Best Dual Fuel Generator– Welcome to the backline outdoors guide to the best dual fuel generator reviews of this year.
What is a dual fuel generator? Dual-fuel generators, sometimes known as hybrid portable generators, can run on two types of fuel: gasoline and propane, or natural gas in some cases. They are some of the best propane generators.
Gasoline is the most common generator fuel, but it has several drawbacks, such as being difficult to store and being subject to price swings, something propane does not have. Propane is usually less expensive, which lowers your running costs. It can also be stored forever and lessens the machine’s noise level. Having both alternatives allow for operational cost, run time, and storage freedom.
They’re frequently mixed up with bi-fuel generators, which use two types of fuel but rely on them both. Due to its dual power system, it will provide higher reliability than other backup systems such as diesel generators, solar generators, or single-fuel generators.
These are suitable for whole house (heavy duty models), RV, and camping with less hazardous emissions (e.g., CO) than diesel-only models, and some dual fuel models have low total harmonic distortion (low THD) (clean sine power) so you can run your sensitive electronics as well. When compared to regular generators, dual fuel generators are a more cost-effective and environmentally friendly source of power.
It’s critical to choose a high-quality dual fuel generator, as lower-quality models will cost you more in fuel for less power. In this guide, we’ll look at some of the best dual fuel generators for homes and businesses on the market today.
This article will help you determine who makes the best dual fuel generator by going over some of the key features of quality generators.

What Are the Advantages of A Dual Fuel Generator?
Personal view will determine whether or not to invest in some of the best dual fuel generators.
However, for many homes, the ability to switch between two types of fuel is a great option. If you have propane tanks on hand, for example, you may easily utilize them instead of gas.
When considering whether to invest a dual fuel generator or remain with your current model, consider the following advantages:
Easy to Use
The freedom to switch the type of fuel you wish to use or that is available is the most evident benefit.
The variety of outlets on these units is one of the most important and user-friendly features. Instead of just one or two types, there are a range to choose from.
Many include a push-start or remote-start feature, which eliminates the need to crank the engine. Depending on the model you buy, you may easily switch between fuel sources with a simple press of a button, switch, or lever.
Some generators contain a mix of RV and household outlets, as well as DC outlets that look like cigarette lighters.
Besides, you need remember to replenish the fuel tank often and without spill, with a gasoline only generator.
With a propane generator, you are freed from the continual fueling task. Therefore, the portable dual fuel generator adds to its single fuel equivalents in terms of efficiency. Dual-fuel generators are equally practical with the added advantage of a choice of tank options.
A dual fuel generator is a cost-effective option. It allows you to save money because you will no longer be reliant on gasoline as your primary source of fuel.
In terms of efficiency and efficacy, gasoline and propane are quite different chemicals. When it comes to creating electricity, gasoline outperforms propane. Its efficiency is expressed in BTUs per gallon. So, if you’re primarily concerned with energy efficiency, such as during a long power outage, gasoline is the best option.
Instead of only relying on gasoline, you have the option of using propane. Because propane is less expensive than gasoline, the savings will pile up quickly. It’s also a highly fuel-efficient generator to choose from.
Even with a 50% load, the propane generator will last longer than the gas generator.
When you’re using a dual fuel generator, you can choose between these two options. If you use a single-fuel generator, you won’t have this option.
Flexibility in Emergencies
In the event of an emergency, a dual fuel generator can provide you with the options you need.
You don’t have to stress about running out of gas to run your generator and you can quickly and easily switch between fuels. As a result, if your gas connection is disrupted due to a disaster, you can swap to the fuel source you have.
Dual fuel portable generators are easy to maintain since they can be moved quickly for repairs if they break down.
They’re also less expensive than whole-house generators, which require a lot of upkeep and appropriate installation.
Propane is a clean burning fuel; this helps your generator requiring less maintenance. There will be little to no residue that can go into the generator’s parts and damage them.
Continuous Power Supply
You can be confident of a constant power supply with a fuel-efficient dual fuel generator.
This is critical for any appliances that must remain operational during a power outage. This is also true for hospitals, industries, and other companies that might benefit from a reliable dual fuel generator.
This means that gasoline’s high-efficiency, high-risk character is best saved for emergency emergencies. A supplementary fuel source, on the other hand, is better for longer or more casual periods of use. You only have two choices: buy two separate generators or buy a single dual fuel generator.
