Lenovo Professional Wireless Rechargeable Keyboard & Mouse Combo

The Lenovo 4X31K03931 is a professional wireless keyboard and mouse set that takes everyday computing tasks and makes them smoother, quieter, and easier on both you and the environment. It combines a full-size keyboard that uses scissor switch keys for a soft, precise feel with a mouse that offers an adjustable sensor up to 4000 DPI, so you gain fine control whether you work on spreadsheets or creative designs.

Typing on the keyboard feels familiar right away because every key sits exactly where you expect it. The scissor switch mechanism dampens noise, which is helpful in shared offices, classrooms, or late-night home setups where you want to stay productive without disturbing others. AES128 encryption protects each keystroke, giving added peace of mind when you enter passwords or sensitive data.

The included mouse fits naturally in the hand thanks to a shell made from bio-rubber that stays comfortable through long sessions. Eight programmable buttons let you create shortcuts for frequently used commands, while the adjustable DPI range lets you move from pixel-accurate editing to rapid on-screen navigation with a quick tap.

Both devices feature internal batteries that recharge through USB-C and can last for as long as three months on a single charge, so you spend more time working and less time hunting for disposable batteries. A single 2.4 GHz wireless dongle or Bluetooth connection lets you pair with up to three different computers, tablets, or even phones and switch among them almost instantly. With housings made from 65 percent recycled material, the combo also supports sustainability goals for businesses and individuals who want to reduce electronic waste.
