The most annoying thing about the car charger for my cell phone is that the wire is just a little too short and the junction between the piece that fits into the phone and the rest of the wire always gets stressed at an acute angle. So it started working less and less well, and finally stopped charging altogether. I figured the wire must have broken inside the plastic piece. I am not normally a fixit type gal, but we had been given some Sugru and I thought I had an idea of how to use it to fix the charger.
Step 1: Cut open charger wire
Used a single-edge razor blade to cut the thing open and find the broken wires.
