Type profile

The type-c interface, or usb-c for short, is located at the bottom of the smartphone and is mostly used for charging, data transfer and other purposes. The biggest feature of type-c double-sided interfacing interface is that it supports double-sided interfacing of USB interface, which officially solves the worldwide problem of "USB never interfacing ". Both the front and back sides are interfacing at will. At the same time, the USB cable used with it must be smaller and lighter.

1. Ultra-thin appearance

A thinner body requires a thinner port, which is one of the reasons usb-c was born. Usb-c port is 0.83cm long and 0.26 cm wide. The old USB port was 1.4cm long and 0.65cm wide. This also means that the end of the usb-c cable will be 1/3 the size of the standard usb-a plug.

2. No pros and cons

Like apple's lightning port, the front and back of the usb-c port are the same. That is, no matter how you insert the port, it is correct. Users don't have to worry about the pros and cons of a traditional USB port.

3. Rapid

In theory, the usb-c port has a maximum transfer rate of 10 Gb per second. But apple says the new MacBook's usb-c port has a maximum transfer rate of 5 Gbps. The maximum output voltage is 20 volts, which speeds up charging time. Usb-a, so far, the limit transmission rate is 5 Gbps, the output voltage is 5 volts. The type-c interface arguably rescued ocd and virgo, as well as the disappearance of headaches, such as the law of attraction and murphy's law.

Introduction of micro usb

The MicroUSB, a portable version of the USB2.0 standard, is smaller than the MiniUSB port used in some phones, saves space, has a plug life and strength of up to 10,000 times, and has a blind plug design. Micro - USB standard support USB OTG function at present, in the absence of a host (such as personal computers), can be directly implement data transmission between portable devices, compatible with USB1.1 (low speed: 1.5 Mb/s, full speed: 12 Mb/s) and USB (high speed: 480 Mb/s), at the same time providing data transfer and charging, especially suitable for high speed (HS) or higher rate of data transmission, is the small equipment (such as mobile phone, PDA, digital cameras, digital cameras and portable digital player, etc.) the best choice. At the same time, it can also provide convenience for the car, which only needs a USB car charger and a MICROUSB data cable for emergency charging. And it has a 5V output port directly attached to the MICROUSB to charge the phone. MICROUSB is versatile and easy to use.

Micro-usb is the next generation specification for mini-usb, and its definitions include micro-b series slots for standard devices, micro-ab slots for OTG devices, micro-a and micro-b plugs, and cables. The unique feature of the micro series is that they contain stainless steel casings up to 10,000 times.

The difference between microusb and type-c

The MicroUSB and type-c are also USB, both of which can transmit data and charge mobile phones. Their differences are mainly reflected in the following aspects:

1. There are obvious differences in shape.

Micro usb is narrower than type-c, but has a stronger sense of thickness. Although type-c is wide, it is light and thin.

2. Different direction design.

There is no difference in the positive and negative directions of the type-c interface. Both positive and negative directions can be inserted. Micro usb has positive and negative directions, and the wrong plug will not only affect the plug itself, but also easily damage the phone interface.

3. Differential transmission speed

Micro usb's specification limits the output of the highest voltage and is limited in charging technology. The type-c interface solves the problem of limiting the voltage of the port, greatly increasing the maximum output power and improving the charging speed.

In addition, the type-c data transfer is much faster than micro usb.

Who is more practical, micro USB or type-c?

Although type-c is more functional, it is still a little less practical. Because not all mobile phones in China use type-c interface, most mobile phones still use the previous micro USB interface.

If you leave the house one day without the type-c cable, charging can be a hassle. On the contrary, micro USB plug-in phone is more convenient and fast, and it is easy to find micro USB data cable.

Generally speaking, type-c data line is a functional data line, and its application scope is still limited. It is expected that the future smartphone market will have great development space.
