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.

If you don't already have sugru, you can get it directly from us at sugru.com

Step 1: Getting ready

You have about 30 minutes to work with sugru before it starts to cure so you have plenty of time.

Open one mini pack (5g) of sugru with a scissors cutting along the dotted lines.

Peel open the mini pack.

Remove the sugru and knead it in your fingers for around ten seconds.

Shape the sugru into a flat sausage roughly 40mm in length.

Wow this is awesome stuff, thanks.
This is fantastic. I have some sugru sitting around and I was just thinking about how awful my ipod cable is looking. :)

Not only is this a good repair method but could also be use before any damage has been done as a preventative measure, as this is a common place for power cables to fail.

Looks great!

I've done something similar with epoxy and black paint. It worked well, but was a little sticky for a while. This probably works better.
