What Is A Dual Fuel Generator?
A dual fuel generator, as you can understand by its name, is powered by two different fuels. Mostly, these generators use natural gas and diesel as the two fuels. Also, in most cases, you can use these fuels in varied proportions. Otherwise, some generators bring the facility to use only one fuel at a time. You should not confuse this generator with bi-fuel generators. The reason is that bi-fuel generators use a couple of different types of fuel interchangeably.
When you take the case of the best dual fuel generator, you can easily shift between the fuels. For this switching, there will be an easy-to-turn fuel selector knob. The good thing about a generator that permits the use of two different fuels is that it is capable enough of operating on just a single source of fuel in the absence of the other. However, in most cases, the generators need that there should be one specific fuel to start the engine. For instance, most generators use diesel as the starting fuel. The reason is that diesel ignites at just 500-7000F. With these things known, you will be interested in learning how does this system work. Let us find out here:
How Do Dual Fuel Generators Work?
As mentioned earlier, a dual power generator will have a switch that will help you easily switch between the two types of fuels. In most instances, you can power the generator only using one fuel. This is a good option as you can make the generator continue to power your devices even if one fuel finishes by switching it to the other fuel. So, you can prevent the generator from going off due to low or no fuel. Some generators provide the option to automatically get a power supply once there is a power cut in your home or office.
To know how a fuel generator that uses two different fuels work, you should have a closer look at each stage of the process. Initially, you will have to start the generator. In most instances, it will need a particular type of fuel for igniting the engine and for warming up the generator. You cannot start the engine without the specific fuel that a generator demands. Once the generator warms up, the other fuel can be slowly added. You can do this until the right combination of the fuels is achieved. Even though these generators can accept two different fuels, they can also function slowly on one fuel alone. This will help when the supply of a particular fuel is disturbed. In turn, you can ensure that your appliances continue to function without going off.
Once the generator starts with fuel, the other fuel combines it to the starting fuel slowly. Most of these generators come with different outlets. So, you plug in some of your devices directly to the generators to power them. You can also connect the generator to your home’s electricity outlet to power your entire home in the case of a power off.
What Are the Benefits of Dual Fuel Generators?
Are you looking for a power generator that carries dependability and convenience? If so, a dual fuel generator can be the right choice for you. The good thing about this generator is that it can provide the convenience of powering your devices as and when you need even when you are off-grid. Above all, these are durable devices will help you can get an uninterrupted power supply. The reason is that even when one fuel is finished, you have the option to shift the generator to use the other fuel.
2. They Are Economical
The good thing about a fuel generator that uses two different fuels is that they have engines that are not only easy to operate but also easy to maintain. Further, they are economical as well because irrespective of the fuel you use, the consumption will be low. If you are looking for maximizing the energy output, you can think about buying this type of generator. You can run them even when the fuel is at a low level. So, they are cost-effective to operate your appliances.
3. Peace of Mind
As a portable generator with dual fuel can function in any terrain, you can get complete peace of mind that you have power handy no matter how bad things get out there. Even, when you face natural disasters like earthquakes or hurricanes that can disrupt gasoline supply, you can rely on this generator as it can operate on the other fuel.
4. No Need to Store Expensive Fuel
One of the biggest advantages of a dual fuel generator is that it will eliminate the requirement to store a needless amount of expensive fuel. The reason is that you have two fuels. When one fuel is completely used, you can easily switch the mode of the generator to use the other fuel. So, you get the time to buy the second fuel when the generator functions on one fuel. If you live in a region, where fuel prices change daily, you have the option to buy the fuel on a day with comparatively competitive pricing. You are relieved of buying a particular fuel in bulk as storage of fuel should be done with the utmost care, as you know.
5. Suitable for Different Terrains
The good thing about the best dual fuel generator is that it will be useful in areas with extremely cold winters and hot summers. The reason is that when you take the case of a generator with gasoline as one of the fuels, this fuel fires better in freezing temperatures as compared to the other fuel propane. Nevertheless, propane is a better source of fuel in areas with warm temperatures. In the case of regions with possibility to natural disasters, this type of generator will turn out to be a wise investment option. The reason is that natural disasters can reduce access to certain types of fuels.
How to Choose A Dual Fuel Generator?
A dual power generator uses propane and gasoline as dual fuels in most cases. When talking about fuel, gas is a fuel that is pretty easy to get. The reason is that it is easily available almost anywhere. Nevertheless, it has some disadvantages like more exhaust fumes and high noise. When you take the case of propane, it is quieter and cleaner when using it for power generation. When you intend to shop for this generator, you will have to consider different factors. In turn, you can end up making the right choice. Here are some factors to consider:
1. Power Output
When you shortlist a particular fuel generator, you should consider the power output of the unit. Higher the power outlet, the more devices you can power for a long time. Many manufacturers provide details about the utmost output a generator can produce. You can get to know the running power output and peak power output of a generator before buying it. You should also consider the peak power output. In dual-powered generators, the power output ranges from 1000 to 12000 watts.
As these generators have two sources of power, manufacturers give details about the utmost power output in propane and gasoline. You will find that the power output on propane will be a little less as compared to gasoline. For instance, if a generator can produce 10000 watts of running power in gasoline, it can produce 9000 watts of running power on propane.
