The RAM Quick-Grip Wireless is a patented, universal water-resistant 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 compatible wireless phone charging.

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 compatible 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 for vehicles includes a B size diamond base featuring a 1-inch rubber ball – perfect for attaching to your choice of B size RAM double socket arm. 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.
