Today, it’s hard to imagine our life without electricity. However, in case of a power outage or if you happen to get off the grid for a while, a generator could be a great solution to keep your tools and appliances working. Although running a generator on propane is usually less efficient, propane is a much cleaner-burning fuel than gasoline, which is better for both the environment and the generator itself. Propane is also easier to store and cheaper than gas.

However, finding the best propane generator is not an easy task, as it is almost impossible to find a model that solely runs on propane. Therefore, we not only tested propane generators, but also added dual-fuel models on our list. We carefully tested starting and running wattage of generators to make sure all your power needs are covered. We also paid attention to the efficiency of running on propane and runtime, as well as noise level and generator starting system, as all these features are important in terms of ease of use and comfort.

Buying Guide

You are finally convinced with the idea of buying a propane generator, but what’s next? Ideally, you should have vital information about portable generators to help you make an informed choice about the type of generator that will suit your needs. There are two types of generators and these include the gasoline-fueled and propane-fueled generators. Both of these two types of generators have their pros and cons. People, for example, go for gasoline-powered generators because they have a higher power output as compared to the ones that run on propane. On the other hand, propane generators are popular for their longer runtime, clean power output and safety.

Why get a propane generator?

Propane generators are certainly preferred over their counterparts for a couple of reasons. First, propane is stored in individual and bulky cylinders, which means that it will be available when the gas pumps aren’t running. Unlike gasoline, the shelf life of propane is considered to be infinite. Gasoline will easily degrade after a couple of months of not using the fuel. A propane generator will stay idle for months and it won’t have carbon deposits like a gasoline generator. Your environment footprint on this earth should also be a pretty important reason why you should get a propane generator. If you are an environmentalist or just mind about the environment, then propane generators should be your first choice.

Propane burns in a cleaner way and this makes it an environmentally-friendly choice. Also, it has lower operating costs than gasoline-powered generators. After all, you don’t want to purchase something that breaks the bank.

How do you plan to use your propane generator?

There are a lot of reasons why you should purchase a propane generator but it is equally important to factor in how you plan to use the propane generator. You do not want to buy a fancy propane generator only to realize that it does not suit your needs. For example, many people will rush to purchase a propane generator during an emergency and buy the first choice they see. The problem is that it might be impossible for you to use your AC when you are using other appliances due to the power output.

What should you consider here? You should first determine what are your home essentials that should obviously be powered. This may include the lights, air conditioner, sockets etc. It is also important to review your appliances and the power they will consume. Some people purchase their propane generators for outdoor use or to power their RVs. The best propane generator should have your ideal power capacity and the desired outlets for this to ensure that for the money spent, you own the best whole house generator or the best RV generator. The Pulsar PG5250B is a good choice if you are looking for a propane generator with multiple outlets.

How much power do you need?

Power output is perhaps the most important thing that you should consider when looking to purchase a propane generator. Remember that your generator is your back up and it should have enough power output to power all your appliances and machines. A good way to approach this is to calculate all the total wattage that you want to power in the event that there is an outage. Before you remove your calculator, please note that some appliances in your home might consume more power when they are cycling on. These appliances include your refrigerator, air conditioner or pumps. Calculate all the wattage that even the hardwired appliances consume but if you are unable to do this then hiring the services of an electrician is a great idea.

After you get an idea of the total wattage you need per hour, you can easily find out if the generator will be suitable for your needs or not.

For those who live in areas that are prone to frequent or long-lasting power outages, the Pulsar PG5250B and the Champion Power Equipment 76533 are great choices, especially when you consider the fact, that the last one mentioned model is considered to be the best generator under $500.

For how long will your generator run?

A generator is only as good as its running time. There is no need to have a powerful propane generator that runs for about 5 house. However, the runtime that you should choose will ultimately depend on what you are powering and for how long your electricity will be out. For example, if you only need to power your workstation then you can choose a propane generator with a shorter runtime.

The Westinghouse WGen3600DF is a great choice for those who are looking for a longer runtime. It can run for about 18 hours when it’s running on gasoline but will run for about 20 hours when it is using propane. This is especially useful if your area is prone to power outages due to emergencies or natural calamities. The Pulsar PG5250B will also offer you a longer runtime as it runs for about 15 hours.

How noisy is a generator?

Best Propane GeneratorBest Propane GeneratorBest Propane GeneratorOne of the many reasons why people do not like generators is because of their noise. Fortunately, thanks to advances in technology you can easily find a generator that does not make a lot of noise when running. Your neighbors do not also want to be woken up at the middle of the night because of your loud generator. There has also been a myth that the loudest generators produce the most power, which is very incorrect.

Noise levels are measured by decibels and the lower the decibels the lower the noise. The Champion Power Equipment 100263 was found to be the propane generator with the lowest noise levels at 59 dB(A). The FIRMAN H03652 Hybrid Series was also found to have a relatively lower noise level at 67 dB(A), and if you are looking for the best Firman generator with a budget-friendly price, then it’ll be you number one pick,  while the Pulsar PG5250B was found to have higher noise levels at 78 dB(A).

Conventional vs inverter generator

There are two types of generators in the market. These include the inverter alternator generators and the conventional generators. What is the difference? You are probably wondering. Well, inverter generators come inside a casing that reduces their noise levels while conventional generators are probably what you have in mind. They have an open frame and may produce a higher noise level.

Inverter generators are known to have some advantages over the conventional ones. For example, they are quieter and more fuel-efficient than the conventional ones. They are also compact and tend to be lighter than the conventional generators.

On the other hand, conventional generators also have some upsides that the inverter generators do not. They are often cheaper than their counterparts, which means that you won’t break the bank to have a backup power source. Also, they often produce more power output but they are louder than the inverter generators.

Safety considerations

We can’t make enough emphasis on the importance of safety when purchasing your first generator. Generators that are powered by gasoline are known to be dangerous since gasoline degrades and produces poisonous carbon gases if it is left idle for a few months. Propane generators are always considered to be a safe choice. This should be your first decision when purchasing a generator. Should you buy a gasoline-powered generator that has more output or a propane generator that is safer?

Propane generators are recommended but there are additional features that manufacturers today are adding to generators to ensure they are safe. The Westinghouse WGen3600DFChampion Power Equipment 100263 and one of the best Sportsman generatorsSportsman GEN4000LP are examples of generators with an automatic low-oil shut off. The Champion Power Equipment 76533, on the other hand, has a Volt Guard™ surge protector that prevents overloads in the generator.


  • Before you choose the generator, it is first important that you know your power priorities. How do you do this? Make a list of what you don’t want to go out with when the power is out and calculate their watts.
  • Secondly, you need to know the type of generator that will be suitable for your needs. Do you want a portable generator, a home standby generator or an inverter generator? Knowing the pros and cons of each will save you a lot of stress in future.
  • Finally, get a generator that allows you to check the level of fuel through an easy to use fuel gauge. You will appreciate this feature during longer power outages.


Propane generators are known to be more efficient and budget-friendly as they last longer than gasoline generators.

Typical propane generators produce about 50 to 65 dB(A).

You are much likely to have a bigger generator with more output and this means that you will have more runtime during outages.


Our top choice is Westinghouse WGen3600DF, which we liked because of its powerful engine, longer runtime and overall safety features. It also has more powerful models for those who feel that the output is not enough. The second choice is the Champion Power Equipment 100263, an inverter generator that is not only one of the quieter generators on the market but is also a top performer. And for those who don’t want to spend more for a dual-fuel option, we included the Sportsman GEN4000LP in our review. This generator is more affordable than its dual-fuel competitor and runs efficiently on propane.