2. Fuel Capacity
A portable generator functioning using two fuels will generally have an isolated gasoline tank. This tank can have a fuel capacity that ranges from as few as two gallons to as high as 10 gallons. Yes, you are right! The higher the tank capacity, the longer the generator can power your devices using gasoline. But, when the size of the tank increases, the overall size of the generator will also increase. When talking about fuel capacity, it has no effect on the level of propane you can use for powering the generator. The reason is that in most models, propane gas is filled under pressure in cans. These cans are attached to the generator using a pressure regulator and hose for straight fuel consumption. So, if you need better capacity, you cannot expect portability. Decide which one is important to you and accordingly make your choice.
3. Control Systems and Management
A dual fuel generator can have the best control system when it offers a wide range of features. For example, if a generator has the ability to start remotely and it has low-fuel auto shut-off these are good features. Also, when the unit has a display unit that provides a wide range of data including fuel availability, you can ensure that you do not run out of fuel.
Nowadays, many generators come with Power Management Systems. With this feature, you can configure the unit with ease. More than the presence of control systems, it is equally important that they should be user-friendly. Only then, you can make the best use of the features present.
Are you planning to use the best dual fuel generator as the remote source of power for powering one or a couple of low-wattage devices at a time? Otherwise, are you planning to use the power from the generator for powering multiple devices with high energy needs at the same time? Otherwise, are you planning to connect the generator to the circuit breaker in your home for powering the entire house during a power outage? When you can find the right answer to these questions, you can figure out the receptacles you require. For instance, some generators come with many 120V outlets, while some come with 120V/240V twist-lock outlets. Based on your requirement, you will have to shortlist the generator with the right output.
5. Level of Noise
You might be aware that any combustion engine will obviously make noise. You cannot find anything like a silent gas engine for sure. The reason is that they depend on dozens of tiny little explosions in order for producing energy. When you compare one power generator to another, you should look for noise ratings on the technical specs page. You can find this information in decibels on the specification page. Are you planning to use the generator at home? If so, you should look for a unit that can function as quietly as possible. The reason is that a noisy generator can fuel tension with your neighbors.
Are you planning to use the fuel generator even when you will be on a trip? If so, it is better to consider the portability of the generator. Most generators come with wheels for portability. However, even though some of them have wheels, it will be hard to move them due to excess weight. So, do not forget to consider the weight and portability of the generator before you shortlist.
7. Electric or Recoil Start
When you compare portable generators with dual fuels, it is better to check the kind of start it offers. If you are particular about the traditional way of starting, you can go for a generator with a recoil start. But, if you wish that you should find it easy to start the generator, it is better to look for a unit with an electric start. Also, the good thing about electric start generators is that they come with an internal battery to store additional electricity. But, recoil start being a traditional starting method is a dependable technology. The thing to remember here is that at present recoil start technology has improved a lot. So, you need not have to worry that you will have to spend a lot of your energy. So, decide one of these based on your personal preference.
In addition to these features, when you intend to buy a dual fuel generator, do not forget to check the fuel efficiency and safety features before deciding on a particular model. Naturally, you should look for durability and positive reviews before deciding on a generator.

Portable power stations provide a hassle-free operation. You just need to use the on-off switch for the same. Dual fuel generators with electric start buttons are also convenient. But if your generator comes with a pull-coil mechanism, you need additional efforts to start the engine.
Dual fuel generators can provide more output compared to portable power stations. They can be used for high-power requirements in construction sites, field activities, etc. Power stations cannot supply such higher outputs. So, they are mostly used for home purposes and recreational activities.
A traditional dual fuel generator is slightly heavy when compared to portable power stations. The latter is convenient to carry. Dual fuel generators can cover for long, whereas portable power stations can cover for a few hours.
Dual fuel generator vs portable electric generator
A portable electric generator is compact and lightweight. You can easily transport this equipment without having to worry about its parts. A dual fuel generator is slightly complex when compared. This equipment is also portable but can cause fuel leakages.
Dual fuel generators are usually intended to deliver high output powers. So, they can cover blackouts at construction sites, on-field activities, homes, and different scenarios for a long time. Portable electric generators, on the other hand, cannot deliver such outputs. So, they can cover some home appliances. These are specially meant for recreational and outdoor activities.
Portable electric generators are affordable and come with little or no assembly. Dual fuel generators are a little complex and are 10-15 percent more expensive than traditional generators.
As the output from a portable electric generator is low, it cannot run high-power appliances like refrigerators. These appliances require a higher surge, which can be supplied by dual fuel generators.
Portable electric generators can be easily transported in your car. Dual fuel generators are also portable but require additional care.
Dual fuel generator vs portable propane generator
One significant difference between a portable propane generator and a dual fuel generator is the fuel. The former can only run on propane. Dual fuel generators can run on two different fuels, either in a combination or one alone. So, you have a lot of fuel options for the latter, as you can use natural gas, diesel, gasoline, propane, or anything based on your generator’s requirement.
A portable propane generator requires you to store propane fuel carefully. Storing in bulk quantities may stagnate the fuel and damage your equipment. Dual fuel generators allow you to play with the combinations. So, you don’t have to stock up a single fuel all the time.
Portable propane generators are less expensive and lightweight. Dual fuel generators are more expensive than propane generators. They are heavier and more complicated too.
Dual fuel generators can backup for a long time. Portable propane generators cannot run as long as dual fuel generators do. Their power outputs are also low.
Portable propane generators emit noises and greenhouse gases. Dual fuel generators emit low noise when compared. Their greenhouse emissions are also low. Dual fuel generators are considered an eco-friendly option over portable propane generators.
Dual fuel generators usually have more outlets compared to portable propane generators. Their versatility helps connect various devices and appliances at once. Portable propane generators usually come with limited outlets.
