The Lenovo 800 Self-Charging Bluetooth Keyboard generates electricity from everyday light thanks to photovoltaic technology, also known as solar cells.

It can turn ambient light energy and solar power into enough electricity for typical use.

Because there are no disposable batteries, the keyboard is better for the environment than batteries.

Lenovo also unveiled a pair of true wireless earbuds, a smartwatch-style wristband, a new ThinkBook laptop with a rollable display that turns into a portrait screen.
