This weatherproof DIN accessory socket is designed to be panel-mounted on a vehicle to provide an external charging point and power outlet socket. It is the same format as is used on some Triumph, BMW and Honda motorcycles. In addition to providing a weatherproof connection point for your OptiMate charger using an optional accessory plug lead, it also provides a power outlet socket for other accessories - e.g. mobile phones, tyre pumps, portable CD players, notebook PCs, GPS navigation units, camping lights, etc. It is of particular use for scooters with sealed battery compartments and any vehicles where use of the standard fused permanent lead is not practical.
