charger sources
If you go to dealextreme.com, you will find many, many 12 volt chargers. If there aren't any with the tip you need, you can get the correct one at Radio Shack (or check dealextreme again). It's a simple case of cut, splice, and tape, or better yet get some shrink tubing. The prices on the site are so low, it doesn't pay to think about undertaking a voltage doubler circuit design.
By the way, if you were to try hooking a 5 volt source to the edge, you could end up discharging the edge and frying the charger.
