The new standard USB-C is on the lips of all the technology industry, starting with the smartphone manufacturers. But the revolution could be bitter for anyone who doesn’t pay attention: the risk of damage is very real.
It is understandable why USB type C is the future. From a practical point of view, it meets one of the biggest criticisms of the format USB (at the origin of many memes on the net) is reversible: can not go wrong direction of insertion. And it’s also incredibly compact, positioning itself in terms of size between the Micro USB 2.0 (the most common) and the Micro USB 3.0 (more slender) while being far more robust than the latter.
Small but powerful
But these are technical skills that make him a true revolution in terms of connectivity: able to transfer data, video and a current electric, she is the current the most versatile connectivity.
This versatility, however, is not at the expense of its performance, since the USB Type C coupled to 3.1 USB allows to provide 60W of power (against 4, 5W for the current USB3) 100Wfor the new standard USB Power Delivery 2.0.
As a result, it allows waterproof smartphones and tablets (view http://www.computerannals.com/2016/top-5-waterproof-smartphones.html), such as the Nexus 6 p or the Pixel C, of to load more quickly while allowing new uses as external graphics for laptops (like the Razer Blade Stealth) or a second external display USB powered without provided a larger space in the components.
His flows are also impressive. The USB 3.0 standard already allows a more than adequate flow of 5Gbits/s, but the new 3.1 USB standard supported by the USB Type C format allows to reach a monstrous rate of 10 Gbps. The evolution of the technology curve made a leap forward thanks to this new medium, which allows a perfect marriage between practice (Type C format) and power (standard USB 3.1).
A cable independent multi-function
Design of a USB Type C cable is more complex than a classic cable, since it incorporates within itself an electronic circuit that does give the ID and the capabilities of the connector to the power unit.
And, recognition of the material power of USB Type C is cable that indicates its maximum flow independently and its maximum supported load. This process is similar to Quick load of Qualcomm, which is based on an agreement between the host and the receiver to determine the load of current sent.
Except that there is an agreement between 2 chips (Qualcomm) owners, namely that the charger/host and the smartphone/receiver, and that to succeed in reaching a load of 18W he takes control of the bands reserved for the transfer of data. USB Type C contrast didn’t need this to reach 15W, and can make use of these bands without a proprietary technology is used.
This is where the circuit integrated into USB type C makes sense, since it is he who’s role is to communicate with its host in order to determine the load to send. In the case of the USB3.1 for example, it can thus switch mode Gen1 with the 3 USB and USB 2 and be sure not to overstep the limits of the host.
Due to the fact that the Quick Charge is a proprietary technology and requires a Qualcomm chip at both ends of the process, the risk of truly damaging its equipment was lower on a format USB 3.0 A classic.
However, it is no longer the case with USB Type C. Indeed, the relationship between the host and the cable is this direct, a poorly designed cable can have a direct and disastrous consequence on your equipment which would take much more that it cannot.
This is particularly the case of the cable USB Type C sold by OnePlus, which instead of the standard and its power management directly uses an identifier 3A. Because of this, it is at risk to ask his host more power as possible and damage it doing too well the source material than the USB port of the equipment.
Attractive price? Smartphone in danger
The fact is that right now, the Smartphone market is not yet ready to switch to the USB Type C in 2016. The direct consequence is that the offer by cable USB Type C is made almost exclusively by unscrupulous merchants seeking to make the most profit possible before the flood.
We are therefore left with the cables together, or very quickly transformed from USB A to USB C without inspection. These unscrupulous companies having not any worries to stick a label certifying a control of European standards without that no legal test has been done, much less losing a trial that it brings, you have to be vigilant.
This problem affecting both the Micro USB to USB Type C adapters (or), USB Type C male and female connectors and simple cables, the caution is required. As online stores have no additional quality control: merchants are records they want, say what they want, without that person if the buyer doesn’t come to contradict them.
We therefore recommend caution until USB Type C is really adopted. The temporary solution, if you need cable USB Type C, is to trust big brands like Google for which the respect of European standards is not esquivable and which comply with the standards of their media.
The consequences can be disastrous and destroy your smartphone 700 within a few charges, pay a cable €5 is so better than it looks. But don’t worry, the arrival of the USB Type C on the next Samsung Galaxy S7 will soon allow an offer consistent and quality.
