This not only holds your device but also adds a second power outlet to your vehicle.

The powered base is equipped with a USB port and a traditional DC power outlet with a maximum output current of 3A.  Use the same cable that is used to connect your device to your computer or use a car charger.  The cradle opens with a push of a button to a range of 1.25 to 4 inches.  This is wide enough to hold virtually any device.  And here's the best part, this mount will pivot and swivel into landscape or portrait mode.  The bottom of the cradle has an opening for your charger or other cables.
