The micro USB 5pin male four pin patch board Android charging data interface universal charger interface standard specifies the overall structure of the charger and the interface on one side of the charger. The most widely used USB A interface is used, which not only solves the problem of universal charger, but also allows the phone to easily connect to the computer for charging or data transmission. The essence of this standard requirement is that "a USB interface is installed in the transformer", and the mobile phone charger is replaced by a MicroUSB data cable and a charger with a USB base. The charger base can no longer be the standard configuration for mobile phones, just a USB data cable is required, and it can also be charged directly from the PC interface. There are no relevant standard requirements for the interface on one side of the phone. Experts say that due to the advantages of Micro-USB compared to Mini-USB in terms of size, electrical characteristics, and plugging times, the Micro-USB interface will become mainstream. Our "Telecommunications Terminal Testing Technology Association" (TAF) conducted selective research on mobile phone side interfaces in September 2007, and the Micro USB interface has been included in the relevant pre plan. In the period of increasing global attention to environmental protection, in the near future, manufacturers may no longer include chargers when selling mobile phones to reduce pollution and waste caused by excess chargers; Consumers will no longer need to frequently change chargers when replacing their phones in the future, and may need to choose and purchase them themselves. The previous Micro USB interface was asymmetrical in width, so we needed to align it with the direction when charging. However, the Type-c interface was symmetrical and could be plugged in both front and back, bringing great convenience to people. In addition, this type of interface has many pins that can do more things. The interface supporting external device Type-c supports external USB devices. Only one Docking station is needed to connect your mobile phone or other devices to the mouse, keyboard and other peripherals, which provides great convenience for friends who do not carry a computer when they go out. Using external devices in combination with a mobile cloud computer or other office apps can greatly improve office efficiency, and can also connect USB flash drives through such interfaces, Easy to copy and backup files! [1] Convenient transmission. The Type-C data cable 5A 100W on the market is much faster than the traditional 3A and can provide power to high-power appliances such as display screens. Currently, there are mobile phones on the market that can "reverse charge" other phones through the Type-C data cable. You only need to prepare a Type-C to HDMI cable for mobile screen projection, and you can easily connect the device to the projector. The function is very powerful, and when you go out to work or want to watch a movie at home, a small cable connected to the large screen is definitely your best choice. In addition, this type of data cable also supports connecting to wired networks. We can connect our phones to the network through the Type-c adapter interface, but not all phones currently support this feature.
