Please note that they are just for reference. If you want to know the exact price, don't hesitate to check Amazon.


If you are a first-time client and are unclear about the requirements, we will provide you with suggestions to assist you in choosing the best dual gas generator.

1. Fuel efficiency

Dual-fuel generators may run longer on gasoline and propane than the majority of single-fuel power sources. Naturally, that is based on the amount of fuel you have in your tanks. As with single-fuel generators that only use gas, most dual-fuel generator gas tanks hold between 2 and 10 gallons of fuel. Similar to how you would store propane for a propane barbecue, propane is often kept in separate pressurized gas canisters that are connected by a hose. Therefore, rather than the generator itself, the size of your canister determines the propane capacity.

2. Starting type

A recoil cord or an electric starter are the two starting methods used by dual-fuel generators. You rotate the handle quickly and forcefully with a rope to provide the spin required to start the generator. Although it needs more physical work, it is usually more dependable. No effort is needed with an electric starter, but it only functions when its internal battery is charged.

3. Operating clamor

If you keep one of these noisy machines inside your house or close by, it may become a nuisance. As they produce more electricity, generators often get noisier. You'll want to minimize noise if you're planning to operate your generator while camping in a peaceful area or keep it near your home.


1. Does purchasing a dual fuel generator make sense?

You can have electricity regardless of how awful things become outside thanks to a dual fuel generator. Natural catastrophes like hurricanes and earthquakes can interrupt the supply of fuel. If you are solely dependent on one fuel source, your options may be restricted to what you have on hand.

2. Is there a dual fuel generator from Generac?

A Generac BI-FUELTM generator serves as the answer. These innovative generators offer dual fuel dependability by starting on diesel fuel, adding natural gas when load is applied, and then running mostly on natural gas.

3. Which fuel costs less to power a generator: gasoline or propane?

However, propane only has a 26 MJ/L energy density, which is a little less than a third of what diesel and gasoline have. As a result, if you compare expenses, using diesel or gasoline instead of propane for your generator will result in lower fuel expenditures in an emergency.
