China's Ministry of Industry and Information Technology (MIIT) has published 125 recommended standards for the telecom industry, among which mobile telecom terminal standard YD/T 1591-2009, titled "Technical Requirements and Test Methods for Chargers and Data Interfaces for Mobile Telecommunications Terminals," recommends that handset chargers adopt a three-section design, including three types of connections. The standard recommends that chargers include round, mini-USB and micro-USB connections such that one charger can be used to charge different brands and models of handsets. According to the standards, power adapters will not only function for charging, but also for data transmission, and should function with not only handsets, but also with Bluetooth earphones, cameras, radios, electric razors, and other small electric appliances of many types.
On January 7, the MIIT's China Telecommunications Technology Labs (CTTL) undertook a special project to draft a unified standard for handset chargers and data ports, to be published in the coming days. CTTL standards drafting group director He Guili believes that once the unified standard has been officially published, handset charging ports will be standardized. "Handsets and chargers will be able to be sold separately," said He.
