USB-C Gigabit Ethernet with 100W PD 3.0

This adapter adds a 10/100/1000Base-T port and a USB-C power delivery input to laptops or tablets that lack wired networking. It targets mobile professionals who need a stable wired link while keeping their device charged through a single cable.

Sustained throughput on twisted pair

The Gigabit Ethernet port negotiates at 10, 100 or 1000 Mbps and maintains that rate over long transfers without thermal throttling. Auto crossover detection keeps the link up when cables are swapped, and plug-and-play operation means the connection stays live across reboots.

USB-C PD 3.0 charging ceiling

The USB-C female port accepts up to 100W of power delivery under the PD 3.0 specification, passing charge through to the host while the adapter draws its own modest operating power. Devices that require more than 100W or use a different charging protocol cannot be powered through this adapter.

Questions about this item

Does the USB-C 100W Power Delivery 3.0 port generate noticeable heat when the adapter runs all day?

The adapter draws power through its USB-C PD 3.0 port to charge the host while the Gigabit Ethernet link operates at 10/100/1000Base-T speeds, and its compact aluminium housing dissipates heat passively during continuous use.

What must my laptop already have for this adapter to work?

Your device needs a USB-C port that supports data and Power Delivery input; the adapter then provides a Gigabit Ethernet twisted-pair jack and a pass-through USB-C charging port.

Will the 10/100/1000Base-T port negotiate correctly with my older 100 Mbps switch?

Yes, the Ethernet port auto-negotiates down to 10 or 100 Mbps full-duplex on legacy twisted-pair cabling while still delivering 100W PD 3.0 charging to the host.
