A Look At The Top 5 Dual Fuel Generators

A dual fuel generator allows you to use two different types of fuel to fuel one generator, as you might have guessed! A dual fuel generator usually accepts either gasoline or propane gas as fuel sources. Ever since the generator was initially invented, it has helped people all over the world overcome power losses, be that in their home, their business, or when in remote areas. Generators, like all other products, are constantly advancing and becoming more technical. Today, there are now generators that offer the ability to be fuelled with all 3 main fuels – gasoline, diesel, and propane gas (also known as LPG).

On the vast majority of dual-fuel generators, either fuel type can be used, assuming both are connected. They can be easily switched between at any time. Gasoline is great, but so too is propane. Each has its advantages over the other. Propane, for example, is a clean fuel that leaves no carbon deposits when burned. It’s also not as expensive as regular gasoline and often runs more quietly too.

Whilst a dual fuel generator is great, a tri-fuel generator could be even more suitable if you aren’t sure about which fuel you’re most likely to have readily available at any one time. They provide the assurance that assuming you have some type of fuel, you’ll always have access to power. They are a relatively new phenomenon in the power generation world, and the market for them, therefore, is growing more quickly than ever.

In this guide, we’ll be examining the 5 dual fuel generators that we believe to be the best available. Included will be a wide range of models that cater to different needs, such as camping, RV use, and those that are better for use with heavier machinery and appliances. The main points that we’ll look at when reviewing each generator are how efficient the generator is, how refined it is (whether or not it’s quiet), how powerful it is, how portable it is, and finally the quality of the power which it outputs.
