Technical Specifications Item Type: Battery Charging Module Input Voltage Range: 5 to 5.5V Charge Cutoff Voltage: (4.2V/4.35V) ± 0.5% Charge Current: 2.4A ± 5% Boost Output Voltage: 5V to 5.15V (charge loss compensation) Boost Output Voltage Ripple: 100mV Boost Output Current: 2A Boost Conversion Efficiency: 92.5% (3.6V input, 5V 2A output) Battery Quiescent Current: < 30µA Compatibility and Accessories 1 Battery Charging Module 1 USB Port Installation External Button Support: Connect the button to point K and the negative output terminal. A USB-A female connector is provided on the rear of the product and can be manually installed. Operation: Press briefly to turn on the display and activate the 5V output. Two consecutive short presses turn off the display and the 5V output. When the charging current drops to 100mA after reaching the final hold voltage, the charging cycle automatically stops. The charging cycle restarts when the battery voltage drops below 4.1V. When the battery voltage is below 2.8V, the battery is pre-charged with a current of 180mA. The output is disabled when the charging current is below 50mA. Other information
