Discover how many watts different household appliances use so you don’t overload your power sources or invest in the wrong generator.

One thing to note first is that while we do get our estimation from reputable sources like government websites, Honda, and Home Depot, the actual power consumption of your appliance brands and sizes can still vary.

The rough estimations in the charts below can be a helpful starting point but ideally, you would check the power consumption of your specific appliances.

Additionally, when choosing something like a generator, you want to keep peak watts, running watts, and THD levels in mind too.
