Connect your appliances into the Kill A Watt, and assess how efficient they are. A large LCD display counts consumption by the Kilowatt-hour just like utility companies. You can figure out your electrical expenses by the hour, day, week, month, even an entire year. Monitor the quality of your power by displaying Voltage, Line Frequency, and Power Factor

Perfect when you are curious.:
Does a great job, I did not checked the accuracy with another multimeter but I suppose this one is accurate. I was able to check each device consumption in my house and see how much power is used on a long run... If you are curious like me, that's the perfect tools.
Useful Too - Idea for upgrade though:
Very good tool for assessing appliance energy utilization. You can see current usage real-time. For freezers which cycle on and off, you can measure consumption over a day or week or any length of time. I'd like to see either an illuminated readout or the ability to unplug and have the readings remain visable. It is tough to see usage when in a dark place.
Valuable tool for energy calculations...:
Works very well and provided all necessary information for analysis of power quality and quantity. Highly recommend.
I did not know that used 20 watts when it is off.:
There is a CD player in our basement that my wife uses sometimes. This told me that even when it is "off" it uses 20watts. A power strip solves the problem, but unit allowed me to conduct an inventory of my house looking to deploy these. Use it with a three/two prong adaptor and a short extension cord, so you can test hard to see plugs and insert it in two prong extension cords. Unlike the ammeter which clamps around a cord, you have to turn things off and unplug things to test them. Also this does not... more info
