How to repair a laptop charger

Technology is constantly changing the world, but some things never change. Cables on laptops, phones and tablets will ALWAYS fray. Replacing the charge on an expensive new laptop seems like an unfair additional cost, luckily it’s one that can easily be avoided. 

So long as the cores are not damaged or exposed and the cable still works, then Sugru Mouldable Glue can fix it! Sugru is perfect for this because it bonds brilliantly with cables and turns into flexible rubber once set, so you can still move it around freely.

KIT:

  • Your broken cable

  • One single-use pack of Sugru

  • CARE: Be careful with electricity. Stick to small consumer electronics repairs, low current and below 24 volts. To avoid heat build-up from short circuits or damaged wires, do not repair cables where the metal is exposed or the cable is already working intermittently. We don’t recommend it for DIY electrical work on items with higher voltage. 

Step 1

Tear open your single-use pack of Sugru and knead it for approximately 30 seconds. Roll the Sugru out until you create a long sausage that can comfortably wrap around the cable.

Step 2

Press the Sugru together and to the cable to ensure a good bond. Make sure it is firmly attached to the plastic casing of the power block and covers the cable for about the width of your hand, to provide a good strain relief.

Step 3

To give Sugru a great smooth surface finish, gently and firmly rub the Sugru to get rid of all the fingerprints and cracks. Hang the cable from a table or desk with tape to allow the Sugru to set.

After 12-24 hours, your Sugru will be set and ready to go. Fixed, flexible and fun! Woohoo!
