12v sockets

[Andyjack]

Hi while looking through the booklet and paperwork that came with my caravan i found this. Please see photo. It plugs into the 12v socket but i can’t work out what its use would be. Nothing can be plugged into it or so it would seem. It has a small plastic piece that lifts uo but to what purpose I don’t know. Any ideas please

Its a Hella DIN male cigarette lighter plug, that can be used on both 12v cigar sockets and the Hella 24v socket, hence the red adaptor. Personally I hate cigarette lighter sockets, the plugs are not properly secured. I replace the ones in our Swift with a double USB socket, far more useful.

But you cannot power an awning light, a tyre compressor or an awning inflation pump or a fair few other 12v items from a USB socket that only provides 5
