i'm not sure what generation it is. I know its white, a 20gb, clickwheel, non color screen. the charger i have seperate has a firewire plug in, cable from the plug in, to the connector that would plug into the Ipod. My firewire part is missing so I cant use the wall charger, and before when I plugged it into the computer, the screen used to come up saying Charging. So i knew it would charge from the computer. now it has the wall outlet picture.
i didnt wanna buy a new wall charger, because the cheapest i have found is $30, and im just missing the firewire cable for it.
