Apple Changed the voltage system in their products from 4th generation products upwards in 2007/2008. This meant charging problems with certain docking stations such as the Bose Series 1 / First Generation. This adapter will solve this problem.
This adaptor changes the charge voltage from 12V to 5V which will enable devices such as iPhone 3gs/4/4s, iPod's; Nanos, Classic iPod, iPad and iTouch etc, and it will charge your Apple device whilst your listening to it on your chosen docking station (no more draining the battery, and having to re-charge separately!
Works with any iPhone, iPod and iPad charging system that was designed to charge the older 12V Apple devices
For older docking stations e.g. Bose Series 1 / first generation etc. For 30pin iPhones, iPod Nanos, iPod Classic, iPad and iTouch etc.
