Overview

The Pubiohs 5GB USB Ethernet Adapter is a compact USB dongle that adds a 5Gbps wired network port to any device with USB-A or USB-C. With a maximum data rate of 5,000Mbps, it delivers roughly five times the speed of standard gigabit Ethernet, making it ideal for bandwidth-intensive tasks like large file transfers, 4K/8K streaming, and lag-sensitive online meetings or gaming.
Built with an aluminum alloy chassis that doubles as a heatsink, the adapter stays cool under sustained load and prevents thermal throttling. It weighs just 30 grams, so it slips easily into a laptop bag. Plug-and-play support covers Windows 10/11, macOS, iPadOS, Linux, and Chrome OS; older systems may need a one-time driver installation.

Connectivity & Compatibility

The adapter features a dual-port design with both USB-C and USB-A connectors permanently attached. This lets you plug it into the latest MacBooks, Dell XPS, Surface, iPad Pro, and recent iPhones (17/16/15 series), as well as legacy laptops with standard USB-A ports — no separate cable or dongle required.

  • Supported OS: Windows 10/11, macOS, iPadOS, Linux, Chrome OS
  • Standards: IEEE 802.3, 802.3u, 802.3ab (2500/5000Mbps)
  • Interfaces: USB-A male, USB-C male, RJ45 female
  • Backward compatible: 10/100/1000/2500Mbps
    Important caveats: This adapter does not work with game consoles like Nintendo Switch or Wii. To achieve full 5Gbps speed, you need a broadband plan offering at least 5Gbps, a router with 5Gbps output ports, a Cat6a or Cat7 Ethernet cable, and a device with a USB 3.2 Gen 2 (or newer) port (often labeled SS10).

Product Info

The Pubiohs 5GB USB Ethernet Adapter is positioned as an entry-to-mid-tier networking accessory, available on online retailers for around ¥12,000 (~$80). It comes with the adapter unit only — no printed driver disc or carrying case. Warranty is typically one year (check the product listing for exact terms). In the current market, 5Gbps USB LAN adapters are still uncommon, and this model offers a relatively affordable way to upgrade beyond gigabit speeds without opening your laptop.

Best Use Cases

  • Creative professionals and remote workers who frequently upload/download large files. The 5Gbps pipe provides lower latency and higher throughput than Wi-Fi, making cloud syncing, video editing asset transfers, and remote desktop work smoother.
  • Online gamers who demand a stable, low-latency wired connection. While the adapter itself supports 5Gbps, the actual benefit depends on your internet service plan. Even with a 1Gbps plan, the wired stability alone can reduce lag spikes compared to Wi-Fi.
  • Ultrabook and tablet users who lack any built-in Ethernet port. With both USB-C and USB-A connectors built in, you can share the adapter between a modern MacBook and an older Windows laptop without carrying extra cables.
  • Not recommended for users with sub-gigabit internet who only have USB 3.0 or older ports — a simple gigabit USB adapter would be more cost-effective.
