The iPhone 15 Pro uses a Lightning charging port, while the Huawei charging cable is a Type-C port. Although both are USB ports, they are not compatible. Therefore, you cannot charge the iPhone 15 Pro directly using the Huawei charging cable. If you need to charge the iPhone 15 Pro, it is recommended to use the original Lightning charging cable or another charging cable that works with the Lightning port. Using incompatible charging cables can cause problems such as unstable charging, slow charging and even damage to the battery.
