It should have came with a usb cable so that you can transfer music between your computer and the player. You can also charge at the same time. However, I don't know if there is an ac adapter available for it. I just checked SanDisk's website and it doesn't appear to be one available.
Er...I hope I don't sound stupid, but I really need this question answered sometime in the next hour or so because that's the time period I have to buy whatever I need to buy for the Sansa c240. How is the battery on the player recharged? There is no AC adapter or charger.
Help A.S.A.P! Please!
