Take a closer look at the passPORT Home Dock iPod adapter from Scosche.
Scosche passPORT HomeDock
The Scosche passPORT HomeDock retrofits old 12 volt-powered iPod docks to output the 5 voolts required to charge newer iPods and the iPhone. The adapter fits within Apple's universal dock, adding a half-inch to the dock's height.
Placing the Scosche passPORT HomeDock in an iPod dock adds about a half-inch to the dock's height. Depending on the product's design, this extra height might make it impossible to fit your iPod, or in this case, fold up the retractable dock.
Many users of the original Bose SoundDock have been clamoring for an adapter like the Scosche passPORT HomeDock, since the system has no way of playing audio from any other source aside from the iPod Dock. Scosche even includes an adapter ring specifically for the SoundDock, which makes the fit a little more attractive to look at.
The Scosche passPORT HomeDock will adapt older docks to charge your iPhone, but it doesn't add iPhone certification to older accessories. You'll still get a nag screen to warn you that the attached accessory isn't made for the iPhone.
The Scosche passPORT HomeDock comes in one of the most obnoxious double-sealed blister packs we've ever seen. Not only do you risk injury trying to remove the product, but you end up with an unforgivable amount of plastic packaging waste for such a tiny product.
