Hi fideldavila,
Do USB chargers work?
I was looking for a USB charger for my iPod Shuffle and the sales person at the Apple store told me about a Belkin USB hub made for the iPod Shuffle. Its a USB hub with a cradle usb on the top for the Shuffle and 4 usb ports on the side. I love it, works great!
