Best Propane Generators {Updated [month] [year]}

Power outages are a significant inconvenience for any home or business. At times, they can even be dangerous. In these times, we live in; most of our basic needs like food storage, work, and even entertainment rely on electricity.

Apart from solar panels, the best way to ensure that your home or business always has power even when the power grid goes out is by using a generator. Propane generators are by far the best generators since propane costs less than gasoline and can be stored for a long time without going bad.

Shopping for a propane generator can often be a daunting process since there are very many brands on the market, all marketing their product as the best. That, however, doesn't mean they are. Some propane generators are manufactured using substandard materials and manufacturing methods, thus making their quality questionable.

In order to get your money's worth when purchasing a propane generator, there are numerous factors that you need to consider. And even after all that, you're still left with having to move from shop to shop in search of a high-quality generator that fits your budget. Now, you don’t have to worry about engaging in all that hustle. We’ve got you!

What Makes Propane so Good?

In the presence of oxygen, propane burns at 1980 degrees celsius with a blue flame. The presence of a blue flame indicates that it burns entirely with minimal emissions. When it burns, it only produces heat, water, and carbon dioxide.

When used to power a generator, propane produces 25MG of energy per liter. Note that energy is measured in joules. 25 Mega Joules is equivalent to one million joules.

The energy produced by one liter of propane (25MJ) is converted to 6.9 kWh when it turns the turbines of the generator. 1 kWh is the energy required to run an appliance that consumes 1000 wats for one hour. That means that 1 liter of propane, producing 6.9kWh, can run a device consuming 1000 wats for 6.9 hours. Impressive, right?

How Does a Propane Generator Work?

A propane generator is a mechanical device that converts propane into electricity. It works by converting mechanical energy obtained from propane combustion into electrical energy.
A propane generator burns propane to produce heat, water, and carbon dioxide. The gases produced are used to turn the generator's turbines at high speed. This results in the generation of electric currents. The generator is fitted with power outlet cables, or a socket from which the power produced is tapped and utilized.

Benefits of Owning a Propane Generator

1. Propane has a limitless shelf life

Although an emergency back-up generator is a great safety net, you only need to use it on rare occasions. Sometimes, several months or even a whole year can pass without you ever using it. Fuels such as gasoline come with stabilizers, and after some time, they go bad and might cause damage to your generator.
Propane, on the other hand, does not have an expiry date. You can leave a propane generator sitting idle for months, and the fuel in it will still be in top-notch condition, no matter the weather.

2. Propane is more eco-friendly than gasoline.

If you are big on environmental conservation, then you will love propane. Propane burns in a cleaner way than most organic fuels. The reduced emissions it comes with are great for preserving our precious eco-system.

3. Lower operating cost

If you use your generator regularly, then you are bound to incur fuel and maintenance costs. Propane costs much less than gasoline and is available countrywide. Propane generators also require less maintenance. That, coupled with how long propane lasts, provides a very pocket-friendly option for any home or a business owner.

4. Propane generators can be used anywhere.

Propane generators vary in size. Smaller generators are suitable for regular-sized homes and small businesses. Also, if you have an entire building to run, you can find a large, high-voltage propane generator that runs as efficiently as a regular home generator, the only difference being the enormous power output.

Benefits of Propane Generators over Diesel or Gasoline Generators

1. Supply of propane is not disrupted in times of disasters or calamities

Diesel and gasoline are only sold at service stations. During severe natural disasters or catastrophes, these service stations are closed due to damage or to avoid a fire hazard. People whose generators run on these sources fall at a major disadvantage because they are unable to fuel their generators and are therefore left in the dark.

Propane, on the other hand, is stored in cylinders and is sold in many outlets. The availability of propane, coupled with the fact that it can safely be stored in bulk, makes it very suitable for use as an emergency fuel.

2. Unlike gasoline and diesel, propane does not deteriorate

Propane has an infinite shelf life. That means that you can store it in bulk for an indefinite time without worrying about it going bad. Also, propane does not get contaminated; hence it does not damage your generator with contaminants even when left idle for a long time.

3. Safe and easy to store

Gasoline is highly flammable and requires sophisticated storage mechanisms when stored in bulk. Propane, on the other hand, can be stored safely in bulk cylinders or safe tanks, with no risk of wastage during fill-ups or spillage. Propane tanks can be put in a variety of spaces hence making storage more convenient.

Propane Generators Buying Guide: Factors to Consider

1. Portable VS. whole house standby generator

Although they serve the same purpose, standby and portable generators have a few differences.
Portable generators are easy to transport. When not in use in your home, you can easily transfer it to your RV or another place. Standby generators, however, are much heavier and larger, making moving them very daunting,

Portable generators are usually older and produce less power than whole house standby generators. Also, whole-house portable generators come equipped with automatic switching mechanisms and are heavily insulated to protect them from damage. Portable generators, on the other hand, require to be turned on manually.

2. Power output

Before buying a generator, first, you have to estimate the power consumption requirements of your home. An 8KW generator would do well for most homes, but going for one that produces more than 10Kw is more advisable.

3. Fuel tank capacity, fuel consumption and runtime

If you are looking for a portable generator for a home, you should consider going for one with a tank capacity of not less than 7 gallons so that you get a suitable runtime. However, the runtime is not just affected by fuel capacity, the generators engine efficiency, and the amount of current being drawn from it also play a crucial role in determining its runtime.

In whole house generators, all you have to consider is how much propane it consumes per hour.

4. Portability

Generators are heavy. For that reason, moving them around is hard. Most generators come with a wheel kit to facilitate maneuverability, but not all. In some models, you have to buy the wheel kit separately. When purchasing a generator, it is best to go with one that comes with a wheel kit. However, wheel kits are pretty easy to install; hence even if you buy one without them, you can always fit them yourself.

Another factor to consider on portability is its weight. Generators that weigh less are generally easier to move. If you are planning on moving around with it a lot, it is best to go for one that does not weigh too much.

5. Propane cylinder holder

Most propane generators come with a tank holder. Propane generators that have a tank holder are generally safer and more convenient to use. However, the presence of a tank holder limits the size of the tank that you can use with it.

Most tank holders can carry 20-30 pound cylinders, which may be disadvantageous when you plan on using a bigger tank. However, you can always place your propane tank close to the generator and connect it using a gas hose. This gives you the ability to use a propane tank of any size.

Frequently Asked Questions (FAQs)

Question: are propane generators better than other generators?
Answer: The efficiency of propane generators is less than that of gas generators because they produce fewer BTUs. However, propane burns cleaner hence making it better for both the environment and your generator.

Question: How long does a propane generator run on a 20-pound tank?
Answer: A 20-pound cylinder of propane producing 441,600 BTU, will give you about 8.8 hours with an engine that consumes 50,000 BTU per hour.

Question: How noisy are propane generators?
Answer: To give you an idea of how much sound a propane generator produces when in use, consider a regular vacuum cleaner. A vacuum cleaner produces about 80dB. A large, powerful propane generator produces a sound that is almost equal to that. Smaller generators are quieter and can produce between 58 and 65dB.


In this time and age, pollution and fuel prices are high and will continue to rise as the years go by. That warrants the need for an efficient fuel that is not only cheaper but also cleaner.
