Does type-C cable really support mixed front and back insertion?

First of all, the conclusion is supported.

No matter what you buy in the market is pure charging cable or data cable, it supports double-sided hybrid plug-in

No matter what you buy is a to C or C to C, it can be mixed on both sides

I'd like to remind you that you don't have to worry too much about whether you can mix the front and the back. When you learn more about different type-C data cables, there are a lot of high-definition graphics below, which are used as extension of type-c.

So why not support it?

Of course, it's the title party. I can play less than 2000 videos in one hour, but I can get a title, which is more than 8000 +

So the question is, do you want to play the title party in the future videos of the main road, or do you want to have an honest and common name?

I can slip the title party, just very restrained, ha ha ha!!!

This video really shows you:

Blind insertion has a certain probability of no response (no power on)


So why?

Of course, it's the detector in my hand

It doesn't matter if you buy a niche brand like Phoenix, or chargerlab power-z, or yzx studio.

There will be similar situations. Why?

Because this machine is often used as a middleman agent, there is a concatenation!!!

Concatenation is a factor

The type-C interface design is also a factor

The following figure shows the pin diagram of type-C:

Whether you are a full-function type-C cable or a half function or a lightning 3 cable, the pin is the same.

Some pins are omitted according to different requirements

For example, if we only need the power supply function, generally only the following pins are welded:

The male port only needs 5 pins on one side to charge

In the picture above, two colors are used to mark the main road. Only one side of many charging wires is soldered with pins (5pin extremely shrunk version).

Because one side is enough

Only GND / VBUS / CC is needed for power supply

VBUS positive, GND negative, and CC is used for communication

The 24 needles contained two CC, CC1 and CC2

But communication can only be CC1 and CC1, CC2 and CC2

CC1 and CC2 will be disconnected, and CC2 and CC1 will be disconnected

In order to ensure charging or interactive data can be mixed

The charging head (female port) has two sides of CC1 and CC2

There are CC1 and CC2 in the mother port of notebook or mobile phone

So when the charger is connected to the laptop / mobile phone, you can plug it in any way you like!!

Either CC1 connection or CC2 connection can be guaranteed, which can be adaptive to realize charging and data transmission.

The same is true for laptops and laptops connected through type-C, and for laptops and mobile phones connected through type-c.

However, once the detector is connected in series in the middle, the CC1 and CC2 will be connected, so the power supply cannot be supplied.

Even two full pin type-C data cables

I've prepared five different data cables for you, as follows: let's enlarge the pins in the interface and show them in the order shown in the figure

Lvlian lightning 3 data cable supports 100W charging and 40Gbps data transmission

Lightning 3 must be (10 groups of symmetrical pins, a total of 20 pin) design, and there are six corresponding clasps at the edge. Good lines have this thing

Realme mobile phone charging line has no parameters, but it can be powered by 65 watts. The figure below shows 11 pin


This 11pin supports charging and data transmission

Draw a 11pin pin pin welding for you

There's only one CC1 or CC2, and there's D-and d-more+

Bess e-marker chip data cable supports 100 watt charging and 480mbps transmission speed

The data cable of e-marker chip is also 24pin, and it also has 6 snap rings. The difference between e-marker chip and lightning 3 is the speed

iPhone Charger Adapter

Anker charging cable, C to L, charging maximum about 60 watts, transmission 480mbps

Like the realme charging cable, the 11pin design

Purple rice charging cable, supporting 100 watt charging (including e-marker chip), non 24pin design

With the 14pin design, which is also CC1 and CC2, double D - and d-at the same time+

Only ①, ③ and ⑤ of the above five wires are suitable for testing. Two 24pins and one 14pin contain CC1 and CC2.

In order to ensure that there is no deviation in the test, we choose green Gan 65 w 3c1a as the charging head.

I think I have tested the data cable from 20 yuan to 200 yuan. There is no need to explain so much. It is a very simple truth.

The solution is simple.

The detector system can identify CC1 and CC2, and let them automatically pair, which can solve this problem.


OK, let's stop this problem. Ha ha.

So the question is, if you want to buy a C-to-C data cable to achieve 1GB / s transmission speed, which one should you buy?

The data cable of e-marker chip pulled out by Dalu is 480mbps, obviously not satisfied

Lula's thunder and lightning 3 data cable is too expensive, obviously generally do not want to start

Dalu tells you to buy a USB 3.1gen2 cable ✔, GEN1 (5Gbps) doesn't work

USB 3.1gen2 is the real 10Gbps data cable. This kind of data cable only supports 1GB / s file transfer or external display. Otherwise, do you think 480mbps can bring the display? 1080p doesn't work.

Just buy the one above. The 20 yuan cable can only be used for charging, and the file transfer speed is only 60MB / s.

To give you more choices, Beisi also meets the full function

The above is what I released on April 5, 2021

Thank you for your participation in the discussion and exchange. Since you are interested in this, I will continue to popularize some contents for you. Some contents refer to Wikipedia [1], and some contents are interpreted and analyzed according to the standard data.

First of all, type-C is a standard interface. To put it bluntly, it's called type-c. the following figure shows: but type-C has many protocols, such as common USB, which is the most basic and common. We know that the earliest USB is generally called 1.0, then 1.1, 2.0, and finally from 1.0 to 2.0 is divided into 2.0 [2] specification

You can find many interesting things from the past USB versions. For example, the speed of USB 1.0 is not as fast as the current Bluetooth transmission speed. Then USB 1.1 is called full speed, but USB 2.0 is called high speed. Let's see whether it is full speed or high speed???

iPhone 12 charger cable

This thing can drive us around, and then USB and wireless related, as well as the early high-power power supply.

It can be divided by speed

480mbps, USB 2.0

5Gbps, or USB 3.0, is now called USB 3.1gen1

10Gbps, or USB 3.1, is now called USB 3.1gen2

20gbps, enhanced version of USB 3.1, real USB 3.2, using Gen2 * 2 mode, speed doubled

40Gbps. This is not lightning 3, but USB 4


iPhone Charger Cable

At present, the media of USB4 seldom talk about this thing, and there are relatively few mature products.

Some netizens said that the data cable of lightning 3 is so expensive???

In fact, it used to be more expensive, because now it's much cheaper for thunderbolt 4 Intel to popularize. In fact, USB 4 is compatible with Intel's thunderbolt protocol. On the one hand, it's Intel's compromise, or to promote its products.
