This really works well. I was trying to determine the start up wattage of a freezer so I could decide what generator to use. Worked as described.

Rated 5.0 out of 5.0 by Chris Great for measuring PC power usage from the wall...
I bought this to be able to measure PC hardware power usage and it does that very well.

Rated 5.0 out of 5.0 by SteveVA Very handy for your budget and generator
I enjoy using this device around the house since I have received it. The manual is easy to follow and I quickly set my rate to 11 cents per kWh, which is what I pay. Once the device is plugged in, you get a reading quickly. It averages out as the device (like a fridge) runs then stops. You can easily scroll through the hourly, daily, monthly and yearly costs. If I charged my phone continuously for a year, it would cost $6.57 as seen in the photo.
Other readings include Hz, watts and amps. All are important if you use a generator. I have a 2000 watt generator and can tell what my appliances, such as my fridge, draw so I know what I can plug in. Hz is important as well for sensitive electronics such as phones and laptops. My outlets and inverter generator read around 60 hz, where it should be.
I plan to get a lot of use out of this device and recommend it if you are curious about cost, especially and extra fridge or TV. One downside is that the device is a little big so it won't fit well on a power strip.

Rated 5.0 out of 5.0 by blrow3 Great way to kill those energy vampires in your home!
The kill-a-watt Es power monitor is super easy to use and understand. It gives you real time data on the power consumption of whatever device you plug into it. This unit had helped me identify several electronic devices and appliances that I thought were in a low-power or off mode, but we're wasting a ton of electricity! This u it paid for itself in the first month! Great addition to my toolbox!

Rated 5.0 out of 5.0 by RVPower works great
Contrary to what others have said, I find the Kill A Watt EZ meter to be reliable. I am running my entire motorhome through it--1500 watt heater, microwave, hair dryer, lights, battery charger, etc. Of course, not everything at once, but I have run a high wattage heater through it for about 2 months without smoking the unit. You just have to pay attention to its 15 amp limit. It records the kilowatts I have used and gives me a readout of the total cost, so I can pay my neighbor for the power I am borrowing.

Rated 5.0 out of 5.0 by Rolly A must have to observe power used by various loads!
A very useful instrument used to measure the power consumed by different 115 volt loads. This instrument was used by me to show that my beer fridge was consuming about five times the the power that it should have been using. I now have a new beer fridge! This meter works extremely well.

This $30 product saves me more than $30 month. Once you start analyzing your utility costs, you can decide if you want to spend an extra $11 a month to leave the Tv on 24 hours a day or install a timer. My Bunn coffee maker cost $4.50 per month, so I added a timer, $2 month now. Added a timer to our back porch heater to save $30-$60 month in the winter. We unplugged and removed several items also.
We can work to save some money or work to make money. We do lots of things manually now after using this meter and Michael Bluejay's how to save electricity web site.
Great science project. More fun than a barrel of monkeys!

Rated 5.0 out of 5.0 by SJWM2015 Well worth the money
It's been very interesting to find out what's using electricity in the house. My new computer speakers that are supposed to "auto shutoff" and use little electricity was not the case (and it was left monitoring for plenty of time). I purchased a switched power strip to turn it off. Old computer pulls 1.9 watts while the new one uses none when it's off. These are just a couple of examples. This is easy to setup and use. Wish I would have purchased this years ago.
