If you are in the market for a new generator you will want to know exactly what you are getting before you spend your hard earned money. When rating portable generators that you are thinking about buying, there are several factors that you will want to keep in mind.
First off, you will want to buy a unit that will be able to provide you with the power that you need. If you are going to be using your generator as a primary source of power you will be looking at one group; but if you are using your generator as a backup source you will be looking at another. This is a great way of narrowing down your choices right off the bat.
While rating portable generators also take into consideration the reliability of the unit. You will want to make sure that you buy a generator that will last you a long time so that you get the most for your money.
Also, find a unit that is quiet. This may not seem that important, but for in home use you will definitely want to take into consideration how much sound a generator will emit. This will help you avoid having to live with a loud generator until you have the money for a replacement.
Overall, portable generator ratings are done differently by every person. The most important thing to remember is that you will be using the generator, so you will want to get a unit that suits your needs; not those of somebody else.
