We’ve all been there (or at least some of us have). On top of a mountain, deep in the woods or by a spectacular waterfall. We want to take a selfie or ring our friends to boast about our achievements, only to find our phone is dead. Crisis! What do we do? We need to capture the moment. Relax. It’s not a problem, at least it isn’t if you have one of these handy Xenta solar chargers strapped to your backpack. Just plug your phone, or other compatible device, into the USB (Universal Serial Bus) port attached to the back of the panel & use the sun to recharge your battery. Simples.
