Best Dual Fuel Portable Generator

Are you contemplating if a dual fuel generator will be good for you or not? If yes, then go for it if you rarely want to extend the running time of your generator. Technically, the propane will stand in the gap while you seek possible ways to refill the gasoline in your tank.

Some people understand the need for a backup generator, and many like portable gas generators for camping trips, tailgate parties, or a day at the park.

But why try to get the best dual fuel portable generator?

The point of having a generator for many is to have a backup, right? The generator is what you trot out when you have a power outage at home.

If you have a portable version, you can bring your generator for your camping trips so you’re sure you have the power to recharge your mobile devices plus you can provide power for lights and a few nice appliances.

But relying on just a single fuel option isn’t always a good thing, especially with gasoline. With a dual fuel generator, though, you always have the option of using propane if you have some.

Propane is often the better choice—it’s a cleaner sour of fuel, it’s more affordable than gasoline, and when you’re using propane the generator isn’t as noisy.

Sometimes you can even use both, so when you run out of gasoline you can switch to propane. This means you can extend the run time of your generator, which is great for extended camping trips or power outages.

What Does Dual Fuel Mean on a Generator?

All generators are powered by fuel, in one way or the other. The portable ones use gasoline and propane, while the permanently placed ones use natural gas, diesel, and liquid fuels. Some generators use a single fueling means, but some use two with interchangeable switches.

The dual-fuel feature is common among portable generators. Such generators are known to use both gasoline and propane. The tank on them is designated for gasoline, while a pipe has to run from the generator to a propane tank to get the right outcome.

Is It Worth Getting a Dual Fuel Generator?

Yes, it does. A dual fuel generator expands one’s scope of generator usage. Aside from that, it extends the usage time of the generator. Users can now flexibly use their generators even amid fuel scarcities. No more restraints as long as this feature predominantly overwhelms the value of a generator. In short, it is worth having a dual fuel generator.

How Does a Dual Fuel Generator Work?

This works like any other generator. The generator has its power switch. Its switch power can be in the form of an electric start or a recoil. Identify the fuel-switching button on the control panel. Switch on the ignition power once you set the fueling means to your preferred choice. The engine will start immediately, and all electronic signals will be conveyed to the functions.

Are Dual Fuel Generators a Good Idea?

Yes, buying them is a good idea if you intend to use your generator for hours. When the gasoline fuel finishes, the propane fuel takes over. Invariably, if you need a portable generator that you can use to execute projects on sites, then dual fuel generators are what you should go for any time.

How Long Will a Dual Fuel Generator Run on Propane?

It depends on the engine of the generator. The electricity rate the engine will generate may likely dwindle a bit compared to what gasoline would provide. However, if an engine can run a 1.1gal of gasoline for ten hours, expect the same engine to run propane of the exact measurement for 12hrs. Indeed, that is what you get with the use of a dual fuel generator.

Buying Guide – How to Choose the Dual Fuel Portable Generator?


Here are some factors that may help you before buying your best portable emergency generator.

  • Power. The more appliances you need to power and the more power-hungry these appliances are, the more watts you need for your generator. The typical dual fuel generators are quite powerful, with many able to offer up to 5,000 watts. The most powerful ones can go up to 10,000 watts. It’s not easy to find one with less than 3,500 watts.
  • Size and portability. Unfortunately, you pay a penalty in the size and weight you have to deal with when you opt for the more powerful generators. Still, you may find some units that are light enough for 2 men to carry, while they may also come with sturdy wheels so you’re able to move them from one spot to another.
  • Ease of use. This shouldn’t be overly complicated at all. It should be easy enough for an average 10-year old child to understand how to use it. It’s best if your unit has a detailed manual with lots of online videos you can check out, while you also have a screen showing you the generator status and remaining power levels.
  • Noise levels. Gasoline-fueled generators can be extremely noisy, and not every manufacturer is absolutely honest about the noise levels of their products. They can be as loud as a vacuum cleaner, and in some cases they can make conversations impossible to hear. So you really need the least noisy unit you can find, so you don’t annoy other people near you.
  • It’s great if you have carious safety measures in place, such as automatic shutdown in case of low fuel. You need indicator lights for oil levels, and a circuit breaker can be useful too.
  • Local laws. If you’re in California, you need a generator that’s CARB-compliant. Some people also value generators that comply with EPA regulations.

How to Use Dual Fuel Portable Generator?

The best answer to this question is in your owner’s manual. So consult it and keep it handy when you use your dual fuel generator. You can also go online and download the manual in PDF mode if you didn’t get one with your purchase.

If an average child in grade school can’t figure out how to use a particular generator, then it’s just overly complicated. The key steps are simple:

  • Fill it up with your chosen fuel.
  • Start the generator.
  • Plug in your appliances, turn them on, and enjoy.
  • If you’re using gasoline, make sure you have proper ventilation.

What is a dual fuel generator?

Dual fuel is a kind of generator that runs on both diesel and gasoline. That uses an advanced fuel system to switch from one fuel to one another. So the user is able to choose which type of fuel is best suited for that day’s circumstances.

The reason you should get a dual fuel portable generator

Dual fuel generators produce optimum amounts of electricity per gallon regarding fuel. The dual fuel burning process is very efficient. So, it generates the most energy through each type of fuel loaded into the tanks.

Have lower emission levels

Dual fuel generators produce very low ranges of emissions and it can control consumption. Furthermore, they have very low levels of carbon dioxide (co2) production. Hence, they are even greener and therefore better regarding the environment.

More reliable than single fuel generators

Dual fuel generator engines have been designed with reliable components. This helps them to last for a long time. Additionally, they produce maximum electrical power. Due to these types of characteristics, dual fuel generators are more reliable than some other types.

Are cost-effective to run

Dual fuel generators produce maximum ranges of electricity per unit. It has been already proved that dual fuel generators are more cost effective to run. So you don’t require much fuel to always keep them running.

Provide longer running times
