Step 1: What You'll Need:
2. A wall-wart 5V USB charger.
3. The appropriate cables for your equipment.
*Being 1.1 is not really necessary but, if you have one laying around why waste a 2.0?
Step 2: Now Assemble It
I've included a USB extension between the power supply and the hub just so that it doesn't all have to hang from the power outlet.
Your devices are not going to charge in record time because the limited output from the supply has to be shared around but, it certainly comes in handy just to keep a device from losing memory--like my Palm Pilot did :(
As the title says, this is a "Quick and Dirty" solution. If you want to tidy it up, there a plenty of related 'ibles for boxes, hiding cables and the like.
