Note: Even in a perfect laboratory condition, The efficiency of energy transformation from solar to electric energy is really low. When it is used outdoor, it is also affected by the weather, the location, or other factors. So the solar panel is not good as the first choice for recharging. We suggest you recharge it via a wall charger at the beginning to make the power battery fully activated. Packing included:1 x Power Bank
