Good Tool for Calculating Storage and Capacity.,

"The P3 International Kill A Watt Electricity Usage Monitor was a good tool for the purpose that I bought it for. I was able to measure the amount of power used by diffierent items and then calculate what size of inverter and what battery capacity would be necessary to run them for a week and for a month. Even though it does not store the information gathered, it worked quite well for the basic purposes for which I used it."

"I bought one of these about 6 months ago. There are 2 different models, the kill a watt and the kill a watt EZ. The advantage of the EZ is that you can enter your electricity cost and it will calculate your actual costs for you. The basic one just tells you the KW usage and you multiply that by your cost per KW to figure out your cost in dollars.
Basically you can plug what ever you want into it (within reason) and turn that device on. It will calculate the total power use by that device and then will estimate how much the cost would be over time (daily, monthly, yearly). For something that draws constant power (a light thats always on for instance) you can just plug it in and see how much it will use over the years. For something that is turned on and off (like a TV) it is best to leave it hooked up for a few days so it can figure out how often it is left on.
Because of this I have started turning my computer off at night, unplugged unneeded devices, etc. I have also seen how little some things cost that I thought was expensive (my TV only costs about $20/year with my current usage).
My only complaint is that you can't unplug it from the wall and look at the results from your testing. if they had a battery in there that would be nice because often I can't read the display from where the outlet is, so I have to use an exention cord just to get the Kill A Watt to a location that I can read it. Other than that it would be rated Excellent."
