Product selling point:
1. When the load current is less than 50mA continuously, the output will be turned off.
2. Support external keys, connect the keys to the K point and the output negative electrode, short press to turn on the power display and turn on the 5V output, and short press twice in a row will turn off the power display and turn off the 5V output.
3. When the charging current drops to 100mA after reaching the final floating charge voltage, the charging cycle will be automatically terminated.
4. When the battery voltage is lower than 2.8V, the battery will be precharged with a current of 180mA.
5. The welding position of USB-A mother seat is provided on the back of the product, and the mother seat can be installed manually.
6. Support charging and discharging.
7. When the battery voltage drops below 4.1V, the charging cycle starts again.
