USB-C to Ethernet Adapter with 100W PD Pass-Through - 1Gbps

In this review the StarTech USB-C to Ethernet Adapter is evaluated for users who need a reliable wired connection without sacrificing their single USB-C port. The review finds the adapter most compelling for laptop and tablet users who travel, work from cafes or manage fleets of machines because it adds 1Gbps Ethernet while allowing pass-through charging via its 100W PD port. Its Realtek chipset and broad OS support mean it is a practical, low-friction option for both modern and legacy systems where a stable wired connection and simultaneous charging are priorities.

Key Features

• 100W PD pass-through: Lets you connect a charger to the adapter so a laptop or tablet can charge while using a wired network connection.
• 1Gbps network speed: Adds full gigabit Ethernet over CAT5E for faster, more stable transfers compared with Wi-Fi on compatible networks.
• Broad compatibility: Auto-installs on Windows, MacOS, ChromeOS and Linux with support for Intel, AMD, ARM and Apple Silicon platforms.
• Realtek chipset with PXE/WoL: Supports PXE boot and Wake-on-LAN for IT provisioning and remote management tasks.
• Compact attached cable: A 6in attached USB-C cable keeps the adapter portable and ready for travel without extra cords.
• Multi-speed backwards support: Works with 10/100Mbps networks as well as 1Gbps, so it functions across older infrastructure.

Who It's For

This adapter is ideal for professionals who use MacBooks, Chromebooks or USB-C laptops with limited ports and who need a secure, consistent wired connection while keeping their charger connected. IT technicians and system administrators will also appreciate the PXE and WoL support when provisioning or maintaining fleets of devices.

Users who already have multiple USB-C ports or those who require multiport docking station features like additional USB-A, HDMI or SD readers should look elsewhere; this product focuses on adding Ethernet and pass-through charging rather than acting as a full hub or dock.

Pros & Cons

Pros

• Provides true 1Gbps wired connectivity for more reliable transfers than wireless.
• 100W PD pass-through preserves the original USB-C port for charging while you use Ethernet.
• Broad OS and chipset compatibility minimizes driver hassles across Windows, MacOS, ChromeOS and Linux.
• Supports PXE and Wake-on-LAN for remote system provisioning and management.

Cons

• Attached 6in cable limits placement flexibility compared with a separate or longer cable option.
• Does not replace a multiport dock; it provides Ethernet and charging pass-through only.
