What Size Portable Generator do I Need?

With the holiday season upon us, more and more homeowners are installing outdoor lights in their yards to get ready for the holidays. One of the most popular outdoor lighting fixtures is the string of clear, white, or multicolored lights that are hung on the roof of a home. These lights are generally powered by an electrical outlet on the house, but when the outdoor power outlet is not in reach, a portable generator is a great alternative.

A portable generator is a great option for homeowners who want to string lights on their roof, but don’t have an outlet close to the roof. When shopping for a portable generator, the first thing to look for is the amps and the watts. The amp rating is the amount of power the generator can provide continuity and the watts is the amount of power the generator can provide at a given time.


Typically, a 4 amp generator can power up to 1,500 watts of lighting. If a homeowner wants to string a string of lights on the house, they will need a generator with enough power to provide at least 6,000 watts of electricity.

A portable generator is a device that allows you to convert the energy of gasoline into electricity. They are typically used in situations where there is no access to power. Generators come in many sizes, with the common sizes being about 6500 to 7500 watts. The difference in sizing a portable generator and power output will depend on choosing a generator size. For example, a typical 6500-watt generator will be able to power a refrigerator, a microwave, a TV, and most lights. On the other hand, a 7500-watt generator will be able to power all of the above plus a sump pump and a space heater.
