Buying Guide of Dual Fuel Generator

A dual fuel generator is a versatile option for those who want a backup power source for their homes, businesses, or outdoor activities. When buying the best dual fuel generator, there are several factors to consider:

Power output

 To determine the amount of power you need from a generator, you should make a list of all the appliances and devices you plan to run and their wattage requirements. You can find this information on the label or in the user manual of each item.

Once you have a list of all the devices and their wattage requirements, add up their total wattage to get an estimate of the amount of power you need from the generator.

When shopping for a generator, look for one with a power output that matches or exceeds the total wattage of the devices you plan to run. It’s important to choose a generator with the right power output to avoid overloading the generator, which can damage both the generator and the devices you’re running.

Fuel efficiency

Dual fuel generators have the capability to run on either propane or gasoline. When deciding between the two fuel options, it’s important to consider their respective fuel efficiencies.

Propane has the advantage of burning cleaner and being storable for an indefinite amount of time, but it may be less efficient than gasoline. Gasoline, on the other hand, is widely available and may be more fuel-efficient than propane.

Ultimately, the choice of fuel depends on the user’s priorities and the availability and cost of the fuel sources.

Run Time

The runtime of a generator at half-load and full-load can vary depending on the specific model and its fuel source. However, in general, generators that have larger fuel tanks or are designed to be more fuel-efficient tend to have longer runtimes. It’s important to note that running a generator at full-load for an extended period of time can also decrease its runtime. It’s recommended to consult the manufacturer’s specifications for specific runtime information and to properly maintain the generator to ensure optimal performance.


Portability refers to the ease with which a dual fuel generator can be moved from one location to another.

If you intend to use a dual fuel generator for outdoor activities like camping, it is essential to choose a model that is lightweight and easy to transport. This will make it easier for you to carry the generator to your destination and move it around as needed.

Factors that can affect a generator’s portability include its weight, size, and the presence of wheels or handles for easy transportation. Additionally, it’s essential to consider the generator’s fuel type and capacity, as heavier and larger fuel sources can impact portability as well.

Noise level

The noise level of a dual fuel generator is typically measured in decibels (dB). A generator with a noise level of around 50-65 dB is considered to be relatively quiet and suitable for most residential and outdoor activities.

However, if you require an even quieter generator, there are models available with noise levels as low as 40 dB or even less, which is comparable to the sound of a library or a quiet conversation.

Keep in mind that the power output of a duea fuel generator can impact its noise level, so it’s important to choose a generator that provides the necessary power while still meeting your noise level requirements.

Brand reputation

Brand reputation refers to the overall perception that customers and the public have of a particular brand based on its products or services, customer service, and other factors such as corporate social responsibility and marketing.

It is important for businesses to maintain a positive brand reputation to attract and retain customers, as well as to build trust and credibility with the public. Researching and selecting a reputable brand with good customer service and reliable products can help ensure a positive customer experience.


 When considering price in the context of purchasing a dual fuel generator, it is important to keep in mind that the cost of the generator is just one factor among many that should be taken into account.

Other factors to consider include the intended use of the generator, its power output and fuel efficiency, the level of noise it produces, and the overall reliability and durability of the generator.

In terms of price, it is important to balance your budget with your needs and expectations for the generator. While it may be tempting to opt for a cheaper generator to save money, a lower-priced dual fuel generator may not provide the necessary power output, fuel efficiency, or durability to meet your needs over the long term. On the other hand, a more expensive generator may offer features and capabilities that you do not require for your particular application.

To find a generator that provides good value for money, it is important to do your research and compare different models based on their specifications and customer reviews.

Look for generators that are known for their reliability and durability, as well as those that offer the necessary power output and fuel efficiency for your specific needs. Consider purchasing from a reputable manufacturer with a strong track record of producing high-quality generators.

Ultimately, the goal should be to find a generator that offers the right balance of features, performance, and price to meet your needs and budget. By taking the time to carefully evaluate your options and make an informed decision, you can ensure that you get the most value for your money and are satisfied with your generator over the long term.
