Again, neither would be "better" than the other for this iPhone. Both would work equally well. It helps to understand that these Apple power adapter are "smart." That is, both of them are designed to know when to adjust the charging level based on the phone's battery condition. Neither would charge your phone any faster. If given the choice, I would pick the 18W adapter for the iPhone.
