Maybe a dumb question but is it possible to charge an IPod through an IPAd. For instance could it be done through the camera connection kit. This year, on vacation we will take only our IPAD and not our MacBook which we always used to charge the IPods. I know we can buy a wall charger but that is one more little electronic gadget to carry and between my razor, cell phone, IPad etc. I already have too many chargers to carry.
