    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

    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.

    1.0 out of 5 stars I am disappointed.
    By S. Locke on June 4, 2018
    I bought this in Oct 2017 and really have not used it much. Today I tried to measure the watt usage on a small AC unit. The ground pin on the 4400 came off. A call to tech support didn't help. They said it was out of warranty. I opened the unit up and cannot tell if the ground pin is screwed in or soldered. Not very strong in any event. I am disappointed. It should be noted that the ground pin is not connected to the circuit involved in the measurement. It actually just sits there. That said, it's a little unnerving to have your meter "fall apart". The ground pin should be substantial since it helps stabilize the meter while in use. Still disappointed. It may still work but that does not make my review any higher.
    Update: After further examination, it appears that the ground was press fitted into the little circuit board. Not good at all. There wasn't much holding it onto the circuit board. It was going to fail for sure.

    2.0 out of 5 stars Melted.
    By James on July 5, 2017
    I used it on my computer and it nearly melted. Computer was drawing 11 amps max and this device is rated to 15. Don't trust this with high currents for long amounts of time.

    Mide en tiempo real tu consumo. Te sorprenderás con algunos electrónicos que consumen aún apagados, así como cosas que consumen mucho y otras que no. Perfecto para el cálculo y/o control de tu consumo.
    Al conectarlo te indica la salida de corriente, conectad algún aparato y te indica su consumo, e incluso sabrás los kwh desde que lo dejes conectado hasta que se desconecte.
    Con los botones sabrás el voltaje, watts/vA, Hz, amperes y kw/h
