I made this page because I was curious about how much power is used by various devices and chargers. Original post here. All devices here measured with a P3 International "Kill A Watt". Feel free to add your own measurements, please note if you use a different device. Power is measured in Watts. Apparent Power is measured in volt-amperes.
