Power Tools & Contractors Appliances: Wattage Requirements

Are you a contractor looking for a new generator? Then you need to know how much power you will need to fulfill your job. That is why we have decided to create this list of rough estimates of wattage consumption of the most frequently used power tools.

Just keep in mind that these are estimates and you need to check your tools to learn the precise numbers of running as well as starting watts. Our data is gathered from reputable government websites, most popular generator manufacturers like Honda, Generac or Yamaha and merchants like Lowe’sSears or Home Depot.
