Since my dream of a UV-3R refresh with Bluetooth app interface and USB-C charging (among other updates) looks like it will remain in the relm of fantasy, I thought I'd give USB-C charging mod a go myself... surgery was successful and pretty straightforward, though I did botch the hole on the plastic case, making it way too big (I'll have to go back in and fill it with something later).
At least now I won't have to use a proprietary charger! Finding a spot was a challenge, but the second image is a rough location where I was able to locate and JB weld the adapter at, once I cut away a small bit of the metal case to make room (the picture is before the cut). Wiring was silly simple, connecting the positive and negative to the breakout board with the positive and negative of the barrel connector SMD
