Power generators are small, self-contained power plants built around a reciprocating engine and an alternator. The engine and the alternator are usually combined into a single enclosure, which can be as big as a tractor trailer, or as small as a suitcase, depending on how much electricity is needed.

House generators give you peace of mind by keeping your home's power running through a blackout. Some homeowners are taking things into their own hands and purchasing home generators to give them peace of mind.

Home generators can be used as a backup power source or simply to reduce reliance on the power grid. A home backup generator protects your home automatically. It runs on natural gas or liquid propane (LP) fuel, and sits outside just like a central air conditioning unit.

Portable generators are often used on job sites to power air compressors, nail guns, saws, hammer drills and other equipment. They're also great as an emergency backup system for larger appliances.
