12V extension cable for cigarette lighter, with 1 waterproof socket

Who doesn't know them, the not really cheap 12 V extension cables and adapters from the DIY store? Usually quickly packed just before a trip, disillusionment soon sets in when devices do not work/charge properly due to wobbly plugs, fuses permanently blow because the cables are too thin or there is a short circuit due to moisture penetration.

The length of the list of product features shows how much effort and thought has gone into the two cables offered (with one or two sockets):

• rubber seal on the plug to prevent dust and moisture penetration
• control LED and 10 A fuse integrated in the plug
• integrated strain relief to protect the cable
• waterproof cap on the socket
• locking system for secure fit (requires corresponding socket)
• Integrated strain relief to protect the cable
• all contacts nickel-plated for low contact resistance
• mountable and dismountable (with suitable adapters)
• available with one or two sockets
