The RAM Quick-Grip Wireless is a patented, universal waterproof wireless charging cradle for phones. As part of the spring-loaded RAM Quick-Grip family, this cradle allows for single-handed placement and removal of your phone while taking advantage of Qi wireless phone charging. Both the top and bottom cups feature rubber to help hold your phone firmly in place. To insert your device, use your phone to push the top cup upward and then gently place your device against the cradle for a secure fit. This Qi wireless charging cradle ensures your compatible phone charges as long as it’s within the listed compatible dimensions. For added security and peace of mind, a device tether is included that’s recommended for outdoor applications. This RAM Quick-Grip Wireless kit includes a B size diamond base featuring a 1″ rubber ball, short length double socket arm, and a RAM Tough-Claw clamping base. With the RAM Tough-Claw base, you can easily attach the wireless phone charger to round, square, and odd-shaped rails and bars ranging from .625″ to 1.5″ in outer diameter. The connected Type-A male pigtail connector features an in-line switch that allows you to turn off the wireless charging module when not in use. For in-vehicle charging, attach the pigtail to the included 1.2m Type-A male to Type-A female extension cable. This kit includes a hardwire charger.
