Information

1. Each brand, Huawei, Xiaomi, oppo, etc., promotes its own unique fast charging method. In the end, it can be said that there are only two fast charging methods: PD and QC. And, QC can also be said to be a branch of PD. A charger that supports PD can charge a mobile phone that supports QC, while a charger that supports QC cannot charge a mobile phone that supports PD.

2. The charging stage of fast charging can be divided into constant current precharging (small current), constant current fast charging (large current), and constant voltage charging (the current changes from large to small until the charging is completed), whether it is high voltage or low current (QC belongs to Such) or low voltage and high current, it is necessary to adjust the input voltage of the power adapter through the USB-C interface.
