Conceptronic ETTA04B20 USB 4.0 Gen 3 C-C PD 3.1 240W Cable 2M, 48V 5A, 40Gbps, E-Mark

The Conceptronic USB 4.0 Cable ETTA04B20 is a 2 m USB-C to USB-C cable designed for high-speed data transfer and high-power charging. It supports USB4 Gen 3x2 with up to 40 Gbps bandwidth and Power Delivery 3.1 via an E-Mark chipset, allowing safe power delivery up to 240W (48V/5A). The cable is black, braided for durability and built to be compatible with USB 3.2, USB 2.0 and Thunderbolt 3 devices while supporting display output up to 8K at 60Hz.

Advantages

The cable combines USB4 high-bandwidth data transfer with PD 3.1 power delivery and an E-Mark chip for reliable negotiation and safety. Its braided exterior improves resistance to wear and bending, and the USB-C connectors on both ends provide reversible, universal connectivity. Backward compatibility with earlier USB standards and Thunderbolt 3 ensures broad device support, and support for 8K@60Hz enables high-resolution video output.

Suitable for

• High-speed data transfer between computers and storage devices
• Powering and charging laptops, monitors and other devices that accept up to 240W PD
• Connecting USB-C monitors or docks with video output up to 8K@60Hz
• Use with Thunderbolt 3 compatible devices (backward compatibility)

How to use

Connect one USB-C end to a compatible host device (laptop, desktop, dock or charger) and the other end to the target device (monitor, external drive or laptop). Ensure both connected devices support the required USB version and Power Delivery profile—devices negotiate power via the E‑Mark chipset. For high-resolution video, connect to a display or dock that supports USB-C video input and set the display settings on your host system as needed.

Recommendations

Use the cable in environments free of extreme bending or crushing; avoid repeated sharp kinks. For maximum power delivery and data performance, connect to PD 3.1 compliant chargers and USB4-capable hosts. If you need longer-term durability in high-mobility scenarios, inspect connectors periodically and replace the cable if visible wear appears.
