What To Look For In A Dual Fuel Inverter Generator

When considering a dual fuel inverter generator, it’s important to look at factors such as power output, noise level, fuel type and efficiency, size and portability, runtime, and safety features.

Power Output

One of the key features to consider when choosing a dual fuel inverter generator is the power output. This refers to the amount of electricity it can generate, measured in watts (W).

The power output determines how many electrical appliances and tools you’ll be able to run simultaneously with your generator.

To determine your ideal power output, make a list of the appliances and devices you expect to use with the generator and add up their wattage requirements. Don’t forget that some appliances require more wattage at startup than they do during continuous operation – be sure to factor this into your calculations.

Once you have calculated your needs, choose a dual fuel inverter generator that can handle both peak and rated output of those devices while still offering maximum efficiency for longer runtime.

Noise Level

One of the critical factors to consider when choosing a dual fuel inverter generator is the noise level it produces.

For instance, the Champion Power Equipment 2500-Watt Gasoline/Propane Portable Inverter Generator stands out as one of the best quiet options available on the market today.

It generates only 53 dB, making it an excellent choice for people who want power without sacrificing peace and quiet. Another great option is the Pulsar Portable Dual-Fuel Quiet Inverter Generator that has a noise level of just 59 dB—perfect for those outdoor occasions where you need power but don’t want your conversations drowned out by a noisy generator.

Fuel Type And Efficiency

As a proficient generator user, I understand the importance of fuel type and efficiency when selecting the best dual fuel inverter generator for your needs. Dual fuel generators offer the flexibility to run on two types of fuel – propane and gasoline.

Gasoline is more readily available, making it a convenient choice for everyday use. However, propane is more cost-effective and offers better fuel efficiency, reducing operational costs over time.

Moreover, unlike gasoline which has a limited shelf life, propane can be stored indefinitely without losing its quality or potency.

In addition to choosing between these fuels based on their availability and pricing fluctuations in your region (remember: Durowatt), you should also consider factors like runtime rating and supported wattage output from different models before making an informed decision about purchasing one for camping trips or remote job locations (e.g., Champion Power Equipment 4550 Watt Recoil Start Dual-Fuel Powered Portable Generator).

Size And Portability

As a possible buyer looking for the best dual fuel inverter generator, size and portability are essential factors to consider. The weight of a generator can vary depending on the amount of power it produces, and this can have an impact on its mobility.

Generally speaking, portable generators that produce less power typically weigh around 50 pounds or less.

Portability also includes features such as handles or wheels to move the generator from one location to another with ease. It is important to note that these additional features can increase the overall weight of the device.

For example, DuroMax XP12000EH comes with wheels and folding handles despite being rated among the heaviest dual fuel inverter generators available at over 200 lbs due to its high wattage output capability up to 12kW while Westinghouse iGen4500DF’s lightweight design makes it easier for customers who prioritize portability without sacrificing quality and peak performance (rated at about 98 lbs).


One of the key factors to consider when purchasing a dual fuel inverter generator is its runtime. The runtime of a generator depends on the percentage of overall load and fuel type used.

For example, if you’re running your generator at 50% capacity, it will generally last longer than if you’re using it at full capacity.

When choosing a model that suits your needs, be sure to check the rated output and peak output wattage levels for an accurate assessment of runtime capabilities.

Additionally, consider where you’ll be using your generator – a portable option may not have as long or efficient of a runtime compared to more heavy-duty models designed for home backup power or job sites.

Safety Features

As with any device that generates electricity, safety should always be a top consideration when choosing a dual fuel inverter generator. Look for models with features like low oil shutoff and CO shutdown sensors to prevent damage to the engine and reduce the risk of carbon monoxide poisoning.

Some models also come equipped with GFCI outlets, which provide added protection against electrical shocks.

When it comes to fuel safety, choose generators that have been certified by relevant organizations like CARB, EPA, or CSA. Additionally, make sure the generator is equipped with quick connect valves for easy hookup to propane tanks and other accessories.

And finally, remember to keep your generator away from flammable materials and operate it in a well-ventilated area to minimize risks associated with combustible fuels.
