[0029] In embodiment 3, the fixed circuit board 402 can also be set as the circuit board of the charging control module. Only the power output socket 303 is attached to the back of the photovoltaic battery 301. The chip 302, other electronic components 304, USB output interface 403, LED indicator 404, and TYPE-C output interface 405 are all soldered to the fixed circuit board 402. The power input plug and the power output socket 303 of the fixed circuit board 402 are plugged in.

[0030] like Figure 5 As shown, the solar-powered battery 301 converts light energy into electrical energy, which is first filtered by high and low frequencies through C1 and C4, and then passed through a voltage regulator circuit consisting of chip 302 (U1), resistors R1, R2, R3, R4, capacitors C5 and C6, and inductor L1 to a 5V output.
