For better charging, please replace the solar panel in somewhere more full sun, if it still does not work, please use your original cable or a third-party certified one to charge. ● The charging speed did not meet my expectation. The solar charging speed totally depends on the sun, cloudy weather, indirect sun may be too weak to power, please replace the solar panel in somewhere more full sun.
