for dashcam. After a small renovation of the USB connection cable, this adapter fits to the E-Prance Full HD. Simply unsolder USB cable from the cigarette lighter adapter and solder back to this little adapter. Since the housing is screwed, that's not a big problem. On this occasion, you might as well the small toroidal coil fix with a little hot glue because it is held only by the relatively thin connecting wires to the board, and thus a broken wire is pre-programmed by vibration. After this small modification of the small adapter does the job well at the E-Prance.
