With years of industry experience and expertise, our USB4 cables are made from the finest materials to ensure durability and longevity. These cables undergo thorough testing to ensure lightning-fast speeds up to 40 Gbps. With our cables, you're not merely purchasing a product; you're investing in a solution that boosts connectivity and productivity.
Our USB4 is compatible with the latest USB Power Delivery (USB-PD) 3.1 standard, which increases the voltage to 48V and maintains a maximum current of 5A, which can provide up to 240W of power.
2. Versatility
Increased power delivery supports a wider range of devices, reducing the need for proprietary power adapters and simplifying charging setup, capable of powering high-performance laptops, gaming gear, and other power-hungry electronics.
Some USB4 devices can achieve the full 40 Gbps speed, which is equivalent to Thunderbolt 3 & allows for extremely fast data transfers and high-resolution video output.
USB4 can tunnel DisplayPort to transmit high-resolution video through USB4 ports, supporting external monitors, projectors, and display devices.
8K 60HZ
USB4 supports resolutions up to 8K and transmits video signals at a refresh rate of 60Hz. It can transmit extremely high-definition video for high-end display devices and professional visual applications.
4K 60HZ
USB4 supports the transmission of 4K resolution video at a refresh rate of 60Hz. This is currently the more common high-definition video standard and is widely used in a variety of occasions such as TVs, monitors and games.

1.What is USB4, and how does it differ from previous USB versions?
USB4 is the latest USB standard, offering improved data transfer speeds (up to 40 Gbps), enhanced compatibility, and the ability to tunnel other data protocols like DisplayPort and PCI Express. It's faster and more versatile than USB 3.X.
2.How fast is USB4 compared to USB 3.2?
USB4 can transfer data at up to 40 Gbps, which is double the maximum speed of USB 3.2 Gen 2x2 (20 Gbps) and significantly faster than earlier USB 3.X versions.
3.Is USB4 backward compatible with older USB standards?
Yes, USB4 is backward compatible with USB 3.2, USB 2.0, and Thunderbolt 3 devices, allowing it to work seamlessly with a variety of older devices.
4.Does USB4 require a special cable to reach 40 Gbps speeds?
Yes, USB4 requires certified USB-C cables designed to handle the higher speeds. Make sure to use cables labeled for USB4 or Thunderbolt 3/4 to achieve 40 Gbps speeds.
5.Does USB4 provide sufficient power to charge laptops and other high-powered devices?
Yes, USB4 supports USB Power Delivery (USB-PD) and can deliver up to 100W of power, sufficient to charge most laptops, tablets, and other high-powered devices.
6.What display capabilities does USB4 offer?
USB4 supports tunneling of DisplayPort, enabling connections to high-resolution monitors. It can handle a single 8K display or two 4K displays.
7.Is USB4 secure against data vulnerabilities?
USB4 includes optional support for security features like Direct Memory Access (DMA) protection, which helps prevent unauthorized access to connected devices.
8.Does USB4 support daisy-chaining multiple devices?
Yes, USB4 supports daisy-chaining but depends on the specific implementation. It allows several devices to connect to a single port in sequence.
9.How does USB4 compare to Thunderbolt 4?
USB4 and Thunderbolt 4 both offer 40 Gbps speeds, but Thunderbolt 4 has stricter requirements, such as guaranteed PCIe bandwidth, dual 4K display support, and enhanced security. USB4 is more flexible in its specifications.
10.Are there any drawbacks to USB4?
One potential drawback is that not all USB4 implementations provide the full 40 Gbps speed, as 20 Gbps is the base speed. Additionally, USB4 requires compatible USB-C cables to achieve its maximum potential.
