Meet the QBAND: an interesting solar charger that you can wear like a watch. It is designed to charge your smartphone on the go. It has a 600 mAh Li-ion battery and a 500mW solar array. You also get a flexible band and a LED watch face. The watch has micro USB or Lightning connectors, allowing you to connect it to your phone without having to carry a cable around.
The QBAND is compatible with iOS and Android devices. We can’t say how well it works since we have not tested it, but the idea looks interesting. The problem is we have seen similar ideas in the past. They look great on paper but never work as promised. This interesting thread on Reddit covers more questions on the project.
