The charging cord on my Mini is just starting to kink near where it plugs into it, and I want to reinforce the cord before the wires inside break. Can anybody think of a reinforcement readily available, hopefully something in most households, or barring that, something from a small-town store? Im thinking some sort of tubing like the outside of an electric wire connector duct-taped on (not easy if even possible) but it would have to also fit over the wider part where it plugs in, or be wrapped of course. I don't think a piece of a drinking straw sliced lengthwise and wrapped would be sufficient strength to hold the kink straight, but that's the idea. Thanks for any ideas!
