Buying Guide for Dual Fuel Generators
Power Output and Fuel Type
Your first consideration should be wattage. Starting watts indicate the surge power needed to start motor-driven appliances like refrigerators or air conditioners. Running watts reflect the continuous power a generator can supply. Dual fuel models typically have different outputs for gasoline versus propane, with gasoline often providing a slight power advantage. Ensure the unit you choose can handle the combined wattage of your essential devices.
Fuel flexibility is the core benefit. Gasoline is widely available, while propane stores indefinitely and burns cleaner, which can lead to less engine maintenance. A good dual fuel generator allows seamless switching between sources without shutting down, a feature found in models like the Generac 8,250 Starting Watt Dual Fuel Portable Gas. For more on powerful traditional options, see our review of the best Briggs & Stratton open frame portable generators.
Inverter Technology and Noise Level
Inverter generators produce clean, stable power that is safe for sensitive electronics like laptops and smartphones. This technology also allows for quieter and more fuel-efficient operation. The Briggs & Stratton 4375W Dual Fuel Open Frame Inverter Generator, for example, operates at a neighborhood-friendly volume.
If you plan to use your generator in a campground, RV park, or residential area, a lower decibel rating is crucial. Look for models that specifically advertise quiet operation. Inverter models are generally quieter than conventional open-frame generators, making them ideal for these scenarios. Discover more about this technology in our guide to the best Briggs & Stratton portable inverter generators.
Runtime and Portability
<!–Runtime determines how long you can go between refueling. It is directly affected by load; a generator running at 25% load will last much longer than one at 50% or 75%. Check the manufacturer’s runtime estimates for both gasoline and propane at various loads. A larger fuel tank, like the 5-gallon tank on the Briggs & Stratton 6250W model, naturally supports longer operation.
Portability features are equally important. Consider the unit’s weight and whether it includes wheels and a folding handle. A generator that is difficult to move defeats the purpose of being portable. Even heavier models become manageable with sturdy, never-flat wheels and a well-designed handle system for transport over various terrains.
Safety and Convenience Features
<!–Modern generators prioritize user safety. Carbon monoxide detection and automatic shutdown, such as Briggs & Stratton’s CO Guard or Generac’s COsense, are vital for indoor air safety if the generator is used incorrectly. Low-oil shutdown and overload protection also prevent engine damage and electrical issues.
Convenience is about easy operation. Electric start with a key or push-button eliminates the struggle of a pull-cord, especially in cold weather. A clear control panel with multiple outlet types, including household GFCI, RV-ready TT-30, and USB ports, adds significant utility. For models emphasizing easy startup, explore the best Briggs & Stratton electric start generators.

Frequently Asked Questions
What are the main benefits of a dual fuel generator?
A dual fuel generator offers flexibility and preparedness. You can use whichever fuel is more available or cost-effective at the time. Propane has a long shelf life and burns cleaner, while gasoline often provides slightly higher power output. This versatility is invaluable during extended power outages or fuel shortages.
Can I run a dual fuel generator on both gasoline and propane at the same time?
No, you cannot run a standard dual fuel generator on both fuels simultaneously. These units are designed to operate on one fuel source at a time. They feature a selector switch or dial that allows you to choose between gasoline or propane. You must switch the fuel selector and let the engine consume the remaining fuel from the previous type before it runs on the new one.
Are Briggs & Stratton dual fuel generators good for powering sensitive electronics?
Yes, but specifically, you should look for their inverter models. Generators like the Briggs & Stratton 4375W Dual Fuel Open Frame Inverter use advanced inverter technology to produce clean, stable power with low total harmonic distortion (THD). This pure sine wave output is safe for laptops, phones, medical devices, and other sensitive electronics, unlike the ‘dirty’ power from conventional generators.
How do I calculate what size dual fuel generator I need?
Start by listing all the appliances and devices you need to power simultaneously. Add up their running wattage requirements. Then, identify the single appliance with the highest starting wattage (often 2-3 times its running wattage). Your generator’s running wattage must exceed the total running wattage, and its starting wattage must exceed the highest appliance starting wattage. Always allow for a safety margin of 10-20%.
