12V auxiliary socket charging
The GC003 connects to the X-Connect port on compatible Genius and G Series chargers, allowing you to charge and maintain your vehicle battery through a standard 12V or mini 12V auxiliary socket. A built-in power LED illuminates when 12V power is active. Check that your vehicle does not have an ignition-controlled socket shutoff before use.
Dual-size plug — standard and mini
The plug fits both standard 12V ports and mini 12V ports, making it suitable for cars and motorcycles without needing a separate adaptor.
Built-in fuse protection
A 20A mini-blade fuse is built into the cable for safety and overcurrent protection. If you need an eyelet-based connection rather than a 12V plug, NOCO also offer the NOCO GBC007 Boost Eyelet Cable with X-Connect Adapter.
