Original Arkon Universal Mega Grip Dashboard Mount w/ Universal Cradle, SM428 - Black Your car's 12V / 24V accessory outlet is a convenient and unique location for mounting your cell phone. With Arkon's SM421, you're able to hold the phone securely from the outlet slot. The power dongle acts as the primary charging outlet since the car's outlet is being used up by the lighter socket pedestal. Arkon's Mega Grip holder is not phone specific, though it works with nearly all phones including those that have protective cases or skins on them. SM421 is better suited as a mount for your phone's handsfree calling, or to keep your phone within close proximity. The lighter socket location is usually not ideal if using your phone with GPS (see the SM410, SM412, SM415, SM416, SM428, or SM429-SBH instead).
