DWEII 3pcs Type-C 15W 3A Fast Charge UPS Power Supply / 18650 Lithium Battery Charger Module DC-DC Step Up Booster Converter 5V 9V 12V （5V）

Equipped with dual color LED to indicate the charging state, the green light is always on when it is fully charged, and the charging stops automatically.
The module is equipped with two 18650 battery sockets, a universal Micro USB charging port, and direct DC5V input to charge the lithium battery.
Boost circuit: peak power up to 20W, rated power up to 15W,BOST boost circuit, built-in 12A high current MOS, efficiency up to 96%, module static power consumption 25mA, optional 5V/9V/12V output. (Load normal recommendation <15W. Output 5V: Current 3A ；Output 9V: Current 1.6A ； Output 12V: Current 1.2A)
UPS function: When the power supply is powered, the power supply directly supplies power to the load through the boost circuit, and at the same time charges the lithium battery. 1 the power is cut off, the battery path is automatically started to supply power to the load via the boost circuit.
The 5V charging power supply used by individual users uses an output capacitor with a larger capacitance value. This capacitor can continue to discharge after the power supply is powered off, so that the power supply voltage has a slow down process, which will cause the board to not switch battery power supply quickly after the power supply is turned off. If you encounter such a situation, you can connect a discharge resistor of about 1K at the 5V input port.
