Essential Info

The cost of electricity can really hit you where it hurts-your wallet. Now with Kill A Watt you can reduce your energy costs by identifying the real energy abusers. Simply plug your appliance into Kill A Watt and assess how efficient it really is. The jumbo LCD display measures consumption by the kilowatt-hour, just like your local utility company, so you can quickly calculate costs. It's perfect for seeing how much juice that freezer in the garage is sucking up, or to see how much it costs to keep your computer on throughout the day. Measuring appliance consumption is just the tip of the iceberg. By plugging this in, you can also test if an outlet is working, or evaluate the quality of the electrical power provided by your utility company. It does this by monitoring voltage and line frequency. It's perfect for detecting voltage drops around the house, to predict brownout conditions or to make sure a new home's outlets are in working condition before escrow closes.

Imagine being able to forecast your electric bill before you get it. With the Kill a Watt, you can calculate electrical expenses by the hour, day, week, month, even year. With accuracy within 0.2%, you can safely know what to expect your expenses to be.

    I really like my kill-a-watt meter. I have been playing with it for days. I tell many people about it. I do like your company and your products but could you please remove me from any email distribution lists. When I want/need something from you, I have your web address. Thank you very much.

    RICK -- palm desert, CA   1/11/2013
    I am still evaluating
    SHERIDAN -- fullerton, CA   12/21/2012
    The only fault I have with the Kill A Watt is there is no built in light. It is hard to read if the outlet is under a desk or other dark place. Using a flashlight tends to simply reflect back off the screen.
    ROBERT -- surrey, BC   12/16/2012
    Good product, good company with which to deal.
    THOMAS -- shelby township, MI   12/9/2012

    quality, performance and delivery were excellent.
    Bob -- chiang mai, Thailand   11/30/2012
    I need a Kill A Watt which operates on 220-240V system. Can you recommend? Do I need to specify more details other than 220-240V? Thank you!
