Question：how often does this have to be recharged manually ? can i rely on sun only? Answer：The battery capacity is 3350mah, which can continuously work for 7.5 hours on a full charge. If you use the product 3-4 times a day, it will work for 45-60 days. The solar panel can be used as a tool to supply power to the battery, extend the working time of the backup camera and reduce the charging times. however, solar charging cannot completely replace USB charging, especially when the battery is low. https://drive.google.com/file/d/1PcgZum9-5vhp0TEfJtCK9qev7ofGa4ux/view?usp=sharing">SOLAR 1 PRO Manual download
