Types of Generators
There are three main types of 4000 Watt Generator; these are; Medium Speed Generators; these units are more likely to be found in commercial applications such as forklift trucks, but can produce power on a larger scale. It is an exact power output and speed is determined by the internal components, speed is measured in RPM. Small, medium & large Speed Generators; this type of generator produces much less power than a large, medium speed or a small, medium speed unit, as the name suggests they are very small and not suited for commercial applications.

How to use a generator
Generators are used to provide electricity to your home in the event of a power outage. The amount of the electricity supplied by each unit varies based on the size of the load. If you have an RV, boat or other large equipment that needs to stay connected to the power, it will require a lot more power to do so.
The higher the horsepower and the smaller the load, the more efficient the generator is. However, if you have a large family, or a large number of small appliances or a motorized vehicle, you may be better off with a less powerful and more efficient unit. Generators are rated by power at the watts (W) rating on the label. They are divided into different sizes based on the amount of available power.
Four to eight hours of continuous use is often recommended for these compact workhorses to keep one room or one light switch on all the time. If your life requires a continuous flow of electricity, then you should avoid purchasing a low-horsepower unit. You may be overpaying for the convenience and longevity of the big guy.
