The Type-C interface is one of the data interfaces of Android devices and is one of the mainstream data interfaces of Android devices at present. Type-C is a connection interface of USB interface. It can be inserted regardless of the front and back sides. It is about 8.3mm×2.5mm in size. Like other interfaces, it supports USB standard charging, data transmission, display output and other functions. The highlight of this interface is its slimmer design, faster transmission speed (up to 10Gbps) and more powerful power transmission (up to 100W). The biggest feature of the Type-C double-sided pluggable interface is that it supports double-sided insertion of the USB interface, which officially solves the global problem of "USB can never be inserted correctly". It can be inserted on the front and back sides. At the same time, the USB data cable used with it must also be thinner and lighter, and Type-C supports bidirectional power transmission, both sending and receiving power. This technology is simply called reverse charging. At present, many new mobile phones use this technology. Let's mainly introduce Type-C below.
Ultra-thin appearance
Thinner bodies require thinner ports, which is one of the reasons why USB-C came out. The USB-C port is 0.83 cm long and 0.26 cm wide. The old USB port is 1.4 cm long and 0.65 cm wide, which is outdated. This also means that the end of the USB-C data cable will be one-third the size of the standard USB-A type data cable plug.
No front and back
Like Apple's Lightning interface, the front and back of the USB-C port are the same. That is to say, no matter how you insert this port, it is correct. Users don't have to worry about the front and back problems caused by traditional USB ports.
Fast speed
Theoretically, the maximum transmission rate of the USB-C port is 10Gb per second. However, Apple said that the maximum transmission rate of the USB-C port of the new MacBook is 5Gbps. The maximum output voltage is 20 volts, which can speed up the charging time. The USB-A type has a maximum transmission rate of 5Gbps and an output voltage of 5 volts so far.
The emergence of the type-c interface can be said to have saved obsessive-compulsive disorder and Virgo, and also made headaches such as "Law of Attraction" and "Murphy's Law" disappear.
Micro USB Introduction
Micro USB is a portable version of the USB 2.0 standard. It is smaller than the Mini USB interface used in some mobile phones, saves space, has a plug-in life and strength of up to 10,000 times, and has a blind plug structure design. The Micro-USB standard supports the current USB OTG function, that is, in the absence of a host (such as a personal computer), data can be directly transmitted between portable devices. It is compatible with USB1.1 (low speed: 1.5Mb/s, full speed: 12Mb/s) and USB 2.0 (high speed: 480Mb/s), and provides data transmission and charging at the same time. It is particularly suitable for high-speed (HS) or higher data transmission. It is the best choice for connecting small devices (such as mobile phones, PDAs, digital cameras, digital video cameras and portable digital players, etc.). At the same time, it can also provide convenience for car use. You only need a USB car charger and a MICRO USB data cable for emergency charging of mobile phones. And there is a 5V output interface directly on high-end cars to connect the MICRO USB cable to charge the mobile phone. MICRO USB is widely used and easy to use.
Micro-USB is the next generation specification of Mini-USB. The definition of Micro series includes Micro-B series slots used by standard devices; Micro-AB slots used by OTG devices; Micro-A and Micro-B plugs, and cables. The uniqueness of Micro series is that they include stainless steel shells, which are not a problem for thousands of plugs and unplugs.
Differences between micro USB and type-c
Micro USB and type-c are both types of USB, and both have the function of transmitting data and charging mobile phones. Their differences are mainly reflected in the following aspects:
- Obvious difference in appearance
Micro USB is narrower than Type-C interface, but has a strong sense of heaviness. Although Type-C is wider, it looks thinner.
- Different direction design
Type-C interface has no positive and negative directions, and can be plugged in either direction. Micro USB has positive and negative directions. Wrong plugging will not only affect the line plug itself, but also easily damage the mobile phone interface.
- Different transmission speed
The specification of micro USB limits the output of the highest voltage, which is limited in charging technology. The Type-C interface solves the problem of port voltage limitation, and the maximum output power increases significantly. The charging speed is improved.
In addition, the data transmission speed of Type-C is much faster than that of micro USB.
Therefore, the Type-C interface is more practical than micro USB.
