Renkforce USB4 USB-C Adapter RF-3795558, 1x female USB-C to 1x female USB-C, supports 8K

The Renkforce USB4 USB-C Adapter RF-3795558 is a female-to-female USB-C coupler designed to join or extend USB-C connections between devices and cables. Specified for the USB4 standard with support for 8K video passthrough, this adapter allows compatible hosts, monitors and peripherals to transmit high-resolution video and high-speed data through a simple inline connection. It is compact and passive, intended for situations where two USB-C cables must be linked without altering device settings or introducing active signal conversion.

Advantages

This USB-C adapter supports USB4 capabilities including high-bandwidth data and 8K video passthrough when used with compatible cables and devices. Its female-to-female configuration provides a quick and reversible way to extend cable length or connect devices with accessible USB-C ports. The compact design minimizes additional bulk and is suitable for use on desks or in AV setups where a short, neat coupling is preferred. Because it is passive, it does not require power or drivers for basic passthrough functions.

Suitable for

• Extending USB-C cable runs between a computer and a monitor or docking station
• Linking two USB-C cables to reach a device when a single cable is too short
• Connecting USB-C peripherals in home or office AV setups supporting USB4
• Temporary or semi-permanent inline coupling in testing and installation workflows

Key specifications

• Connector type: 1× USB-C female to 1× USB-C female
• Standard support: USB4 specification with 8K video passthrough capability (dependent on connected devices and cables)
• Function: Passive coupler for video and data passthrough
• Form factor: Compact inline adapter suitable for desktop and AV installations

How to use

To use the adapter, insert the male USB-C plugs of two compatible cables into the adapter’s female ports, ensuring secure seating. Connect one cable to the host device (for example a laptop or dock) and the other to the target device (such as a monitor or peripheral). Confirm that connected cables and devices support USB4 and the required video/data profiles to achieve 8K output. No driver installation is required for passthrough; if a device does not recognize signals, check cable compatibility and port capabilities.

Usage recommendations

For reliable 8K video and full USB4 bandwidth, use high-quality cables rated for USB4 or the equivalent certified specifications and ensure both devices expose USB4-capable ports. Avoid stacking multiple passive adapters or very long cable chains that may degrade signal integrity; for long runs or active signal needs consider using certified active cables or signal extenders.
