I've seen a lot of these frayed cables, so I've started to fix them before they break with heat shrink tube. I get my heat shrink on Amazon, like this handy and inexpensive pack. I prefer the heat shrink tubes without internal glue - it has higher flexibility and a smaller outside diameter once shrunk.
Heat Shrink Tubing on an Old, Frayed Lightning Cable |
In the photo here, you'll see that I slid on a 1.25 inch length of heat shrink over the lighting connector, and then shrunk it into place. I chose a diameter that just barely fits over the lightning connector. In all, it took about 60 seconds to perform this repair.
Warning: the white plastic of the lightning cable has a pretty low melting point. It seems to start to melt at about 125°C (or about 250°F), which is the same temperature that the tubing shrinks. Therefore, strive to minimize the heat and time used to shrink the tubing.
Now the cord has a lot more strength at the point that sees the most stress, and you can't even begin to tell that the underlying cord was falling apart. That doesn't mean that the repaired cord will last forever, but my bet is that its life will extended many times over.
And there you have it. Now go save the life of some Lightning Cables.
One Final Tip
Another problem I see often is that some people are cleaning their cables with "product". Some of these products decay the rubber shroud of the cable. Stick to a water-dampened rag.
