Features 1、Fast Charging: The charging process is divided into the following three processes, trickle mode, constant current mode and constant voltage mode. When the charging current decreases to the cut off current, the charging ends. After fully charged, if the battery voltage drops to 0.1V lower than the target voltage, it will automatically restart charging. 2、Trickle Mode: When the battery voltage is lower than 3V, the charging module is in trickle mode, and the charging current is 300mA. 3、Constant Current Mode: When the battery voltage is greater than 3V, the charging module will enter the constant current mode. At this time, it will charge at full speed according to the set target current, and the power can get up to about 21W. 4、Constant Voltage Mode: When the battery voltage rises to the charging target voltage, such as 4.2V, the charging module enters the constant voltage mode, the current gradually decreases, and the battery terminal voltage remains unchanged. 5、Supporting Protocol: Supports PPS, PD3.0, PD2.0, QC4+, QC4, QC3.0, QC2.0, AFC, PE2.0, PE1.1, SFCP, vooC, input fast charge protocol support for PD3.0 PD2.0, for FCP, SCP. 6、Wide Application: Supports 4.2V, 4.35V, 4.4V, 4.5V battery type, current up to 5A, efficiency up to 95%, support JEITA specification, support temperature loop control, Type C interface, supports Try.SRC function.
