    What are Dual Fuel Generators?

    As the term “Dual Fuel” suggests, Dual Fuel Generators are the type that run on two different fuels for operation.

    For instance, the generator can run on gasoline or propane separately with a quick transfer switch knob. Hence the generator comes with a single-engine or different engines to accommodate the dual fuel.

    However, whether on a single-engine or different engines, the appearance and power supply of the generator is a determining factor.

    Though the dual-fuel generators can be incredibly portable and lightweight, they can be massive in size. Hence, the application of the generator can range from home to camping, enterprise building, and more.

    What Benefits do they Provide?

    The dual fuel generator provides a wide range of benefits and important features that calls for its massive adoption. Some of them include the following.


    In a case where gasoline isn’t always accessible, you can choose to use another type of fuel like propane or natural gas to power up the generator.


    The dual-fuel generators emit less harmful pollutants compared to conventional generators. Besides, the cost of operation is less.

    Increased operation runtime

    The dual fuel generator operates longer than single fuel generators on the same fuel level using either natural gas or propane.

    Excellent power output

    The dual fuel generator offers an average starting watt of 1500 that is adequate for most home and basic devices.

    Are Dual Fuel Generators Any Good?

    Of course, dual fuel generators are incredibly great. Compared to the other generators that run solely on gas, the duel generators provide better power output and increased operational time.

    Furthermore, when it comes to the cost of operation, the duel fuel generators are less pricey due to propane. Additionally, the duel fuel generators easily ignite in cold weather.

    Moreover, you can rely on a dual fuel generator in the event of a gasoline supply outage. The dual-fuel generators use gasoline and propane as fuel.
