U-Socket Vampire Power Draw

A company called FastMac has released a product called a "U-Socket" (link) which is a power outlet with two usb outlets on it for charging any devices that accept this method of charging (most new cellphones, tablets, etc.) One of the largest concerns with this method is that you can never unplug the usb power adapter, so there will always be some energy draw. I was concerned with the energy draw and wanted to compare it to my HTC EVO's standard USB adapter.

U-Socket Draw with nothing plugged in: .8ma (.8ma x 115V = .092Watts)
HTC USB adapater with nothing plugged in: 2ma (2ma x 115V = 0.23Watts)

In conclusion FastMac did a very nice job of keeping the Vampire draw to a minimum. You are looking at almost a year and a half before it uses 1 kwh, so this convenience is costing me less a penny per month in wasted electricity.

As for the installation I had no problem cramming it in to an old box that is original to my house, but your mileage may vary, the outlet is huge compared to a standard one. If you don't feel comfortable with the fact that electricity can kill hire some one to do it for you.
