Bsi 20w fast charge has Apple authorization, although the MFi certification is mainly for the data cable, but if the charger and the data cable are bundled together as a set to apply for MFi certification, Apple officials will strictly test the data cable and charger, that is to say, the MFi certified set, charger and data cable Apple will help you turn off. However, it is not to say that the charger is not good without certification, but it needs to be checked by itself.
