The Kill A Watt can help you reduce energy costs and identify the real energy abusers around your house, office, or other space. Simply plug an appliance into the Kill A Watt and it will assess how efficient it really is. The large LCD displays the power consumption by the killowatt-hour, just like your utility company does. You can figure out your electrical expense for that item by the day, week, month or year. Also, evaluate the quality of the electrical power provided from your utility company by monitoring voltage, line frequency (Hz), and power factor (VA)--perfect for detecting voltage drops and brownout conditions before they damage delicate equipment.
