The Window Socket by designers Kyuho Song and Boa Oh.
As seen from Yanko Design article. This highly portable solar power device could change the game of clean energy! It takes 5-8 hours to complete charging but that charge lasts 10 hours. The article says that it produces 1000 mAh--unfortunately I don't know enough about electricity to explain what this means. Could anyone explain in comments for clarity?
(Thanks Dragonfly for the heads up!)
