USB-C interface that seems to look exactly the same, chargers may differ.
On September 25, #measured Apple can not use Huawei charger # rushed on the hot search, Apple iPhone 15 series officially went on sale on September 22, the whole series of Lightning interface changed to support USB-C port, some netizens got the new machine after testing and found that the charger of Huawei USB-A port in hand can not charge the Apple phone, and other domestic brand chargers such as Xiaomi or OPPO have no problem.
Some analysts pointed out that this is because some of Huawei's chargers and charging cables do not support the Power Delivery (PD) fast charging protocol, and only chargers and C to C cables that support PD protocol can charge the iPhone 15 series. Previously, according to surging news, Apple's iPhone 15 series supports PD protocol, so lines that support PD protocol can charge and transmit data for it.
The surging news reporter asked the official customer service of Apple and Huawei on this matter, and both sides said that it is recommended to use original charging equipment to charge mobile phones, because chargers with different charging specifications will damage battery life and bring potential safety hazards. When asked whether the situation of not charging or charging slowly is related to the PD agreement, Apple said that the current official for the agreement is not clear, or it is recommended to use the original, Huawei also said to see the charging specifications of Apple equipment.
Subsequently, the reporter consulted the customer service of Taobao Apple's official flagship store with the same problem, and the customer service said that the inability to charge was indeed because the PD protocol was not supported, and the third-party data cable could not guarantee charging, which may also cause problems with the device.
The reporter checked Huawei's official website and found that Huawei now has several high-speed data lines and fast charging chargers that support the PD 3.0 protocol, and will be marked on the sales page.

Also, although USB-C is a universal standard in theory, it is not. Although the physical appearance specifications are the same, the data and power transfer speed of each USB-C interface may be different, and some interfaces even transmit only power without transmitting data.
At present, on Apple's official website, the price of the 20-watt USB-C power adapter is 149 yuan, and the price of the 60-watt USB-C charging cable (1 meter) is 145 yuan.
For the original charging equipment of the iPhone 15 series, the charging power of the iPhone 15 Pro series is 25 watts, and the charging power of the iPhone 15/Plus is 20 watts. In terms of data transfer, since the iPhone 15/Plus only supports USB 2.0, the data transfer speed is up to 480Mbps, while the iPhone 15 Pro/Pro Max supports USB 3.0, and the data transfer speed can reach up to 10Gbps.
