USB Type-C – Everything you need to know


Every year manufacturers are more committed to introducing the best in their products not only to impress, but also to improve our life and user experience. During the last year we have seen the famous USB type C land, whose main characteristic is to be reversible. But it still hides some more secrets and has a dark side until the standard is normalized.

What is USB Type-C?

USB (Universal Serial Bus) is a standard of cables and connections for passing electrical energy and data between electronic devices. The first standard came in 1998 and in August 2014 saw the latest light, the famous USB Type C along with a new version of data exchange speeds and power step, USB 3.1.
There is a difference between the type of connector and the USB version. That is, each form of connector has a data rate and a limit on the current of the electric current it supports. The pins with USB Type A and Type B only have 4 connections, but the pins with USB 3.1 Type C have 24, so they support more energy and speed.For example, the USB 2.0 type micro-B that currently has most smartphones only supports 5V (volts) to 2A (amps) and a transmission rate of 480 Mbit / s; A USB 3.1 Type C reaches up to 20V to 5A and with a transmission speed of up to 10 Gbit / s. For this reason it is not worth any cable for a Type C USB, they are usually thicker to withstand all that electricity.

Advantages of USB Type C

The advantages of having a new standard are quite clear as more power and more speed. But it is also accompanied by a reversible Type C plug, that is, it does not matter the orientation in which you connect it since it works in any position.In the very near future all the connections of a laptop will be USB type C because having data and a lot of energy can become whatever. There are already initiatives by Intel for the digital sound is passed to the USB Type C, goodbye to the headphone jack and the Moto Z . The next generation of HDMI will also be via the USB type C. And for the power supply the USB Type C supports up to 100W, and a laptop works with about 19W.

Disadvantages of USB Type C

Dangerous Cables with Type C plug and USB 2.0 standard
Not all manufacturers are adjusting to the new standard. Some cables have a USB Type C plug but only include the USB 2.0 standard, a very dangerous practice. If we use these cables with chargers and smartphones that do have the Type C standard, USB 3.1, we can reach unusable leave your smartphone or tablet as it happened to Benson Leung , Google engineer

USB Type C is incompatible with traditional fast charging (it’s more of an advantage)

This is not really an inconvenience but it goes against the prejudice we have about fast charging. Qualcomm’s Quick Charge, Motorola’s Turbo Charge or the OPPO VOOC Flash Charge use the data line to provide extra power in USB 2.0. In USB 3.1 this is prohibited as the data line can only be used for data.
The Type C power does not need to use the data line as it supports much more electricity (100W) than the traditional fast load (18W), in fact it can be up to 5 times faster (theoretically) than the current fast load.

It is still not very common and a bit expensive

At the moment there are not many devices and cables that truly fit the standard. The only devices that comply with USB 3.1 Type C to the letter are the Google terminals (Pixel C, Nexus 5X, Nexus 6P, Pixel and Pixel XL).

Tips for using USB Type C

  • Watch out for cheap Type C USB cables, they can be very expensive.
  • Although the smartphone has a USB Type C looks good in the specifications as it may not support as much load as the standard USB 3.1 promises.
  • Always use the cable and charger that come with the device.
  • If you need a spare, find out sooner if it is of quality and compatible with your device.
