Giving your cell phone or iPod a semi-permanent, clever-looking home on your wall doesn't have to cost more than $2. A used shampoo bottle and some basic tools are all that's needed for MAKE's outlet-mounted "charging pocket."
If this specimen looks familiar, that's because it is—we previously pointed to a similar charge station for single gadgets, but that tutorial's been taken down by the author "due to safety issues." That might raise a few eyebrows, but DIY haven MAKE tends to see this project as fairly safe, at least for cell phone chargers with built-in transformers. Your mileage will vary, though, with how firm your sockets hold a plug, and you shouldn't hang anything too heavy in the charger that might pull a plug loose. That said, commenters have suggested using a faceplate screw to better secure the pocket holder and reduce the tension on the plug, and pulling out the plug if you're going for long periods between charges, as most any power "brick" draws phantom power, even when not in direct use.
The design is a bit different than our previous example (and its commercially purchased cousin), as the case hangs from holes drilled for the charger's prongs instead of loosely hanging on top of them. As for cost and convenience, you can pick out any cheap shampoo with a nice look to its plastic bottle, or, if you're already set up with one, pull out the razor and drill and get to work. The tutorial includes a handy printable drill guide for making neat prong holes.
