Quick Charge 2.0 Powerbank Adapter Board

Veröffentlicht von brun am

A small adapter board which emulates a Quickcharge 2.0 (also compatible with Quick Charge 3.0) capable device to force a power supply or a powerbank to output higher voltages.

Quick Charge 2.0 specification

The output Voltage can be configured by applying different voltage levels to the USB data lines D+ and D-:

With this board these Voltage levels are set by different jumper settings.

Please note that due to the Quick Charge specification the jumper settings have to be done AFTER inserting the adapter into the power supply or powerbank. After plugging in the adapter, the powerbank will output 5V no matter how the jumpers are set. Higher voltage outputs can only be achieved by changing the jumper settings after inserting.

Voltage Levels:

D+D-output voltageJumper positions:J1J2
0,6V0,0V5V (default)x
3,3V0,6V9Vx
0,6V0,6V12Vxx

Jumper positions: x = set, blank = not set
