1. Main Control Chip: IP2312
2. Input Voltage: 4.5-5.5V
3. Charging Cut-off Voltage: 4.2V/4.35V
4. Charging Current: 3A
5. Indicator Lights: Red (Working), Green (Fully Charged)
6. Dimensions: 32x15x5mm
7. Weight: Approximately 3g
Charging Modes:
1. When the battery voltage is below 3V, it enters trickle charging mode, charging the battery with a 100mA charging current.
2. When the battery voltage is above 3V, it enters constant current charging mode, charging the battery with the set constant current.
3. When the battery voltage approaches 4.2V and the charging current is less than 300mA, it enters constant voltage charging mode. After entering constant voltage mode, charging stops every four minutes, and the battery voltage is checked to see if it is higher than 4.15V: if it is higher than 4.15V, charging stops; otherwise, charging continues, and the voltage is checked again after another 4 minutes.
4. After the battery is fully charged, if the battery voltage is detected to be below 4.1V, charging will resume.
