The highlights of the new version of the interface are slimmer design, faster transmission speed (10Gbps) and more powerful power transmission (100W). The most unique feature of the Type-C reversible pluggable interface is that it supports double-sided insertion of the USB interface, which officially solves the worldwide problem of "USB can never be plugged in correctly". You can plug in the front and back at will. At the same time, the USB data cable used with it must also be thinner and lighter.
So, why do the newly released mobile phone interfaces need to be replaced by this kind of interface? What is the unique charm of USB Type-C?
1. Technical features:
USB Type-C has the following features:
1. The data transmission speed reaches 10Gbit/s, which is also the standard of USB 3.1;
2. The size of the Type-C interface socket is approximately 8.3mm × 2.5mm slim design ;
3. Supports the "front and back insertion" function that can be inserted from both front and back sides, and can withstand 10,000 repeated insertion and removal times ;
4. The standard cable equipped with Type-C connector can pass 3A current, and also supports "USB PD" that exceeds the existing USB power supply capability and can provide up to 100W of power .
2. Appearance features:
1. Ultra-thin
A thinner body requires thinner ports, which is one of the reasons why Type-C was born. The Type-C port is 0.83 cm long and 0.26 cm wide. The old USB port, which is 1.4cm long and 0.65cm wide, already looks outdated. This also means that the end of the Type-C data cable will be one-third the size of the standard Micro USB-type data cable plug.
2. No pros and cons
Like Apple's Lightning interface, the Type-C port is identical on the front and back. This means that no matter how you insert this port, it is correct. Users don’t have to worry about the positive and negative issues caused by traditional USB ports. In the past, the Micro USB interface had to be correctly inserted into the front and back, and it had to be distinguished before use. Sometimes the light was dim and the interface could not be plugged in. It was necessary to change the side, which was very bad in terms of experience. However, the Type C interface does not distinguish between the front and back. You can plug it in however you like. It is really convenient.
3. Main functions:
1. Fast
Compared with the early Micro USB interface, the transmission speed of the Type-C interface has been greatly improved. In theory, its maximum data transmission speed can reach 10Gbit/s. Although it is difficult to achieve in practice, it is already a breakthrough compared to the early interfaces.
2. Generalist
The Type-C port on the new Apple tablet can transmit data, charge, and can also be used as a video output port to connect to an external display device. The biggest question is how Apple can satisfy users who want to do these three things at the same time.
3. Two-way
Unlike older USB ports, which can only transmit power in one direction, the power transmission of the Type-C port is bidirectional, which means that it can have two ways of sending power. In addition to data transmission, the output voltage of Type-C has also been increased, providing power output up to 100W, shortening charging time, and realizing fast charging of various devices. Moreover, the Type-C interface can achieve two-way power supply: it can charge the device itself and provide power to external devices. Therefore, users can not only use their laptops to charge mobile devices, but also use other devices or mobile power sources to charge their laptops.
4.Backward compatibility
Type-C is compatible with the old USB standard, but users need to purchase an additional adapter to achieve compatibility. Apple said that not only Apple will officially sell the adapter, but third-party companies can also authorize the production. Compared with the early Micro USB interface, the Type C interface is compatible with other data interfaces, can transmit audio and video signals, and can be expanded to a variety of audio and video output interfaces, such as HDMI, DVI, and VGA interfaces, and can even be expanded to 4K resolution.
5. Specifications
The main promoters of the Type-C interface standard include Apple,Intel, Google, Microsoft and other major international companies.
