I ended up buying liquid tape for this fix, from my understanding you can buy colors but all I could find was black. After a few layers the split in the wire was gone and my charger was fixed. The rubber is not as thick as the original rubber but it works really well and fixed the split. The liquid tape was not too expensive and this took hardly any time at all.
