Power Consumption Testing

Several years ago, I started wondering just how much electricity various home devices draw. This page contains the raw results of my measurements, using a P3 International Kill A Watt model P4400. All given values reflect the actual wattage at the wall, so they include any losses suffered by power supplies and the like.
