Query: Maybe i got a defective one?

Im just baffled as to what happened. This little charger worked great for maybe a week? Then all of a sudden, we tried plugging in our little E260 sansa and it registers that somethings plugged in but it doesn't actually charge anything.Weirdest thing, i wonder if we blew this little unit, but it doesn't do anything. Plug it in, sansa turns on, wait a little bit, sansa turns off.... nothing happens. Have tried leaving it plugged in all night, nada.Weird?
