This product addresses the issue of the STARLINK MINI restarting when powered by a 12V source. By adding this Anderson Connector in-line between your Starlink Mini and the 12V DC power supply, the problem is resolved. Users who have modified their Starlink Mini cable to connect directly to an Anderson connector on a 12V system may experience unexpected restarts without this in-line step-up adapter, particularly when using a smart alternator or a deep cycle/wet cell 12V battery.
