Problems solved by technology

[0002] In real life, with the rapid development of science and technology, people's living standards are also improving day by day. They often need to carry a variety of electronic products to go out to work or travel. There are also a variety of spare batteries. When the power is exhausted, each battery needs to be charged. This is not easy to manage and carry, and it is troublesome to charge. The existing mobile power supply has a single function and is inconvenient to use. A more functional power supply circuit is needed to solve this problem.

Embodiment Construction

[0015] Such as figure 1 As shown, a mobile power supply circuit includes a lithium battery charging circuit, a solar charging circuit, a lighting circuit, a switch control circuit, a charging circuit and a power prompt circuit;

[0016] The lithium-ion charging circuit is connected to pin 4 of the lithium battery charging management chip U1 through the miniUSBJ1 through the filter capacitor C19, and then leads from the pin 4 to the resistor R1 to the light-emitting diode D1 to pin 1 of the chip U1. Pin 2 is grounded, pin 3 of chip U1 is connected to the positive pole of lithium battery J3 through filter capacitor C2, and pin 5 is grounded through resistor R2;

[0017] The solar charging circuit is that the output of the solar panel is connected to the positive pole of the lithium battery J3 through the rectifier diode D2;

[0018] The lighting circuit is that pin 1 and pin 11 of the chip U2 are connected to connect a resistor R4 to the ground through a capacitor C4, pin 4 of ...
