Why Generators Dual Fuel Systems Are a Game Changer

Picture yourself having the ultimate power source at your fingertips, capable of adapting to your needs and providing uninterrupted energy, no matter what. Sounds too good to be true, right? Well, brace yourselves as we introduce you to the fascinating world of dual-fuel generators! In this article, we will explore how these versatile powerhouses work, guiding you through the essential factors to consider when buying one and unlocking the secrets behind their incredible performance. So, let's start and fuel your curiosity!

How Does a Dual Fuel Generator Work?

A dual fuel generator is a versatile power source that can operate on two different types of fuel, typically gasoline and propane. The primary advantage of this type of generator is the ability to switch between different fuel sources depending on availability, cost, and personal preference. The generator is equipped with a fuel selector switch that allows the user to personally select the desired fuel type and a specially designed carburetor that can handle both gasoline and propane without the need for any modifications.

The generator's engine is designed to run on either fuel type by adjusting the air-to-fuel ratio for optimal combustion. When operating on gasoline, the generator uses a traditional fuel system with a fuel pump, fuel filter, and injectors to deliver gasoline to the engine. When switched to propane, the generator draws vaporized propane from a connected tank through a pressure regulator, which maintains a consistent pressure for the propane as it enters the carburetor. The carburetor then mixes the propane with air, creating a combustible mixture that is ignited by the spark plug, generating power. This dual-fuel capability increases users' flexibility and reliability, ensuring a continuous power supply even if one fuel source becomes unavailable.

What to consider when buying a dual fuel generator?

When purchasing a dual fuel generator, there are a few key factors to consider to ensure that the device you choose meets your specific needs.

Fuel Capacity

Dual fuel generators come in various sizes and fuel capacities, with most models being compatible with liquified petroleum gas (LPG) tanks and unleaded gasoline fuel tanks. The fuel tank capacity typically ranges between 3 gallons (11L) and 8.5 gallons (32L), depending on the generator model. When purchasing a dual-fuel generator, it's important to consider its fuel capacity, as it determines how long the generator can run without needing a refuel. A larger fuel tank allows for extended run time, which is especially important during emergencies or extended power outages.

Power Output

The power output of a generator plays a crucial role in determining the number of devices and appliances it can support. Power output from dual fuel generators can vary significantly, with the most powerful generators producing up to 12,500W, while smaller models reach around 5,000W. To put this into perspective, the average U.S. home consumes nearly 30,000W daily. Although these generators may not be able to power every appliance in your home continuously, they can provide support during emergencies and keep your essential devices running.

Having a reliable backup power solution for your home that can function effectively in any situation is very crucial. Note that blackouts can disrupt access to natural gas infrastructure, and natural disasters may render other fuel sources unavailable. Dual-fuel generators solve these challenges by providing dependable backup power using multiple fuel types.

Noise Levels

Generators can be quite noisy, so it's crucial to consider the noise level of the dual-fuel generator you're purchasing. Although achieving a completely silent dual-fuel generator is nearly unattainable, remarkable advancements have been made in recent years. Some compact models feature a decibel level around the mid-40s, comparable to a home's typical background noise.

On the other hand, the quietest high-quality, large-scale generators usually reach up to 75 decibels, just slightly louder than a vacuum cleaner. Remember, the aim is to look for generators with low decibel ratings or built-in noise reduction features to minimize disturbance to you and your neighbors.

Portability and Size

Portability and size are crucial factors to consider when it comes to emergency equipment. Generally, the power output of a generator is inversely proportional to its size. You can find small generators, roughly the dimensions of a sizable purse, weighing around 40 pounds (18 kg), but their power output typically does not exceed 3,000W. On the other hand, more substantial generators can weigh up to 250 pounds (113 kg) and are equipped with wheels for easy transport. These larger generators are capable of producing well over 10,000 watts.

Just keep in mind that portability and size will always be significant factors depending on your intended usage. Smaller, lightweight generators with wheels and handles are ideal for camping or job sites, while larger, stationary generators may be better suited for home backup power.

Engine Efficiency

When considering fuel consumption and overall performance, engine efficiency plays a crucial role, particularly if you have a plan to use it frequently or for long durations. Dual fuel generators, which serve as an intermediate option between traditional diesel-powered generators and clean, renewable energy devices like solar generators, typically offer superior engine efficiency compared to generators from just a decade ago.

Dual fuel models boast greater efficiency than their older counterparts, as they possess the ability to switch between gasoline and propane. This versatility not only enhances their performance but also contributes to a more environmentally friendly operation. By opting for a dual-fuel generator, you can enjoy the benefits of improved engine efficiency, reduced fuel costs, and decreased emissions, making them an excellent choice for various applications.

Safety Features

When purchasing a dual-fuel generator, it is crucial to consider the safety features in the design. These features can range from built-in circuit breakers and overload protection, which prevented damage to the generator and connected devices, to automatic low-oil shutdown and carbon monoxide detectors, which protect you and your surroundings from potential hazards. Additionally, look for generators with sturdy frames and grounding options to ensure stability and safe operation during use.


Lastly, of course, we have the budget. Now, the price of a dual-fuel generator can vary significantly based on its size, power output, and other features. To select a generator that falls within your budget, decide how much you are likely to spend and rank your needs, such as power capacity, portability, and noise level. Remember that buying an efficient and durable generator will save you hard cash in the long term by lowering maintenance expenses and offering economical fuel use.


To wrap up, dual fuel generators provide adaptable and efficient power solutions for a wide range of uses, from home backup power to outdoor escapades. By taking into account aspects such as fuel capacity, power output, noise levels, portability, engine efficiency, safety features, and your budget, you can find the ideal generator to suit your requirements. The capability to switch between gasoline and propane offers flexibility in fuel availability and cost, making sure you always have a reliable power source at hand. So, whether you're gearing up for emergencies, powering your workplace, or reveling in nature, a dual fuel generator is a wise investment that ensures a portable power source and peace of mind. So, what are you waiting for? Equip yourself with a dual fuel generator and experience the convenience and reliability that comes with this versatile power solution!
