Quick Summary: The Champion 3800-Watt Generator is our top pick for the Best Dual Fuel Generator because of its affordable price range, decent power, and an excellent warranty. This generator can run all the necessary appliances in your home such as TV, refrigerator, and air conditioner. Additionally, it comes with convenient features like electric start, RV outlet, and automatic low oil shutdown.
Electric generators are the real deal. They are incredibly reliable as they provide your house with back-up power if an emergency such as a power outage or a natural disaster occurs.
Dual fuel generators are even better. They run on both propane and gasoline to generate electricity, which in turn massively increases their efficiency.
Running a dual fuel generator on either of the fuel sources has its pros and cons. Gas is easier to obtain, but If you run a fuel generator on gas, it’ll be incredibly loud and produce more fumes. Propane, on the other hand, is a bit expensive, but it is much cleaner and quieter as far as power generation is concerned.
Before you purchase a dual fuel generator, there are a few essential factors to be kept in mind. Firstly, ensure what the fuel capacity of that generator is. A fuel generator has a specific capacity, which indicates how much fuel a generator can hold.
Secondly, make sure what the output of the generator is. This will aid you in determining how many appliances can work at a time. And thirdly, the noise level of the generator. Choose one which makes the least amount of noise.
We have fashioned for you a list of the best Dual Fuel Generators out there, which will assist you in making the right decision in your quest to find a dual fuel generator.

Best for Fuel Savings
5. Champion 100402 2000-Watt Dual Fuel 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.

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.

How to Choose A Good 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.
Budget
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 and the technology used in it.
For example, as I said earlier, the inverter machines 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.
Noise Level
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 an 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.
Power Output
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 output increases, the size of the generator also increases, so this is something you should keep in mind.
Portability
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.
Size
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.
Safety Features
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 a 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.
Frequently Asked Questions
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.
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.
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.
Final Verdict: Best Duel Fuel Generators
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.
