I got this form Home Depot website and then plugged it into a few devices from computer to Coffey maker it is easy to use. But has political themes built into it that lean left On the global worming climate change belief By its language of Co2 and carbon footprint which by definition is political language
But aside from that I like how it will test home devices and get basic knowledge. How to cut the power bill by hunting down vampire devices. my Coffey maker it it was left on and plugged in for a year. Cost 843 dollars round number so. This has a motion sensor and custom settings to respond to motion thus saving money ......

With this device you can figure out how much power a device uses. It will also tell you how much it costs and how much CO2 is generated in a day, a month or a year.
It is nice that the part that the device plugs into has a long cord connecting it to the display unit. This means you don’t have to crawl down on the floor if the outlet is low down.
This seems like a good way to figure out how much power you are using. You can also see how much power devices are using when they are not even turned on. Another added feature is that it has motion detection and can automatically turn devices off when no one is around.

Rated 4.0 out of 5.0 by MichaelD Too Many Unneeded Features
The Kill A Watt Edge is a great tool to let you know how much power anything in your home is using helping you same money. This particular model has a lot of features including a motion on and off that takes some reading and work to disable. As the instruction leave a little bit to be desired I wish it would be in the off position by default. The unit it self is rated for 15 amps (a typical power outlet circuit in your home) and 1,100 Watts. All in all a good product but with too many unneeded features. That's why I only gave it four stars.

Rated 5.0 out of 5.0 by SGMillerDesigns Great power meter
This Kill-A-Watt unit is a great homeowner power monitoring tool. It has the ability to give homeowners knowledge about what appliances are actually doing.
One of the biggest issues with modern appliances is that many appliances have a power switch that do not actually turn the unit off, but puts the unit into a stand-by mode that still consumes power. This tool can monitor every aspect of an appliance's power consumption, and can track it's power consumption over a length of time.
The meter separates into two segments, connected by a small cable. One unit plugs into power stream, between the wall socket and appliance. This way it is much easier to view the display and toggle unit functions.
The unit does feature the ability to actually completely disconnect appliances from power with a switch, so it can keep those power consuming "stand-by" electronics from eating away power. The power switch can be controlled by a little motion detector, but seeing as how I have dogs, I was not able to actually test the functionality of this part of the tool.

Rated 5.0 out of 5.0 by mixmox good gadget!
This is a well designed and made item. The engineering seems to be solid too.
This has a number of uses:
1) it can be used to measure the electricity being consumed in real-time. i.e. Amperage, Wattage, and the Voltage (and kwH).
2) The electricity consumption can be expressed in terms of cost or CO2 consumption and also expressed in terms of daily, weekly, monthly or annual savings.
3) The device will switch power off when the items plugged into it are in standby mode. (i.e. they are not in actual use) when nobody is nearby. The standby consumption is determined when first plugged in, so it will not work with devices that come out of standby mode when initially getting power.
4) The device can be used as a pure kill switch that is governed by motion detection. i.e. if no motion is detected for some period (e.g. 30 minutes) it will switch off the power. Power is switched on again if motion is detected.
5) There is also a manual on/off switch that allows the power to be switched, with a LED indicator.
The product has two physical parts that allows the display half of it to be unclipped from the part that plugs into the power socket. This makes reading the screen and working its controls very much easier and practical. It is well designed and executed.
Switching is done in a spike free manner (at the zero voltage moment in the AC cycle). Nice touch.
The instructions seem to be a printout of a PDF printed two pages on a sheet of paper and back to back, so you have to leaf through the sheets of paper rather than paging through a booklet. Just pay close attention to the printed page numbers and reassemble into a logical order.
I am extremely energy conscious and having a handy real-time meter for mains current will be very useful.
Materials and workmanship have a 6 months warranty from date of purchase.

