hey guys i had a zune 30g and i bought an charger for it that allows me to plug the zune to via usb. it's was not really zune specific, it's not like a generic device, b/c it has no brand name on it but i think they claimed it as a zune device so it can sell. my question is that since i can also plug the ipod touch to that ac charger, can i use it? will it damage my ipod in anyway? it's inout is 100-240v. i mean they zune 30g take the same voltage as the ipod if not less right? can i use it without worrying?
