Top 15 Best Portable Propane Generators in 2020

The best portable propane generator will power your electrical appliances without any power fluctuations. As the name suggests, these generators are powered by propane.

They are classified into three groups; single fuel, bi, or tri-fuel. Single fuel means they run on propane only; bi-fuel means they run on propane and diesel or gasoline, and tri-fuel means they run on propane, gasoline, and diesel.

If you want to purchase a generator for your RV, home, or use on worksite, choose a generator that runs on propane.

Propane is another name for Liquefied Petroleum Gas (LPG).  In this guide, we are going to review 15 best propane generators and other factors to consider when choosing a generator that runs on propane.

How Efficient Are Propane Generator

Propane is considered the cleanest fuel, while gasoline is the most convenient, and diesel is termed as the most powerful web.

A propane generator consumes an average of 3.44 gallons per hour, 0.75GPH for gasoline, and 2.9GPH for diesel. From the figures, it’s easy to conclude that you need to burn more propane than diesel or gas to produce an equal amount of electricity.

But since propane contains a higher-octane rating compared to gasoline (104-112 for propane and 87-92 for gasoline), it makes for more horsepower.

Additionally, a propane generator requires minimal maintenance due to low contamination from carbon and hence, a longer lifespan.

Propane (C3H8) burns in oxygen to release carbon dioxide (CO2) and water, making it a clean fuel that’s safe for the environment and humans.

Benefits of the Best Portable Propane Generators

There are several benefits of owning a propane generator that you cannot get with gasoline or diesel-only generators. They include

Less noise & longer shelf life

Propane generators are much quieter than gasoline or diesel power generators.  If you want something that won’t sound like you have a mini-launch pad in the backyard, we highly recommend the gensets in this review. One of the quietest propane-powered generators is the FIRMAN H03652.

Additionally, propane doesn’t expire when stored properly.  This makes propane the right fuel for you, especially when you need backup power.

Availability and clean-burning

In case of a power outage, some gas stations may not be able to pump fuel. Since propane is stored in cylinders and large tanks, it’s readily available even in the event of a power outage.

In addition, propane burns clean and less contaminant to the environment than gasoline or diesel fuel. It produces less carbon monoxide compared to gas/diesel gensets.
