## Description

## NOCO GC003: X-Connect 12V socket plug (GENIUS chargers)

It is the answer when the battery is hidden (under a seat, behind a panel) and the vehicle has a 12 V socket. With the GC003, the GENIUS charges and maintains the battery through that socket; it fits standard sockets and, with the sleeve removed, the mini sockets found on many motorbikes.
Before choosing it, check that the socket stays live with the ignition off: if it cuts out, no charge gets through and fixed eyelets such as the GC002 (M6) or GC008 (M10) are a better bet.
An LED confirms power is flowing; it has a 20 A fuse and 71 cm of 16 AWG lead. For GENIUS1, 2, 5, 10, 2X2, 2X4 and G series.
