Im leaving on a trip in five minutes and don't have time to google or search these forums so forgive me if this one of those asked all the times. I have my daughter's ipod nano, the little square kind. We usually charge it by plugging it into the little dock it came with and then hooking that up to a usb port. We won't have a computer on our little trip but can I take the wall plug part of my iphone 4 charger and hook that up to the ipod nano dock via the usb connection? I don't care if it is a really slow charge, I just don't want anything to break. Thank you for your advice in advance.
