If it charges the adapter is probably going to be an iPod dock connection. Yes you can rip CDs and put mp3s on an iPod. I'm pretty sure you have to use iTunes to get music onto the iPod, unless you're using it in disk mode, but then i doubt it would work in your car or as a portable rock out device. You won't be able to put wma files on it but I'm sure you can find a program somewhere to convert your files to a compatible format.
