5500 Watt Generators – Why and Which?

A well-built, reliable generator is absolutely never a bad thing to know that you have. What’s meant by this exactly? Even if you don’t need a good generator at one particular point, there’s every chance that you will shortly after. Having a reliable generator that’s ready to cater to a number of situations is a great thing to have.

Different situations will, obviously, require a different amount of power. For this very reason, a lot of people that are looking at purchasing a new generator look to go for one with the most power that they can find. This isn’t, however, the best idea. Large and powerful generators tend to output power that is not suitable to be used with all types of electronics – they often aren’t fitted with inverters.

Another downside of large and very powerful generators is portability. A generator that’s able to put out 10 or 12 thousand watts is fantastic, once you get it to where you want it to be that is! Moving around a large and powerful generator can become an extremely exhausting task for anyone.
