Lenovo Self-Charging Bluetooth Keyboard

The Lenovo 4Y41R69489 is a wireless keyboard that powers itself using ambient light. It features a full 108-key US English layout and connects to devices via Bluetooth. Integrated smart insights monitor brightness levels and supercapacitor capacity in real time. A USB-C port provides fast charging when a quick boost is needed.

Ideal for multi-device workflows

This keyboard suits professionals who switch between a laptop, tablet and desktop throughout the day. It supports Windows 10 and Windows 11 and charges under standard office lighting. Buyers who require a wired connection or dedicated macro keys should consider other options. The ambient charging system removes the need for disposable batteries.

Ambient light charging with 30-day reserve

The defining specification is the self-charging supercapacitor that harvests energy from indoor light. A full charge delivers up to 30 days of use in total darkness. This allows the keyboard to run indefinitely in a normally lit workspace without a cable.
