My original dash-cam used a USB C connector. It stopped working, but I had another "spare" in the garage BUT it used Mini-USB!. I really didn't fancy spending many many hours trying to thread yet another cable up the door pillar!. So I wondered if there was an adaptor available. YES!, this arrive the next day, very well made, great value, and once installed, hardly noticeable. It's also well shielded too, important, as the cam is mounted right beside the windscreen antenna. Very happy.
