Compact black USB-C to RJ45 adapter with short folding pigtail cable

Cable Matters 201393-BLK USB-C to Gigabit Ethernet Adapter

SKU CH-QA3Y-PGMQP

Adds a gigabit RJ45 port to USB-C devices with a foldable 2-inch pigtail and 5 Gbps USB 3.2 speed

  • Gigabit Ethernet for faster, more secure wired connections
  • Foldable pigtail cable retracts for compact portability
  • Plug-and-play operation with no external drivers required
  • Broad compatibility across Mac, Windows, Linux and Chrome OS
  • Supports Wake-on-LAN, full/half duplex and auto MDIX

Portable USB-C Gigabit Adapter

The Cable Matters 201393-BLK adds a wired RJ45 network port to laptops and tablets that only have USB-C. It suits mobile professionals who need a stable connection in hotels, offices or Wi-Fi dead zones. The foldable pigtail retracts into the body for pocket-sized transport. No external drivers are required on Chrome OS, Linux, Mac OS or Windows.

Gigabit Over USB 3.2

The adapter runs at 1000 Mbps through a USB 3.2 link rated at 5 Gbps, so the Ethernet link is never bottlenecked by the host interface. It falls back to 10 and 100 Mbps on older switches without configuration. Supported standards include 10BASE-T, 100BASE-TX and 1000BASE-T with full-duplex, half-duplex, auto MDIX and IPv4/IPv6. Wake-on-LAN and backpressure flow control are also implemented.

Upgrade From Wireless Or Missing Port

This replaces a missing onboard Ethernet jack or an unreliable Wi-Fi link when latency, security or raw throughput matter. The jump is worth it for large file transfers, video streaming or firmware updates that stall on wireless. It is not for buyers who need multi-gigabit speeds beyond 1 Gbps or a second simultaneous network interface.

Questions about this item

Which version of the Cable Matters 201393-BLK should I choose for a Thunderbolt 4 laptop?

The single model 201393-BLK is compatible with Thunderbolt 4, USB4, USB 3.2 and earlier USB-C ports, so no separate version selection is needed.

What does the 1000 Mbps rating deliver when the adapter is plugged into a real machine?

It provides a wired Gigabit Ethernet link at 1000 Mbps full-duplex, limited by the USB 3.2 5 Gbps upstream connection and the 10/100/1000BASE-T network you plug into.

How does the USB 3.2 interface affect the maximum throughput of this Gigabit Ethernet adapter?

The USB 3.2 Gen 1 link runs at 5 Gbps, which is well above the 1 Gbps Ethernet rate, so the Ethernet port — not the USB bus — sets the practical ceiling.
