Ever wondered how much power your TV or amplifier uses? Wonder how much it costs you per hour, day, week or even month? Use the Electricity Usage Calculator to find out the voltage, wattage or amperage of the device in question and then use the calculator to find out how much it will cost you based on the wattage!!!
