Product Description

Electricity bills are rising. Now you can cut down on costs and find out what appliances are actually worth keeping plugged in. Simply connect these appliances to the Kill A Watt, and it will assess how efficient they really are. Large LCD display will count consumption by the Kilowatt-hour, same as your local utility. You can calculate your electrical expenses by the day, week, month, even an entire year. Also check the quality of your power by monitoring Voltage, Line Frequency, and Power Factor. Now you´ll know if it is time for a new refrigerator or if that old air conditioner is still saving you money.

A very useful gadget to have around. I needed one to measure the actual power consumption for a gaming system I am building but this gadget can be used on anything that consumes power. As per the label on the product (model # P4400):

Operating voltage - 115VAC
Max voltage - 125VAC
Max current - 15A
Max power - 1875VA

I would recommend that you get a power extension cord. As the back of this product plugs into a power supply, it will either block up other outlets on your power bar/wall jack or you will have a tough time reading the display. I got a 6ft power extension cord (with ground i.e. 3 pin) and that way I can plug the power extension cord into the wall outlet and plug this product into the other end of the power extension cord. I can then plug in my device (for example, a PSU or a computer monitor) into this device. That way, I don't need to try and reach into the back of my workstation to try to read the display from from obscure angle.

Incredibly useful. Use the watt setting to see how much electricity is being drawn in real time, or use the kWh setting to see the cumulative amount, which you can use to calculate an average wattage, or figure out how much running a device will cost you in the long term. Just look at your electrical bill to find out how much you pay per kWh. It's a simple, well designed, and high quality product. Highly recommended.

Couldn't get any better, great functionality (no need for a manual), excellent display.
Amazon Canada shipped and delivered within one day.
Great product. I plug it in, take the reading and that's basically it.
Surprised to see my computer accessories consuming around 6.5W while not in use, I power everything off now using a
power bar with red illuminated switch.
Also considered the RioRand Plug Power Meter (the one with more rows of display) but now 100% happy with the 'Kill a Watt Monitor', not missing anything.
Great product, recommended!

Useful and helpful in tracking active and phantom electric usage around the house.

I am somewhat obsessed in tracking down and finding unwanted and phantom electric usage around the house. With the rising cost of energy, I am working on justify moving to a more renewable energy source, but first I need to understand how I use energy. That way, I can determine grid-tie or off-grid approach is better. Or simply, to supplement during power outages.

This device is basic, but does exactly what you need. The only drawback is that you need to keep it plugged in to check all the measurements as it has no “off power” memory like its bigger (more expensive) brother. The EZ model. But, I did not see a need for the increase cost, and as I understand, you still need to plug that one back in in order to retrieve the data anyway.

Usage is simply, though some tips.
1) Plug the device you want to measure into the Kill-A-Watt monitor first, then into the outlet. The monitor will start recording as soon as it is plugged in. You may only be talking a couple of seconds, but sometimes I find it just made things easier to do in the end.
2) The plug fit on the monitor is a little “snug”. Part of the reason I plug the appliance into the monitor first. That way I am not fussing when reaching into those hard to reach areas.
3) If you are just wanting the standard Watt/kWh usage (like say for your router/modem, coffee machine or TV when in power on state). Do wait until the appliance has completed its power-up before taking a reading. However, remember that in order to get a true kWh reading, you are best to let it monitor for a full 24 hours.

I think this is a tremendous value. So many of us are uncertain how much power some of our appliances are using, even when they are "off" (such as devices with remote controls, which must maintain power to the receiver in case the remote is used to turn the device "on").

My only disappointment was that all the collected info disappears when you unplug the monitor - there's no "memory" feature, and it's sometimes difficult to see the readout if the unit is plugged in behind an appliance or in a floor outlet (just put a small extension cord between it and the outlet). But for $25, this is still a great buy, a great conversation piece, and something your friends and neighbours will all clamor to borrow (if you ever finish testing all your appliances!)

Great tool for showing power usage but I wish only for two things that would vastly improve it's usefulness: A backlight or illuminated didgits so I could see under my desk without a flashlight and it hogs both receptacles which to fix this would require a physical redesign.
Well it does what it's supposed to but could be much better.
