One of the coolest parts of CES is getting to preview the future of technology. LG’s iRobot-like helper robot and Sony’s XYN headset are two such examples from last year’s event. Those are rather large and ambitious tech projects, but Lenovo is tackling a different sort of problem with its Self-Charging Kit Concept, which consists of a solar-powered mouse and keyboard that can charge themselves without natural sunlight
Lenovo says this technology provides “one of the industry’s first true no-charging” experiences.

The tech uses what Lenovo calls “next-level light-harvesting technology,” which charges the mouse and keyboard using indoor light as low as 50 lux. For reference, most grocery stores are somewhere between 200 and 500 lux, so 50 lux would be equivalent to an overcast day, give or take.
These days, virtually every device comes with a throwaway USB-C charging cable, and we love the idea of having a truly wireless gadget with no charging required. Based on product images, it appears that the charging panel is right above the arrow keys on the keyboard and integrated into the mouse’s entire top side.

Lenovo was a little vague in terms of other features, but based on the concept images, there are three Bluetooth buttons, indicating that the kit will be able to connect to multiple devices with the push of a button, and an eco mode button that will likely reduce functionality to help the battery last longer.

Lenovo gets points for having such a neat concept, especially one that can charge in such low light. This concept already exists in some products, such as this Logitech solar-powered keyboard, which can hold its charge for up to three months in total darkness. However, Logitech’s documentation says that keyboard needs at least 100 lux to charge, so Lenovo’s concept not only has a cleaner design, but also works in much dimmer lighting.
Since this is a concept product, there is no release date or price tag. For comparison’s sake, Logitech’s previous solar model sells for $300 when not on sale.
Lenovo has debuted a ton of new concept products and AI laptops for CES 2026, and Mashable got the chance to spend some hands-on time with the products. Check our CES 2026 hub for the latest news and updates as Mashable reports live from the biggest show in tech.
