The oval shape of the iSHOXS Power Force Cup ProX, smartphone / cell phone holder for cars, is a completely new concept and redefines the limits of holding power. Extreme grip through the Membrane to Body-Lock system (patent pending) on smooth surfaces, especially on car windshields. We have integrated two eccentric levers into the suction plate, thus ensuring a very stable connection on smooth surfaces! The increased holding force even allows an extension to be mounted for a secure hold of the cellphone / smartphone. In the case of the iSHOXS Power Force Cup ProX Traffic, it is a stable extension arm, adjustable in angle and a length of 11" to 12 3/4" (280mm to 325 mm). In combination with our new cell phone and smartphone holder iSHOXS C-Mount, this allows a safe and optimal positioning of your device on the dashboard without restricting the view of the traffic. The integrated 90° switch allows to rotate the smartphone in 90° steps to switch from portrait to landscape orientation. Due to the open C-shape, the ports on the top and bottom of the device remain operational. The construction-related distance between the device and the C-mount reduces overheating of the device. The 3 included sizes of the C-Mount fit all popular smartphones from Apple, Samsung, Google, OnePlus, Huawei and Xiaomi with widths from 2 3/4" to 3 5/16" (70mm to 85 mm).
