Looking at the Pros and Cons of Gas Generators

If you have a gas-powered generator, you won’t be as inconvenienced the next time the power goes out. This kind of system can be very useful, but since there are many options for generators, it’s important that you do your research before investing in one. This overview will go over some advantages and disadvantages of gas generators.


Gas generators are different from standby generators, which are permanently installed and typically connected to a natural gas or liquid propane line. Since they’re smaller, gas generators can be much more affordable. If you only need a generator occasionally, this kind of unit could be a smart choice from a financial standpoint. Many options cost well under $1,000. In contrast, standby generators could cost thousands of dollars before taking into account installation costs.


Another benefit of gas generators is that they’re portable. They have handles and wheels, allowing you to move them easily. They might weigh around 40 or 50 pounds, so many people should be able to wheel them to a convenient location when necessary. When no longer needed, they can be stored in a safe place.

Convenient Fuel Source

You’ll never run out of a way to power a gas generator. With regular gasoline always in supply, you’ll have convenient access to a fuel source.

However, you’ll have to make sure you have fresh gas ready for your generator, keeping in mind that gas can deteriorate with time. You can plan ahead, or you may need to run out to the gas station in the event of a power outage. This might not always be feasible, so it can certainly be considered a limitation of this type of system.

Limited Power

Also note that gas generators tend to be less powerful than standby generators. With a maximum output of 10,000 or 15,000 watts, for example, a gas generator would let you operate your refrigerator and potentially a few other appliances and lights. It would probably not provide enough power for you to run a heater/furnace or an air conditioner.

Safety Concerns

If you have a gas generator, you may be the one setting it up during a power outage. You’ll have to remember to place it outside, away from doors and windows, to prevent carbon monoxide poisoning. In contrast, a standby generator would be professionally installed in a safe location, ready to automatically start whenever necessary.
