The adjustable brackets expand to fit most smartphones up to 3.3 inches wide, including the iPhone, Samsung Galaxy, and Nokia Lumia. The vent mount cradle securely attaches your iPhone 5/5s, iPhone 6 Plus, iPhone 6, or other compatible smartphone to an air vent on your car's dash for convenient eye-level viewing-no suction cup or adhesive required. It even works with a case on. Position your smartphone for viewing in either portrait or landscape mode. Portrait mode is ideal for charging, listening to music, and making hands-free phone calls, while landscape view makes using your favorite navigation apps easier. A cable holder on the back of the mount keeps your phone's connector tangle-free so it stays neatly connected to your device.
