This is the full keyboard that allows you to type on a smartphone or a computer. The keyboard plugs into a Mac or PC via USB for traditional computer typing and connects to an iPhone or another smartphone wirelessly via Bluetooth to enable rapid typing on the smartphone. The keyboard switches between devices with the touch of a button and it has an integrated cradle that keeps an iPhone close at hand and its screen clearly visible. The full QWERTY keyboard has a number pad, arrow keys, and function keys for simple, more responsive typing on an iPhone. The keytops have a subtle contour to better accommodate fingertips while dome switches under each key provide a responsive feel and optimal resistance to hold the weight of hands. With two USB ports. Compatible with virtually all Bluetooth-enabled smartphones or tablets. Power for Bluetooth is provided by a connected computer. Specify Mac or PC. 18 3/4" L x 6 3/4" W x 1 1/2" H. (1 2/3 lbs.)
