Introdução

Apple charging cables, such as the Lightning to USB Cable, are easily prone to fraying. Most commonly, this fraying occurs from device usage while charging. Cables may be subject to extreme angles while charging which causes the outer coating to loosen, tear, and ultimately expose its wiring. Exposed cable wiring is hazardous to both the device and its user, and may cause electrical shorting or even shocking. Repairing a frayed cable with heat shrink is an easy and inexpensive alternative that allows the user to safely charge their device.

    If the wire isn’t completely broken and if it is still working, you can also add some MSeal around it, this worked well for my adapters. Besides, I think it is a better idea to prevent cable breaks rather than fixing it afterwards. You can know more about here.

    One problem is the heat shrink wraparound bandage used isn’t equivalent to the original.

    Original lightning cables are wrapped with an insulator, a metallic shield and finally the outer white plastic jacket. And possibly a drain wire for grounding of the insulator.

    So the simple heat shrink plastic jacket applied totally lacks the electromagnetic interference shielding capability.

Thank you for taking the time to post your pictures and the steps to repair a lightening cord. I plan to do this repair, and also, apply heat shrink to the other end BEFORE that one frays. Thanks!!

I have cables that do not work anymore due to the fraying at the lightning port end. Are there instructions on how to fix this?

Christine Lucas - Responder

The wiring is too intricate, Christine. It’s not worth the time it would take, IMO.

Does this work with plastic straws instead of heat shrink?

joris van de noort - Responder

Plastic straws cause several issues: it will be difficult to push the Lightning connector through, they won’t shrink as easily or uniformly compared to shrink tubing, and they’re rigid so there will be a hard edge at the end, likely creating a strain point where the cable will fray. Heat shrink tubing is readily available at hardware stores and it’s not expensive.

My iPad charging cable has three layers frayed: the plastic jacket, the metal shielding sleeve and the plastic insulator sleeve exposing the cables underneath. How to fix them?
