Before Type-C and Apple’s lightening interface becomes prevalent, Micro USB was the “king” of the data cable and interface market. This was due to the fact that it was born at a optimal time and situation.
In 2007, the OMTP announced Micro USB as the next generation for the Mini-USB interface and announced that it would become the standard interface for data and power for mobile devices. And in 2009, in order to reduce the mechanical wear of frequent cables and interfaces in the mobile device market, the International Telecommunication Union (ITU) completed the discussion and adoption of a framework standard for “Power adapters and chargers for universal mobile devices and other ICT devices”, a framework which mark the global standardization of cell phone chargers. In addition, the European Union has also mandated that by 2017, all cell phones sold in the member states must have a Micro-USB port.
What are the advantages of Micro-USB? First of all, compared with the previous generation Mini USB, its size is more “mini”, although the width is similar to mini USB, Micro USB is flatter by half (1.8 mm). The OTG function also allows it to transfer data between portable devices even without a host.
