If plants thrive, why not technology? That is, converting sunlight into energy. The Ginkgo solar charger, which was "raised" by XD Design and which addresses the growing need for charging mobile devices and green politics, was inspired by them or solar cells. The idea for the design grew from the tall, lanky, sparsely branched and long-lived ginkgo tree, which Charles Darwin called a living fossil. With the difference that this Ginkgo has a built-in lithium battery with a capacity of 4000 mAh.
