USB Type-C™ Test Lab

According to IHS Markit’s market analysis report, the world’s shipment volume of electronic products with USB Type-C will reach 5 billion in the next three years. USB Type-C technologies are more complex than that of traditional USB. It can be plugged and unplugged on both positive and negative sides, supports USB 3.1 high-speed transmission, and has a power supply rate of up to 100W. However, due to factors such as design difficulty, it results in uneven product quality in the market, which not only leads to unpleasant user experience but also affects consumers’ purchase intention.


Allion’s USB Type-C laboratory has accumulated years of testing experiences. From the laboratory’s big data analysis, have have determined three major issues of USB Type-C

USB Type-C™ Comprehensive Testing Service

Pertaining to the above three major issues, Allion Lab has compiled from the database and came to a conclusion that PD and Data Transfer issues each account for one-third of the issues in all tested devices, and the number of device under test (DUT) of Type-C displays continues to increase by 70% every year. Based on the three major issues, Allion’s USB Type-C Lab is able to provide USB-IF standard testing, customize fast testing service, and interoperability testing.

I. Standard testing service
