Are you in the market for a propane generator? If so, you’ve come to the right place. This buying guide for the best propane generators in 2023 will provide you with the essential information you need to make an informed decision. We’ll cover everything from the different types of propane generators available to the benefits and drawbacks of using a propane generator to which brands offer the best propane generators.

What Is a Propane Generator?

A propane generator is powered by propane, a clean-burning liquefied petroleum gas (LPG). Propane generators generally provide backup power during outages and in recreational vehicles such as trailers and boats.

Most propane-powered generators are dual-fuel, but several single-fuel and tri-fuel generators also exist. Besides propane, the other types of fuel used include gasoline and natural gas, with dual-fuel propane generators getting their power from either propane or gasoline.

The versatility of dual-fuel propane generators is also worth mentioning. With a dual-fuel system, you can easily switch between gasoline and propane without turning off the generator. And since propane is an affordable fuel option compared to gasoline, this makes them a cost-effective choice in the long run.

But one may ask, how do propane generators compare to gas/diesel-powered generators?

Benefits of Propane Over Gas/Diesel

Propane generators are becoming increasingly popular for a variety of reasons. Unlike their gas and diesel-powered counterparts, propane generators use an efficient, clean-burning fuel that is both renewable and cost-effective.

Generally, propane burns cleaner than gas. The lack of exhaust fumes makes propane generators a good choice for various uses. Propane can burn for longer hours than gasoline and also has a longer shelf life, which makes it ideal for use in backup power systems.

The clean-burning mechanism of propane generators also makes them run quieter compared to their gas/diesel-powered generators of equal output. For instance, some propane-powered generators register noise levels as low as 50dB. In comparison, traditional generators may register noise levels of up to 100dB, primarily because they constantly run at a higher RPM.

Finally, propane is a much safer fuel option than gasoline. It is non-toxic, non-explosive, and does not generate sparks when used. This makes it less risky to use in enclosed spaces and more suitable for homes and RVs. 

When You Are Looking for a Propane Generator, Take Note of the Following:


Calculate the total wattage by adding the wattage requirements of each appliance or tool you plan to use with the generator. This will help you determine the size of the generator you need. It is important to buy a generator with a higher wattage than the total wattage of all the appliances you wish to run.

Size and Weight

Portability is critical since you don’t want to choose something too big or heavy that can’t be moved around easily. Therefore, it is important to have something that fits your mobility requirements.

Noise Emission Level

If you plan on using the generator in an area with many people, you don’t want to disturb them with loud noises. Therefore, it would be best to consider generators with low noise levels.

Purchase and Maintenance Cost

Propane generators can be relatively expensive, depending on the size and power output. Make sure to shop around and compare prices to get the best deal. To save money in the long term, look for generators with low maintenance costs, good warranties, and regular servicing options.

Fuel Efficiency Ratings

Generators that offer better fuel efficiency ratings tend to last longer and will save you money on fuel costs.
