"Handling for both and hinting" may be everyone's first impression of the Type-Ch interface, or it may be the only impression. It is undeniable that the Type-C interface is much higher than the Micro USB in terms of convenience of use, so we no longer have to worry about "can't plug in it anyway".
. The reason why this may be the only impression is that many users ignore or even understand another feature of the Type-C interface - "All in One". A fully functional Type-C interface, in addition to being blindly plugged in front and back, also supports functions such as high-speed data transmission, PD fast charging, and video output . However, these functions are likely to be castrated under the troubled waters of manufacturers.
We all call Type-Ch
The interface is castrated. We have to start with the "USB standard organization ", the developer of the Type-C standard. In order to end the dispute between data interface princes as soon as possible, the organization launched the USB Type-C interface (the full name of Type-C interface) in 2014. According to the organization's definition of it, as long as the interface shape and interface pins are the same as Type-C, the interface can be called Type-C interface .
At this time, Type-C is just a data/charging cable that can be plugged forward and reverse, and nothing else can be done. What makes the Type-C interface really powerful is the organization's subsequent " alternating mode (Alternate Mode)" which means that the Type-C interface can be used to replace other interface functions. For example, the DP and HDMI video interface on laptops are now being replaced by Type-C merger.
In addition to the video output function, the Type-C interface also supports data transmission up to 40Gbps and power transmission up to 100W.
We are really different
However, in order to implement the above functions, the Type-C interface needs to support the corresponding interface protocol (including data transmission, video output and PD fast charging). manufacturers can "customize the functions of Type-C" according to the given protocol, and castration also starts from this time.
Let’s talk about the data transmission part first. Children who understand the data transmission protocol may know that the current mainstream transmission protocols include USB2.0, USB3.0, USB3.1 (Gen1, Gen2), and Thunderbolt3 ( Thunderbolt3) that will appear on mid-to-high-end notebooks. The transmission rates of these protocols are incremented in turn. and Type-C interfaces are all-in-one. They not only support Thunderbolt 3 with a speed of 40Gbps (5GB/s), but are also compatible with USB2.0 with a speed of 480Mbps (60MB/s). The two speeds are more than 80 times different. The current mobile phone Type-C interface of currently supports up to USB3.1 Gen1, but the gap compared with USB2.0 is still visible to the naked eye.
Next, let’s talk about the video output part. Video output is an additional function of the Type-C interface on the basis of data transmission (i.e. the Altermate Mode part mentioned above). Like the transmission protocol, video output functions are also optional. Manufacturers can choose to equip the Type-C interface with DP1.2 or DP1.4 functions, or they can choose not to support video output. Among the mobile phones released in the past two years, only a very small number of mid-to-high-end models support this function (I didn’t see this function demonstration or introduction at the press conference, and there is a high probability that there will be no) .
finally comes with the PD fast charging part. This part of the protocol was actually born based on Type-C. It is not an exaggeration to say that it is "Moment, which is exclusive to the Type-C interface." According to the design, the maximum power support for PD fast charging is: 18W, 30W, 45W, 60W, etc. or even 100W. Compared with the castration strength of data transmission and video output, manufacturers are quite gentle in PD fast charging. Most brands have models that support PD fast charging. As for the power, it depends on the manufacturer's technology and conscience (of course, there are also that uses its own protocol).
tells me how to know if it has been castrated
If you want to know whether the Type-C interface of your mobile phone or laptop is full-function, the method is very simple. We can directly go to the product official website to view the parameters of the data interface part. If the interface supports "advanced" functions such as high-speed transmission, video output, and PD fast charging, manufacturers generally will not miss the opportunity to "Show Off" on the details page.
If it is not marked, don’t give up. Try to recharge and pass on a few small movies. Maybe you will find the small easter eggs prepared by the manufacturer (this article is not responsible for any easter eggs for the manufacturer). If you find that your Type-C interface can only be plugged in front and back, charging normally, and transmit data quickly, then "collection" this article and take it out and flip it out next time you buy a mobile phone.
castration does not mean that it is difficult to use
This is also castration, and then castration. Will the conscience of the manufacturer hurt? Most likely not.
We will take it for granted that castration of some Type-C interface functions is a cost-saving approach for manufacturers (it can indeed save costs), but from the user's perspective, this kind of castration is not incomprehensible.
Just imagine that in addition to charging your mobile phone frequently, the interface will be used to charge it (some users are even used to wireless charging), most of us use WiFi or mobile networks to complete the video output and data transmission parts. There are not many trigger scenarios for connecting and copying with data cables. If the saved costs are used to improve network transmission and wireless charging efficiency, isn’t this a more efficient and wireless connection solution? In fact, many manufacturers have invested a lot of energy in this regard.
Compared to wired, who doesn’t want the real wireless and fully wireless experience to come soon?
