The CableJive dockXtender makes it easier to use your iPhone or iPad with a dock. The cable has a female Lightning connector that plugs into your dock, and a male Lightning connector for your device.
The dockXtender's plug is slim enough to fit through the opening of almost any iPhone 5/5S case. So you can leave your iPhone in its case as you dock and sync it. Most docks have recessed plugs, which won't work with an iPad. The dockXtender takes care of that problem, letting you connect your iPad to the dock.
The dockXtender allows full functionality, the same as if your device was plugged directly into the dock. The connectors' rugged build ensures they'll hold up to daily use. And the cable puts all the video and audio signals on a shielded path to prevent interference from data and other signals traveling through the dockXtender