Rated 4.0 out of 5.0 by DEstefan Works well, but complicated
This device measures the power usage of anything you plug into its outlet. It can also show how much the power usage costs you, as well as how big of carbon footprint you leave.
The device can be separated into two units, connected by a wire, so that you don't need to crawl down to your outlet to see the display, which is a huge plus over other power consumption meters.
It also comes with a motion detector which switches the plugged in devices on and off automatically. I'm not sure for what you would use this function, but it's there. BUT, if you want to measure the power consumption e.g. of your freezer you HAVE to switch off the motion detector or the meter will switch off your freezer.
The meter comes with 16 pages of instructions, but I would need another 20 or so explaining what they are trying to say in the first 16. How to switch off the motion detector is never really explained, press and hold the meter-button for 3-4 seconds, then set the motion detection range (PIR) to 0 ft / off.
Over ll nt bad device, but much more complicated than was needed.

Rated 4.0 out of 5.0 by Camano Very accurate and flexible power saver
This KillAWatt Edge Model P3-P4490 serves two purposes. The first is to monitor and record power usage, cost, and CO2 emissions of an appliance. For power, it can report volts, watts, amps, kWh, and elapsed time. CO2 and Cost can be reported on a daily, monthly, yearly, or total basis.
The second purpose to serve as a motion-activated "standby killer" to eliminate vampire power draw when the attached electronics are not in use. If the power measurement indicates the system is in standby and there's nobody around for the specified time, then the power is cut off completely. Power is restored when motion is detected again.
I've used the original Kill A Watt for several years to monitor the power usage of various appliances. It has a couple of drawbacks that have been addressed in this new model.
The first improvement is the addition of memory so the values aren't lost if the unit is unplugged or the power fails. The second improvement is the ability to separate the meter assembly from the power plug by up to 4.5'. When outlets are 18" off the floor, reading the fixed display on the original Kill A Watt was a challenge, requiring bending over or sitting on the floor. There's a cord storage compartment in the back of the meter assembly. The display shows two values - the current power measurement and either cost or CO2. There are also status indications showing the current mode of operation.
The provided instruction sheet is very dense and hard to read. I downloaded the PDF manual from the manufacturer's website so I could zoom in on the pages. I also found the on/off switch for the connected appliance to be very sensitive - just brushing against it would activate it.
When initially installed it is in standby killer mode. There are a number of configuration options accessed by pressing and holding one or more of the buttons for 3 seconds. The display shows new labels for buttons when in setup mode. You can change the CO2 units between lbs and kg, the CO2 rate per kWh, the cost per kWh. You can set motion sensing to always on, off anytime there is no motion, or off when there is no motion and the unit is in standby. The motion-off time can be set between 10 seconds and 2 hours. There are also settings for motion detector distance and standby power draw threshold. The cumulative values are stored until the unit is reset by the user.
Since the KillAWatt Edge itself is in standby when waiting for motion, I wondered what its standby power draw was. I used my older Kill A Watt and it displayed zero! The old unit isn't that accurate measuring low power draw, but I'm sure the Edge will have less power draw then whatever it's controlling, especially if you plug the TV, cable box, AV receiver, and DVD player into a power strip that's plugged into the Edge.

Rated 4.0 out of 5.0 by ToolTimeTony Measure consumption - control energy use
This is a very handy device to measure the energy consumption and cost to run of almost anything that plus into a 110 volt outlet. I got it because I wanted to measure the total load on some circuits that were loaded with holiday lights. The meter is very simple to operate to measure consumption. Just plug it in, plug in what you want to measure into it, and hit the meter button. You can toggle among volts, watts, amp, and Kilowatt hour. You can also select to measure CO and Cost for day, month, year, and total. I also used it to measure a number of small appliances, TVs, etc. to understand just how many I could run at one time with both my smaller 2000 watt and larger 5200 watt generator. The unit is also able to cut power to vampire power users by programing it by holding the meter key and then selecting a number of functions that cut power based on lack of movement or selected delay. Vampire appliances use power even then they are switched off, usually TVs, cable boxes, and anything that has a “standby” mode. It uses motion and passive infrared sensors to detect motion and turn off the outlet when no one is present – if you program that mode of operation. The unit handles up to 15 amp and will kill the outlet and indicated an overload if you exceed 15 amps. It takes some reading to understand how to access and utilize all the features of this unit, but it is very simple to measure consumption. The meter section can be separated from the outlet by about four feet of tether wire, so you can read the meter without having to bend down to the outlet level – a very nice feature. This is a very useful unit to gain an understanding of what it cost to run your devices.
