QC2.0 to PD fast charge protocol (normal QC head and second
change PD charge iPhone X):
Ok key:
Short press: select power
adjustment, exit
m key:
-: Power broadcast reduced
by 1w
+: Power broadcast increased
by 1w
Exit Confirm execution (long
press to exit)
This function is to convert the ordinary qc charging head
and qc mobile power to convert the residual heat into the
pd protocol output. You must follow the steps below:
1. Connect u2 and qc charging head first 2. Connect pd power
equipment with cc line
U2 when entering the qc->pd menu
Only detect whether the charging head supports qc, do
not detect the charging head output voltage range, so u2
default pdo broadcast is
5v~20v pdo (automatically adjust pdo output)
When the charging head does not support qc20v, and the powered
device actively applies for 20v
At this time u2 will detect if the voltage has 20v, if the qc charger
does not have 20v gear
Pdo automatically cancels the 20v gear position, and the pd power
device will automatically apply for the low-end pdo voltage gear
position.
Power setting:
Since most of the qc2.0 3.0 charging head and charging
treasure qc output power generally does not exceed 24w
24w/12v=2a,
24W/20V=1.2A
Therefore, u2 provides power setting function. After
