Type-C, USB-C, universal C port, lightning C port, PD fast charge interface, DP port, how to distinguish?

Usb-c, the full name is USB Type-C, also known as Type-C port.

Since it is called Type-C, it means that there are Type-A and Type-B

Type-C is an interface specification that specifies which pins should be in a Type-C interface

See the difference?

Type-A has only 4 pins and can distinguish between ± power supply and ± data

Type-B is also 4 pins, but reduced in size (and not by much).

Later, USB 3.0 was added, with a group of pins in the middle.

But to Type-C, there are 12 groups, 24 pins (A1 and B1 are a group, the position is center symmetric, easy to insert forward and backward).

As for lightning mouth, all-purpose mouth, DP mouth, PD mouth, is there a possibility that the manufacturer simply castrated some stitches in order to save costs?

The so-called full function is that every stitch is used, no castration.

As to how to distinguish...

There's no need to differentiate. Just buy a full-featured cable.

Whether compatible with lightning is determined by the CPU, but also depends on the motherboard chipset to give function support, buy an AMD notebook, and then study is not support lightning 3.

Type-C is just a form, similar to this is a 500ml beaker, you use this beaker to really boil water, or fish, flowers, soy sauce vinegar, does not affect it is a beaker.
