With the development of laptops on the path of "lightweight", more and more laptops are now eliminating the USB A port, providing users with type-C ports that support forward and backward insertion. Some products have also eliminated a series of interfaces such as USB A to make the body lighter and thinner, concentrating input and output operations such as charging and external devices on the type-C port.

As a type c port that was referred to as the "Huawei port" by users in the early days, although it has a series of commendable advantages, for products like laptops, it is obviously not convenient to switch to a type c port, and at the same time, the functions required for the type c port have increased.

In most cases, the Type-C port on the mobile end is only used as a charging interface, while the Type-C port on the laptop end is used for both charging and expanding functions such as USB port and external display. Of course, some computers still retain the traditional USB port when providing the type-c interface.

But when users encounter laptops with type-c and USB ports coexisting, they will find that they provide relatively few functions. It cannot be used for charging or connecting devices such as monitors. It can only be used to connect USB drives and mobile phones for simple data transmission, and even the transmission speed does not have an advantage compared to some USB ports.

At this point, some users may ask why the same type-c interface functions are different? In fact, this situation arises because the type-c port can provide extremely high bandwidth and supports a variety of transmission protocols. And this also gives the type-C port flexibility in functional implementation, allowing computer manufacturers to customize the type-C port based on their own product positioning.

For example, on some laptops, the Type-C port that supports the Thunderbolt 4 protocol can not only serve as the charging interface for the laptop itself, but also connect a display with a resolution of up to 8K. At the same time, if connected to products such as the Green Link Thunderbolt 3 expansion dock, a maximum of 11 expansion interfaces can be derived to meet the interface requirements of all devices at once.

If computer manufacturers have relatively simple settings for the functions of the type-C port and want to provide users with only a "replacement" version of the USB port, then the things that the type-C port can do will naturally be much less. For example, a type-c port based on the USB 3.1 Gen 1 protocol may derive an extension interface from a better one, while a closer one can only be used to plug into a USB drive of the type-c port.

The functions that early type-C ports could achieve completely depend on the mood of computer manufacturers. However, after upstream chip manufacturers such as Intel intervene, they have started to standardize the specifications of type-C ports for laptops. In the future, laptops will become increasingly unified in terms of interface specifications and function implementation.

Back to the problem of the wide variety of type-c ports on the current laptop, as ordinary users, we can only spend a little effort to study the interface specifications when purchasing related products to avoid problems in daily use. In addition, when purchasing expansion products such as expansion dock, it is sufficient to identify a reliable and professional brand like Green Alliance.

High requirements for expansion performance can be directly connected to the Green Link Thunderbolt 3 expansion dock. A type-c port can derive 11 interfaces, and it also supports operations such as daisy chain. If you only need to connect a mouse and keyboard, or expand to a regular monitor, you can choose a green ten in one expansion dock, which can also meet daily expansion needs.

Although canceling HDMI, USB, and other interfaces may bring some trouble, it cannot be denied that this is a major trend in laptops. After all, the type-c interface not only has multiple functions to implement, but also has the advantages of forward and backward insertion, small size, and high flexibility, thereby providing users with a better user experience.
