How to choose the Dual-fuel generator?
The following are the criteria we judged our options with, and they are good criteria for you to judge by as well.
There are hundreds of generators available on the market with fancy features. But there is a limited budget for you to choose any generator. Your budget depends on the generator’s power output and the technology used in it. For example, as I said earlier, the inverter generators are expensive, so unless you need them for specific usage, you should choose a non-inverter generator. We have added some of the most affordable dual fuel generators in this guide that will accommodate the need of every user.
Of course, no one wants a generator that is too loud. If you need a super quiet generator for outdoor activities such as camping, then you should opt-in for inverter generator (which we have included in this guide), but they are expensive. For regular use, you can use conventional generator because you need to keep them at least 20 feet away from your house for your safety, and from that distance, their noise output negligible.
The first thing we see in the generator is its power output. To run many appliances simultaneously, you will need a generator with a high power output. But on the other hand, as power output increases, the size of the generator also increases, so this is something you should keep in mind.
If you move around your generator too much, then it is better to have wheels on your generator. Almost all the generators these days come with wheels, but still do not forget to confirm if your selected generator has wheels or not because they are very heavy.
The size of your generator depends on your power requirement. You need to be very practical if you have less space in your house to fit a generator. And since it is a very delicate machine, you need to take care of it to ensure the maximum life expectancy from it.
If you want to connect the generator directly to your home’s mains supply, then it is better to use a transfer switch, and some of the mid-range priced generators do not come with transfer switch, so you will have to purchase it separately. Other than that, you should also look for features like GFCI outlet, surge protector, and voltage guard.
7 Best Dual Fuel Generator Reviews
Here’s a list of the best Dual Fuel Generator we found on the market:
The Champion 3800-Watt Dual Fuel Generator is our top pick, and its features will blow your mind.

Powered by 224cc engine, this generator can be started with one push of a button, and in order to use this feature, the generator comes with an in-built battery. Also, you need to recharge this battery regularly; otherwise, you will have to use the pull-start method.

There are only a handful of dual-fuel inverter generators available on the market and Westinghouse iGen4500DF is one of them. So if you want to enjoy the convenience of dual fuel system with inverter technology, then Westinghouse iGen4500DF is what you need.
This generator can deliver 3700 Rated Watts and 4500 Peak Watts and that too at less than 3% THD (third harmonic distortion). This clean power is very useful when you want to run sensitive electronic devices such as TV, laptop and smartphone.
That’s not all, you will love its wireless remote starting feature, and also, this generator offers electric start, as well as recoil start, if the battery gets discharged.

Affordable Dual Fuel Inverter Generator
As you know, none of the inverter generators come with only propane fuel option, so if you want to use the inverter generator with propane, then you will have to choose the duel fuel option.
But the dual fuel inverter generators are very expensive, however, there are some affordable alternatives available too, and Champion 100402 is one of them.
The Champion 100402 can deliver 1600 running watts and 2000 starting watts, and it can run up to 11 hours on 25% load when 1.1 gallons of the fuel tank is full. You can increase this runtime even more by using the large propane tank.
The 1600 running watts may not be sufficient for users who like to run multiple high power-consuming appliances, so choose wisely. All the inverter generators are designed to produce low but clean power output and this is due to the fact that their internal power converting circuit cannot handle high power.
We advise you to keep the generator at least 20 feet away from the house to protect you from any dangerous CO2 build up. This generator operates at 53dBa from 23 feet distance, which is the same noise level as the average dishwasher’s noise.
This particular generator is EPA certified and CARB compliant, so it is safe to use in California and it produces less harmful gases. You will get three years of warranty on this product, and let’s not forget Champion’s lifetime support and a nationwide network of service
- Lightweight, compact and portable
- Quiet operation with fuel efficiency mode
- Clean power output (less than 3% THD)
- Low power output
- No electric start
Pulsar is a very reputed brand in the world of generators, and they build all sorts of machinery from generators to engines and power tools.
This dual fuel generator can produce 4250 rated watts and 5250 peak watts on gasoline, and on propane, it can produce 3850 rated watts and 4750 peak watts.
And if you feel like this amount of power is not enough for you, then you will be happy to know that there are other variants available of this same model with different power output so don’t forget to check them out.
It has a built-in 4 gallons of fuel tank that will give you about 12 hours of continuous runtime at 50% load. What I like most about this generator is its Switch & Go technology, which allows you to switch between LPG and gasoline even if the generator is still in operation.
You will get a total of 4 output ports, including two 120V AC outlets, one 30-amp RV port, and one 120/240V twist-lock outlets. Apart from that, its fold-down handle and ever-flat tires make the transportation of this generator very effortless and easy.
Moreover, it has other noteworthy features too, such as 3 in 1 digital meter, low oil indicator and low oil shutdown. The only thing I did not like about this generator is its short warranty.
Other manufacturers are offering three years of warranty on this price range whereas the Pulsar is offering only one year warranty.

- Switch & Go technology with RV port
- Available in different variants

Frequently Asked Questions (FAQs)
What is a Dual Fuel Generator?
A dual fuel generator is a generator that can be operated on both gasoline and propane. There are no generators available on the market, which only uses propane as fuel; hence, the dual fuel generator came into existence for the user’s convenience. Similarly, there are tri-fuel generators available too, but they are expensive.
Is it possible to convert a standard generator to dual fuel or LPG?
The answer is yes, but if you are doing it out of curiosity, then you should do it, but if you are doing this to save money, then let me tell you it’s not worth it. You will experience many technical difficulties, and even after that, there is no guarantee that you will get clean and stable power output.
What is the main advantage of a dual fuel generator?
Well, it has many advantages that the list is endless. The first big advantage of using a dual fuel generator is that the propane is cheaper and 33% more efficient than gasoline, so this way, you will be able to save a great deal of money on fuel costs.
As you know, the gasoline tank has limited fuel storage capacity, and if your generator has a small gas tank, then you will have to refuel it frequently. To solve this problem, you can use a large propane tank, and thus, there is no need for frequent refueling.
Choosing the right dual fuel generator isn’t an easy task, but we have made it very easier for you by publishing this guide. With a dual fuel generator, you can enjoy the convenience of using both fuels as you see fit.
Most of the people use propane in their generator because it is cheaper, eliminates the need for frequent refueling, and above all, it emits less harmful gases. We have added generators with different power outputs so you can choose the generator according to your needs.
