A few months ago I bought a car just to get to work with and I don't use it for anything else. It only has a cassette player in it so I went to Wal-Mart and got this cassette adapter kit to play my MP3 player through my car cassette deck. It came with this little universal car charger that you connect to the mp3 player. It came with a large number of different tips and a voltage selector. I charge my mp3 player through USB and I already have a car charger for it so I put it on a shelf for a few months. I got my M001 today and so I dug it out and I was pleasantly surprised to see that it worked great! Had the perfect tip and everything. So yea, check Wal-Mart if you have one around, got it on sale for like $10.
