EFB-Elektronik USB-C to RJ45 2.5 Gigabit Network Adapter
2.5GbE RJ45USB-C (USB 3.2)0.15 m cableBus powered
The EFB-Elektronik EBUSBC-RJ45-2500MBIT is a USB 3.2 network adapter with a USB-C plug and an RJ45 socket on a short 0.15 m cable, adding a 2.5 Gigabit wired Ethernet port to laptops, tablets and mini PCs with USB-C.
It auto-negotiates 2.5 Gbps, 1 Gbps, 100 Mbps and 10 Mbps in full duplex, supports Wake-on-LAN and automatic crossover detection, and is powered entirely from the USB port.
Before you order: EFB's published OS list covers Windows XP to Windows 10 and Mac OS X 10.6 to 10.12. For Windows 11, current macOS or Linux, ask us to confirm before ordering.
What's in the Box
- 1x EFB-Elektronik USB-C to RJ45 2.5 Gigabit adapter with integrated 0.15 m cable
- No network cable included
What It Means in Practice
- On a 2.5GbE switch or NAS, file transfers run up to 2.5x faster than on a Gigabit adapter.
- A short flexible cable keeps strain off the laptop's USB-C port compared with rigid dongles.
- Hot-swappable and bus powered — plug in and go, no power supply.
- Automatic crossover detection means any standard patch cable works, straight or crossed.
What Will Not Work
- It will not connect to USB-A ports without a separate adapter.
- It will not exceed 1 Gb/s on a Gigabit-only switch or router port.
- Windows 11 and Linux are not in EFB's published OS list — check with us first.
- PXE boot and MAC address pass-through are not listed by EFB.

Frequently Asked Questions
Singular Expert Insight · Buyer's Guide
This EFB adapter is a compact way to give a USB-C laptop a 2.5GbE wired port, with a short cable that is kind to the port. Check the OS list against your laptop first, and make sure the switch side is 2.5GbE — we can supply one of our 2.5GbE switches if needed.
✓ Buy it if you need a 2.5GbE wired port on a USB-C laptop running a supported OS.
✕ Skip it if you need PXE boot, MAC pass-through or Windows 11/Linux certainty.
