What is the difference between a double type-c data cable and an ordinary data cable?

Both ends of the dual Type-C data cable are Type-C interfaces

The general Type-C data cable has a Type-A male head at one end and a Type-C male head at the other end. Both ends of the dual Type-C data cable are Type-C male.

What is Type-C?

Type-C is the latest USB interface. The launch of the Type-C interface perfectly solves the inconsistency of the physical interface specifications of the USB interface and solves the defect that the USB interface can only transmit power in one direction. Integrates the functions of charging, display and data transmission. The biggest feature of the Type-C interface is that it can be plugged in both forward and reverse, and it does not have the directionality of the Type-A and Type-B interfaces.

The Type-C interface adds more pin lines. The Type-C interface has 4 pairs of TX/RX differential lines, 2 pairs of USBD+/D-, a pair of SBUs, 2 CCs, and 4 VBUS and 4 a ground wire. It is symmetrical, so there is no wrong way to insert it forward or backward. Due to the addition of more communication control pins, the data transmission speed of USB is greatly improved. With the blessing of communication protocol, it is easy to realize fast charging of mobile devices.

What is the function of the dual Type-C port data cable?

The standard Type-C port has no power output in the standby state, and it will detect whether the plugged-in device is a device that provides power or a device that needs to obtain power. For the data cable with a single Type-C port, the other is a Type-A male head, when the Type-A male head is inserted into the charging head. It will provide power, so the Type-C port on the other end can only accept power. Of course, data can still be transmitted in both directions.

The dual Type-C port data cable is different. Both ends can receive power. If the dual Type-C port data cable is plugged into two mobile phones, since the Type-C port has no power output in the standby state, the two mobile phones have no power output. Response, no one charges anyone, only after one of the mobile phones turns on the power supply, the other mobile phone can receive power.

Using the dual Type-C port data cable, we can charge the power bank to the mobile phone, or vice versa, use the mobile phone to charge the power bank. If your phone runs out of battery, you can borrow someone else’s phone to charge it.
