Features Charging Process: The charging process is trickle mode, constant current mode and constant voltage mode, with simple operation and efficient charging. Applicable Battery: The fast charging module supports 4.2V 4.35V 4.4V 4.5V battery type, with current up to 5A and high efficiency up to 95%. Multiple Functions: The charging module supports JEITA specification, temperature ring control, with 5 USB interfaces to meet more requirements. Voltage Range: The input voltage is 6V-32V, the output voltage is 5V by default. After triggering fast charging, it will automatically adjust between 3-12V. Good Protection: With input overvoltage, output overcurrent, short circuit, charging timeout and temperature protection to ensure safe and reliable operation. Specification: Item Type: Fast Charging Module Material: PCB Input Voltage Range: 6V-32V Output Voltage: 5V by default. After triggering fast charging, it will automatically adjust between 3-12V Output Power: 22.5W( 5V at 3.4A, 9V at 2.5A, 12V at 2A) Conversion Efficiency: 95%. 1.
