Improve your productivity with the Logitech Keyboard that supports up to three connected devices. The bright green channel on the keyboard's top edge allows you to connect to a tablet, smartphone, or other device with a comfortable viewing angle. As you type on one device, you can immediately switch to another by turning the knob on the K480 left side. Quickly complete both school and work projects regardless of what device you use because the device supports both Android OS and iOS. Simply install two AAA batteries and you will be able to type for several hours. In addition, it features all familiar shortcut keys that you need to copy, paste, and take screen shots.
