What Is A Propane Generator?

Propane generators run on liquid propane gas (LPG) instead of regular gasoline. Propane is known to be environmentally clean, costs fewer bucks, and readily available. 

On top of that, it has a prolonged shelf life, meaning that you can store the gas for extended periods.

The propane gas is extremely flammable. When using it, you need to be careful to prevent the gas from leaking. 

The major difference between a propane generator from the regular ones emanates from the slight modifications of the carburetor. The fuel tank is always attached to the generator via a hose.

Propane generators consume 3.44 gallons per hour.

Why You Need a Portable Propane Generator

Primarily, portable generators are versatile since you can get power almost anywhere. 

Secondly, they are cheap to maintain. The generators require almost zero maintenance. The price of propane is half as much as what you pay for gas.

Thirdly, these generators are some of the quietest options on the market, thanks to their quiet engines.

Fourthly, propane comes in tanks that make it hard to spill or leak. This cannot be said of gas.

The other highlight of portable propane generators is the fact that they have a dual-fuel function. This is a very important addition to these devices, especially when a propane crisis hits. You can always resort to gasoline.

Finally, yet importantly, propane generators produce clean energy. In fact, there is no other type of generator that beats the propane generator when it comes to producing cleaner and safer electricity.

Best Portable Propane Generator Buying Guide


A portable propane generator should be easy to use. The features must be easy to understand and explore.

The starter is very important in this context. When you get a recoil starting system, make sure that you are comfortable with using it.

The best starters are electric. With them, all you need to do is simply push a button and your unit is good to operate.

The control panel should be well designed. It should be intuitive and not give you problems operating it.


All the models we’ve featured are some of the most portable options on the market currently. They are easy to carry around.

Additionally, they come with ergonomic handles and easy-rolling wheels to make moving around with them easier. In campsites or job sites, you will find moving these units pretty easy.

Portability is great but you have to compromise on the maximum power output of a propane generator. Heavier models are powerful but difficult to carry around.

Power Output

How much power a given generator produces should be a key consideration. It all comes down to one thing - your needs.

The more your needs, the more power you will need from your propane generator. With that said, power supplied is measured in watts.

If the wattage is higher, then the generator is more powerful. The opposite is true. The models represented in this guide range from 1200 - 12000 watts.

The power output also helps you to be aware of the generator size that you need. Remember the more power you want, the more money you will need to splurge to meet the rising prices.

Fuel Tank and Runtime

The larger the propane tank, the longer it takes the generator to run. With larger tanks, you do not have to keep refueling every other short time. Most tanks will give you a runtime of between 5-9 hours, although this can go up to 20 or more hours.

The secret to an extended runtime is keeping your usage of power as low as possible. This gives you maximum hours.

Quiet Operation

Most of the generators featured here are quiet. You want to carry a quiet generator with you in the neighborhood.

In general, propane generators do not emit tons of noise, thanks to their low-profile engines. It gets even better if the unit has an inverter.

Check for models with low noise output. It is good to read the decibel specifications.


The other important factor to keep close tabs on is the budget. If you know what your needs are, you will definitely know the type of generator you want.

The key thing is to consider the quality before allocating a given amount to it. For example, carefully consider if the features are what you are looking for. Until then, you do not want to go into a frenzy buying.

You may just dump your bucks in a useless unit. This is a long-term investment - so consider its durability, power surge protection, or power output among many other key aspects.

Always ensure you remain within your budget.

Final Words

With the above list of the best propane generators, you should have a good starting point when in the market for one. The models were carefully researched before we recommended them.

Find out what ticks your box from top to bottom. If you do not see anything better than what you want, be sure to check the guide to inform your decisions.
