2.5 Gigabit Ethernet Adapter with Universal USB Connectivity

The Plugable USBC-E2500 delivers 2.5Gbps network performance through a hybrid USB-C/USB-A connection. Built with the Realtek RTL8156B chipset, this adapter more than doubles traditional Gigabit Ethernet speeds when paired with 2.5Gbps-capable switches and routers.

Hybrid 2-in-1 Cable Design

The included convertible cable switches between USB-C and USB-A connections, eliminating compatibility concerns across different devices. Connect to laptops, desktops, tablets, or iPhone 15 models without additional adapters. USB 3.0 or higher required for full 2.5Gbps performance; USB 2.0 systems limited to 480Mbps.

Works with Existing Cat 5e Infrastructure

Upgrade your network speed without replacing cables. 2.5 Gigabit Ethernet signals transmit over standard Cat 5e cabling, reducing infrastructure costs while delivering speeds up to 2.37Gbps in lab testing using iPerf. Actual performance depends on your internet service provider, network equipment, cable quality, and host system capabilities.

Cross-Platform Driver Support

Built-in drivers for Windows 11, 10, 8.x, 7, macOS 10.7+, Linux kernel 3.2+, Chrome OS, and iPhone 15 with iOS 17+. Legacy macOS 10.15 and older requires driver download with limited functionality (1Gbps link rate, no jumbo frame support) until updated. Compatible with USB-C (5Gbps), USB 3.0, Thunderbolt 3, and Thunderbolt 4 systems.

Common Applications

• Add wired 2.5 Gigabit network to devices without Ethernet ports
