In one of my latest project, I recorded on ISD1820 with online text2speech service. I am impressed with the sound quality.
Some USB cables are Power only ( Vbus and Gnd ), those cables will no work with QC protocol.
When QC supported mobile device is connected to any Adapter/Power Bank, it will send voltage signals through the D+/- of the USB cable depending on the state of charge of the battery. If the Adapter/Power Bank also supports QC, then Output voltage from those power source will be adjusted accordingly.
Read the "Device Operation" section above to understand the mechanism.
For QC to work you need 3 things
1. QC supported mobile device
2. QC supported Supply (Adapter/Powerbank)
3. USB 2/3 Data cable ( at least 4 wires Vbus, D+,D-, Gnd )
QC is one way communication requested from device side to power supply side, as far as I know you can't chose/select it manually for mobile devices.
