Looking for an external (secondary) battery pack for a 1st gen ipod Touch. The Mophie JuicePak is almost what I want (allows piggyback charging etc) but I don't understand why it uses a mini-usb connector (see 5th photo on mophie website) rather than the standard iPod dock connector? If it used the latter you could use the standard apple supplied usb->dock cable to charge it (and also if you wanted, to just charge the ipod). I'm not really into things that require a dedicated cable (even though usb->u-usb is somewhat of a standard) unless there is a good reason? Is there anything else out there? Also, if you have a skin on the Touch, will it fit into the JuicePak?
