Dash Cam Power Kits
Power for a dash cam that keeps recording while parked: OBD2 to USB and OBD to USB-C power cables with 24-hour parking mode and an ACC mode switch, and a 5V 3A USB-C hardwire kit with low-voltage battery protection. Choose by the connector your dash cam uses.
How to choose: a hardwire kit powers the dash cam without using the 12V socket and keeps it running in parking mode. Choose one with low-voltage protection, which cuts power before the car battery runs down, and match the plug (USB-C, micro USB or mini USB) to your camera.
