How much electricity does your computer use if you leave it on overnight? How much power does your TV use when on stand-by? A new energy efficient appliance may be able to pay for itself in lower electricity costs, but how will you know?

Simply plug the Kill A Watt into a wall outlet and then connect your appliances to the monitor to find out how efficient or wasteful they really are.

On the screen you will be able to monitor the kilowatt hour consumption of an item to learn how much it costs to run. You can determine your electrical expenses by day, week, or month. You may cycle through displays including voltage (volt), amperage (amp), wattage (watt), line frequency (Hz), and power factor (VA).
