What is a defining characteristic of the Lightning cable?

The defining characteristic of the Lightning cable is that it is proprietary for Apple devices. This means that it is specifically designed and manufactured by Apple for use with its products, such as iPhones, iPads, and iPods. The proprietary nature of the Lightning connector ensures that it works seamlessly with Apple's ecosystem and supports features that are optimized for their devices, including audio and video output, fast data transfer, and compatibility with accessories designed for Apple products.

While the Lightning cable does support various data types like power delivery and audio, its uniqueness stems from being exclusive to Apple, differentiating it from other universal connectors like USB-C or Micro-USB that can be used across a broader range of devices from different manufacturers.

Understanding this characteristic is important for recognizing how Apple has structured its ecosystem and the implications for compatibility with accessories and other devices.
