Among the many laptops and desktops that Lenovo announced at CES 2025 is an intriguing peripheral: the Self-Charging Bluetooth Keyboard. This unique productivity keyboard ditches the traditional battery, instead utilizing solar and ambient light to charge and store energy.
The Lenovo Self-Charging Bluetooth Keyboard might seem like your run-of-the-mill keyboard, but it comes with a party trick that might just save you a buck in the long run. Using advanced photovoltaic technology and fast-charging supercapacitors, the keyboard actually harnesses ambient light to store energy, eliminating the need for disposable batteries.
Reminds me of the at least 40 year old calculator my mother is still using, even though you need essentially a search light both for it to power on and to make out anything on the dim LCD screen. It’s always been like this though.
