The SM621 lighter socket car mount fits large smartphones up to 6.75” tall (8” screen size), including the iPhone 6S and 6 Plus, 6S, 6, 5, 5S, 5C, and 4S, Samsung Galaxy Note Edge, Note 5, Note 4, and Note 3, Galaxy S7 edge, S7, S6 edge+, S6, S5, and S4, LG G5, G4, and G3, Nexus 6 and Nexus 5, HTC One M9, One M8 and One Max, Nokia Lumia 1520 and 1020, Motorola Moto G and Moto X. It also holds midsize (7” or 8” screen size) tablets, including the iPad mini, Galaxy Tab S 8.4, Galaxy Note 8.0, Galaxy Tab 4 or 3 7.0 and 8.0, Galaxy Tab Pro 8.4, Kindle Fire HD, and Google Nexus 7. The mount includes Arkon’s Slim-Grip Ultra spring-loaded universal holder and lighter socket mount with integrated power dongle. Connect your phone’s car charger (sold separately) to the 12V power dongle on the mount while your phone is mounted to the car’s accessory outlet or cigarette lighter socket. The smartphone or tablet is held securely in place with the patented spring-loaded holder, but can be inserted or removed from the mount with one hand. The top and bottom adjustable-leg design of the Slim-Grip Ultra helps keep any side buttons and ports unobstructed, making it ideal for use with the side accessible buttons on the Samsung Galaxy S7 edge or Galaxy Note Edge. Included with the holder are 8 support legs (4 short and 4 longer versions) that can be customized based on device size. The recommended configuration for most smartphones and midsize tablets is to have 2 short legs on the top of the holder and 2 of the longer legs on the bottom of the holder. This mount fits all non-flip smartphones, even those with ruggedized or large protective cases or skins. Loosen the wing nuts to adjust the mount up to a 90° angle, and the swivel ball adapter head provides 360° rotation for ultimate flexibility. Garmin GPS devices can also be mounted to the car’s charging outlet or cigarette lighter socket by simply unscrewing the swivel ball adapter head and revealing the 17mm ball mount base.
