Apple's phones since the iPhone 8 have supported fast charging. The iPhone XR is a mobile phone released by Apple in 2018, and of course it supports fast charging. Fast charging only requires a PD fast charging head (USB-C interface) and a USB-C to Lighting MFI certified fast charging cable.
Using 18W power charging, the charging speed is about 50% in half an hour and 80% in an hour. Full 1 hour and 20 minutes less. The speed is very fast, but the cost will be higher, suitable for students who pursue the ultimate fast charge. The use of PD fast charge requires a fast charge head and a C to L data line, which is also the reason for the high cost.
Fast charge must be charging head and charging line support fast charge to achieve fast charge oh!
