Superior Portability Design: Small and portable design with a same size as an iPhone 6, easy to hold in hand and hang on backpack. Perfect for hiking, climbing, camping and other outdoor activity. The efficiency of energy transformation from solar to electric energy is really low, even in a perfect laboratory condition, the transformation efficiency just 30%. When it used in outdoor, it also affected by the weather, the location or others factors. So the solar panel is not good as first choose to recharging. We suggest you recharge it via wall charger, the solar pane only for emergency.
