Most of us have a half dozen or more gadgets that charge via USB. Wouldn't be great if we could stop fussing with "wall wart" power adapters and just plug our devices into a wall outlet? Now we can, and usually without the help of an eletrician.
In this review from TechHive, the SnapPower Outlet cover with USB Charger is featured. Each outlet cover is a reasonable $20 and required no wiring. It has prongs that rest against the live power terminals inside the wall outlet. That connection supplies power to the integrated USB charger.
I have a dozen or so SnapPower outlet covers with integrated LED nightlights that work the same way. Although sometimes you need to wiggle the outlet cover as you put it onto the outlet for the power connection to be made, I can confirm that this type of connection worked on every outlet I tried.
The SnapPower USB Charger Outlet Cover would be a great gift for anyone with USB devices to charge, including you.
