Physical Interface Innovation

The USB-C to USB-C charging cable included with the iPhone 15 Pro Max features a 24-pin design, supporting reversible plugging, completely resolving the pain point of the Lightning interface’s single-sided insertion. Test results show that the cable’s insertion/removal lifespan exceeds 10,000 cycles, a 40% improvement over the Lightning interface. The interface terminals use gold-plating technology, with oxidation resistance improved by 3 times compared to the previous generation, and the contact resistance change rate remains below 5% after long-term use.

Protocol Compatibility Breakthrough

This charging cable supports the USB PD 3.0 protocol, capable of delivering up to 25W of power output. According to tests conducted using the POWER-Z KM003C tester, when paired with an Apple 30W charger, the cable negotiates a voltage level of 9V/2.95A, achieving an output power of 24.93W—a deviation of just 0.3% from the officially claimed 25W peak power. Additionally, the cable is compatible with third-party fast charging protocols such as QC 4.0 and PPS, enabling 18W fast charging on non-Apple devices.

Data Transfer Upgrade

Thanks to the USB 3.0 specification, the cable’s theoretical transfer rate reaches 10Gbps. In real-world testing, when connected to an iPhone 15 Pro Max using a SanDisk Extreme Pro SSD, 4K video import speeds reached 780MB/s, a 16-fold increase over the USB 2.0 (480Mbps) interface of the Lightning connector. For professional photographers, this means 20GB of RAW footage can be transferred in just one minute.
