Best Dual Fuel Generator (Gas Or Propane)

When power is gone generator is definitely the best alternative you can have.


Generators are available in many types and power variant so that it will meet and supply your own power requirement. Another thing is that, generators are reliable power source and cost effective.

Most of them are portable so that you can bring it along if you’re working on remote places. To give you total convenience and versatility a Dual Fuel Generator is a good choice.

What is a dual fuel generator?

Dual fuel generator means that the generator can be run by either gas of propane. Traditional generators can be powered by gas only while dual fuel generator gives you advantage to choose between gas and propane.

Why choose a dual fuel generator?

As I mention earlier, it provides you with flexibility whichever is more convenient for you to use at the time of power shortage. For instance, at a time of power shortage you don’t have any gasoline at home while propane can be easily found in any household in which you can readily use anytime. This is definitely a life saver in times of emergency.

Gas Vs Propane which is better?

Both of them can be highly reliable to use in a dual fuel generator. However, the question lies in what is the most convenient to use in time of power outage.

If the place you live in has a nearby gasoline station gas could be better for you. Although, during power shortage and the gasoline station don’t have any generator to run the system you can never buy it. Propane is probably the only choice you have which is readily available on your kitchen.

If you’re planning to store more propane at home for longer power shortage you can stockpile as many as you can. Because, it is safe inside its solid steel tank while gasoline won’t last long. Likewise, if you’re planning to take it on a camping trip propane is safer because it never spill unlike gas.

As you can see, propane has a better advantage over gas. However, running your generator on propane gives you lower power capacity compare to running it with gas.

Are Dual Fuel Generators Any Good

Definitely yes, just like any traditional generator they use the same engine. They only differ in the type of fuel source in which they are going to use to run them. In fact, as I discuss above dual fuel generator gives you more advantage over traditional gas powered generator.

Can a dual fuel generator run on natural gas?

The answer is a big NO.

Why is that?

Dual fuel generator can only be run by either gas or propane. If you want to use a natural gas as your source you need a tri-fuel generator. In this case you have already three choices such as gas, propane and natural gas. Others do their own improvisation or conversion so that they can also use a natural gas on their generator.

How long will the generator run on propane tank?

The run time depends on the size of the generator, the size of the propane tank and the load. To give you an example, the DuroStar DS12000EH 12,000 watt dual fuel generator can last up to 8-hours using a 40-pound at half load capacity. Using a 20-pound tank size propane tank will cut its run time into half.

Another example is the Sportsman GEN2000DF 2000 Watt dual fuel generator. As you can notice, it produce only 2,000 watt power capacity and a single 20-pound propane tank in it can lasts up to 12-hours of run time with half load capacity.

Thus increasing the load the generator’s run time will be shorten while decreasing the load will result in a longer run time.

The following dual fuel generators are the best you can have and this will help you find the one right for your needs in any way.
