Hi! On one of the sides in our Kon-tiki is a normal UK 3 pin plug socket and next to it is a small circular socket that looks like a cigarette lighter socket, but smaller - about 13mm in diameter. Can someone please tell me what the socket is called, and what's available to fit it? We're not intending to hook up to the mains too often when we're out and about so if we could get an adapter to fit the socket (I assume it has to be 12v) that will charge our phones from the battery, for example, it would be a great help. I already have a cig lighter socket with a USB port that I'm thinking of plugging a USB hub into, but more USB ports wouldn't hurt as this round socket is in a more convenient location than the dashboard.
