With the popularity of smart devices, the market size of USB chargers is expanding. Its charger structure is very simple, with the same style and data cable, much lighter than the original charger, and suitable for home travel. With the development of technology, USB power adapters have also undergone great changes, such as multinational sockets, dual USB output, high power output, automatic adjustment, etc., which provide consumers with more choices, and also promote the sales of USB power adapters, but also promote the development of the industry. The seemingly inconspicuous small charger will provide people with an inconspicuous but very helpful role in work, study, life, and entertainment.
Interface Classification of USB Chargers
Type-A and Type-B
Type-A type interface is also the most common USB interface in our daily life, and can be said to be very popular, this interface I believe everyone knows, that most computers use this interface, it is compatible with serial ports, supports hot plugging, of course, the largest volume. Widely used in mice, keyboards, U disk, and other devices, Type-B type should be the most common mobile phone interface of old Android mobile phones, but the standard type-B interface is generally used in printers, audio, and other devices, its biggest feature is very durable, which is why it can occupy a place in the market for a long time.
Type-C interface is a new USB interface that has appeared in recent years, with only one shape. The Type-C interface has strong expandable capabilities, can transmit audio and video signals, expand to a variety of audio and video output interfaces, and even achieve extended transmission up to 4K resolution. The usb c charger here has three obvious features, first, the interface will be smaller, which is more suitable for all kinds of slim devices; Secondly, for users, the characteristics of forward and reverse plugging perfectly solve the problem of "difficult to align, to be plugged in many times"; This is followed by support for fast charging and bidirectional charging, which can freely change the direction of power delivery, both for charging itself and for external devices in reverse. Now the vast majority of mobile phone merchants on the market will use the Type C interface, and the future USB C Charger development prospect is huge.
MiniUSB interface is a small USB interface. On the USB standard, for some products that require a fast charging rate or quantity, two terminals and more than two terminals can be connected in parallel, to have more reliable functions and longer service life. Because of its small interface, it is very portable, and is usually used to connect mobile devices, such as MP3, MP4, radio, MP3 player, digital camera, etc., and some models of mobile phones also use this interface. The reliable and robust design provides a stable connection even after thousands of insertions; Long service life and high temperature resistance; The product is environmentally friendly. However, the main disadvantage is that the interface has low general compatibility, so it has certain limitations.
The MicroUSB interface, compared to the MiniUSB interface, is smaller in the case of almost the same width. Able to provide our devices with high-speed data transfer and fast charging. It has a very high penetration rate and can use the same data cable and charger to charge and transfer data to multiple devices. This makes transferring file data very fast and convenient in daily life or work.
All in all, the interface classification of USB charging cable is very varied, and each interface has its characteristics, which greatly facilitates people's work and life. With the development of the economy, the improvement of consumer income levels, and the popularity of smart devices, the Type C interface USB C charger, is a relatively new and better interface type, in future technological development, the Type-C interface will also become the representative of the mainstream interface, replacing the micro USB interface, becoming a wider application standard.
