- BigJ1211 7y agoFast charging depends on the compatibility with certain standards (USB-PD or Qualcomm Quickcharge). If it can't communicate that it resorts to the default, which is 5v/0.9A or 4.5W. So you would need compatible cables to make fast charging work, and then it will only fast charge up to 80% and then slow down. USB-PD is the standard for power delivery and Apple (and Google) both rely on that, so if it's USB-PD compatible it'll support the quickest charging it can handle.
