Micro USB vs TYPE-C
Introduction to Micro USB
Micro USB is a portable version of the USB 2.0 standard, which is smaller than the Mini USB interface used in some mobile phones, saves space, has a life and strength of up to 10,000 plugs and unplugs, 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 transmission between portable devices can be directly realized, compatible with USB1.1 (low speed: 1.5Mb/s, full speed: 12Mb/ s) and USB 2.0 (high-speed: 480Mb/s), providing data transmission and charging at the same time, especially suitable for high-speed (HS) or higher rate data transmission, to connect small devices (such as mobile phones, PDAs, digital cameras, digital video cameras) And portable digital players, etc.) the best choice.
At the same time, it can also provide convenience for the car, only need a USB car charger, plus a MICRO USB data cable for emergency charging of the mobile phone. And there is a 5V output interface directly on top of the high-end car, which is connected to the MICRO USB cable to charge the mobile phone. MICRO USB is versatile and easy to use.
Micro-USB is the next-generation specification of Mini-USB. The definition of the Micro series includes the Micro-B series socket used by standard equipment; the Micro-AB socket used by OTG equipment; Micro-A and Micro-B plugs, and cables cable. The uniqueness of the Micro series is that they include a stainless steel housing, which is not a problem for ten thousand times of insertion and removal.
Introduction to Type C
The Type-C interface, or USB-C for short, is located at the bottom of the smartphone and is used for charging and data transmission most of the time. 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 worldwide problem of "USB is never plugged in correctly". At the same time, the USB data cable used with it must be thinner and lighter.
1. Ultra-thin appearance
A thinner body requires a thinner port, which is one of the reasons why USB-C was born. 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. This also means that the end of the USB-C data cable will be one-third the size of a standard USB-A data cable plug.
2. No pros and cons
Like Apple's Lightning interface, the front and back of the USB-C port are the same. In other words, no matter how you plug in this port, it is correct. Users do not have to worry about the pros and cons of traditional USB ports.
In theory, the maximum transfer rate of the USB-C port is 10Gb per second. But Apple said that the USB-C port of the new MacBook has a maximum transfer rate of 5Gbps. The maximum output voltage is 20 volts, which can speed up the charging time. For the USB-A type, the limit transmission rate so far is 5Gbps and the output voltage is 5V.
The emergence of the Type-C interface can be said to save OCD and Virgo, and also make headaches such as "Law of Attraction" and "Murphy's Law" disappear.
The difference between Micro USB and Type-c
Micro USB and Type-C are both a kind of USB, and both have the functions of transmitting data and charging mobile phones. Their differences are mainly reflected in these aspects:
1. Obvious difference in appearance
Micro USB is narrower than Type-C interface, but has a stronger sense of weight. Although Type-C is wider, it appears thinner and lighter.
2. Different direction design
The Type-C interface has no distinction between positive and negative directions. Both positive and negative directions can be inserted. Micro USB has positive and negative directions. The wrong plugging will not only affect the cable plug itself, but also easily damage the mobile phone interface.
3. Differential transmission speed
The specification of micro USB limits the maximum voltage output, and there are limitations in charging technology. Type-C interface solves the problem of port limit voltage, and the maximum output power is greatly increased. The charging speed is improved.
In addition, the data transfer speed of Type-C is much faster than micro USB.
Who is more practical, Micro USB or Type-C?
Although Type-C is more functional, it is still slightly inferior in practicality. Because not all domestic mobile phones use the Type-C interface, most mobile phones continue the previous micro USB interface.
If one day goes out and forgets to bring the Type-C data cable, charging will be very troublesome. On the contrary, mobile phones with micro USB sockets are much more convenient and fast, and the micro USB data cable can be found easily.
In general, the Type-C data cable is a functional data cable, and its application scope is still limited. It is expected that there will be more room for development in the smart phone market in the future.
