USB-C 4K HDMI Ethernet Adapter

The JCA351 adds a 4K HDMI output, a Gigabit Ethernet port and a USB-C pass-through charging port to laptops that only have USB-C sockets. It works with MacBook Pro, MacBook Air, Chromebook, Surface Pro, iPad Pro and other USB-C hosts. No driver installation is required for basic operation.

Sustained workload behaviour

The adapter maintains a stable 4K video signal and continuous Gigabit network throughput during extended sessions. Power delivery of up to 100 W keeps the host laptop charged while both the display and the wired network link remain active. Plug-and-play operation avoids software overhead that could interrupt long-running tasks.

Thermals noise and power

The unit draws power from the host USB-C bus and the connected charger to supply up to 100 W downstream. It runs silently with no moving parts and stays within normal operating temperatures for a compact USB-C hub under typical office or home workloads.

Questions about this item

Does the JCA351 adapter get hot or draw extra power when driving a 4K monitor and Gigabit Ethernet all day?

The adapter runs from the host USB-C port and passes up to 100 W through its PD 3.0 charging port, so sustained 4K output and network traffic add only modest load to the laptop's own power budget.

What must my laptop already provide for the JCA351 to deliver 4K HDMI, Gigabit Ethernet and 100 W pass-through charging?

The host needs a USB-C port that supports DisplayPort Alt Mode for video and USB Power Delivery 3.0 for the 100 W charging path; without both, video or charging will not work.

Will the JCA351 work with an older USB-A laptop if I use a USB-A to USB-C cable?

No, the adapter requires a native USB-C port with DisplayPort Alt Mode and PD 3.0; a simple USB-A to USB-C cable cannot supply the video or 100 W charging signals.
