A Google engineer volunteered to test a USB Type-C cable sold on Amazon's Web store, only to cause a disaster. In addition to most of the cable design is not standard, when he tried to connect a brand of USB 3.1 Type-C cable to the Chromebook Pixel, because the two wires in the cable were welded incorrectly, resulting in the power to the wrong place, so that his personal Chromebook Pixel was burned. In February 2016, Apple issued an emergency recall for a batch of original USB Type-C cables manufactured before June 2015 due to defective cable design, which could cause users' MacBooks to fail to charge or intermittently charge.
When many manufacturers compete to invest in USB Type-C technology, the problems that accompany the market also follow. USB Type-C supports both front and back plug, supports 10Gbit/s high-speed transmission, and the application of Power Delivery (PD) technology makes power and data transmission support individual direction operation, and the power supply rate jumps from 7.5W of BC 1.2 version to 100W characteristics. In addition to the Charging specifications of the USB-IF charging specification, USB Type-C also assumes the support of the traditional USB interface for Quick Charging (QC); In addition, it can run audio and video signals in the same cable in Alt Mode, so its technical application and conflict are relatively complex compared with traditional USB; In addition to complying with the USB-IF standard specification during the development phase to ensure product quality and safety design compliance, manufacturers also need to verify that their Type-C products (including cables) can operate smoothly with other products under different use situations (USB Type-C ecosystem interoperability icon). To prevent the occurrence of abnormal power supply, system shutdown, and even component burning, resulting in adverse user experience.
