The RAM® Tough-Charge™ with X-Grip® Technology is the world's first patented, universal waterproof wireless charging cradle for phones. Designed with spring-loaded RAM® X-Grip® Technology, this cradle features an 'X' design that expands and contracts to secure nearly any phone while taking advantage of Qi wireless phone charging. All four arms feature rubber-coated caps that hold your phone firmly in place, and the open design keeps buttons and switches accessible on the sides of phones. To insert your device, simply squeeze the arms on one side of the cradle and place your phone inside before releasing the arms. This Qi wireless charging cradle ensures your compatible phone charges no matter what position it's placed at. For added security and peace of mind, a device tether is included that’s recommended for outdoor applications. In addition, a support leg can be adjusted to the ideal position or removed altogether. This RAM® Tough-Charge™ with X-Grip® Technology wireless charging 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 1.14” 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.
