Lenovo Professional Wireless Rechargeable Keyboard (Black)

The Lenovo 4Y41K04031 is a professional wireless rechargeable keyboard that brings desktop-grade comfort to anyone who moves between several devices during the day. Whether you write reports on a laptop, answer messages on a tablet, or run presentations from a phone, this keyboard lets you stay on the same set of keys while each device stays connected.

Switching is simple. A single button press toggles among up to three paired devices through Bluetooth or the included 2.4 GHz USB receiver. This flexibility is helpful for remote workers who manage a work computer, a personal computer, and a mobile device, as well as for shared meeting rooms where different presenters need fast handoffs.

The full-size layout includes a separate number pad, navigation cluster, and function row, so spreadsheet tasks and data entry feel natural. Scissor-switch mechanisms make every key press quiet and consistent, a useful trait in open offices or late-night study sessions when you want to avoid distracting others.

Lenovo uses 65 percent recycled materials in the chassis, so you can support sustainability without giving up performance. The finish comes in grey that looks sleek beside modern laptops and monitors.

A built-in battery keeps the keyboard running for as long as three months on one charge. When it is time to top up, connect the supplied USB-C cable and keep working while power flows in.

For teams that handle sensitive information, AES 128-bit encryption protects keystrokes over both wireless links. You can also remap the programmable function keys to launch apps, control media, or trigger shortcuts that match your workflow. The keyboard weighs only 20.67 oz, so packing it for business travel or hot-desk environments is easy, and a three-year warranty backs your investment.
