Not sure what kind of portable generator you need?
Not sure what wattage requirements you have?

Check off the items on the left that you need your generator to power, and find out what type of portable generator is right for you.

*Be sure to check your tool, appliance, or other electronic device for exact wattage requirements. The above are only estimates.

Most electrical products with a motor are classified as reactive loads. Such loads often require as much as 3 times their "run" rate to get the motor up to speed.

You may also use our wattage worksheet to calculate your estimated wattage requirements:
