This backup power source is used during battery replacement. It prevents memory loss of the vehicle's clock, navigation, and audio systems by supplying power in place of the battery. It requires a mobile battery or portable power source (sold separately) that can output 2A or more. The connection to the vehicle is made via the OBD2 connector, allowing for easy and secure use without hindering battery removal. It features three LED indicators to show the status of the USB power source, connection to the vehicle battery, and backup power supply status.
