OS – a Japanese company that makes retractable screens for projectors – has invented this very handy portable solar power-on-the-go device, that sells for ¥60,000 - or about $730.
The GSR-110B solar generator uses flexible solar cells developed by Fuji Electric Systems, and it is a mini solar setup that is completely off-grid, since it includes its own small rechargeable battery right in the case.
The GSR-110b weight 3 kg (6.6 pounds)
