ENDLESS energy, Endless Convenience

Exeger creates and produces Powerfoyle, a customizable solar cell that can be integrated into electronics to provide a sustainable alternative to traditionally charged devices. Using any available light – from natural outdoor light to ambient indoor light – it continuously powers devices to offer endless, sustainable energy.

Studies show that sustainability is an increasingly important factor for both young and old consumers as they consider electronic device purchases, and ease of use is the second most important decision-making factor globally. (Source: YouGov Consumer Electronics: Safety and Sustainability in 2023 report). With Powerfoyle-powered e-readers and e-notes, charging takes place naturally and continuously, so consumers’ devices are always ready to go.

So why not read one more chapter, start the next book or take one more note? When your device is always charged, there’s nothing to stop you. The story can continue.
