Empowers You to Save Hundreds on Electric Bills

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. The large LCD display counts consumption by the kilowatt-hour, the 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 will know if it is time for a new refrigerator or if that old air conditioner is still saving you money. Kill A Watt can help you reduce your power bill and will help find power-wasting appliances so you are able to decide whether it is worth keeping them plugged in. For standard 115 VAC appliances only, 15 amps maximum, 125 VAC maximum.

Find Out How Much Electricity You’re Using


Large LCD display counts consumption by the kilowatt-hour The U.S Department of Energy reports that 20% of our electric bills come from items that are left plugged in when they are not in use, or items that are in standby mode. With the Kill A Watt P4400 we can monitor the energy eaters in our homes and cut down our electric bills at the same time. Plug whatever item you want into the device and it will tell you the efficiency of that item by displaying the kilowatt per hour. This device will help you determine which items are costing you the most to run. The Kill A Watt also calculates voltage, line frequency, current, and power factor. You can calculate your electric bill before you even receive it from the electric company.

Test The Quality of Your Home’s Power

But measuring appliance consumption is just the tip of the iceberg. Because it can monitor voltage (Volt) and line frequency it can also test if an outlet is working, or evaluate the quality of the electrical power provided by your utility company. It can detect voltage drops around the house, help to predict brownout conditions or to make sure a new home’s outlets are in working condition before escrow closes.

    Fascinating gadget I absolutely love this thing.Having recently moved out on my own, and generally just enjoying statistics in general, I bought this to monitor my electric costs after two high electric bills in a row. The various results I found were quite surprising.My air purifier, which I bought here on Amazon, uses 85 watts all the time… 85 * 24 hrs * 30 days / 1000 watts = 61.2kWhr * $0.20 = $12.24 a month.Well, that’s quite a costly monthly addition I never thought of…

    Excellent Product! I absolutely love this product, it’s one of the best devices I’ve aquired in a long time. When I purchased it a few years ago, I paid close to $50, but it was worth every penny. Some of my joy from using the device simply comes from the fact that I’m curious how much energy the products in my home use (I now know, for instance, that my cable box uses 15W of energy whether it is on or off, at that it wastes a little more than 10 kilowatt hours each month, or that my fridge uses 350W when on,…

    How to reduce your power consumption Two years ago, my electricity consumption jumped about 40% and I ignored the problem until this fall’s rate increases. I wanted to find out what I bought back in 2003 that’s still eating power today. Enter the P4400 Kill-A-Watt unit, which is the only low-cost product of its type on the market today. I tried but failed to find its specifications online. So I bought a couple of these things to try them out. Here are the details on what it can do.* How big is the display: 4…
