Some reports I searched show that solar charger has a slow charging speed and a low conversion rate of electric energy. The solar charging effect is not obvious, which is exactly what I feel after using. However, when there is an emergency when my phone and charger are out of power, I think the function must be a great help. In general, the product is light in weight and looks good in quality. It is convenient and suitable for camping. P.S. Do not put the charger in a high temperature environment, otherwise it may cause danger.
positive
