USB-C to USB-C cable REMAX RC-C039, USB4.0, 1 m, 240W, black

REMAX RC-C039 is a 1 m USB-C to USB-C cable designed to support the USB4.0 specification and high-power delivery up to 240W. The cable combines high-speed data transfer, video signal transmission and PD charging in a single connector-to-connector solution. Constructed with reinforced connectors and an aluminum alloy shell on both ends, the RC-C039 is intended for dependable daily and professional use with laptops, monitors, docking stations and high-power chargers.

Advantages

The RC-C039 provides data transfer rates up to 40 Gbps and supports video transmission compatible with USB4.0-enabled devices, enabling single-cable connections for displays and peripherals. With up to 240W power delivery (48 V, 5 A) the cable supports fast charging of high-power laptops and devices. An integrated E‑Mark chip manages power negotiation to ensure stable and safe charging, while the 1 m length balances ease of use and workspace flexibility. Durable connector shells and quality materials improve longevity and resistance to wear.

How to use

Connect one USB-C end of the REMAX RC-C039 to a compatible host device (laptop, docking station or charger) and the other end to the target device (laptop, monitor, external drive or phone). The cable is plug-and-play for data and video transmission when used with USB4-capable devices and operating systems that support USB4/USB‑C protocols. For optimal charging, use with chargers and devices that support USB Power Delivery and the required voltage/current profile. Observe connector orientation and insert the plug fully to ensure proper contact.

Usage recommendations

Use the cable with compatible USB4-capable devices and certified chargers to achieve the listed 240W power delivery and 40 Gbps data rates. Avoid sharp bends near the connector ends and disconnect by gripping the connector shell rather than pulling the cable. Store the cable loosely coiled and keep connectors free of debris. If a device does not negotiate high-power PD levels, check device and charger compatibility and firmware updates.
