Are you in search of a backup generator for your home? Before you buy one, it’s important to understand the power requirements of the electrical appliances and tools you need to keep running during a power outage.
I have great news for you! Our team here at Generatorist has helped over 600,000 people find the information they need about generators and we’re here to help you too.
These tables & charts will help you determine the size and power of the generator you’ll need as a backup source of power. Be sure to check the actual wattage consumption of each appliance and power tool in your home separately.
Our information is sourced from reputable government websites and popular generator manufacturers such as Honda, Generac, and Yamaha, as well as merchants like Lowe’s, Sears, and Home Depot. We add new appliances and update the numbers on a regular basis to make this the most comprehensive resource out there.
