Agreed. The 9v2 Mi charger can be used as an iPhone 11. At present, there are basically only a few companies that provide fast charging solutions. The high voltage fast Charge scheme (improve voltage to improve charging efficiency) is provided by Qualcomm Quick Charge 3.0\/2.0 and Mediatek Pump Express Plus, as well as OPPO VOOC flash charge (low voltage and high current). Huawei's fast charge technology is also a low voltage and high current scheme.
Of course, it supports the current charger, since he has written the specifications, he is that it will automatically detect the most consistent charge.
