The Kensington Multi-Device Dual Wireless Compact Keyboard offers compact, portable typing for computer, tablet, or phone users. It connects and switches between up to three devices via Bluetooth (3.0 or 5.0) or 2.4GHz wireless and secures connections with 128-bit AES encryption. Smooth, responsive scissor keys and dedicated multimedia hot keys provide comfortable typing and easy access to common controls, and a low-battery indicator alerts you to replace the included two AAA batteries. Compatible with Windows, macOS, iOS, and Chrome OS, the keyboard's compact footprint suits tighter workspaces and on-the-go productivity, and its durable construction resists cleaning agents used for disinfecting.
