I am going on a trip to Italy for school and since the plane ride and waiting in the airports will take forever I needed a way to charge my mp3 player and if you have a sansa c250 you know there isn't a lot of accessories for it. One of the things I was afraid of was, that like when plugged into a computer, you cant play music from the mp3 player when it was charging. I tried it out and you can still play while charging. While I haven't gone on the trip yet, so far it is everything I needed
