Deal | This self-charging battery-free Bluetooth keyboard drops to $61.35 (28% off)

At CES 2025, Lenovo unveiled the Self-Charging Bluetooth Keyboard, which has a fast-charging supercapacitor that stores energy instead of a battery, and photovoltaic cells that draw power from ambient light to charge the supercapacitor.

When the keyboard, which is also known as the Lenovo 800 Self-Charging Bluetooth Keyboard, was announced at the tech show, Lenovo said it would cost $69.99. However, it was a surprise when it was released in the second half of 2025 for $99.99. Now, the keyboard is on sale, and the best part is that, it is even cheaper than the CES launch price.

The Lenovo Self-Charging Bluetooth Keyboard is available to buy on Amazon for $61.35, and that price gets you the grey/black version, which has mostly black keys and a few green keys. The white version with all-white keys is a tiny bit more expensive at $62.99. The keyboard is also available to buy directly from Lenovo for $63.74, but you can only purchase it in gray/black.

The Lenovo Self-Charging Bluetooth Keyboard is a full-sized keyboard with island-style keys and a numpad. It has Bluetooth 5.1 and is capable of connecting to three devices simultaneously, with dedicated keys for switching between paired devices. Lenovo claims owners will be able to use the keyboard for up to a month without charging it when used in a dark room without ambient light.

It is also spill-resistant, has adjustable tilt legs, and features a USB-C port that can be used to quickly charge it if there's no ambient light. There's an LED ring at the top that shows light levels and the battery level. Owners can also use the Lenovo Accessories and Display Manager (LADM) software to monitor brightness levels, check connected devices, and customize keys.

The Lenovo Self-Charging Bluetooth Keyboard is compatible with Windows 10 and 11 devices and has support for Microsoft Swift Pair. It also comes with a 3-year warranty.
