Each year, manufacturers are committed to presenting the best of their technology in their products. The goal is not only to impress users but also to facilitate us by improving our user experience. Thus, last year, the first devices with a Type-C USB port appeared on the market, their main feature being both reversible. But this catch also hides some secrets and has some gray areas, at least as long as the standard is not available on all smartphones.
USB Type-C, what is it?
USB (Universal Serial Bus) is a standard cable and connection format for transmitting power and data between electronic devices. The USB is n in 1996 (USB 1.0) but it was not until 1998 that it really begins to be used (USB 1.1). In August, USB Type-C technology appeared. The latter works with the USB 3.0 standard but the rate is obviously better with the standard 3.1.
Be aware that there is a difference between the type of connector and the USB version. Each connector has a data rate as well as a limit on the intensity of the electrical current supported. The USB Type A and Type B plugs only have 4 connections, while the Type-C USB 3.1 ports offer 24 connections, which of course means more power and better speed.
For example, the Type B USB 2.0 currently available on most mid-range smartphones only supports 5V (volts) 2A (amps). USB 3.1 Type-C allows up to 20 volts 5A. The transfer rate of data passes thus 1.2 GB / s, against 60 MB / s in USB 2.0. Therefore, it is important to have a quality cable, slightly thicker, to support all this current.
The benefits of USB Type-C
In terms of reloading, the benefits brought by the new USB C type are numerous. Not only can you charge your smartphone from your laptop, but you can also charge your laptop via this USB type C. It is the new standard Power Delivery, USB PD, which takes care of that.
The Type-C USB port is also called "reversible". This quickly makes mistakes when charging the mobile but also to recharge the battery of one or more devices (depending on the size of the battery of the source).
Faster, more convenient and more reliable
In the near future, all the outlets of the laptops will be Type-C. The sound can also pass through this type of outlet, this is the case of the Lenovo Moto Z that uses the speakers with a USB port of this type. The next generation of HDMI will also be Type-C.
In summary, here are the USB standards:
- USB Hi-Speed ??(480 Mbps), or USB 2.0
- SuperSpeed ??USB (5 Gb / s), or USB 3.2 Gen 1: ex-USB 3.1 Gen 1, itself ex-USB 3.0
- SuperSpeed ??USB 10 Gbps (10 Gb / s), or USB 3.2 Gen 2: ex-USB 3.1 Gen 2
- SuperSpeed ??USB 20 Gbps (20 Gb / s), or USB 3.2 Gen 2×2
The disadvantages of USB Type-C
Some problems when you are not at home (temporary inconvnient)
Since the phones are so small with a Type-C USB port, it is rare to find compatible chargers when you are traveling or with friends. Finding a compatible cable with your device can be practically impossible mission. This is a problem if you have a smartphone with a standard USB port.
Not very common and still quite expensive (temporary inconvnient)
If you can try to solve the first problem by going to the first electronics store you encounter on the road, there are two other factors to consider. Type-C cables are more expensive than normal.
In addition, some cables have a Type-C USB output but are only compatible with the USB 2.0 standard, a very dangerous practice. If you use these cables with chargers and smartphones that have the Type-C standard with a bad version of USB, you can make your device unusable, as Benson Leung, a Google engineer, has done.
Not compatible with old accessories
Another problem you might encounter is the lack of accessories that are compatible with this connector. There are two choices: you either have to throw out the trash all your previous accessories, or you have to invest in an adapter.
Tips for using the Type-C USB port
- Check the Type-C USB cables you are using. Avoid buying those that are too affordable.
- Check that your smartphone with a Type-C USB port is compatible with USB 3.1
And you, are you conquered by the Type-C USB port?
