Having a generator as a backup can benefit both houses and your businesses. Thus if you are willing to buy the best generator for your personal use, life expectancy should be the priority.

The life expectancy should be a decisive factor in buying a new one. Although the life expectancy of generators depends on how hard they are used and maintained.

Some brands have an expected lifetime of 20 to 30 years if they’re used 100 hours per year in an environment such as home use.

However, if used heavily and not maintained properly, they may last only five to ten years.

The good news is that the newer generators tend to be much better than older ones. They’re built with more durable materials and are of higher quality than earlier generations of machines.

You can get yourself a standard, medium-sized stationary fuel-powered generator for about 10 to 12 thousand dollars.

Thus you should take care of your need while buying generators. If you require more powered or lasting generators, for example, a generator that can last for more than above 40 years, then you have to pay a little more money than your expectation.

Thus, factors such as maintenance, how much you use, and how much capacity your generators are going to decide their lives.

How Long Does a Portable Generator Last?

If you want a generator, easy to place and move with a low life expectancy, then portable generators are for you.

Portable generators are not as capable as stationary generators, and hence they have less life expectancy. A portable generator can last from 1000 to 2000 hours per year if you use it wisely.

Though portable generators have less life expectancy than stationary ones, they can serve the purpose where you require low energy.

Another reason portable generators are famous and preferable for every house is that they are cheaper than stationary ones. The portable generator can cost you up to 200 dollars to 5000 dollars.

Thus, you can see a huge price difference between portable and stationary generators. Another advantage of a portable generator is that they need an installation process.

This means it is a money saver for you as you do not have to hire professionals to come and install them, unlike stationary generators. After buying the right portable generator, do not forget to take care of it.

You should not expose the generator to a lot of moisture as it has a negative impact on the life expectancy of generators. So it’s important to maintain them and store them properly after use.
