What a great way to research energy cost and drain your typical household appliances use. I tested mine on lights and power tools and really think this could be something to try throughout the house to see where my energy bill is going to and what simple things I could do to save electricity. Easy design and straight-forward operation. fairly quick reading during operation.

If you've ever wondered how much electricity an electrical appliance/tool/computer/light was actually using, this thing is the bomb. Just plug the appliance into the unit and it'll tell you the power consumption. I'm not sure you'd want to plug a high-draw tool like a skill-saw into it as that may be more than it's designed to handle, but go ahead and post your results.

Honestly, I never knew how curious I could become about how my appliances use electricity until I gave this a try... One of the things I had been wondering around my home was with recent additions of two different aquariums, and noticing that each had around 4 or 5 things plugged into it, I was really concerned with the level of electricity they would use. This tool gives you several different ways to track and monitor usage and it is dead simple to use!!

Rated 4.0 out of 5.0 by Sld3313 Helpful Tool to Determine Usage
I was so excited to try this monitor on my refrigerator to see electricity usage. The monitor displays many different items, volt, amp, watt, Hz & KWH. This is a good tool to use to see what items in our home use the most KWH. The only downside is this cannot be used with an electrical extension cord. What refrigerator plugs into a socket you can see? You have to view the readings while the monitor is plugged in. That makes it almost impossible to use for a refrigerator without pulling out the refrigerator and taking readings while the monitor is plugged in. There is no memory, so when unplugged, you lose the readings. This is a good idea, but really only useful on items where you can get your face to the plug to read the output.

Electricity can become really expensive.
I have a hunch what appliance eat up the electricity but there is no proof.
This small unit can now tell you what the usage is.
This will certainly tell the fact about electrical use.
In my opinion, every one should have this.
Just read all the instruction before you use it.
As a real man, i skimmed the instruction and it cost me much time.
Its simple operation will give you the fact of which appliance is the actual energy hog.

The display is on the front of the unit, is approximately 1" X 2" and easy to read. It would be a lot better if it had a back light. Also it would have been nice if the display was on the top. Most of the appliances I wanted to use this on sat in front of the outlet and couldn't easily be moved to read the display. If the display had been on top I could have read it. It measures and displays volts, amps, watts, volt/amps, line frequency, power factor, kilowatt hours and elapsed time. The kilowatt hours feature can be used to determine what each of your appliances cost to operate.

Rated 5.0 out of 5.0 by Mikey95 Nice solid prosumer quality instrument
Nice product for checking power consumption of household appliances, i.e. refrigerators, coffee makers, toasters and electronic devices i.e. receivers, televisions, chargers for batteries. I have no way to assess the accuracy of the monitor, but all of the line characteristics (frequency, voltage, phase angle) seem reasonable. The display is not backlit so it can be difficult to read in low ambient light, there is no cord so you either need to plug the monitor into an accessible outlet or use it with an extension cord. It is capable of measuring instantaneous power consumption (watts) as well as cummulative power consumed (kilowatt hours). Because of the arrangement of the plug and the display, the unit will block the second receptacle of a duplex receptacle half the time. Simple to use, but interpreting the results requires knowledge of electrical concepts. No batteries required.

First of all this device covers the entire receptacle, so if you really need to use both receptacles, plug a 12" 3 prong extension cord (Amazon) into the wall, plug the kill a watt into the cord, then the appliance to be tested into the kill a watt. This unit is approx. 5 1/8" h x 1 5/8"w x 2 3/8" d. Yes it will hang down but since it is not back-lite when you check it you can manipulate it to read it. It will display 8 units of measure but only has 5 buttons on the front and no clear cut directions on how to use the buttons, however they are marked with the different designations volt-amp-watt etc.. Although this has many functions one has to think the main reason is to find " cost of operation " of a particular appliance. That is my intent, because when I ask why did/do you leave "X' on all the time, I always get, "It doesn't use that much electricity". Really! Now I have the device to prove the kilowatt hours and cost to run a appliance/device. It will not only prove a point, pay for it' self and probably save you money in the long run.
