I am fed up of laptop power supplies developing a break in the cable because the insulation and housing is so thin and flimsy that the conductor keeps bending a lot in the same place. Cleverly, or so I imagined, I took to preemptively wrapping the end of the cable in electrical tape, down to a little ways from the plug, in such a way as to arrest its curvature.

However, what defeats my cunning plan is that the bending seems to make the tape slide. After a while, the taped part of the cable develops a high-curvature region which, while fixed easily by the application of more tape, makes me wonder how many rolls of tape it takes, and how absurd the resulting charging cable will look, if I repeatedly adopt this solution over a fair few years of the computer's life.

I'm missing a better solution, aren't I?
