The BlackVue BOC-300 OBDII Power Cable is a 3-metre long power supply cable designed specifically for BlackVue dashcams. It enables users to power their compatible BlackVue dashcam models directly from a vehicle’s OBDII port, simplifying installation by eliminating the need for hardwiring to the fuse box. The cable is plug-and-play, supports constant power for parking mode, and is suitable for both professional and DIY installations. Its design minimises installation time and allows easy dash cam transfer between vehicles equipped with OBDII ports.
