Abstract: An adaptive charging system comprises at least one solar panel and a voltage regulator. The solar panel comprises a protective layer, a first EVA layer, a plurality of solar cells, a plurality of connectors, a second EVA layer and a first supporting layer. The plurality of solar cells are interconnected by the connectors, forming a main body layer. The protective layer, the first EVA layer, the main body layer, the second EVA layer and the first supporting layer are bonded together from top to bottom. The voltage regulator comprises a sampling logic power supply circuit, a microcontroller (MCU) logic circuit, a DC-DC charging circuit, a sampling current conditioning circuit, and a charging matching circuit. When the charging system charges Apple® devices, an automatic reset control logic can be implemented. The system detects the amount of light is changing based on the sampled voltage and the analog voltage signal, and monitors the detection for an additional duration of time.
