In the current society where electronic products are popular, people are not unfamiliar with the USB interface, TYPE-A, TYPE-B, TYPE-C are several common types of interfaces, the following we will look specifically at the different interfaces.
3 Different USB Interface Types
1. Type-A
Type-A standard interface is the most well-known type of USB interface, mainly used in computer PCs and chargers and other devices, is currently the most widely used USB interface standard. type-A interface has a positive and negative distinction, which means that the use of direct plug-in interface, there is a 50% error rate. So, users need to pay attention when operating.
2.Type-B
Type-B is less common in daily life than the aforementioned Type-A, and is generally used for external USB devices such as printers, scanners, USBHUBs, etc.
3.Type-C
Type-C is the latest type of mobile USB interface type, is currently a hot USB interface type, Type-C interface is the standard for USB 3.1, the maximum data transfer speed of 10Gbit/sec, the advantages of this interface is the compact design, socket end size of only 8.3mm × 2.5mm, fast transmission speed, the highest transmission speed of up to 10Gbps. It also has a strong power output capability of up to 100W. Type-C fast charging, for example, the traditional charger to charge the phone takes about 10 hours, while Type-C only takes 1 hour, or even faster. It should be noted that fast charging is not only determined by the "USB3.1type-c fast charging cable", but also depends on which fast charging technology the phone supports, and whether the charging adapter matches the support. That is, the three need to be unified in order to work together to achieve this "fast charging" task. Do not support the fast charging technology of the phone, the use of fast charging cable and charger, but also still after the "slow charging"
The Type-C trend was first led by Apple, the introduction of the new MacBook will be USB Type-c. This powerful technology brought to our attention. USB Type-C, is an interface specification that consists of a Type-C plug and a Type-C socket.
Development trend of the USB interface
Type-C interface is different from the other two interface types is the advantage that can support the USB interface double-sided plugging function, can withstand 10,000 repeated non-destructive plugging, which is mainly for small and thin portable mobile devices. Nowadays Type-C interface has gradually emerged to replace the Type-B and Micro USB trend.
In the case of reduced wear and tear, not limited by the direction, due to technical innovation, Type-C can take up less board space, which is actually not much practical change and significance for us outside the product, but for hardware product designers, a small change can bring more possibilities and changes to the internal layout afterwards.
The emergence of Type-C has completely solved the problem of plugging in the cable, there will be no more wrong plugging or mistakes caused by the failure of damaged equipment. Under the premise of normal operation, the technical innovation brought by Type-C can save the maximum space occupied by the board. Although the Type-C interface has many advantages, but the overall popularity rate is still not Type-A high, is also a troubling problem at this stage.
The difficulty of Type-C popularity is mainly because there are not many devices equipped with Type-C interface on the market, but with the successive launch of new devices, equipped with Type-C interface devices will also occupy the future of the electronics market, Type-C interface is expected to achieve universal access to become a unified USB interface standard for future portable devices.

1. Type-C interface extension sockets
In order to meet the needs of consumers, the extension socket products are also based on the original USB Type-A, the development of Type-C interface. For example, the following style of mop-up board, from the initial 3-bit, then developed to increase the Type-A interface, and now joined the Type-C. The next five years, the Type-C interface consumer population will show a spurt of growth. This type of mop-up board will also be more and more popular in the market by consumers.
2. Type-C interface charger
Also, with the popularity of Type-C interface, many chargers have also joined the relevant interface design.
The following common charging interface style, 2 Type-A plus a Type-C, when used alone Type-C fast charging hole, charging efficiency of 30W, and when used simultaneously with two Type-A interface, Type-C interface charging efficiency of 20W.
If you are a buyer of this type of product, you can pay more attention to the relevant product new release. Because of the gradual fierce competition in the market, many hot styles will be underwritten, and advance planning of products, not only in terms of suppliers have more choices, in the consumer side also reflects the high degree of professionalism of the brand.
