## Description

## NOCO GC018: 12V socket with M10 eyelets (fixed battery mount)

Designed for anyone who wants a fixed 12 V socket next to a large battery (a boat’s or motorhome’s leisure battery, for instance) to run an inflator, vacuum, coffee maker, fan or cool box.
If the battery is small or you need to fit and remove it often, the GC017 combines micro clamps and M6 eyelets. Neither is X-Connect: they do not connect GENIUS chargers.
The M10 terminals are flat and copper-plated to improve contact without damaging the post. 100% copper 16 AWG cable, 61 cm long, 15 A rating, 20 A fuse and a weatherproof cap.
