As I take my Sansa Clip on trips without a computer easily accessed. (I would probably have to beg someone to charge my player on their computer). Is there an AC adaptor/car adaptor for the Clip. The website is confusing as the product shown is a 30 pin adaptor. Also I have a Garmin NUVI 350 GPS which has the same size plugs as the Sansa Clip. Can I use these to charge the Sansa or will it fry it?
