How to fix the infamous Nook Color / Nook Tablet charging USB cable for good?
I fixed the cable early before it was too late.

The problem zone is the hard transition from the connector to the cable. Shear force due to moving/bending the cable is very strong there when the cable is inserted into the Nook. This is the place where it starts to break and that needs to be fixed.

I consider this solution permanent as it hasn't broken in 18 months:

Add another coating to this transition to reduce shear force.

Used components:


superglue
2 pieces of heat shrink tube (different diameter)
