This K480 universal wireless keyboard lets you type on your laptop, tablet or smartphone using a wireless Bluetooth connection. Switching between devices is simple using the handy Easy-Switch dial, so you can have multiple devices connected at the same time for quick access, while a handy integrated cradle holds your tablet or smartphone at a comfortable typing angle. A battery life of around 2 years with daily use means battery changes will become an extremely rare thing, and there's a battery life indicator to let you know when power is running low.
