P3 International P4400 Kill A Watt Electricity Usage Monitor
Electric bills can be murder. But now you can cut down on costs and find out which machines are actually worth keeping plugged in. Simply connect your appliances to the Kill-a-Watt electricity usage monitor and it will assess how efficient they really are. The unit's large LCD display counts consumption by the kilowatt-hour, the same as your local utility. You can calculate your electrical expenses by the day, week, month, or year while also checking the quality of your power by monitoring voltage, line frequency, and power factor. Now you'll know if it's time for a new refrigerator or if that old air conditioner is saving you money. Don't be another casualty. With the amazing Kill-a-Watt, you'll have wasteful devices pushing up daisies. Price: $23.43
