At CES 2026, Lenovo plans to unveil the Lenovo Self-Charging Kit-a solar-powered keyboard and mouse capable of harnessing energy from any form of light. Even under the dim condition of just 50 lux, these peripherals efficiently gather power, setting a new standard for energy collection far below the requirements of ordinary solar panels.

In comparison, small solar panels commonly used in calculators need between 200 to 500 lux to function. The provided image depicts the keyboard and mouse kit, suggesting the implementation of solar cells atop the arrow keys.
Recent advancements indicate a significant boost in efficiency for solar-powered devices. As Paul Smith, a renowned expert in solar technology, highlights, “The integration of low-light solar collection into everyday devices like Lenovo’s kit represents a crucial step towards sustainable tech consumption.” Much of these advancements are attributed to new solar cell materials that convert light into electricity with unprecedented efficiency.
Such innovations may soon enable solar technology to largely power everyday electronics, reducing reliance on traditional electricity sources and paving the way for a more energy-independent future. Lenovo’s move marks an evolution not only in peripheral technology but also emphasizes a broader trend towards eco-friendly consumer electronics.
