　　What interface is USB-C?

Usb-c interface is called USB type-c, belongs to USB 3.0 next-generation interface, its bright spot lies in more thin design, faster transmission speed (up to 10Gbps), stronger power transmission (highest 100W), in addition Usb-c interface also supports double-sided insertion, the opposite side is casually inserted, More advanced than usb2.0/usb3.0.

Usb-c and USB transmission speed comparison

The Usb-c interface was December 2013, and the USB 3.0 Promotion team has unveiled the next-generation USB TYPE-C connector renderings, which were then ready for mass production in August 2014, and are now being used in smartphones and notebooks, For example, the Nokia N1 tablet and Apple's 2015 new Mac 12 laptops are all using the Usb-c interface, which can be easily understood as a fourth-generation USB interface.

　　USB Type-c Interface Features:

1. Ultra Thin

The old USB port is 14mm * 6.5mm long, while the usb-c is only 8.4mm * 2.6mm.

2. No positive or negative

As with the Lightning interface, no matter whether the Plug and reverse check will not have problems, claiming that can withstand 10,000 times repeatedly plug and pull.

3. Fast transmission speed

The maximum transmission rate of the USB-C port is 10Gb per second, much faster than the USB3.0.

4. Bidirectional transmission

Unlike the old USB port, the power can only be one-way transmission, usb-c-type Port power transmission is two-way, which means that it can have two kinds of transmission power mode.

5. Strong power supply capability

Standard specification connectors with TYPE-C connectors are available with a 3-a current, as well as "USB PD" that extends beyond the existing USB power supply to provide maximum 100W of power.

6, back to compatible

Usb-c can be compatible with old USB standards, but users need to purchase additional adapters to complete compatibility.

　　What's the difference between usb-c and USB?

Through the above Usb-c interface, I believe that the difference between the USB-C and USB interface is very clear. In short, the new generation of USB-C transmission faster than USB, power transmission is stronger, the interface size is smaller, and support two-way transmission, more compatible.

　　PostScript language:

The Usb-c interface is more than just the interface of an Apple MacBook Air 12 notebook, which will be the main interface for devices such as mobile phones, tablets, pc/notebooks, and so forth in the future. At the same time the Usb-c interface can be extended into a power/USB transmission/VGA or HDMI three interface, is the next-generation mainstream USB interface.
