USB-C to USB-C cable UGREEN USB4 Gen 3 240W 40Gbps 1m (star gray)

UGREEN USB-C to USB-C cable USB4 Gen 3 (1 m, star gray) is a high-performance connection cable with USB-C connectors on both ends. It supports USB4 Gen 3 protocol for combined power, data and video transmission over a single cable. With a one-metre length and reinforced construction, the cable is intended for everyday use when charging compatible laptops, connecting docking stations, external SSDs and displays that require high bandwidth and high power delivery.

Advantages

The cable supports up to 240W power delivery, enabling fast charging of high-power laptops and other USB-C PD devices. Data throughput reaches up to 40 Gbps, suitable for large file transfers and high-resolution video streams. The USB4 Gen 3 specification ensures compatibility with USB-C devices that use tunnelling for DisplayPort and PCIe, while the robust outer jacket and strain relief improve durability and reduce wear from repeated plugging. The one-metre length balances reach and reduced signal loss for stable performance.

Suitable for

• Charging high-power laptops and USB-C PD notebooks up to 240W
• Connecting USB-C docking stations and hubs to hosts
• Transferring large files between computers and external SSDs at up to 40 Gbps
• Connecting monitors and transporting video signals via USB4 tunnelling (DisplayPort/Alt Mode capable devices)
• Portable workstations and home office setups requiring a single-cable solution for power, data and video

Key specifications

• Connector type: USB-C to USB-C
• Protocol support: USB4 Gen 3
• Maximum power delivery: up to 240W
• Maximum data transfer rate: up to 40 Gbps
• Cable length: 1 metre
• Color: star gray

How to use

Connect one end of the cable to the USB-C port of the host device and the other end to the target device such as a laptop, docking station, external SSD or monitor. When used for charging, ensure both devices support the negotiated power level; the cable will carry up to 240W when both endpoints negotiate PD at that level. For high-speed data transfers and video, use ports that support USB4 or compatible USB-C Alt Mode/DisplayPort and follow the device manufacturer's guidance for cable orientation and port selection. Avoid forcing connectors and insert fully until a secure connection is made.

Usage recommendations

To maintain performance and safety, use the cable with devices and chargers that support the required USB4 and power delivery specifications. Avoid bending the cable sharply near the connectors, keep it away from heat sources, and inspect periodically for wear. For optimal video and data performance, connect directly between devices or via certified docks that support USB4 Gen 3 bandwidth.
