Best Dual Fuel Generator Reviews and Guide
Power outages and extended periods away from power sources are no problem when you have the best dual fuel generator on hand. These are the most popular applications, but anybody from construction workers and farmers to outdoor enthusiasts can benefit from a reliable generator when more power is required for a project or in a specific region.
There are numerous generator types available, but one with dual fuel capabilities has advantages over single fuel, solar, or electric generators.
A dual fuel inverter generator is a portable generator that can run on both gasoline and propane. It has an inverter system that converts the engine’s raw power into clean, reliable power that can power sensitive devices. Because these generators are frequently smaller and quieter than regular generators, they are a popular alternative for recreational use as well as emergency scenarios. They can switch between fuel sources on the fly, giving them greater flexibility and a longer run duration.
Today, we will present the top dual fuel generators on the market right now. You can browse our best options while learning about their vital qualities and gathering all of the necessary information.

Buying Guide for the Best Dual Fuel Inverter Generator
You must know a lot about dual fuel generators now that you’ve read about all of our recommendations for the finest dual fuel generators. You may perhaps have explored a few alternatives. However, while selecting a dual fuel generator, you must properly investigate its qualities and weigh their significance in relation to your application.
There is a good probability that some features provided in a particular product will not be required in your circumstance. This comprehensive shopping guidance is provided to avoid such a scenario. You can learn about each of the qualities in detail here and select which ones you require the most in your dual fuel generator. For an accurate selection, make sure you read the buying guide completely.
What to Consider When Buying a Dual Fuel Generator
Dual fuel generators feature specialized fuel tanks to store fuel because they are fueled by gasoline and propane. Each fuel tank has its unique capacity, thus they are not all the same.
This capacity is expressed in gallons. A 10-gallon tank, for example, can only carry 10 gallons of fuel at a time.
Having a large-capacity tank will benefit you in a variety of ways. You won’t have to bother about recharging the generator every now and then if you have a large fuel tank, and you’ll be able to enjoy uninterrupted power output. Remember that huge fuel tanks are only available as a premium option.
Watts are used to measuring the power output of dual fuel generators (W). Peak power output and operating power output are specified by manufacturers. The maximum amount of watts that a generator can supply at any given time is referred to as its peak power output. The average number of watts produced while use is the running power output.
Dual fuel generators range in power output from 1,000 watts to over 12,000 watts, depending on size and function. Some manufacturers may divide these figures further into propane peak and running power outputs and gasoline peak and running power outputs.
The breakdown of these figures is important since gasoline produces more watts than propane. Nonetheless, many dual fuel generator manufacturers do not differentiate between the two fuels when reporting peak and operating power output. Instead, they report the greatest statistics for gasoline, leaving you to guess the range for propane.
Rated and Peak Output
When purchasing a generator for backup power, you must consider the power available at the generator’s output. On each dual fuel generator, there are two separate output ratings: rated and peak output. However, these figures differ for gasoline and propane. As a result, each generator will produce four distinct output values.
This can be perplexing, but don’t be concerned. When purchasing a generator, if you only examine the peak capacity for both fuels, you will automatically receive a greater running watts output. For example, if you select a high peak value for gasoline, you will also receive a higher peak value for propane as well as higher running watts.
Dual-fuel generators start with one of two methods: a recoil cord or an electric starter. Using a cord, you pull the handle hard and quickly to provide the rotation required to start the generator. It needs more physical work but is more dependable. An electric starter is a one-button option that requires no effort to use, but it only works when its internal battery is charged.
Generators are quite noisy, which can be annoying if you maintain one (or several) in or near your home.
Generators become noisier as they produce greater power. (There are several exceptions.)
If you’re planning to keep your generator near your house or use it while camping in a quiet area, you’ll want to keep the noise down.
Higher-quality generators can typically (but not always) reduce the volume by utilizing thick shielding and other design factors. If pure power is your objective, you may have to live with the noise or find another means to reduce it.
Dual-fuel generators allow you to use propane, which generators process more silently than gas. Most dual-fuel generators produce between 50 and 90 decibels (about the same as a refrigerator) (about the same as a small-engine motorcycle).
This is an important consideration if you want to move the generator around for different purposes. If you are considering a heavy-duty generator, make sure you evaluate the size and weight of the generator.
Heavy-duty generators are often larger and heavier than low-powered generators. As a result, moving a heavy-duty dual fuel generator, especially while the fuel tank is full, might be difficult. On the other hand, if the generator is small in size, you will observe that the power capacity and fuel capacity are both reduced.
Each dual fuel generator contains an engine that uses gasoline or propane to generate energy. While various power output numbers may appear identical, fuel consumption will vary due to engine efficiency. Engine efficiency essentially shows how efficiently fuel may be spent to generate energy.
If the engine is inefficient, you will run out of fuel quickly. You will also be exposed to a large number of hazardous exhaust gases as a result of faulty fuel combustion. As a result, even if you choose a low-power engine, be sure it is economical in terms of fuel consumption.
Are dual-fuel generators worth it?
While dual-fuel generators are slightly more expensive than regular generators, they are more fuel-efficient, which reduces long-term expenditures. They’re also noticeably quieter when powered by propane rather than gas, which is ideal if you intend to keep it within earshot.
Dual-fuel generators are also particularly useful in situations where fuel is scarce. If you’re planning for a natural disaster, such as a hurricane, you should be able to use any fuel you can get your hands on.
What is the most powerful dual-fuel generator?
In terms of power, the sky is the limit in theory. In reality, the most powerful consumer-grade dual-fuel generators have a power output of roughly 12,000W.
Is it better to run a dual-fuel generator on gas or propane?
While gas produces more power, propane makes less noise and is less harmful to the environment. Having a dual-fuel generator allows you to select, or at least have access to, both fuel types.
How long will a dual-fuel generator run on propane?
That is entirely dependent on the size of your propane tank, the generator’s engine, and the amount of power it produces.
Our “best overall” pick, for example, can run for around seven hours at 25% power output capacity on a common 20-pound propane tank.
What is the difference between an inverter and a generator?
The electricity is generated by a generator, and the energy is stored and reconverted for usage by a power inverter. Inverters are built into almost all consumer-grade generators.
When camping or preparing for an emergency, a dual-fuel generator can be extremely useful. However, it is a significant investment, so make certain you choose the appropriate size generator for your needs. Bigger is clearly preferable when it comes to powering an entire house. However, for powering an RV or as a backup during a power outage, you might be better off with something more portable. Consider whether a more environmentally friendly power alternative, such as a solar generator, could provide you with the electricity you require while leaving a reduced carbon imprint.
