About this deal
USB-C to USB-C cable with only power supply: This kind of cable is used to connect the adapter to device, or computer to device, such as lamps, toys, measuring tools, etc. which without data requirements. But this does not mean that there are only VBUS and Ground wires inside the USB cable. There must be a CC wire here. The CC wire is responsible for communicating with the adapter charging protocol, otherwise the cable will not be able to charge normally. Compared with Thunderbolt 3, Thunderbolt 4 has no changes in physical appearance and maximum speed. The same is the design of the USB-C interface and the maximum bandwidth of 40Gbps, but it has been optimized in some aspects, such as bandwidth allocation
USB 3.0 USB-C to USB-C cable : This is a non-standard USB C cable , the USB Association does not contain this specification, but some of our customers still require us to provide this specification for their hard drive products Thunderbolt 4 has higher specifications, more functions, and stronger compatibility, but Thunderbolt 4 requires Intel's certification and authorization, there is an additional cost. Compared with Thunderbolt 4, USB4 has no excessive requirements and is more versatile. So in the future, Thunderbolt 4 and USB4 will definitely complement each other and co-exist. As more and more interfaces are uniformly stipulated to use the USB-C interface, other interfaces will gradually be replaced, such as: Micro, Type B, Thunderbolt, HDMI, DC.For the full-featured GEN 2 USB-C to USB-C cable , the PIN point of its connector PCB board is very compact , it cannot be welded by hand, an expensive automatic welding machine must be used. This is why many USB cable factories cannot produce USB 3.1 GEN 2 USB-C to USB-C cable
Starting from USB 3.1 GEN 2 USB-C to USB-C cable , the connector is only for T ype- C, other connectors are no longer applicable, including T ype- A, T ype- B, M icro , M ini Standard USB-C to USB-C cable : This is the most common mobile phone charging cable, the original mobile phone charging cable is this, can charge and small data transmission (480Mbps Max)USB4 USB-C to USB-C cable : USB4 can provide up to 20Gbps and 40Gbps two speeds, P-Shine has begun mass production of USB4 cables Are all USB-C to USB-C cable the same? No, not all USB-C cables are equal. USB-C stands for the shape and type of connector, which is the same for all USB-C cables but not all cables support the same kind of protocols and transfer speeds. USB 3.2 USB-C to USB-C cable : USB 3.2 c an provide up to 20Gbps transfer speed, which is twice the USB 3.1 GEN 2 cable. At present, there are not many products that can use USB 3.2 cable on the market. It may be a transitional product between USB 3.1 and USB4.
