Laptop power chargers and USB cables always break at the same point and once they do, it's not long before they stop working altogether.
Here are instructions to show you how to repair this problem quickly and very easily using sugru.
Just to state the obvious, your cable needs to be in working order before you use sugru to make this strain relief... Why use sugru ?
1: sugru will bond to the cable and the power block.
2: sugru cures to a flexible silicone rubber which means that it is unlikely to break again.
3: sugru is an electrical insulator.
