BlackVue OBD-II Power Cable

In terms of functionality, the OBD-II cable essentially achieves the same result as hardwiring your dash cam to your vehicle’s fuse panel. It supplies power to the dash cam even when the vehicle is parked, and the BlackVue monitors the power level to shut down if the voltage drops too low (you can adjust the cutoff level using the BlackVue App).

The main advantage of the OBD-II Power Cable is its convenience. Simply plug it in, and you’re all set. It’s likely the easiest solution for enabling Parking Mode.

All BlackVue dash cams that have a built-in voltage monitor are supported. In other words, the BOC-300 supports most models since the DR750X/DR900X Series. If your BlackVue dash cam came with a Hardwiring Power Cable (with yellow, red and ground wires), then it is compatible with the OBD II Power Cable.
