A simple USB Type C cable (or simply USB C) can seriously damage your expensive devices or equipment, so it is highly recommended to choose a good and safe one (which meets the standards of this technology)..
To be exact, the problem appears in the cables «USB C to USB A» (or vice versa), that is to say, those that have the USB Type C connector at one end (it is a small reversible connector that plugs in two directions) and the conventional USB connector of the other (USB Type A). The danger is that devices with a USB C slot (such as some modern cell phones) can handle a much greater amount of power than devices or computers with a USB A slot (such as most modern laptops or PCs). When charging a USB C cell phone in a USB A laptop, the cable should warn the phone that the other end is USB A and that it should limit its power consumption. When the cable doesn't do this job, the mobile sucks or requires more power than USB A could provide, damaging the host computer (in this case the laptop).
Amazon sells secure USB Type-C cables
Due to this situation, the Amazon online store updated its policy for the sale of electronic products, prohibiting any USB Type C cable from being offered in it that does not comply with the standard specifications issued by the corporation that created USB technology (USB Implementers Forum). In this way it is assumed that any USB Type C cable sold in this store should be safe, although it should not be taken for granted due to the massive number of products handled by this store. It is best to confirm the goodness of the brand of a cable with an expert..

USB C cables reviewed by a Google Engineer
Google Engineer Benson Leung, part of the team in charge of Google's Pixel product line, is an expert on the subject of USB Type-C cables and has spent part of his time reviewing different brands of these types of cables that he has purchased from Amazon . The observations and rating that you have given to each of these cables can be seen in the same store.
Leung's work has been echoed by many websites, republishing in listing form the "good" and "bad" USB C cables identified by this engineer. There are resources that compile the cables reviewed by him (and other cables tested in other ways, in addition to USB Type-C accessories), as well as websites like this one that list only the good cables and the links where they can be purchased..
Benson Leung and his experience
A USB C cable that did not meet the technical specifications of this standard burned a $ 1,500 computer of this engineer (Google Pixel 2) during his tests. That's how dangerous it is to buy a "bad" USB Type-C cable. And this is not limited to third-party cables, because even manufacturers have fallen into this error: the original USB Type C cable of the OnePlus 2 worked well with this device, but it could damage other equipment that will use it, because it did not comply properly with all the technical specifications, and this was made known by Benson Leung himself.
How to tell if a USB C cable is good or bad (Nexus 5X and 6P)
To find out if a USB Type-C cable is safe for a Nexus 5X and 6P device you can use the Checkr app , which immediately indicates whether the cable is good or bad when reconnected. The APK of this application can be found on the website apkmirror.com .
Another way to check if the cable is apparently safe for one of these devices is through the command line, from the PC ( ADB ) or from the Android device. Just send a command and the returned response determines whether or not the cable is compliant with the USB Type-C standard.
