How to repair a frayed Apple AC Adapter Wire

소개

Over time, the wire coating of an Apple MagSafe Power Adapter may deteriorate leaving the wires exposed and possibly subject to electrical shorts. By covering the exposed wires with heat shrink you can protect the power adapter and yourself while continuing to use it to charge your computer.

    • Measure the approximate length of heat shrink needed to throughly cover all nearby damage with a single piece of heat shrink.

    • The length of the heat shrink should be longer than the actual length of the damaged or exposed wire.

    • Use 3/8"(10mm) diameter heat shrink. This size diameter is large enough to slide over the charging interface and small enough to secure itself on the wire when heated.

    • Cut the heat shrink to the appropriate length using scissors.

    • Use a heat gun or a lighter to apply heat to the heat shrink.

    • Continue until the heat shrink has shrunk and is tightly attached to the wire.

    • When heating, always keep the heat gun moving around the heat shrink. Do not apply heat to one location for too long. Overheating the heat shrink may cause further damage to the wire or wire coating underneath and may melt the heat shrink itself.

    • Optional: Apply multiple layers of heat shrink if you think the wire will be used in more demanding situations and want to ensure its protection and longevity.

    • The 3/8"(10mm) Heat Shrink Tube has a minimum diameter after shrinking (0.19"/5mm) that is larger than the Mac Charger Wire's Diameter. So, to create a proper hold, we need to increase its diameter. Wrap it in an electric tape or something like the red wire covering shown in the picture, to increase its diameter before shrinking it.

    • There is also 4:1 Shrink Ratio Tubing where you might not need to do this, but 2:1 Shrink Ratio Tubing is typically easier to get if you don’t want to order online.

    • Once the heat shrink has shrunk and cooled down, flex the wire in different directions to ensure the heat shrink is properly attached to the wire.

Thanks! Wish I had seen this repair technique a long time ago... would have saved a lot of money on buying new power supplies and an expensive laptop repair when a cracked cable shorted out. Much appreciated!

This method fried my cable and it stopped working… Do not recommend anyone to try it. Now I have to buy a new one…

Minimum sensitivity required. I think you missed the part where it reads…

“When heating, always keep the heat gun moving around the heat shrink. Do not apply heat to one location for too long. Overheating the heat shrink may cause further damage to the wire or wire coating underneath, and may melt the heat shrink itself.”

I know this is from 2017, but I had a big laugh when I read John Myr’s post. Who in their right mind would even attempt to make a repair if you don’t know how to use a heat gun or even a cig lighter? Further don’t try a repair if you don’t understand how to shrink shrink tube! LOL LOL I would have paid money to see this guy burn through his cord! OMG, thanks for the big laugh!
