What Is a Propane Generator?

Propane generators run on liquid propane gas (LPG) instead of gasoline. Propane is known to be environmentally clean, costs fewer bucks, and is readily available. On top of that, it has a prolonged shelf life, meaning you can store the gas for extended periods.

The significant difference between a propane generator from the regular one comes from the slight modifications of the carburetor. The fuel tank is permanently attached to the generator via a hose, and typical 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 propane price 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 about gasoline.

The other highlight of portable propane generators is their dual-fuel function. This is essential to these devices, especially when a propane crisis hits. You can always resort to gasoline. Finally, yet importantly, propane generators produce clean energy. No other type of generator beats it when it comes to producing clean and safe electricity.

Our Selection Process

We considered the following key factors when buying the propane generators to test before recommending them:

  • Portability: Most of our picks come with ergonomic handles and easy-rolling wheels to make moving around with them more manageable. You will find moving these units pretty useful in campsites or job sites.

  • User-friendly: Some of our selections also have electric starters. With them, you only need to push a button, and your unit will fire up to generate electricity.

  • Power output: Our top picks have the highest wattage because the higher the wattage, the more useful the propane generator is. The wattage ranges from 1200-12000, which will help you find the generator size you need.

  • Noise emission level: The options we chose offer super-quiet operation and clean, reliable power, thanks to their low-profile engines. It gets even better if the unit has an inverter.

Best Portable Propane Generator Buying Guide

Image Source:

1. User-Friendliness

A portable propane generator should be easy to use and it has features that are easy to explore and understand. The starter is essential in this context. When you get a recoil starting system, ensure you are comfortable using it.

The best starters are electric. With them, all you need to do is push a button, and your unit is suitable to operate. The control panel should be well-designed. It should be intuitive and not give you problems operating it.

2. Portability

All the models we've featured are currently some of the most portable options on the market. They are easy to carry around. Additionally, they come with ergonomic handles and easy-rolling wheels to make moving around with them more manageable. You will find moving these units pretty easy in campsites or job sites.

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

3. Power Output

How much power a given generator produces should be a key consideration. It all comes down to one thing - your needs. More energy requirements mean finding a powerful propane generator. With that said, the 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 be aware of the generator size you need. Remember, the more power you want, the more money you will need to splurge to meet the rising prices.

4. Fuel Tank and Runtime

The larger the propane tank, the longer the generator lasts. With larger tanks, you do not have to refuel after every short time. Most tanks will give you 5-9 hours of runtime, although this can go up to 20 or more hours.

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

5. Quiet Operation

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

Propane generators generally do not emit much 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.

6. Budget

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

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

You may dump your bucks in a useless unit. This is a long-term investment - so consider its durability, power surge protection, or power output, among other vital aspects. Always ensure you remain within your budget.

Frequently Asked Questions (FAQs)

Image Source:

1. Are propane generators any good?

Propane generators are good since propane is known to be a clean burning fuel and environmentally friendly. They produce less carbon monoxide, releasing half the amount compared to a gasoline generator.

Additionally, propane has a long shelf life because it does not degrade over time, unlike other fuel sources like gasoline and diesel. You just need a high-quality tank for storage to ensure you are well-equipped with enough fuel.

2. What is the disadvantage of propane generators?

Propane generators are less efficient than other generators operating on other fuel sources like gasoline or diesel. Similarly, propane will burn through much quicker, so you need bigger propane tanks to keep your generator running during a power outage.

Another disadvantage is that these generators have engines with a shorter life expectancy that require frequent maintenance than other alternatives. For example, you are likely to replace a propane generator much sooner compared to other alternatives.

3. How long will a portable generator last on propane?

Most portable propane generators have a capacity of 1000 gallons, and with a burning rate of 2 to 3 gallons per hour, a 1000-gallon propane tank can run a generator for up to 400 hours. However, the actual run time will depend on the wattage needs of the generator. For example, 7KW power output will run 66 hours on a 100-gallon tank while on full load.

4. What is the best small propane generator?

The best propane generator is Westinghouse WGen3600DF Generator for its excellent performance. This propane generator has easy-to-operate features, beginning with a simple push electric start button.

Another distinctive feature that makes it the best is its fuel gauge and auto-low oil shutdown for optimal performance. It also has dual-fuel technology operating on propane(3240 Rated Watts & 4650 Peak Watts) and gasoline (3600 Rated Watts & 4650 Peak Watts).

5. Is propane more dangerous to run than gasoline?

Propane generators are safer than gasoline generators since gasoline is highly combustible and easily degrades. Also, propane is more environmentally friendly because of the lower carbon monoxide production.

Final Words on the Best Portable Propane Generators
