BASIC WATTAGE INFORMATION


  • Running Watts (Rated Watts) are continuous watts needed to keep your item running.
  • Starting Watts (Maximum Watts) refers to the maximum wattage the generator can produce. It usually takes 2 to 3 seconds to start motor-driven products such as a circular saw or a refrigerator. Motor-driven items require additional starting watts. Estimate 1 - 2 times the running rated maximum watts.
  • The average running watts to power basic items is 5000 - 7500 watts.
  • If your appliance or tool doesn’t have the running watts you can estimate by using the following: AMPS X VOLTS = WATTS
