Currently there are three main mainstream cell phone charger interface: Micro USB interface, USB Type C interface, Lightning interface.
1, Micro USB interface
Micro USB is a portable version of the USB 2.0 standard, smaller than some of the cell phone using the Mini USB interface, Micro-USB is the next generation of Mini-USB specifications by the USB standardization organization USB Implementers Forum (USB-IF) in January 4, 2007 to develop and complete.
2、USB Type C interface
USB Type-C is a new form of USB interface (USB interface and Type-A and Type-B), which accompanies the latest USB 3.1 standard came out of nowhere. Released by the USB-IF organization in August 2014, is the USB standardization organization in order to solve the USB interface for a long time the physical interface specification is not uniform, the power can only be unidirectional transmission and other shortcomings and the development of a new interface, which set charging, display, data transmission and other functions in one.
3、Lightning interface
Apple's high-speed multifunctional I/O interface is September 12, 2012, the United States, San Francisco Convention Center Apple released a new Lightning Dock interface, which can be translated into Chinese as "lightning" interface. The release of the new interface standard also means that the 30-pin Dock interface, which Apple has used for nine years, will be officially replaced.
Extended information:
The characteristics of the three charger interfaces are as follows:
1, MicroUSB interface features: portable, smaller interface, space-saving. With up to 10,000 times of plug life and strength, blind plug structure design. Support the current USB OTG function, can provide charging and data transmission at the same time and so on.
2, Type-c interface features: thin, 0.83 cm long and 0.26 cm wide. And the old USB port is 1.4 centimeters long and 0.65 centimeters wide. Support USB interface double-sided insertion, solving the "USB never plugged in" big problem.
3, Lighting interface features: small size, Lighting front and back sides have 8 contacts, the function of each contact is defined by the digital chip, greatly reducing the space at the bottom.
