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

The instrument arrived well packaged in perfect condition. Exactly what I expected. I am very pleased with the features. Simply to use. The small one page "manual" that came with it is very clear. Is very important to use it with the "Power Strip Liberator" (a short cord extension) in some crowded places where could be difficult to read the screen on the instrument.

Works as advertised, highly recommended
»
With rising energy costs, I wanted to know where my Kilowatt Hours were going to, this product has helped immensely. If it plugs into a wall, it can be plugged into this unit. I would leave it attached to various appliance for a few days each to see how much energy each device was consuming.
Highly recommended!

Good product, do the expected work.
»
This product works as expected. I purchased this unit to make an analisis about parasit power consumption in my electronic appliances in home.
I discover the following:
- the lcd requires 180 ~ 230 watts. After going to standby or shutdown, the tv use 60 watts for 3 minutes. This is to cool down the lcd lamp for protection (fans and additional circuit works for this time). Can be a mistake if I remove the AC cable power or enterely shutdown the tv without allow this process to finish. Good discover. After this 3 minutes, the standby mode on the monitor only requires 05. to 1w.
- my motorola cable system requires the same ammount of power (27 ~ 30 watts) no matter if this unit is ON or off!!!!... all the time is fully powered (because have an internal hard drive). But I believe (wrong!) this unit must save about 50% if is off.. but no!!!!
- the blackberry / sony ericson chargers do not drain any power (0W) from AC if the phone itself is not connected. I DON't need to disconect this chargers from the outlets.
- My APC Smart UPS 1500 drain 30 WATTS! even when is completely turned off!!!Is better to disconnect this unit from the ac cable!!! amazing!...
- My pc (dimension 9150) is a power hungry pc. Because have pentium D (first edition) who requires a lot of power. This pc requires 230 watts but when I play Command Conquer (3D real time strategy) and because I have a HD2900 ATI High Definition card who requires 650 watts PSU. Interesting: when I play the game the power rise from 230 to 300~320 watts!!!!
This unit is very usefull to understand how the electronic systems works and if are energy efficient and how you must manage this units to save power and money.
Highly recommended, is cheap and you can check your ac freq and exact voltage (i have 128 volts from 127 expected in the ac line)......
enjoy and sorry my english

Great device.
»
This is the best way I know to find out how much power your electrical devices are using. Found out that battery chargers don't all work the same. Some stop using power when they are through charging and some don't. Those are the ones to unplug when not in use. My computer monitor uses approx 20 watts less power when in standby mode. Coffee brewers and toaster ovens use lots of power. Coffee cup warmers use a considerable amount too. This device will pay for itself with the electricity you will save by knowing what devices to use and which ones to unplug when not in use.

A great, easy to use device to help cut your electric bill
»
I bought one of these a year ago when our electric bills were sky high and I couldn't figure out why. The device is easy to use, you just plug it in an outlet and then plug the appliance or device that you want to measure into the Kill A Watt monitor. You can tell at once how many watts per hour it uses or you can leave it plugged in over several days or a week to see how much electricity the item uses over the time period and then get an average per hour.
I found that one of those little electric heaters was costing us nearly $100 per month to use on a constant basis. I found the incandescent light bulbs were using 8 or 9 times the electricity that a compact fluorescent would use. Regular lights on a Christmas tree were using almost 10 times what the same number of LED bulbs used. I ran around the house plugging in one thing after another, the TV, electric blankets, computers, stereo and appliances. I also ended up making a lot of changes and saving money on our electric bill. Changing out light bulbs alone saved us almost $30 per month.
This little device more than paid for itself. Two thumbs up for this one!
