Dead Simple Charging Station
Here's a dead simple cell phone charging station I installed next to our main entrance. It's just a pair of hangers of the sort you'd use in the garage to store a shovel or a rake. If your wall isn't made of barn-board like ours, you can screw the hangers into a block of wood and use regular drywall anchors to attach it.
Note: if you have an older phone with a transformer type wall wart you'll want to add a power strip with a switch since those older supplies drew nearly the same amount of power when disconnected from the phone as they did when charging it.
