This is the speaker dock that charges an iPhone and iPad simultaneously. Two dedicated 30-pin dock connectors hold each device upright, providing a convenient charging platform that requires as little space as a box of tissues. The dock plays music from either device through the unit's dual integrated stereo speakers, allowing you to watch videos or listen to a music collection while an iPad and iPhone charge (devices must be removed from case to dock). A built-in 3.5 mm audio port also accepts connections from an iPod or other MP3 players. Powered via an included USB cable that connects to a (not included) USB-to-AC adapter. Compatible with iPhone 4S, 4, 3GS, iPad/iPad 2, and iPod touch models. 11 1/2" W x 5" D x 1 3/4" H. (1 1/3 lbs.)
