel engines. Dual fuel generators typically run on either gasoline or propane as their primary source of power. Gas is readily available nearly everywhere, making it a simple commodity to acquire. However, there are some drawbacks, such as a higher level of noise and a greater amount of exhaust fumes.

The cleaner and quieter propane, on the other hand, comes in handy in an emergency and can be stored in a convenient location. The best dual-fuel generators on the market can be found in this article, so let's get started!

The Best Dual Fuel Generators on the Market

The best dual fuel generators that I have reviewed are now well within your grasp after reading through all of my recommendations. You may have already considered a few possibilities. However, before making a decision on a dual fuel generator, you should research its features and weigh their relative importance in light of your intended use.

There is a good chance that some features of a particular product will not be useful to you. We've put together this detailed buying guide to help you avoid any mishaps. All the properties are described here, so you can choose which ones are most important for your dual fuel generator. To make an informed purchase, be sure to thoroughly review this buyer's guide!

Capacity for fuel

Dual fuel generators have separate fuel tanks because they run on both gasoline and propane. The capacity of each fuel tank varies, so it's impossible to compare them all. Gallons are used to measure this capacity. A 10-gallon tank, for example, can hold no more than 10 gallons of fuel at a time.

Having a tank with a large capacity will benefit you in a number of ways. No need to worry about refueling the generator as long as your fuel tank is large enough, you'll have continuous power output. Be aware that large fuel tanks mean heavier generators.

What's the power like?

A generator's output power is an important consideration when purchasing one for use as a backup power source. Each dual fuel generator has two different output ratings: rated and peak. However, the values for gasoline and propane are different. As a result, each generator has four distinct output values.

It's easy to get lost in all of this, but don't sweat it. If you only consider the generator's maximum power output for both fuel types when making a purchase, you'll get a higher running wattage automatically. However, it is possible to set the peak value of gasoline to be higher than that of propane and thus increase the amount of running watts as well.

How big is it?

The generator's portability is an important consideration if you plan on using it for a variety of purposes. Consider the size and weight of the generator and make sure you will be able to move it yourself. 

In general, heavy-duty generators are larger and heavier than their low-powered counterparts. As a result, transporting a large dual fuel generator, especially one with a full fuel tank, can be difficult. Compact generators, on the other hand, have lower power and fuel capacities because of their smaller size.

How noisy is it?

Dual fuel generators are basically portable engines. Generators make a lot of noise when they're running due to the fact that they're constantly combusting. A fuel generator that is completely silent is impossible to find. It's possible, however, to go with a quieter dual fuel generator.

It's possible that the generator's excessive noise will have a negative impact on your lifestyle if it causes too much disruption. This means that a generator with a lower noise level should always be an option. Remember that if you plan to use propane as your primary fuel, you won't have to worry about noise levels as much because propane performs almost silently.

How efficient is it?

In order to generate electricity, the gasoline or propane contained within each dual fuel generator is burned in the engine. Fuel consumption will vary based on the efficiency of the engine, despite the fact that many power output ratings appear to be the same. It is a measure of how efficiently the fuel can be used to generate power.

You'll run out of gas quickly if your engine is inefficient. You'll also have to deal with a lot of harmful exhaust gasses as a result of improper fuel combustion. As a result, even if you opt for a low-powered engine, be sure to check that it consumes little fuel.


In the event of an unplanned power outage, a dual fuel generator can come in handy. In the event that you are unable to obtain primary fuel, a dual fuel generator provides you with the option of using a secondary fuel instead.

There are many different dual fuel generators on the market to buy, so you need to think about when you would likely use it, why you would use it, and how often you would use it. Then try to match your purchase to those needs.
