This. It's not worth your time and effort repairing a cable when you can just buy one for around $12. Also take care of your cables, take like 10 seconds to wrap it up properly when you store it into your bag or buy two cables + another charger so you avoid coiling and uncoiling the wire frequently. I've had my Matebook X Pro with the original cable and it has no signs of wear. These cable end protectors help a good amount as well.
