If you’re curious how much electricity your television set uses even when it’s turned off, or whether your refrigerator should be replaced by a more efficient model, then the Kill A Watt EZ™ electrical usage monitor from P3 International may be just the thing. Simply plug it into any 110 volt wall outlet, key in the price you pay per kilowatt-hour, and plug the appliance (maximum 15 amps) into it. It not only displays how much the device costs to run, but the voltage, amps, and watts it uses as well.
Available from CableOrganizer.com for $49.95.
