The male-to-male coupler works with NOCO Genius accessories and allows two accessories to connect to each other. A common use of the male-to-male coupler includes pairing GC002 eyelet terminal connectors or GC001 battery clamp connectors with the GC010 12 Volt plug female outlet to create a 12 Volt outlet directly from the battery. In addition, the coupler can be used for endless other applications paired with a variety of NOCO Genius accessories.
