LUOM ULC28 USB-C Hub with Gigabit Ethernet

The LUOM ULC28 adds three USB 3.0 ports and a Gigabit Ethernet jack to any USB-C laptop or tablet. It draws power from the host port so no external supply is required. The aluminium housing helps dissipate heat during sustained transfers. This adapter suits mobile workers who need wired networking and extra peripherals on the move.

Practical limits of USB 3.1 and Gigabit Ethernet

The three USB-A ports share a single 5 Gbps USB 3.1 uplink so simultaneous heavy transfers will divide that bandwidth. The RJ45 port negotiates at 10, 100 or 1000 Mbps but actual throughput depends on the host controller and cable quality. No driver is needed for Windows 7 through 10, macOS or Windows Vista, yet the hub cannot supply more current than the host port allows.

Single specification that decides fit

The host must provide a USB-C receptacle that carries USB 3.1 data lanes; a USB-C port limited to USB 2.0 or power-only will not enable the Gigabit link or 5 Gbps hub speed. Buyers whose laptops lack a full-featured USB-C port cannot use this adapter for its intended network and hub functions.

Questions about this item

How do I decide between the single ULC28 model and any other version?

The ULC28 is the only model listed; it combines three USB 3.0 ports and one Gigabit Ethernet port in a silver aluminium housing, so there are no alternative capacities or versions to compare.

What real-world network speed does the 1000 Mbps Ethernet port deliver when connected to a laptop?

The RJ45 port negotiates at 10, 100 or 1000 Mbps, so actual throughput will match the speed of the switch or router you plug into, up to the full Gigabit rate.

Which USB standard limits the three USB-A ports to 5 Gbps, and what does that cap mean for attached drives?

The hub uses USB 3.1 signalling at 5 Gbps, so each USB 3.0 port can transfer up to that rate, while USB 2.0 devices fall back to their lower speed.
