If you haven't heard yet, there's a cool useful little device that you can buy for about $20, called the Kill-A-Watt. You plug it into the power outlet, then plug something into it and observe various fun facts about the plugged in device, such as the power consumption, voltage, amperage, etc. I started plugging things in and recording power consumption that you can see below. Here are the results I got so far (updated often):
- Vizio P50 HDTV 50" plasma
- standby: 0-1W
- on – perfect white screen: 450W (OUCH!)
- on – bright screen: 350-430W
