The trouble is, it can be really hard figuring out which cables are good and which are not, unless you’re buying from a reliable vendor that provides good technical specifications. Now, to be fair, properly-made cables can have resistors inline to prevent this from happening. So, for example, if you plug a USB-A device (like a cell phone) into a USB-C port using one of these cables, the phone may draw too much power, frying your phone, USB-C port, or even computer. (USB-A, if you didn’t know, is the traditional USB plug we’ve all been using for years.) But, USB-C devices (and cables) support faster charging than USB-A.
The problem is specific to cables with the older USB-A connector on one end and the new USB-C connector on another.
