Question: Numark ICDMIX 2 Dual Cd Player

Eventhough this is a universal ipod docking station, will this insert any ipod out on the market (by Apple or any manufacturer) and/or any diameter in size to fit in the dock? I heard it might not take an Apple Classic ipod (true or not). Can you also tell me if it will charge the ipod in the docking station? Thank you
