Purchase | Understand that consumption refuses to be fooled
Nowadays, many users want to buy a product that is thin enough when choosing a laptop, but when some extremely thin laptops are really placed on the user's desk, users are often stunned - because they are familiar with interfaces, such as standard USB ports, VGA ports, and HDMI ports, there are no more. There are only a few Type-C USB ports (or Lightning 3 ports) there, so how to connect and use the normal settings? This requires Type-C expansion devices.
—— Basic knowledge Charging
Type-C USB interface and Thunderbolt 3 interface both adopt Type-C specifications. There is no difference in appearance design between the two. The only difference is the bus. There is no necessary connection between the device using Type-C interface and the bus. This also means that even if the current interface specifications of Type-C USB and Thunderbolt 3 are the same, the functions that can be implemented are not completely consistent. Judging from the current products, many mobile phones and tablets use Type-C USB interfaces, but many of them use USB2.0 buses, and their transmission rates can only meet the performance of the USB2.0 specification. Most of the USB buses that use Type-C on laptops use USB3.1, and the theoretical bandwidth reaches 10Gbps.

. The Thunderbolt 3 adopts the Type-C interface has a theoretical bandwidth of 40Gbps. It not only supports USB3.1 bus, but also uses its own high bandwidth to expand functions and performance, such as supporting picture output, USB3.1, audio output, and network at the same time, and can even support independent graphics... So now many notebooks only have Thunderbolt 3 interfaces, and then paired with a dock to achieve various functions. For thin and light notebooks, this ensures portability while meeting users' functional and performance needs.

— I want to connect to a USB device Type-C to USB3.0 adapter
Market price: about 15 yuan
Applicable interface: All Type-C interface
Functional features: USB devices connected to traditional Type-A interface
For users who want to use traditional USB devices on laptops with Type-C interface, various accessories manufacturers on the market have launched Type-C to USB3.0 adapters. In this way, on the latest thin and light laptops, users can use any USB devices that adopt Type-A standard, including USB2.0 and USB3.0 storage devices, mouse, keyboard, etc. Basically, if you buy a adapter like this, users don’t have to worry about their USB devices being useless on their new laptops. Adapters like
are everywhere on the market, usually around 15 yuan, and counterfeit manufacturers may be less than 10 yuan. It is recommended to buy products such as GreenLink and CE-Link. Since it is only for USB devices, it can connect to both the Type-C USB interface and the Thunderbolt 3 interface. If it is connected to a Type-C interface mobile phone, it also supports OTG function, so it is still necessary to buy one at home.
—— I want to have a wired Internet Type-C to Gigabit Network adapter
Market price: about 80 yuan
Applicable interface: All Type-C interfaces
Functional features: Use the Type-C interface to make laptops have gigabit network interface
Many notebooks have an RJ45 gigabit network port, but the latest thin and light notebooks are not necessarily the case. In addition to supporting wireless networks, network ports are generally not designed. So what should I do in an environment where wired networks are necessary? Then you can only buy a Type-C to RJ45 adapter.
Generally speaking, this adapter generally supports gigabit network, and the price is not too cheap. It is recommended to buy products that are not less than 80 yuan. The adapter already comes with a network chip, and the specifications of USB3.1 and Thunderbolt 3 can easily reach the speed of a gigabit network. However, if there are some products (such as some tablets) that use a USB2.0 bus on the Type-C USB interface, the network transmission speed cannot reach the limit of a gigabit network. After all, the USB2.0 speed is 480Mbps, so you should pay attention to this point.
—— I want to output video Type-C to HDMI adapter
Market price: about 100 yuan
Applicable interface: Thunderbolt 3
Functional features: Connecting the Thunderbolt 3 interface allows the laptop to output video through HDMI cable
HDMI1.4a's bandwidth reaches 10.2Gbps, so if you want to output video on thin and light laptops without HDMI interface, in addition to purchasing the Type-C to HDMI adapter, you also need to plug the adapter on the Thunderbolt 3 interface. After all, the Type-C USB interface is not enough to support such a high bandwidth of HDMI. In addition to HDMI, there are also Type-C to VGA adapters on the market, which are suitable for projectors, so I won't go into details here.
Purchasing this type of product is like buying an HDMI cable. It still requires certain requirements for the interface and quality. Currently, the prices of such products on the market are basically above 100 yuan. Users try not to buy adapters with a price of below 100 yuan. In addition, it should be noted that from the perspective of the products on the market, the HDMI interfaces of this type of adapter all adopt the 1.4a specification. If you want to output 4K@60Hz, you need the Type-C interface to be further popularized.
—— I want full-featured extension Type-C dock
Market price: According to the function expansion prices vary, generally starting from 140 yuan
Applicable interface: Thunderbolt 3
Functional features: including HDMI output, USB interface, VGA output and network port
If you only think that one function expansion is too troublesome, then this type of Type-C dock on the market is the most suitable user who has purchased thin and light notebooks but only Type-C interface. Basically, the dock can design all the expandable functions according to the user's needs, including VGA, HDMI, network port, USB3.0 and other interfaces. Of course, the price of the dock is also different depending on the number of interfaces. For example, Dell's Type-C dock is relatively complete, with a price of around 300 yuan, while some docks have relatively single functions, and the price may be only below 200 yuan. Since docking stations like
can expand multiple devices at the same time, they take up a large bandwidth and can only be used on the Thunderbolt 3 ports of the Type-C interface. These docking stations can be used, including Apple's MacBook, Dell's new generation XPS, and HP's latest Spectre notebooks. However, it should be noted that some brands' proprietary docks can theoretically support all Thunderbolt 3 Type-C interfaces, but it is not ruled out that manufacturers themselves do some tricks in the product to limit their compatibility. This should be paid attention to when purchasing.
