The cigar lighter is indeed the one next to the driver's right knee (on LHD vehicles... if you have a RHD, disregard

), the remaining sockets are for accessory 12V power only. If the cigar lighter is the one not operating, insure the problem is really with the socket and not with the device / charger you are trying to plug in. Because that particular socket is designed to accept a (duh!) cigar lighter, it doesn't always play nice with phone chargers, power cords, etc., which normally work just fine in the remaining 3 sockets in the car (which were not designed as cigar lighters and are designed differently inside.) The cigar socket will work eventually as a source of 12V power, but it will sometimes require quite a bit of plug twisting and pushing before you get juice flowing to whatever it is that you are trying to power.
