July 31, 2008 GOOD Magazine have you wondering how much power your HDTV consumes? Try the Kill A Watt.

Simply plug any electrical device into the Kill A Watt and the LCD display will tell you the drain of the device in Volts, Amps, Watts, Hz, VA or kilowatt-hours (kWh) - and calculate your electricity bill by the day, week, month or year based on your energy provider's price per kWh.

The Kill A Watt is available in three flavors:

  • The lesser original model, which is available at Amazon for under $20
  • The newer Kill A Watt EZ which retains your settings and calculates your electricity bills, available for $38 at Amazon
  • The Kill A Watt Power Strip - an eight-outlet power board with built-in Kill A Watt, $84 at Amazon
