In the modern, technologically advanced, smart phones, even in remote rural areas can be seen.
But have you observed the charging interface of the mobile phone? It can be seen that there are currently three types of mobile phone interfaces that are most common in our lives, corresponding to three charging lines.
The average person calls these three charging lines: Apple charging cable, Android charging cable, Xiaomi charging cable…
Although it is correct, it is too unprofessional! I will come to the science to talk about these three charging lines today!
1. Lightning interface used on the iPhone, Apple’s official Chinese called lightning interface
Released with iPhone 5 in September 2012. The biggest feature is small size, can be inserted in the front and back, and the black charging does not need to be turned over and turned over. In addition, it is not only small in size, but also supports a variety of functions: in addition to charging and transferring files, it also supports digital signal (video, audio, real-time synchronization of mobile phone screen) output, connecting various supported hardware (such as audio, projection, car navigation) ) and reversely control some of the corresponding functions on the phone through hardware.
Disadvantages: Even with the iPhone 8 after the machine, the Lightning interface uses the original line to transfer files and charging speed is very slow, slow and slow. I bought a third-party fast charge kit that can achieve fast charging, but the speed of transferring data is still slow.
2. Micro USB
In September 2007, OMTP (an organization of a bunch of communications companies) announced the global unified mobile phone charger interface standard Micro USB, characterized by small size.
Advantages: low cost, whether it is consumers or producers.
If you still have to say that one advantage is that the home is usually an electronic product, the socket is generally this socket, you can use it with a single usb, do not know whether it is crying or laughing, charging is really fast, performance is really weak.
Disadvantages: does not support positive and negative insertion, the interface is not strong enough and easy to damage (although the maintenance cost is low), poor scalability.
3. USB T ype-C, hereinafter referred to as C port
Mass production began in August 2014, and in November, the first Nokia N1, a consumer electronics product that uses C-port, was released. In March 2015, Apple released a MacBook using the C port. The entire laptop has only one C port, which integrates all the functions of the interface. After that, the C port is brought to the fire.
Advantage: powerful Charging, high-speed transmission, 4K quality output, digital audio output… Existing devices that can be connected by wires can be connected through C port. Support positive and negative insertion, small size.
C port will be the trend of the future, whether it is a mobile phone or a computer, will gradually change to a more compact and compact C port.
Disadvantages: high cost.
Therefore, in order to save costs, some manufacturers have reduced the functions of the C port on some mobile phones to only charging and data transmission, and other audio output, video output, and even OTG functions are gone.
