7 USB Quick Charge Port
The output voltage of USB quick charge ranges from
5V to 12V, providing a maximum output power of 18
W. The USB quick charge automatically adjusts the
output voltage and currentaccording to the identified
quick charge protocol. Typical output voltagesand
When charging an electronic device that does not
have quick charging function, charging will be
provided at standard 5V.
USB quick charge provides input overvoltage and
undervoltage protection, output overcurrent,
overvoltage, undervoltage, short circuit protection
and other functions.
The quick charge indicator lights up when the quick
charge request voltage is not 5V, that is, it lights up
when the request voltage is higher or lower than 5V.
