1, iPhone 8, iPhone 8Plus, iPhone X and all subsequent updated iPhone models support 18w fast charging;
2, as of June 2020, in addition to the two models of the iPhone 11Pro series, the remaining iPhone models that support fast charging need to purchase a charging head that supports the pd charging protocol and a type-c to lighting data cable separately, and can use 18W PD fast charging with the combination of the two;
3, the gap between fast charge and slow charge is particularly obvious in the 0-50% charging stage, taking iPhone XS Max as an example, it takes 90 minutes to use Apple's original 5W charger, while the 18W charger only takes 30 minutes.
