Review on 15ft Micro USB & Mini USB Dash Cam & Type-C Hardwire Kit with Mini/ATO Fuse, Battery Drain Protection & Port Adapters by Adan Hudson

I have this to power a USB DVR that is mounted on the windshield. The kit powers the camera normally, but I'm experiencing severe FM radio interference. An unshielded switching power supply must be available. I purposely placed it under the dash on the opposite side of the car from the radio antenna just in case, but the radio gets static once power is drawn. When I plug the dashcam into an old 12V socket, there is no static electricity. If I unplug the USB cable and leave it on but no load the radio is fine. I'm disappointed because I disassembled the dashboard, pillar and headliner to hide the wires and now I have to do it all over again. with a different power supply. I should have done some extra testing before installing :/ The kit itself comes with 4 different sockets for adding fuses, but I hardwired it to the back of the fuse box so I could use a regular fuse socket and not an add-a got fuse sticking out of the box.
