There are so many USB charging options available these days — from solar chargers to wall hubs to portable chargers. But, iPods always required their own proprietary plugs and chargers. SendStation has come up with a very handy option.
The PocketDock Line Out Mini USB (that's a mouthful) plugs into the iPod connection and combines a mini USB output and a line-level output so you can plug the iPod into a home stereo or powered speaker system. It's smaller than previous versions, and is the same size as a typical iPod plug. The $30 adapter comes ready to go with a set of cables and it's Made for iPod certified. Not a bad price to be able to use one set of cables to charge all your portable devices.
