Does what it says on the tin. Charges my old MS Zune. I was surprised that the battery still holds a charge. However, now I'm an Apple Mac user and have yet to find software or some sort of interface that would allow me to transfer music, movies or files in general to my 30GB Zune. Incidentally, I dusted off my 30GB Zune after seeing it as a StarLord music player when its Sony Walkman cassette player was destroyed in Guardians of the Galaxy Vol.
