  Support fast charge protocol:   Qualcomm QC 2.0 /QC 3.0 DCP (Apple Apple, for Samsung and BC 1.2 ) MTK PE 1.1 /PE 2.0 Fast Charge
Protocol FCP/SCP Applications:   Mobile power, charging treasure Portable devices such as mobile phones and tablets
Precautions:   Low power lock and activation: when the module is connected to the battery for the first time, regardless of the battery voltage, the chip is in the locked state, the lowest position of the power lamp will flash 4 times to prompt; in the non-charge state, if the battery voltage too low triggers a low power shutdown and it also enters a locked state. In the locked state, in order to reduce the static power consumption, it has no mobile phone insertion detection function and cannot be activated by pressing a button. At this time, the button action cannot activate the boost output, but the lowest level of the power lamp will flash 4 times to prompt. In the locked state, it is necessary to enter the charging state to activate the chip function.
  Package includes:   1 x  JHE-QC23S  USB port fast charging module 1 x  MICRO USB Adapter Board
