For the past few months Benson Leung, a Googler, has been reviewing USB Type-C cables easily available for purchase online. He has come across quite a lot of cables that are not fully compliant with the USB Type-C standard, meaning that they’re not safe and could potentially end up harming the device. He now has a big ally in his fight against bad cables, Amazon has updated its prohibited listing guidelines to declare that USB Type-C cables that are not fully spec compliant will not be sold through its online marketplace.

“Any USB-C™ (or USB Type-C™) cable or adapter product that is not compliant with standard specifications issued by “USB Implementers Forum Inc” is now mentioned under Amazon’s prohibited listing guidelines.

Amazon is the number one online destination for buying things like cables and what not, and Leung found in his reviews that many of the cables being sold through Amazon had the wrong resistor, which means the cable can draw excess power and end up damaging the port on your device.

The online retailer has now declared that USB Type-C cables that are not fully spec compliant can not be sold through Amazon, so any such cables that were previously listed on Amazon will now be pulled.
