Does it work with a USB-C laptop?

Only through a USB-C to USB-A adapter, since the hub itself has a USB-A plug. USB-C-only MacBooks and ultrabooks need that adapter.

Does it need a power adapter?

No. It draws power from the host USB port, which is enough for keyboards, mice, flash drives and most external drives.

What Ethernet speeds does it support?

It supports 10/100/1000 Mbps and negotiates automatically with the router or switch. Real throughput depends on your network and cable.

Is it compatible with Mac and Windows?

Yes. It works with Windows XP through 10, macOS 9.x and 10.x, and Linux. Newer macOS versions generally work too, though very old drivers may need a manual install.

Can I use all three USB ports and Ethernet at the same time?

Yes, all four ports work simultaneously. The three USB 3.0 ports share the host link's bandwidth, so heavy simultaneous transfers will be slower than one at a time.

The hub itself. No power supply or USB-C adapter is included, so check your laptop's ports before buying.

Our take on the 3-Port USB 3.0 Hub with Gigabit Ethernet

This is a compact aluminum-style adapter that adds three USB 3.0 ports and one RJ45 gigabit Ethernet port to a laptop or desktop through a single USB-A connection. The Ethernet side runs full 10/100/1000 Mbps, which is far more stable than Wi-Fi for large transfers, video calls and gaming. The three USB ports each carry 5 Gbps, enough for external drives, flash drives and peripherals. It suits MacBook Air, Surface and ultrabook owners who lack a wired port, and it competes with brand-name hubs on port count and price rather than on extras like USB-C, card readers or power delivery.

What reviewers say

Owners generally find it a simple, reliable way to get wired internet and extra USB ports from one small hub. Most praise the stable gigabit connection and plug-and-play setup on Windows and Mac. A few mention that heavy simultaneous USB use slows transfers and that the plastic shell feels light.

What people mention
