LAS VEGAS -- Battery chargers are awesome and necessary, but only until they run out of battery. We've all been there, helplessly staring at a dead phone and a dead "back-up" battery charger. But what if said back-up charger was fueled by the sun?[#image: /photos/55ad7beab01eefe207f70b2d]|||waka-waka-518.jpg|||
WakaWaka Power+ ($79) is durable, lightweight solar charger that fully charges an iPhone 5s in just two hours. (It'll charge any device that connects to a USB.) So just connect it to your phone, hang it on your golf bag, and let it do its thing.
