How To Choose The Best Dual-Fuel Generator?

Wattage Requirements

When choosing a dual fuel generator, the wattage capacity is a critical factor to keep in mind.

Start by evaluating the power requirements of your home or business during an outage to ensure the generator can handle the load. Calculate the total wattage of essential appliances and electronics you'll be running simultaneously to find the minimum running wattage needed.

If you want to be prepared for potential future power needs, consider opting for a model with slightly higher wattage for added flexibility.

Portability

If you're looking for a flexible power option, portability becomes essential.

Take into account factors like the generator's weight, whether it has a wheel kit for easy transportation, and comfortable ergonomic handles. Portable generators are perfect for camping, RV journeys, and mobile backup power needs.

Conversely, larger models with higher power capacity might be better suited for stationary backup power, be it at home or for businesses.

Choose the option that aligns best with your specific requirements and usage scenarios.

Noise Levels

Quieter generators are ideal for neighborhoods and places where noise could be an issue, offering a more pleasant experience for you and your neighbors during power outages.

Opt for models with low decibel ratings (50-60 dBs) or noise reduction features (such as mufflers, exhaust systems, smart throttling technology, or vibration isolation systems) to ensure quiet operation.

Which Brands Make The Best Dual-Fuel Generator?

Champion Power Equipment

Champion Power Equipment has established itself as a leading brand for dual fuel generators since its inception. With 20 years of experience, the company has perfected its technology, allowing their generators to run on gasoline and propane.

Unique features like Tri-Fuel technology and CO Shield® carbon monoxide auto shutoff system set Champion apart, ensuring safety and versatility for consumers.

FAQs

How does dual fuel generator work?

A dual fuel generator operates by utilizing a combination of two different fuels, such as propane, natural gas, diesel, or gasoline. It switches between these fuels either manually or automatically based on power requirements or fuel availability. The fuel is ignited through a spark plug, creating an explosion that converts into mechanical energy to generate power.

What is the difference between buying a generator with an inverter and a regular generator?

The main difference between buying a generator with an inverter and a regular generator lies in their power output and capabilities.

An inverter generator utilizes advanced technology to produce clean and stable power, making it suitable for sensitive electronics. Additionally, it is fuel-efficient and quiet.

Regular generators, on the other hand, provide raw power without the same level of precision and may not be ideal for delicate devices.

Is dual fuel better than electric?

The choice between dual fuel and electric generators depends on specific needs and circumstances.

Dual fuel generators offer the advantage of flexibility by running on multiple fuel sources, such as propane and gasoline. They also provide longer runtime options and can be useful in situations where fuel availability is limited.

Electric generators, on the other hand, are typically more efficient and produce cleaner power without emissions. They are suitable for indoor use, quieter operation, and may require less maintenance.

Can you run a dual-fuel generator only on propane?

Yes, it is possible to run a dual-fuel generator solely on propane by ensuring that the propane tank is properly connected and supplying fuel to the generator.

Is it better to run a dual-fuel generator on gas or propane?

The choice between running a dual-fuel generator on gas or propane depends on various factors.

Gasoline is more popular due to its availability, making it convenient for regular use. Propane, on the other hand, lasts longer and is easier to stockpile for emergencies.

How much propane does a dual-fuel generator use?

On average, a dual-fuel generator burns about 2 to 3 gallons of propane per hour.

How long will a dual-fuel generator run on propane?

A standard dual-fuel generator can run anywhere from 6 to 12 hours on propane.

Conclusion

In summary, the best dual fuel generator for you will depend on your specific needs. With this ultimate buying guide, we hope you can easily find one that meets your criteria while providing reliable power and performance no matter what types of fuels are being used. Thanks for reading!
