Type C’s history and function
In the era of fast charging, more and more large batteries accelerate the development of electronic devices. If you're still charging your phone for three hours a day and you're complaining if you don't plug in the charging cable, you're really outdated.
USB interface is one of the most commonly used interfaces of electronic products. The function of the new generation of USB Type-C has a significant leap compared with the previous generation. The maximum transmission rate of 10 Gbps and better power transmission performance are achieved. Consumers only need to use Type-C. The cable can be used for charging, video, or data transmission, eliminating the need to use a variety of cables. At the same time, the shape of the Type-C interface is the same on the front and back sides, and no one side will affect charging and transmission, thus solving the worldwide problem of “USB never inserted”. And its smaller size makes the body socket smaller and thinner. These advantages make the USB Type-C interface one of the fastest growing applications in the mobile market. "Charging for five minutes, talking for two hours" seems to have become a basic requirement for smart phones. Apple Macbook, Xiaomi, Huawei and other companies have adopted this interface in their new products.
Faster charging speed means higher charging voltage and charging current. The standard Type-C interface supports up to 5V/3A power supply parameters. Under the USB PD power transfer protocol, it can be expanded to an output voltage of 20V, an output current of up to 5A, and maximum 100W of power transmission. The standard USB Type-C data line supports only 3A of current. If you want to use USB Type-C as the charging interface to achieve 100W charging power, you need to have a matching USB Type-C charging cable.
In addition to hardware upgrades, manufacturers are also competing to launch their own fast-charging standards. In addition to the chip developer Qualcomm's QC and MediaTek's PE, such as OPPO's VOOC Flash Charger, Huawei SCP, One Plus Dash Charge, etc. also have their own markets. Qualcomm's Quick Charge 4.0 is currently designed for 5V/5.6A and 9V/3A. Huawei P10 Super Charge charger supports 5V/2A, 4.5V/5A, 5V/4.5A three-speed output, and automatically adjusts the output according to the body temperature and power. Meizu's mCharge Pro 6 Plus is equipped with a high-voltage fast charger, providing 5V/3A, 8V/3A, 12V/2A output power. This inevitably leads to compatibility problems. Different solutions cannot be compatible. Different terminal manufacturers using the same solution may not be compatible with each other. The upgrade of interfaces and standards also requires the upgrading of corresponding accessories. If you use a poor quality mobile power supply or charging cable, it may cause serious consequences of overheating or even explosion. Therefore, whether it is a regular mobile phone, tablet manufacturer, or a mixed data cable, charger, or mobile power supply market, you need a high speed and high speed. Performance power products test the Type-C interface and fast charging and charging equipment.
Why mobile phone must buy Type-c interface, after reading these you will know
Most Android phones now use the Type-c interface that can be inserted in both directions. Huawei, Glory, Xiaomi, Samsung, Meizu, Hammer, Nubian and other mobile phones all use the Tyep-c interface. The traditional front-side plug-in Micro-USB interface, in addition to some old models, basically only OPPO, vivo these two big names in use.
As Type-c gradually becomes a trend today, why do you have to buy a Type-c interface when you buy a mobile phone? The reason is not only that you can plug the data cable forward and backward to charge it. It will be easy to see the following.
What are the advantages of the Type-c interface over the Micro-USB interface?
Transmission speed: Type-c interface with USB3.1, data transmission speed up to 10Gbps;
Ease of use: Type-c interface can be inserted both positive and negative, greatly improving the ease of use of the USB interface;
Bi-directional power supply: The Typc-c interface can provide two-way power supply, both to the equipment itself and to external equipment;
Strong extension function: Type-c can transmit audio and video signals, and it can be expanded to a variety of audio and video output interfaces, such as HDMI, DVI, and VGA interfaces, and even achieve 4K resolution expansion...
In fact, the use of the Type-c interface in the use of specific scenes, the function is more extreme and humane, not only has the advantages of Android, but also based on its richness and expansion, the function has been further played, in use is also more The convenience.
