Tested my ZY1276 for the above options….
- “Auto-detect” will try to detect (request) and list the protocols supported by the charger/powerbank
- “QC2.0” (assuming the charger supports QC2) will list the QC2 voltages 5/9/12/20v and allow you to select that output voltage (only for the voltages that the charger supports)
- “QC3.0” (assuming the charger supports QC3) will list the QC3 voltages 5/9/12/20v and allow you to increase/decrease the output voltage by 0.2v each time (again depends on what voltages are supported by the charger)
- “Huawei FCP” - when I tested this on a charger that lists this protocol, it selects 9v output
- “Apple 2.4A” - I tried selecting ths, but I’m not sure what happened, the screen just refreshed, and I’m not sure if it set to the Apple 2.4A mode or did anything… (the charger I tried supports Apple 2.4A protocol by default)
