At present, only the first and second generation iPad Pro 12.9 inch, iPad Pro 10.5 and iPhone8, iPhone8 Plus and iPhoneX support PD fast charge, and other models do not support PD fast charge. The machine does not have the fast charge function, after inserting the data cable, the fast charge function cannot be activated, and the charging effect will be maintained at a very low current, and the charging effect is not as good as the random charger.
