From the Manufacturer
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.

Customer Reviews

Great little device. Footprint needs updating
Purchased this to get an idea of device loads.. and particularly vampire loads. It helped me identify which were the worst offenders, and with some devices, interestingly, there was zero draw when off. This was the case with my 7+ yo TV. It's definitely a handy gadget.

The one issue I have with it is the footprint. It's sized just big enough that it covers at least one open plug when you plug the unit in. If they fixed that it'd be a 5-star.

Kill A Watt Is More Than Advertised
I bought this to determine Kw usage around the home and it really does work. I also used it to teach my 7 year old about current, voltage, and watts.
Well worth the money.

So useful... I love this gadget.
I don't know how I didn't have one of these before now. It works great, the display is clear (but you may need a light to read it under a desk, or behind furniture). I've used it to see how much power my PC was using to choose an appropriate power supply, and how much money I'm spending running that old refrigerator. (By the way, my mid/high-end PC only uses about 300W so no need to waste money on a crazy 600W+ supply, and a new energy efficient fridge would pay for itself in a few years).

Well worth the money spent on it. I highly recommend it to others.
