ROLLING SQUARE INCHARGE-X REPLACEMENT ENDCAP

The Rolling-Square collection of multi-purpose InCharge-X USB cables are excellent products.

However, when in use, you have to take the end-cap off.
If you're like me, this gets put in a dark office drawer and migrates through a wormhole to another planet where it can live out the rest of it's life in peace and quiet.

This model is a reverse-engineer of that end-cap.
