Features:
This product is suitable for the application of power failure equipment without power failure. When power is available, external power supply is used. When power failure occurs, it will automatically and seamlessly switch to battery power supply.
The Type-c interface provides power. Compared with the microUSB interface, the current that can be passed is much larger, and the maximum current can be 5A.
It is suitable for routers, cameras, development boards and other equipment. It can switch the battery power supply seamlessly when the power is off, and the power supply is continuous
Seamless switching of external power supply and battery two-way power supply (without delay). Uninterrupted power supply, self-starting after power failure, self-charging after power call.
Output voltage 5V/9V/12V can be selected,
Lithium battery charging, lithium battery protection, boost output and UPS switching.
The two-color LED indicates the charging status, and the green light is always on when it is full, and the charging will stop automatically.
Type-C interface, high current.

Interface: Type-c interface
Peak power: up to 20W
Rated power: up to 15W
Module size: 88 * 41 * 22mm length, width and height (back patch box)
Product Instructions:
1. USB port and standard 5V+and 5V - are external power supply ports. You can choose one of them. The output interfaces are marked with USP+and UPS -. The back welding battery box is connected with 18650 lithium battery. It can also be connected to other 3.7V lithium batteries.
2. When used as a UPS, it is necessary to install the battery to ensure that the input 5V power supply has sufficient power, and the output is kept on in real time. When the power supply is cut off, the battery can be started at any time.
3. If UPS wants to save energy consumption, weld the output indicator light after all tests are completed, which can reduce the current consumption of more than 10 mA without affecting the normal output of the circuit and save power.
4. During operation, it is possible to trigger the board to enter the protection state without output due to various reasons (wrong touch, wrong connection, etc.). You can connect a 5V charging port to the board after the problem is solved, and the board can be activated and output again after it is powered on again.
5. The 5V charging power supply used by individual users uses an output capacitor with a larger capacity value. This capacitor can continue to discharge after the power supply is powered off, making the power supply voltage have a slow decline process, which will cause the board to not switch the 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.
6. If you want to increase the battery capacity of the UPS module, you can use the method of multi-section parallel connection, and other functions will not be affected.
