    Lenovo’s Self-Charging Bluetooth Keyboard Now Available for Purchase

    Key Takeaways

    1. The Lenovo Self-Charging Bluetooth Keyboard was initially priced at $69.99 but is now available for $99.99, a $30 increase.
    2. It features a supercapacitor for energy storage and a photovoltaic cell to harness power from ambient light.
    3. The keyboard can last up to 1 month on a full charge, which is shorter than the 4 months claimed by a competitor’s product.
    4. It has 108 island-style keys, a dedicated number pad, a low-profile layout, adjustable tilt legs, and a spill-resistant design.
    5. The keyboard connects via Bluetooth 5.1, is compatible with Windows 10 and 11, and can be managed with the Lenovo Accessories and Display Manager app.

    Announced back in January during CES 2025, the Lenovo Self-Charging Bluetooth Keyboard was initially set to hit the shelves in May, but that date came and went without a release. Now, this keyboard is finally up for purchase, but the unfortunate news is that it comes with a higher price tag.

    Pricing Details

    When Lenovo first revealed this keyboard at CES 2025, they mentioned it would be priced at $69.99 upon its May release. However, the current price is $99.99, which is a $30 hike from what was originally expected. Currently, the keyboard is only offered in black, and there are no updates regarding the potential release of a white variant.

    Unique Features

    What sets the Lenovo Self-Charging Bluetooth Keyboard apart is its lack of a traditional battery. Instead, it utilizes a supercapacitor for energy storage. At the top, there is a photovoltaic cell that enables the keyboard to harness power from ambient light, eliminating the need for direct sunlight exposure.

    For those who prefer working in low-light conditions, there’s a USB-C port available for emergency charging. Once fully charged, the keyboard can last for up to 1 month of usage. This duration is significantly shorter than the 4 months claimed by the Logitech Signature Slim Solar+ Keyboard, which is currently available on Amazon for $99.99.

    Specifications

    The Lenovo Self-Charging Bluetooth Keyboard features 108 island-style keys, complete with a dedicated number pad. According to the specifications, it has a low-profile 2.5 zone keyboard layout designed for quiet typing. The keyboard also includes adjustable tilt legs and a spill-resistant design. It connects through Bluetooth 5.1 and is compatible with Microsoft Swift Pair. Lenovo states that it works with devices running Windows 10 and 11, and can be managed using the Lenovo Accessories and Display Manager app.

    Lenovo’s Solar-Powered Self-Charging Keyboard at CES 2025

    While there will be much attention on Lenovo’s latest computers and Legion gaming gear, the company is also introducing a variety of fascinating accessories, including a unique self-charging Bluetooth keyboard. This device, which was first revealed a few weeks ago, boasts an exterior made from 95% recycled plastic sourced from consumers. The standout feature of this keyboard is that it doesn’t require conventional charging.

    Innovative Charging Technology

    The Lenovo Self-Charging Bluetooth Keyboard incorporates photovoltaic cells, enabling it to harness energy from surrounding light. Instead of a standard battery, it employs a fast-charging supercapacitor, similar to HP’s rechargeable keyboard and mouse set. Unlike traditional batteries, supercapacitors can store large amounts of energy and recharge at an astonishing speed.

    Impressive Power Life

    According to Lenovo, this keyboard can function for as long as 45 days in complete darkness without needing a recharge. Once the energy runs out, it only takes 2 minutes of charging under a light source with an intensity of 300 Lux to restore it for use.

    User-Friendly Features

    In addition to its innovative charging, the keyboard is designed to be spill-resistant and comes with adjustable tilt legs, dedicated media controls, and a three-zone layout complete with on-screen brightness indicators. Users can also monitor the device’s power in real-time through the Lenovo Accessories and Display Manager.

    This keyboard features Bluetooth 5.1, supports Microsoft Swift Pair, and can connect with up to three devices simultaneously. It is compatible with various operating systems including ChromeOS, Windows 10 and later, macOS, iPadOS, iOS, and Android.

    The Lenovo Self-Charging Bluetooth Keyboard is set to launch in May 2025, priced at $69.99, and will be offered in two different colors.
