There are hundreds of USB C cables on the market, but not all that many of them are actually compatible with the official Type-C spec. A bad USB C cable can damage hardware with no visible warning, but so far there’s been no barrier for cables that aren’t compatible with Type-C spec. Google engineer Benson Leung has been working hard to post good reviews on compatible cables and post negative reviews on cables that are out of spec, but even his reviews can’t take the product off the market.
Amazon however is now taking action themselves to keep these cables off the market. Starting today sellers on Amazon are no longer permitted to sell cables that are not fully spec compliant. Under their “prohibited items” documentation they now list the following:
Any USB-C™ (or USB Type-C™) cable or adapter product that is not compliant with standard specifications issued by “USB Implementers Forum Inc.
Now that Amazon has this documentation in place, offending cables will most likely be removed and it will also force manufacturers to move to a Type-C compliant design for their USB C cables. There is one small caveat however, someone still has to notice if cables are out of spec. So if you happen to see a cable online, or are unfortunate enough to buy one which is not compliant with Type-C spec, you’ll need to report it so that Amazon can then take action against it.
