USB3.1 advantages: positive and negative casually plug
The traditional USB interface requires repeated plugging, looking for "correct" direction has been widely criticized by consumers, and USB3.1 double-sided plug-in interface biggest feature is the support of USB interface, double-sided insert, like Apple's Lightning interface , USB3.1 port front and back are the same, users do not have to worry about the positive and negative issues brought by the traditional USB port, the official solution to the "USB never get in the world" problem. At the same time with it supporting the use of USB data cable must also be more detailed and lighter, faster transfer speed.
In USB 2.0, the maximum transmission speed can reach 480Mbps, while in USB3.1 belongs to USB 3.1, the theoretical maximum data transfer speed of 10Gbit / sec, is the USB 3.1 standard, but Apple said the MacBook USB3.1 port highest The transfer rate is 5Gbps. Compared with USB 2.0, it can be said that there is a qualitative leap.
Can charge in both directions
We currently use the USB port, the power can only be one-way transmission, USB3.1 port power transmission is bi-directional, which means it can have two ways to send power. And USB 3.1 standard is 20V, 5A, that is, the output power of up to 100W. At present, the largest notebook is also the need for 60W power supply, so users can now not only laptop for mobile device charging, you can also use other devices or mobile power for laptop charging.
Why USB3.1
As we said before, notebook thin and light is the trend of the times, the traditional "large" USB interface size has been difficult to meet the needs of equipment manufacturers and consumers. The MacBook 24% thinner than the previous 11-inch MacBook Air, while the USB3.1 interface socket size is about 8.3mm × 2.5mm slim design, thinner body requires thinner ports, which is Apple to use USB3.1 one of the major reasons.
1.Transmission speed: USB3.1 data transmission speed up to 10Gbps;
2. Source high-end technology: support for downlink charging
3. Non-directional: USB3.1 interface is not directional, that is, both positive and negative insert can be completed pairing, greatly improving the usability of the USB interface.
4. Power supply capability: through the USB3.1 interface to external devices
