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.
I used to have a Logitech K750 solar keyboard. The battery was always dying. The only difference from a traditional charging keyboard is instead of a charging cable, I had a charging desk lamp.
I have a K750, the battery is about 15 years old with daily use. The original battery was dead when I opened it, I just bought one when it was new, and it’s still going.
In another thread some days ago others shared similar experiences as you, so maybe I’m the lucky one.
I live in a bright flat, and my computer was always near to the window, it’s charge never went below 80-90%, so maybe that’s the reason for its longevity.
hahaha, that’s a solution!
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.
