Goal: Longer charging cable.
Problem: Got better things on which to spend 12 bucks.
Solution: On hand, I have at least a dozen USB printer cables, and a box of various adapter.
So I took 2 printer cables, cut the "square" end off, stripped the wires, spliced 'em together, and slapped a male-to-female adapter on one end.
No go. Charges a "feature phone" from my junk box though.
