Product Description
Watts Up Pro, which instantaneously displays the wattage being used, as well as the cost, in actual dollars and cents! Watts Up? provides tons of information (see list below), yet it is simple to use. Only six values are displayed in the main modes. Additional information is available in the detail mode. Clear English wording on the LCD is used to describe what is displayed. Watts Up Pro measures the voltage and current thousands of times a second so it has an incredibly fast response time, enabling you to "see the surge" of power when appliances are first turned on. The peak value display captures this surge so it is displayed even if it happens too fast to see live. The minimum voltage display shows the line quality and voltage dips. Minimum current and minimum watts can be used to monitor variances in appliances that run continuously. Watts Up Pro also measures true RMS power (including power factor) which is what utilities charge for. Watts Up PRO has additional analysis tools, like the Payback Calculator, which automatically calculates the time required for a new energy-efficient appliance to pay for itself. Monthly savings are highlighted, and compared to the purchase price of the new appliance. It includes all the displays of Watts Up. In addition, the PRO records all the data into non-volatile memory, which can be retrieved even if power is lost. One thousand data points are stored, starting with a sampling rate resolution of one second. The sample rate resolution increases over time (sample rate equals total time divided by 1000) so years of usage can be accurately recorded. The included serial cable and software program allows the data to be quickly downloaded to a PC where the included software creates a data table and easily manipulated graphs. The data can also be exported in a comma-delimited format to popular spreadsheet programs for further analysis.

Exactly what I wanted December 3, 2007

This is a terrific tool. It works great. It collects a huge amount of info, that is easy to download to your computer. There are analysis tools in their software package (the meter itself does a lot of calculations on it's own, you don't have to download the data to get a lot of meaningful numbers) but the software works on one set of data at a time (that I've found). To do multiple items, I'm going to need to write a spreadsheet that will analyze the data while combining different items, or time periods, but I'm sure it will pay off.
Already found some surprising things: Coffee Maker with timer, uses almost a watt when NOT in use. That's around 10-15 cents a month to sit there. I know it's not much but why waste? I'm unplugging it now. When brewing and keeping warm, it uses 878 Watts. That's about $11-20 a month at 3 hours per day. I think I might look into getting a thermos to keep the coffee warm after brewing. It should reduce the cost to about $1-3 a month to brew 1 pot a day (maybe less - I can't remember exactly how much time it takes to finish brewing a pot). Then I'll keep it hot in the thermos. The thermos will pay for itself in 2 or 3 months. I should be able to get some more years use out of the Coffee Maker also.
Computer with way too many bells and whistles, is much more efficient than I thought. $5 to 8 dollars a month if I run it almost 24 hours a day.
The transformer chargers for cell phones, pda, etc. which so many people insist use lots of energy when plugged in and not in use, don't. My pda DC Converter, uses about 1 cent a month when not charging. Voltage is so low it doesn't register. I'll pay a penny to avoid having to unplug and plug that in constantly. When charging it consumes between 2/100ths to 5/100ths of an amp.
Same with the cell phone charger. When plugged in but not charging. It doesn't consume enough wattage to register and the monthly cost of leaving it plugged in is 1 cent. Maximum consumption while charging is 1/10th of an amp.
I've also noticed, that many items have a spike in power draw when first turned on or plugged in. I wouldn't be surprised if I found that the converters use more power by continuously spiking when plugged in repeatedly. I'll have to run an experiment.
Empty battery chargers are worse though, but I already unplug those when not in use. My four slot AA/AAA charger uses about 4 cents per month when not in use. While charging 3 AA's it consumes about 70 cents a month but that is if I used it constantly. I only use it about 4 or 5 hours a month.
Oh, and my old Tivo that I mindlessly left plugged in when I bought a new Tivo was consuming $1.50 - 2.50 a month.
Still need to run 24 hour tests on this stuff to get the best averages, but it's been interesting finding out what individual products really use.
Saved me 70% off my refrigerator electricity bill February 23, 2006

My electricity bill at my house was over a $100.00 a month. I couldn't figure it out until I bought this machine. Apparantly, my 25 year old refrigerator was working well, but was sucking up over $50.00 a month on electrity. After I used this machine, I bought a brand new refrigerator that only uses $15.00 a month. This is a must have unit.

While this is not the product of the century or one that will make the top ten list in many peoples minds, this is indeed a great product if you need to know what your current draw and power consumption is on a given appliance. It should be noted that this unit should not be used on high amperage load units such as a refrigerator or an air conditioner, it does have a great function for the miriad of smaller units such as your computer current usage, the display consumption such as a plasma and yes even a LCD since they are getting so large that consumption is up on these as high if not higher than plasmas with the newer power saving electronics.
This is a great item to evaluate reducing your "carbon footprint" and finding what products achieve that end. It is also an incredible unit to document the power reduction in properly setting/calibrating TVs/Flat Panels/projectors and such. Studies have shown that properly calibrated displays can have a 20,30, and even 40 percent reduction in energy usage, and this unit can help document the changes.
The Watts Up Pro requires a computer or notebook to run the software that is available from the company to chart, graph, and spreadsheet the measured parameters. If you are serious about tracking and analyzing your power consumption, then this reasonably priced unit will help you achieve it.
Great to see what you are paying your electric bill for. May 16, 2009

Easy to set up if you have a recent electricity bill on hand. Able to compute average monthly costs based on your current rate. Our electricity rates change for the summer so I will have to remember to change it.
I tested it on my laptop power supply for fun and could see when the battery was charging and how often. (Total power requirement negligible.)
Now to test my 11 year old air conditioner.

All the power data you could ever want, including top notch data logging. I'm working on making some fancy power usage graphs for all of my appliances. For example, my laptop power use in different modes (screen full bright while burning MP3's, dim at idle, and in standby).
