The CHERRY KW 9100 SLIM not only looks fabulous, but also offers numerous extra features, state-of-the-art technology and high-quality workmanship. The extra-flat keyboard can be connected via Bluetooth. Data transmission uses AES 128 encryption and a range of up to 10 meters is also sufficient for use with a TV or game console. The built-in rechargeable battery allows you to work for weeks without charging the keyboard, but after that, simply plug the included USB-A to USB-C cable into a free port to recharge even while working. To ensure the rechargeable batteries remain charged in long periods of inactivity, the keyboard can be powered off with a simple on/off switch. The wireless keyboard is fitted with a built-in metal plate for maximum stability and rigidity. If you prefer a steeper angle while typing, you can adjust it using the removable magnetic bar. CHERRY's own SX scissor technology mechanism with a low-profile keystroke ensures an ideal typing experience.
