Note: Typical wattage varies by make, model, and age — check your appliance's nameplate for its exact rating.

A plug-in power meter gives you the real wattage for any specific appliance, rather than a typical estimate.
Appliances with compressors or heating elements (fridges, A/C, dryers) cycle on and off — "hours used" should reflect actual running time, not just time plugged in.
Standby/phantom power from electronics left plugged in adds up — check our Whole-Home Energy Load Calculator for the bigger picture.
