The iOttie Auto Sense 2 Wireless Air Vent Mount is a Qi-certified car mount designed for maximum convenience and power on the road. Mount your smartphone in seconds thanks to the auto-sensing feature powered by a proximity sensor. Simply place your phone near the mount cradle to engage the silent servo motor and the arms will automatically open and close to secure the device. Once mounted in the cradle, Qi wireless charging technology delivers up to 10W of power to the smartphone automatically without the need for additional charging cables. A series of ventilation holes constructed around the mount cradle help to dissipate heat and maintain airflow for a more efficient charging experience. Retrieve your phone by tapping either of the release buttons located on each side of the cradle with a quick one-handed motion. The internal battery stays charged for up to one hour after your vehicle is shut off. The Auto Sense 2 quickly and securely installs on both horizontal and vertical air vent blades where rubber prongs provide a vise-like grip and prevent the car vent phone mount from slipping. Once attached, you can easily adjust the mount to find your perfect viewing angle thanks to a versatile ball joint that rotates, swivels, and tilts a full 360degree(s). Experience a safer, more convenient driving experience with the Auto Sense 2!
