Wattage Calculator

Easily estimate your power needs with our Wattage Calculator. Select how you’ll use your generator and the devices you plan to power, and our tool will calculate the total wattage required. This will help you choose the right generator to keep everything running smoothly.

Step 1

How will you use your generator?

Whole Home/Backup Use

Power home essentials like appliances, air conditioners and more during a blackout.

Recreational Use

Power necessities for outdoor activities like camping and tailgating.

Job Site Use

Power tools and accessories at the jobsite.

Business & Events

Find reliable power for any event, anywhere.

Step 2

What items will you be powering at the same time?
