USB-C can play Russian roulette with your laptop when you try to connect another device to it

Throughout the past year, the issue of the new USB standard, USB Type-C, has been actively discussed on technology portals. A huge plus is its versatility. So, USB Type-C can work with a wide range of devices - from monitors and smartphones to any other new type of gadgets that may appear. In addition, now there is no need to guess which side to insert the cable into the connector - it is possible this way and that.

USB-C quickly found support among large technology companies. Apple and Google were the first to launch USB Type-C laptops, and now they can be found on PCs, tablets, and phones. The cable is transmitting both energy and data, and the bandwidth of the communication channel is quite large. But, as it turned out, not everything is so rosy.

The fact is that if you are not careful, USB-Ccan destroy a laptop . Noname cable manufacturers, who began to mass-produce USB-C wires, are not always careful about their products. And if there were no problems with the old cables - if there is a marriage, then the maximum trouble for the user was a non-working cable, now the situation is worse.

Google engineer Benson Leung, who decided to test the USB-C cable, destroyed his own Chromebook Pixel. After that, deciding to figure out the problem, he destroyed two more devices like USB PD. Something similar happened with the journalist of TheVerge - he tried to charge his Nexus 6P from MacBook Air with an inexpensive cable, and as a result got problems with the laptop ports - now they work unstable. The engineer began testing cables last year, about which a corresponding article was published at Geektimes .

And everything said earlier is still relevant, although a lot of time has passed. The problem is that some cables from different manufacturers do not include a system for protecting laptop ports from too active energy consumption connected via USB-C to a smartphone or tablet. There were problems before, many old USB cables also have no protection, but previous models of USB gadgets simply did not consume that much power.

How to protect yourself from a problem? It seems to be a simple solution - do not buy too cheap cables. But “buy an expensive cable and solve the problem” is also not an option. Now, if you want to buy a really safe cable, you should pay attention to reviews from buyers. In particular, reviews of the same Google engineer. He is specifically engaged in the purchase and study of cables from various manufacturers.

The information received is collected here , here and here . The problem usually lies in the fact that the manufacturer's stated support for the current strength of 3A is not true - the cable will not be able to work normally at full load.

There is another option - look for certified USB-IF cables that are marked with this marking:

Currently certified 61 cable models from various manufacturers.

But the problem is also that such logos cannot yet be found on Amazon and some other resources. If you buy a USB-C cable on Amazon, you need to go and check the plates, the links to which were posted above.

Otherwise, a cable for a few dollars can destroy your expensive laptop worth several hundred dollars. So be careful.