Gasoline burns more quickly, but it also offers greater power. The size of the generator’s built-in fuel tank, which generally stores only a few gallons, determines the average runtime on gas.
Propane, on the other hand, burns slowly but produces less power. Tanks for propane range in size from 5 Gallon to 500 Gallon.
Dual-fuel generators give the best of both worlds rather than relying on a single fuel type. If your chosen fuel is available, you can switch to the other. You can run your generator constantly for at least 24 hours if you use two types of fuel. Especially useful in the event of natural disasters or when a fuel source is inaccessible.
Some generators are more portable than others. Some models have folding handlebars and highly maneuverable never-flat tires.
Buying one of these means that you will never have to worry about transporting any size generators from one location to another.
What Are the Potential Downsides of Dual Fuel Generators?
The major issue you’ll encounter is that a large dual-fuel models will be more expensive than a single-fuel model of the same size.
Alternatively, you might compare them to a tri-fuel generator and argue that they lack a third fuel type, putting them at a disadvantage once more. However, they are minor drawbacks. A dual fuel generator is a great tool to have on its own.
You’ll need to budget ahead of time and handle for the best dual fuel generator to meet your needs at a reasonable price.
The second drawback that comes to mind is that carrying extremely heavy propane tanks. They must also be linked to the generator at all times when it is running.
The fact that propane is a little less powerful in energy generation than gasoline is a small drawback. As you can see, while running on propane, most dual fuel generators produce a lower wattage.
Finally, unlike gasoline, which can be found at any gas station, propane bottles can be a little more difficult to come by.
Before You Buy a Dual Fuel Generator !
There are several things to think about before purchasing a dual fuel generator to make sure it will fit your needs.
Dual fuel generators offer power to your home, campsite, or job site using both gasoline and propane. Compared to single-fuel generators, these generators are larger and less portable. It might also be inconvenient to transport two different types of fuel.
If noise levels are an issue, the propane mode is advantageous because it operates silently. If you truly want a generator that runs quietly, a dual fuel inverter generator is a better choice.
Instead of an alternator, which is often seen on open-frame portable generators, the dual fuel inverter generators have an insulated body and provides power via a computer-controlled inverter.
Best Dual Fuel Generator: Buying Guide
Understanding the main benefits of a dual fuel generator is a great place to start.
After that, it’s time to start which generator is the best fit for you. The Best Dual Fuel Generators are available in a range of sizes, and you should select one that is large enough to provide the energy you want without being extravagant.
Now let’s discuss the factors to look out for in your new dual fuel generator before making a purchase.
These generators feature separate fuel tanks to store gasoline.
Because each tank has its unique capacity, not all fuel tanks are the same. This capacity is measured in gallons and can range from 2 gallons to more than 10 gallons. Having a high-capacity tank will benefit you in a variety of ways. You won’t have to worry about refilling the generator frequently if you have a large fuel tank.
The larger the fuel tank on the generator, the longer it will be able to supply gasoline-based power, but it will also increase the size of the generator.
The capacity of your dual fuel generator has no bearing on how much propane you can burn. Because propane gas is kept under pressure in tanks that are connected to the generator through a hose and pressure regulator for direct fuel consumption.
Watts (W) are used to measure the power output of generators, and it is reported in peak and running watts.
Running power output is the average amount of Watts generated throughout usage, whereas peak power output is the maximum Watts the generator can supply at any given time.
Depending on the size of the generator, the generator may produce anywhere from 1,000 to over 12,000 Watts of power. Depending on the manufacturer, this can be further split down into peak and running power output of propane and gasoline. Because gasoline can provide more wattage than propane, these figures are often given separately.
Also, the wattage output varies depending on whether the portable generator is powered by gas or propane.
Propane will typically run at a 10-15% lower power level. A 4000-Watt model, for example, will supply 4,000 Watt on gasoline and 3,600 Watt on propane.
Of course, the budget will play a significant role. A dual fuel generator can cost anything from a few hundred dollars to a few thousand dollars. Prices will be high at higher watts.
When buying a generator for backup power, you must consider the amount of power you can get from generator vs. what you need.
Electric Start vs. Recoil Cord
Generators with electric start are very easy to operate. When you push the button on the keypad or keyfob, or flip the switch, the generator saves additional electricity in an internal battery that is utilized to automatically start the generator.
