## Summary description

Use it to adapt USB-C ports for compatible devices, docking setups, external monitors and high-bandwidth data or video transmission.

## Long description

Renkforce RF-3778880 is a compact USB-C adapter designed to provide a USB4 connection with one plug and one socket. The adapter supports high-bandwidth data transfer and video transmission up to 8K resolution, allowing it to connect compatible devices, external monitors or docking stations where a USB-C to USB-C passthrough is required. Its slim form factor makes it suitable for portable setups and temporary expansions of existing USB-C ports without adding bulk.
Advantages
The adapter offers a straightforward one-plug-to-one-socket design that preserves USB4 performance for video and data where supported by host and peripheral devices. It supports transmission of high-resolution video up to 8K and is suitable for workflows that require high bandwidth, such as multi-stream displays and large-file transfers. The simple construction reduces connection complexity and enables quick insertion and removal for mobile and desktop use.
Suitable for
 Connecting a USB-C laptop or docking station to a USB-C monitor that supports USB4 and 8K video
 Extending or adapting a USB-C port for temporary workstation setups
 High-bandwidth data transfer between compatible USB4 devices
 Integrating into video production or editing workflows that require high-resolution display output
Key specifications
 Interface type: USB-C plug to USB-C socket
 Standard supported: USB4 (backward compatible with USB-C standards where applicable)
 Maximum video support: up to 8K resolution (dependent on host and display capabilities)
 Primary use: data and video transmission at high bandwidth
 Physical form: compact inline adapter suitable for portable use
How to use
Insert the USB-C plug of the adapter into the host device’s USB-C port, then connect the device or cable to the adapter’s USB-C socket. Ensure that both the connected host and peripheral support USB4 video and bandwidth requirements for 8K output. If the host or display does not support the same bandwidth or video standards, the adapter will operate at the highest mutually supported mode. Avoid forcing connections; align the reversible USB-C plug and maintain a straight cable route to prevent strain on the connector.
Usage recommendations
For reliable 8K video and maximum data throughput, use high-quality USB-C cables and ensure both host and display firmware/drivers are up to date. Do not exceed the electrical or thermal limits of connected devices; if performance issues occur, verify cable ratings and try alternative ports or direct connections to isolate compatibility constraints.
