1.Micro usb interface:
The Micro usb charging interface is a portable version of the USB 2.0 standard and is the most common mobile charging interface on the market.
It has been more than ten years old. Previously appeared on Nokia phones, now almost exclusively on Android phones.
The Type-C interface is a charging interface that has only gradually emerged in recent years. This interface type has faster transmission speed and more powerful power transmission than Micro usb.
One of the biggest highlights is that the Type-C interface is inserted into the phone on both the front and the back. In the true sense, blind insertion is achieved.
3. 30-pin interface:
The 30-pin charging interface is a charging interface that has been used by Apple phones for up to 9 years. This type of interface not only has the functions of charging and data transmission, but also adds functions such as high-definition video output and photo import. For Apple, it makes a lot of sense.
However, this type of interface is very easy for the user to distinguish between the front and the back, and it is easy to insert and oppose the device to cause damage. Gradually replaced by the lightning interface.
The interface was released in 2012 with a new interface. This means that the lightning interface will completely replace Apple's 30-pin interface.
The lightning interface has a faster data transfer speed. Moreover, both the front and the back of the charging charging interface can be inserted, which solves the embarrassing situation that the 30-pin is difficult to distinguish between the front and the back.
