The first step toward conservation is knowing where energy is being wasted.
Placed between any appliance and its outlet, the Kill-a-Watt measures electrical use by the kilowatt-hour and displays it on a large LCD screen. Then you can calculate consumption patterns by the day, week, month, or year.
The Kill-a-Watt gives you insight into your electric appliances' efficiency so you can decide if any of them needs replacing. It even lets you check the quality of your power by monitoring voltage, line frequency, and power factor.
The Kill-a-Watt Electricity Usage Monitor is an elegantly simple, smart, and essential tool for every home. Includes informative conservation tips.
