USB4 Cable StarTech 2m (20 Gbps) USB-C to USB-C, 240W PD EPR, DP 1.4 4K@120Hz, TPE Jacket, Black

The StarTech.com 2m USB4 cable provides a certified USB-C connection for data, video and power between compatible devices. It supports USB4 Gen 2x2 20Gbps data transfer, DisplayPort 1.4 Alternate Mode video up to 4K at 120Hz (with DSC and HDR10 support), and Extended Power Range Power Delivery up to 240W. Each connector is laser-etched with USB4 markings and the cable includes an integrated E‑marker for correct power negotiation. The cable has a 2 meter length, a TPE inner jacket with a braided exterior for flexibility and wear protection, and nickel-plated connectors rated for frequent use.

Advantages

This USB-IF Certified USB4 cable ensures spec-compliant performance for demanding workflows that combine high-bandwidth data, high-resolution video, and high-power charging. Certification and the E-marker chip reduce uncertainty about compatibility and enable stable charging up to 240W. The construction — shielded 23/31AWG wiring, TPE jacket with braided exterior, and nickel-plated connectors — improves signal integrity, EMI protection, durability and flexibility for everyday use.

Suitable for

• Connecting high-performance laptops (including Apple M-series Pro/Max) to docks or chargers
• Driving a single 4K 120Hz display or dual 4K 60Hz displays via DisplayPort 1.4 Alt Mode
• High-bandwidth data transfers up to 20Gbps between USB4 devices
• Powering and charging USB-C devices requiring up to 240W EPR Power Delivery

When it may not be suitable

This cable is designed specifically for USB4 Gen 2x2 applications; it may be more capable than required for basic charging or low-bandwidth peripherals. Devices that require USB4 Gen 3x2 (higher throughput) or proprietary power interfaces beyond USB PD 3.1 EPR are outside its intended use. Compatibility depends on connected devices and chargers supporting the same USB4, DP Alt Mode and EPR PD capabilities.

Key specifications

• Cable length: 2 m (6.6 ft)
• Connector type: USB-C to USB-C (straight male to straight male)
• Maximum data transfer rate: 20 Gbit/s (USB4 Gen 2x2)
• Video: DisplayPort 1.4 Alt Mode with DSC, HBR3 and HDR10; up to 4K @ 120Hz or dual 4K @ 60Hz
• Power Delivery: USB PD 3.1 Extended Power Range up to 240W
• Wire shielding and gauge: shielded 23/31 AWG conductors for EMI protection
• Jacket: TPE inner jacket with braided exterior
• Connector plating: nickel-plated contacts
• Colour: Black

How to use

Connect one USB-C end to a compatible USB4 host, docking station, or charger and the other end to a USB4-capable device. Ensure both connected devices and any intermediary dock or charger support the required USB4 Gen 2x2 data rate, DisplayPort Alt Mode and EPR Power Delivery if you need 20Gbps throughput, 4K 120Hz video or 240W charging. The integrated E‑marker will negotiate safe power delivery automatically when paired with a compatible power source. Handle the cable by its connectors and avoid sharp bends to preserve the jacket and internal wiring.

What to consider before purchase

• Verify that your host device, display or dock supports USB4 Gen 2x2, DP 1.4 Alt Mode and PD 3.1 EPR if you require full performance
• Confirm the charger or dock can supply up to 240W EPR Power Delivery for high-power laptops
• For higher-than-20Gbps throughput requirements, check whether a different USB4 generation or interface is needed
• Ensure a 2 m length suits your workspace; longer or shorter cables may be preferable in some setups

Usage recommendations

Use this certified USB4 USB-C cable with compatible docks, chargers and devices to ensure expected data rates, video output and safe high-power charging; avoid excessive twisting or tight kinks and store coiled loosely to extend cable life.
