The answer is as follows: Not all brands of fast charge technology are compatible. At present, there are many fast Charge standards in the market, such as Qualcomm's Quick Charge, Huawei's SuperCharge, OPPO's VOOC and so on. Different brands often use their own fast charging technology, so different brands of fast charging appliances and devices may not be compatible with each other.
However, some brands are also starting to adopt common fast charge standards, such as USB Power Delivery (USB PD), so that compatibility between different brands of devices can be achieved.
Indeed, because the fast charging agreements of various brands are not the same, the fast charging is not compatible, that is to say, you take the charging head and data cable that support the fast charging of other brands to charge another brand of mobile phones often cannot achieve the fast charging effect.
