ACT USB4® 20Gbps cable, USB-C, USB-IF certified, 1 meter

The ACT USB4 20Gbps cable (AC7431) is an official USB-IF certified USB-C cable designed for data, power and video over a single connector. It supports USB4 Gen 2x2 with up to 20 Gbps data transfer, carries up to 240W using the Extended Power Range (EPR) 48V profile, and supports DisplayPort Alternate Mode for video output. The 1 m black cable is backward compatible with Thunderbolt 3, USB 3.2 and USB 2.0 and includes an e-marker chip to communicate capabilities with connected devices.

Advantages

The cable is USB-IF certified and tested to official standards, and the connector bears the USB-IF logo. Integrated e-marker intelligence negotiates supported features with host devices and chargers. With USB4 20Gbps throughput and EPR 240W power delivery the cable combines fast data transfer, high-power charging and video transmission in one USB-C cable. Magnetic shielding and a 1 m length make it suitable for typical workstation and mobile use while maintaining signal integrity.

Suitable for

• Connecting laptops and docks that require USB4 / Thunderbolt 3 compatibility
• High-speed data transfer between compatible devices (up to 20 Gbps)
• Charging high-power laptops and devices using up to 240W (EPR 48V)
• Video output via DisplayPort Alt Mode — one 5K@60Hz display or two 4K@60Hz displays in daisy chain

How to use

Plug one USB-C connector into a compatible host or charger and the other into a compatible device or display. The e-marker chip negotiates supported data, power and video capabilities automatically; ensure both connected devices support the desired functions (USB4/Thunderbolt, EPR power profiles, DP Alt Mode). For multi-monitor daisy chaining, connect displays that support DisplayPort MST and set the monitor chain according to the display manufacturer’s instructions.

Recommendations

Use the cable with devices and chargers that explicitly support USB4 or Thunderbolt 3 and EPR power profiles to achieve the specified 20 Gbps data rate and 240W charging. Avoid sharp bends and excessive pulling; replace the cable if the connector or insulation is damaged.
