Hi, I'm trying to find a power adapter for my Medion Sat Nav and I need one which is 3.0mm wide. I tried the power adapter that came with my mobile phone, but its too big at 3.5mm. My Sat Nav came with a car charger which has a 3.0mm end to plug into the Sat Nav, but I also want a power adapter so I can plug it in and charge it at home. Does anyone know where I can find a power adapter whose end is 3.0mm wide? Thanks for your help.
