Lenovo has also announced a handful of accessories, including a self-charging Bluetooth keyboard. The keyboard has solar cells that can draw power from ambient light to charge supercapacitor inside, eliminating the need for batteries or to plug it in to charge.

While plenty of focus will be on Lenovo's new computers and Legion gaming devices, the manufacturer also has a number of interesting accessories such as a self-charging Bluetooth keyboard. The device, which first leaked a few weeks ago, has an exterior made from 95% post-consumer recycled plastic. However, what makes it interesting is that it wouldn't need to be charged.

The Lenovo Self Charging Bluetooth Keyboard has photovoltaic cells that allow it to draw power from ambient light. It also has a fast-charging supercapacitor in place of a traditional battery just like HP's rechargeable keyboard and mouse combo. Unlike a traditional battery, a supercapacitor can store high capacity energy and can charge incredibly fast.

Lenovo claims the keyboard will last up to 45 days in a completely dark environment before needing to be recharged. When the power is depleted, all it needs is 2 minutes of charging under a light source of 300 Lux intensity to get it back on for use.

The Lenovo keyboard is also spill-resistant, has adjustable tilt legs, dedicated media controls, and has a three-zone layout with on-screen brightness indicators. Using the Lenovo Accessories and Display Manager, users can also track in real-time the device's power.

The keyboard also has Bluetooth 5.1, support for Microsoft Swift pair, and multi-device support (up to 3 devices). It is compatible with ChromeOS, Windows 10 and newer, macOS, iPadOS, iOS, and Android devices.

The Lenovo Self-Charging Bluetooth Keyboard will be available in May 2025 for $69.99. It will be available to buy in two colors.
