What is the Type-C interface? What are the advantages and disadvantages of the Type-C interface?
The Type-C interface is a type of USB connection interface that allows for reversible insertion, meaning it can be plugged in regardless of its orientation. It has a compact size of approximately 8.3mm x 2.5mm and supports various functions such as charging, data transfer, and display output, similar to other USB standards. The Type-C interface was developed by the USB Implementers Forum and gained support from major companies like Apple, Google, Intel, and Microsoft, leading to its widespread adoption starting in 2014.
To understand Type-C, it’s necessary to mention the other USB interface types. Currently, there are three main USB interface types: Type-A (Standard-A), Type-B (Micro-B), and Type-C. Type-A is the most widely used interface found in computers and electronic accessories, such as mice, USB drives, and larger-sized connectors. Type-B is mainly used for devices like 3.5-inch hard drives, printers, and monitors, with a smaller form factor compared to Type-A. In addition, there are Mini USB and the upgraded Micro USB standards developed for enhanced portability in mobile electronic devices. Micro USB is commonly found in smartphones.
Furthermore, there have been five USB versions released so far: 1.0/1.1/2.0/3.0/3.1. The Type-C interface standard was introduced alongside the USB 3.1 version. However, it’s important to note that Type-C does not require a specific USB version and can even be used with older USB 2.0 versions. For example, devices like the Nokia N1 tablet, OnePlus and LeEco smartphones use the older USB 2.0 version with a Type-C interface. The recently released ZUK Z1 uses the USB 3.0 version. Even Apple’s 12-inch MacBook, which promotes the use of USB 3.1 Type-C, does not fully implement USB 3.1. It utilizes USB 3.1 Gen1, which has a half-speed transfer rate (5Gbps) compared to the standard, and a future full-speed version would be USB 3.1 Gen2. Therefore, Apple’s USB 3.1 Gen1 is essentially a Type-C version of USB 3.0, with a name change for marketing purposes.
Advantages of Type-C:
Reversible insertion: The most well-known advantage of Type-C is its reversible insertion. It can be plugged in regardless of its orientation, which eliminates the need to worry about the correct orientation like with Micro-USB connectors. This was a significant reason for Apple’s decision to abandon the Thunderbolt 2 interface previously used.
Slim and compact: Type-C has a slim form factor, approximately 8.3mm x 2.5mm in size. It takes up minimal space in mobile devices and saves two-thirds of space when used in laptops.
Full USB 3.1 functionality: Type-C fully supports all features of USB 3.1, including high power delivery of up to 100W, a maximum transfer rate of 10Gbps, and the ability to transmit audio and video signals. Particularly notable is the bidirectional power delivery capability of Type-C, allowing devices to both charge the connected device and be charged by other devices or power banks.
Additionally, there have been rumors of Apple replacing the Lightning connector with Type-C on the iPhone 6s. Combined with Type-C’s support for audio signal transmission, the previous rumors about Apple removing the headphone jack were not baseless. Therefore, due to Type-C, future smartphones may have only one interface.
