    • Identify that the cord being repaired still works, then make sure both ends are unplugged and free to be worked on.

    • This method is best for when the insulation is damaged, but the wires are still intact as shown in this photo.

    • Measure out a piece of heat shrink to be at least 1/2 inch (12.7mm) longer than the damaged length of the cord. Then cut that piece to size.

    • For a better fit on the cord try to use the smallest size heat shrink possible.

    • Note that you can cut the heat shrink using scissors, a box cutter, or any kind of knife.

    • Be careful with sharp objects.

    • Slide cord through heat shrink to check the heat shrink covers all of the damaged area.

    • It is easiest to slide through at the smaller end of the cord.

    • Then, keep the heat shrink on the cord but away from the damaged area for the next steps.

    • Glue Gun Method: Prepare the hot glue gun by plugging it in and allowing it to fully heat up.

    • Glue Stick Method: Prepare the glue stick by cutting off small pieces to use.

    • Note that you can cut the glue stick using scissors, a box cutter, or any kind of knife.

    • Be careful with the glue gun, temperatures get hot enough to burn skin.

    • Be careful with sharp objects.

Reinforcement of Frayed or Damaged Charging Cords, Applying the Prepared Hot Glue: step 5, image 1 of 3 Reinforcement of Frayed or Damaged Charging Cords, Applying the Prepared Hot Glue: step 5, image 2 of 3 Reinforcement of Frayed or Damaged Charging Cords, Applying the Prepared Hot Glue: step 5, image 3 of 3
    • Glue Gun Cont. : Apply hot glue in excess over the damaged area and then slide the heat shrink over that area.

    • Glue Stick Cont. : Without applying any hot glue, slide the heath shrink over the damaged area of the cord.

    • Feel free to be generous with the glue. Most effective repair will occur when the heat shrink is near-full of glue for either option.

    • Be careful with the glue gun, temperatures get hot enough to burn skin.

  6. Reinforcement of Frayed or Damaged Charging Cords, Filling  Heat Shrink with Glue: step 6, image 1 of 2 Reinforcement of Frayed or Damaged Charging Cords, Filling  Heat Shrink with Glue: step 6, image 2 of 2
    • Glue Gun Cont. : Completely fill the heat shrink with glue by placing the glue gun nozzle into the opening and fill the remaining space.

    • Glue Stick Cont. : Fill drop the small pieces of glue stick into the heat shrink. Firmly press the pieces in until they are tightly packed and the heat shrink is full.

    • Maintain even spacing between the walls of the heat shrink and the cord when applying glue.

    • Be careful with the glue gun, temperatures get hot enough to burn skin.

    • When enough glue has been added, apply heat from the lighter or other heat sources onto the heat shrink.

    • Be sure to apply heat in a back and forth motion. Alternative heating option can be hair dryer or heat gun.

    • Glue oozing out the sides is a good sign that you’ve applied enough.

    • Warning! Open Flame. Do not hold the heat source to one spot of the heat shrink or you will risk burning and damaging the cord.

  8. Reinforcement of Frayed or Damaged Charging Cords, Cooling and Finalizing the Repair: step 8, image 1 of 2 Reinforcement of Frayed or Damaged Charging Cords, Cooling and Finalizing the Repair: step 8, image 2 of 2
    • Let the repair cool then your free to tear off excess glue

    • Note how the glue is now fogged over, this means it has properly cooled.

    • Avoid cutting it off with a knife else you may redamage the cord.

Conclusion

To reassemble your device, follow these instructions in reverse order.
