 P4400 Kill A Watt Tool July 12, 2008
It is easy to use and provides various tests (volt, amp, watt, Hz, KWH); and is allowing me to check devices. Old refrigerator's power requirements, computer power drain, etc.
 monitoring electrical usage July 8, 2008
The Kill-o-watt is a handy little tool for figuring out what appliances are soaking up power and driving up our power bill. Well worth the cost and interesting just to see, for example, how much things like cable boxes and DVD players consume when passive.

our electric company has raised our rate a penny per kilo watt hour. This dose not sound like much but if my TV uses 200 kw an hour then it cost me $2 to watch 2 hours!
This Kill-A-Watt reader is great for showing me where my power hogs are in the house.
The only problem I have with it is that it was a little hard to understand. I wish that the instructions were easier to read and understand what the numbers mean.
This reader showed me that my energy saving light bulbs still rack up a lot of power! and so dose my laptop which I was always told used a LOT less power then a desk top.
Great tool June 30, 2008
Quick delivery. Great tool. Used daily to track energy usage by my Zenn Electric Vehicle. Displays Kilowatts used, current levels, and more. Also used to track usage by portable AC unit. Good to know how much electricity is being used.
handy gadget June 20, 2008

This handy little gadget lets you easily check the power consumption of any device plugged into it. It's easy to use. Buttons on the front select which value is displayed. It can track real time usage as well as cumulative usage. It also properly deals with VA vs Watts (which, if you're sizing a device for a UPS is a necessary distinction).... on some devices they're two different things.
When you first get it, you'll likely be tempted to go around checking every device you can find. (Will only do devices that use a standard wall outlet however, not big things like air conditioners, water heaters, etc that require a specialized outlet). It's actually pretty interesting to see what appliances actually use and how that varies with different appliance functions/settings. Many of them use power even when "off".
The main drawback of the design is that it blocks both plugs of a standard wall outlet, so you can't have another device plugged into the outlet at the same time. Sometimes it's an awkward fit. I'd highly recommend using a power strip or short heavy duty extension cord with it. (plug the cord or strip into the wall, the power monitor into the cord or strip and then the device you want to check into it.) This allows more flexibility and gets it where you can see it. A backlight on the display would be a nice addition as it's hard to read in dark corners.
overall, a worthwhile purchase.
