 Knowledge is power July 16, 2009

I just started using the EM100. I opted for the EM100 over the Killawatt model. It was a few bucks more seemed to have more available information on the display simultaneous. You can enter in your average cost per KW-Hour and it can show you a cumulative dollar amount.
I recently built 2 new semi-high end PCs and was curious as to their actual power usage. A 1.4 KVA UPS, 2 x quad core PCs , network kit and other typical PC accessories. All running with 100% cpu load is about 475 watts. Now I know this. I don't need to guess. The A/C in the same office uses only 50/80 watts with fan only (low/high) . Power usage goes up additional 400 watts when the compressor is engaged.
I have a few dim-able ballast florescent lamps as well. I found that they use as low as 13 watts on the lowest , and 55w at the max. What was interesting is that if I set the dimmer down to where there is 95% ( eye ball calibrated ) light output compared to max, uses only 30 watts.
This product is a neat little gadget to have. It is very simple to use. It provides real time and peak power usage of any device ( or power strip ) that you plug in through it. Next I will see about my fridge and TV/stereo. I am curious how much juice things really do use when they are in standby/off.
Get one. Its simple and does what it says it does.
Fun device! October 28, 2009

Offers really neat electricy use measurements. Very fun to use! Buttons are a little cheap feeling, but still work well.
cheap but works July 26, 2009

The product is not high quality but it works. Although, I question the accuracy of it sometimes. However, it is good enough to get the work done (find those appliances hogs.)
good stuff January 23, 2010

Don't know how accurate it is and it is in desperate need of an on/off switch to save the batteries but seems to work good. The batteries are button cells and can get expensive if you don't shop around.

Very cheap feeling buttons, but it gets the job done. I haven't used the advanced features at all, just plug it in and see the current watts then come back and look at the kilowatt-hours used and elapsed time.
