Due to the increasing pressures of modern life

individuals are increasingly drawn towards reconnecting with nature through activities such as outdoor exploration

camping

and mountain climbing. However

certain remote locations may pose challenges in accessing traditional power sources. To address this issue

an intelligent outdoor small solar charging system is proposed. This system efficiently harnesses sunlight through solar panels

converting it into electricity and storing it in lithium batteries. The charging input of the system utilizes dual power supply options: solar panels and DC power supply. Additionally

a charge management module is employed for battery charging purposes. By effectively converting solar energy into electric energy and storing it within the system's batteries

reliable power can be supplied even in remote areas. Furthermore

the design incorporates visual indicators displaying information on lithium battery status and charging progress—enhancing its commercial value.
