Does your ipod charge while its off if you plug it up?
Yes,every iPod is like that I believe. From The iPod Classic,to the Nano's,to the 3rd Generation Nano,to the iPod Touch & Phone,etc.
yeah it will charge while it's off... it actually charges faster that way.
your ipod will charge if the ipod is off but not if the computer isnt
yep I think so :)
