The DuaLink Sync Splitter Cable from CableJive just made charging and syncing multiple Mac products that much easier. Simple enough, the DuaLink Sync Splitter Cable is an essential cord that will also work great with any USB charger.
I’m not sure if you can actually dual sync with this cord and it’s apparently not compatible with iPod Shuffle models. The cord is onsale for $26. Seems like a great idea.
