can not
The 66W Super Fast charging head cannot be used to charge the iPhone 8 Plus, because the phone was launched in 2016, which is an older model, and the battery was not designed for fast charging mode at that time, so it cannot withstand the 66W high-speed charging power. For other models of iPhone, even if you can use 66W fast charge, its charging speed can not reach the level of 66W, because Apple officially supports the maximum charging power of 20W