The recoil cord is an outdated but dependable technology that has long been seen in generators, chainsaws, lawnmowers, and other fuel-powered power tools. This technique of starting the generator needs you to pull the recoil cord quickly and steadily to start the engine.
Every dual fuel generator is powered by an engine that burns gasoline or propane to burn energy.
While various power output ratings may appear to be similar, fuel consumption will vary due to engine efficiency. The engine efficiency essentially indicates how effectively fuel may be utilized to generate energy. If the engine is efficient, you will run out of fuel quickly.
The number and type of outlets in your generator are two things that are sometimes neglected.
Almost all models have a pair of conventional 120V AC outlets, which are sufficient for most home appliances. 240V outlets or automobile 12V DC outlets may be required by RVs. Before making investment, compare different models.
Any power tool or equipment will make some noise, but the aim is to find a dual fuel generator that makes the least amount of noise while yet producing enough power for your needs.
Based on the size of the generator, the fuel utilized, and the power output of the unit, a dual fuel generator will create a dB level ranging from 50 to 90 decibels. Most generators have a noise level of 65 to 75 decibels, which is roughly the same as a hairdryer. Opt for a small, quiet dual fuel generator if this is still too noisy for your needs.
Some dual fuel generators are bulky, with hoses and tanks that make them difficult to transport.
Manufacturers have begun adding wheel kits with their products in acknowledgment of this mobility limitation, allowing you to tilt the generator and wheel to whichever position you had in mind.
Wheel kits are sometimes supplied separately so that you could add them to your current generator or change an older wheel kit that isn’t functioning. A wheel kit, in either case, will make transporting your dual fuel generator a lot easier.
Dual Fuel Generator: FAQs

Dual fuel models are a better and more adaptable option since they allow you to switch from propane to gasoline if you run out. They’re also more advanced in design and run quietly and more consistently than old single fuel generator.
Tri-fuel generators are also available, but they are quite rare and, in my opinion, are a bit overkill, since they do not function well enough to warrant their higher cost.
To summarize, dual fuel is the best option.
Is There a Honda Dual Fuel Inverter Generator?
Honda does not make a dual fuel generator at present time, despite the fact that their generators are highly fuel-efficient.
They do have a number of very quiet inverter generators on hand. However, instead of running on gas and propane, they all now run on only gas.
Honda may produce dual-fuel units in the future, given the growing popularity of dual-fuel generators on the market. You may purchase customized conversion kits to convert your existing gasoline generator to a dual-fuel. Working with a professional to convert the unit is advised to guarantee it is done correctly.
Is There a Generac Dual Fuel Generator?
Yes. Generac produces industrial generators that can run on both diesel and natural gas. These are known as bi-fuel generator. It begins with diesel fuel and gradually adds natural gas until it runs entirely on natural gas.
Because Generac BI-FUEL generators run largely on natural gas, which is less expensive than diesel, long-term fuel expenditures are considerably reduced.
Because every component is made in-house, these units are EPA-compliant right out of the box.
Do Dual Fuel Generators Have Remote Start?
Some generators offer a remote start, which is one of the best features.
The generator may be started remotely from anywhere. Similar to a key fob for your car, a remote may be used to start the generator from inside your RV or house.
This feature is useful for everyday ease or in the event of a natural disaster when you are unable to go outside.
Can Dual Fuel Generators Run on Natural Gas?
The majority of generators available for everyday usage are not equipped to run on natural gas.
Having said that, you may purchase kits that enable you to convert them to natural gas-powered models.
Natural gas is somewhat more challenging to include due to the significant variations in their operating temperatures. There are tri-fuel generators that permit this. Additionally, if you’re prepared to pay a little extra, you can find a diesel and natural gas dual fuel generator, such as the Generac Bi-fuel series.
N.B. We highly suggested that you see the user’s manual to find whether the device is capable of conversion.
What Is the Best Quiet Dual Fuel Generator?
Champion Power Equipment makes one of the quietest dual fuel generators. The Champion Power Equipment 200961 2500-Watt RV ready portable dual fuel inverter generator is out choice.
How Long Will a Dual Fuel Generator Run on Propane Fuel?
A propane tank for a generator may hold between 5 and 500 gallons of fuel (above ground).
A propane powered generator can burn around 2-3 gallons of propane fuel every hour. So, a 20-pound propane tank will last around 2 hours. A 500-gallon tank can provide continuous power to a family for up to a week.
