Same with Android, the various fast charging protocols use the data pins to negotiate the voltage setting and how much current the phone is allowed to draw. I suppose in theory you could make an active dongle which MITMs the data pins and strips anything it doesn't recognise as a valid fast charging command, but I don't know if such a product exists.
