The Blackvue Power Magic EZ is a charging station for your Blackvue dashcam. This allows you to film for a long time when your car is switched off. You connect the Power Magic to the OBD port (on-board diagnostics) of your car. Set the timer function from 6 hours to infinity so that the dash cam is automatically switched off in parking mode. The Volt setting automatically switches the dash cam off after the voltage drops below the set value. For example, the dashcam does not consume all power from the car in parking mode. This will prevent problems with starting the car when you continue your journey.
