A:AnswerIf you get the USBC one it is compatible, but if you get the lightning one it will not work because the lightning cord will not fit in you iPhone 15 charging port. The lightning version is also $50 less because the older iPhones are the ones that take the lightning cord and the 14-16 iPhones all have the new ports. Hope that answers the question!
