Top 7: Best Propane Generators Review

Compared to other fuel types, propane is considered as a limitless generator fuel ideal for those looking for reliable and infrequent emergency power back up.

Unlike gasoline which goes stale after staying inactive for long, liquid propane has an infinite shelf life, and this makes it’s a good investment for someone who might be needing backup power in the future and doesn’t want the hassle of shopping for gasoline.

Again, unlike gasoline, the best propane generators do not suffer from cold starting. Propane burns cleanly does not generate gum deposits, and thus easier to cold start during emergencies.

The final reason is that propane is a less polluting fuel and will produce reduced carbon monoxide. This makes the propane generators ideal for those who care about air quality.

Still, with all the numerous benefits of propane, finding the best propane generator feels like a Herculean task. The good news is; we have prepared a comprehensive propane generator review that will highlight the best generators in the market.

Here we shall explore the features plus benefits of top 7 propane generators, and by the end of the article, you should have made a decision on which one will suit your needs.

What to Look For While Buying the Best Propane Generator?

You already have a list of the best propane generators. Still, picking the best one is a daunting task, especially if you do not know where to start.

Fortunately, we have compiled a comprehensive propane generator buyer guide that will get you started.

But before then, let’s look at the three types of propane generators;

3 Types of Propane Generators

Home Standby Generator

The home standby generators are on the higher side of the scale, and usually, need installation by a professional.

They are designed to turn on automatically when the power goes out, and they usually run a self-diagnosis to let you know when maintenance is required.

The home standby generators are flexible enough and will allow you to use either propane, gasoline or natural gas, and they range from around 5,000 to 20,000 watts.

Portable Generators

Again, like the home standby generators, portable generators are flexible and can run on either propane or gasoline.

However, they provide a lesser amount of wattage, anywhere from 3000 watts to 8500 watts.

They are lightweight, and as their name suggests, they're easier to move around your home.

A majority of the portable generators have an electric starting and may or not have a battery included.

Inverter Generators

Inverter generators have a more complex engine compared to the latter two, and also a lot quieter.

Unlike the latter unit which uses a conventional engine, inverter generators are designed to throttle up and down to match demand/load rather than run at maximum power the entire period.

Thus, they run more efficiently, and generate “clean” power, which is ideal for powering sensitive appliances and they usually give off fewer harmful emissions.

Things to Consider when Purchasing a Propane Generator


What are your power needs?

The type of generator you will need will depend on the appliances you are planning to run off it.

For instance, if you are planning to power up your entire household during an emergency, you would want a high-powered propane generator that can output at least 5,000 watts. The output should be even more if you have a water pump or an energy-hungry heating system.

On the other hand, if you are trying to power your RV, a lesser output, say a 3000-watt generator should be sufficient.

To sum up, you should always consider your power needs, i.e., the total wattage of the appliances you look forward to power before purchasing a propane generator.

Running Time

Runtime is equally as important as wattage, depending on your application.

For example, if you are looking to power your home and want everything to run close to normal, or usually have power outages extending for long hours, you would want a generator with at least a runtime of 10-12 hours at half power.

However, if you have an RV and only need power for a few short bursts of times, for example in the morning and evening, then runtime should not be a major consideration.


Portability is essential depending on your generator uses. For instance, If you plan on using your generator for tailgating, or camping, having a lightweight generator, with wheels and handles is critical for easy movement.

Ease of Use

Always consider how easy it is to use a generator.

As much as the installation process might be quite a hassle, you should always be in a position to operate your generator easily.

Check on the control panel, start mode and the general outlay of the unit.


Most of the generators usually work in the open and therefore need to withstand the wear and tear.

While it's hard to judge the durability of a generator, it's always a good idea to choose a unit constructed from durable materials such as metal.


If you are looking to buy a generator, the price will keep you in line.

Sure, the price may range from a few hundred to thousands of dollars. It's therefore recommended that you choose a unit that is within your budget range.

More importantly, strike a balance between cost and quality; find the sweet spot that will address your power needs while still being favorable to your pocket.

Top Generator Brands

After thorough research, we were able to shortlist the best generator brands in the market based on their popularity, reviews and longevity in the market.

Most of these brands are household names and usually manufacture high-quality products, and so getting a product from any of these would guarantee quality.

However, as we had mentioned earlier, never overlook the new and upcoming brands.

These brands include:

Benefits of Using Propane to Run your Generator

Gasoline and propane are two of the common generator fuels we have on the market.

So, between these two, why is propane considered a superior fuel, or rather why would you want to run your generator on propane as opposed to gasoline?

  • Propane, unlike gasoline, does not spoil; it's stable and has a long shelf life, meaning you can buy it and store it for some time before using it. This makes propane, particularly an ideal solution for power back up in case of emergencies.
  • Propane is an eco-friendly fuel, thanks to its cleaner burn. While it still doe generate carbon monoxide and cannot be used indoors, it’s less polluting as it generates little amounts of carbon monoxide and the friendliest fuel to use for your back up road trips and at home.
  • Propane is a cost-friendly option, and moreover, it runs for longer meaning you will not require frequent refueling
  • Propane fuel tanks are easier to find, and besides, they are highly portable and convenient for places with no electricity
  • Propane, being a hands-off type of fuel, it’s one of the safest power fuels in the market. With a propane generator, you will never have to worry about refueling it yourself.

Propane Generator Vs. Gas Generator

Now, fuel aside, if you were to choose a propane generator and gas generator, which one would you consider?

Here are some of the reasons why a propane generator would be an ideal choice:

Easier cold starting for propane generators: Propane, unlike gas will not gum up or produce unwanted gases even if left idle for months. This is contrary to gas generators, which are a little hard to cold-start, especially if they have not been used for a while. In any case, gas usually gums the carburetors, and starting the generator might prove to be a task.

Propane generators are quiet: Generally, propane generators usually generate moderate engine noise compared to their gas-fueled counterparts. Besides, their emissions are compliant, generate cleaner output and last longer.

Propane generators are safe: Sure, gas generators are heavy-duty types are commonly used for powering power-hungry equipment. However, to do so, they need to burn fast, and this makes them prone to fire hazards.

Dual Fuel- I don't know whether you noticed something common on our list of the best propane generators 2020. All the generators listed are dual fuel, with an option of using either propane or gasoline. Propane generators, unlike gas generators, can always run with at least one other fuel type and this makes them a reliable and efficient form of power source.
