    I love this thing
    Once on my recently. own moves, and generally just statistics enjoy in general, I bought this on my electricity costs after two high electric bills in a row monitored. Different results I found were quite surprising.
    My air purifier, which I bought here on Amazon, uses 85 watts all the time … 85 * 24 * 30 days / 1000 watts = 61.2kWhr * $ 0.20 = $ 12.24 per month.
    Well, that’s a pretty expensive monthly addition I never thought of. And that’s just the beginning.
    My Vornado fan uses 45w … my air conditioner, 6 (of 12) points up to 1200 watts. Jeez.
    My Computer
    idle with external drives, uses about 250w. This extremely intensive things, like a video, 310W.

    My light behind my computer desk, with five 10-watt bulbs , not really use 50-watts of total power. No. It uses out 50-watt bulbs, 30-watt to work PLUS apparently only for the light unit.
    Also you will find out all those things you never knew , and possibly save money by letting out, or replace power-hungry
    The product is made in China just like everything else now

    This review ( What is it )

    I love this product, it is one of the best devices I have purchased in a long time. When I bought it a few years ago, I paid around $ 50, but it was worth every penny. Some of my joy with the device simply comes from the fact that I’m curious how much energy (the products in my home, I now know, for example, that my cable box uses 15W of energy, whether it is on or off, indicates that it’s a little more than 10 kilowatt-hours wasted every month, or that my fridge uses 350W when on, or that my laptop only uses 40W – knowing a useful fact when I buy an inverter to use it in my car, was), but it can also be used to save energy I (thought that may suggest the switch on the rise supressors of my computers at night to save me almost $ 5 be) per month from my electric bill. Moreover, it is interesting to know where all the energy you use is, and also what members of the family the most electricity (you could do a side by side comparason a child’s computer with you) to use.

    Even if my Kill-A-Watt had been around for years, I still take it regularly to test any new device in my house. I know that my phone charger uses 4 W, my regular battery charger 5 W, and my IC3 15 minutes battery charger 73 W.
    Certainly most not so much fun with this unit as I do, but it can be both practical and comfortable for people like me, or those that save some money from their electricity bill. It is also perfect for any off-grid, generating its power is. Using solar energy or other renewable resources

    This review is from: P3 International P4400 Kill A Watt Power Usage Monitor (Tools & Home Improvement)

    Two years ago, jumped up, my power consumption by 40 % and I ignored the problem until this fall, the rate increases. I wanted to see what I bought at that time in 2003, which still have the power to eat today. Enter the P4400 Kill-A-Watt unit that the Low-only Cost-product of its kind on the market. I tried, but did not find their data online. So I bought a few of these things to try them out .. Here are the details of what it can do
    * How big is the display. 4 digits
    * What are the front-panel key functions are:. volts, amps, watts, volt-amps, power, frequency (Hz), KWH, timer ( since reset) * Continental
    it loses its data when the power fails: Yes

    * You must plug the device into an unswitched outlet, it can not measure overhead lighting or large appliances
    * It is the time (hours reported. min to 99: 59, then hours for about a year) since the last reset but will not say how much of that time the connected device is turned on to find out how I
    . ? use I have an Excel spreadsheet with the following columns: device in estimated wattage hours / month, kilowatts avg / month, measured kwh / day, measured kilowatts, annual cost I walked through the house and inventoried everything I could find. ., entry in a row of the table Then I filled in the estimates:
    – hours / month: if I use a TV 3 hours a day, I give the formula 3 * 365/12, if I have a treadmill 45 minutes . to 10 days a month, the formula is 0.45 * 10 * 365/12
    – kilowatt (average per month): formula watts * hours / (24 * 365/12) / 1000 When 60 a. have-watt light on 24/7 left, you should set the value 0.060, if you have it on a 12-hour timer, you should see the value 0.030
    – an annual cost. formula kilowatts * 365 * 24 * costs. Locally, the cost 13.5 cents so 100-watt device works at $ 118.26 per year.
    OK if I chart I then plug the Kill-A-Watt, the elements that have to measure maybe chew more power than my estimates. For a device that you leave on all the time and used a steady wattage, you can simply measure it for a moment and enter the kwh / day figure in your spreadsheet fast. for appliances like refrigerators or computer monitors or TV sets, you will want to have the unit plugged in anywhere from a day to a week before entering your kwh / day figure.
    The first what jumped at me was how much it costs to run this eco-box desktops Sure enough, the culprit turned out to the hot AMD and Intel processors. the tech industry wants you and to gigahertz . other performance figures concentrate, they will never tell you how many watts the computer will draw – because nobody does not even ask Consumer Reports A modern desktop easily draws 100 watts: refer to my earlier figure to see how much it costs a, to go tied the dollar amount to the future laptops would save power (though not necessarily enough for the purchase price) save off the PC when they would not in use money, but at the expense of productivity.. if your time you do not appreciate waiting like 2 minutes every time you check an email (add those 2 minutes to over a year)
    Bottom line: the Kill-A-Watt device is on your attention some of the equipment can cost you unnecessary money must be concentrated, and will definitely change the questions you ask when you purchase future household devices. I want to see a feature-laden version, but not if the kill-A Watt cost much more than the $ 25 I paid makes
