Fervit Transparent USB-C Female to Female Adapter USB4.0 40Gbps 140W LED Display

SKU CH-AE24-9A8QC

A transparent USB-C female-to-female adapter delivering 40 Gbps data, 140 W power, and real-time voltage, current and power readout on an LED display

  • 8K@60Hz video on USB-C monitors via DP Alternate Mode
  • Transparent reversible USB-C housing shows internal layout
  • 40Gbps USB4.0 bandwidth for large-file transfers
  • 140W Power Delivery charges laptops while connected
  • Real-time LED readout of volts, amps and watts

Transparent USB4 adapter with live power display

The Fervit adapter connects a USB4 host to a USB-C monitor that supports DisplayPort Alternate Mode. It delivers up to 40Gbps data transfer and up to 140W power delivery. A built-in LED screen shows voltage, current and power in real time.

8K video users and power monitors

This adapter suits users who need a single 8K@60Hz, 5K@60Hz or 4K@60Hz external display and want to watch charging metrics live. It is not for buyers whose monitor lacks a USB-C port with DisplayPort Alternate Mode. It is also not for setups that require more than one video output from a single port.

USB4 40Gbps and 140W PD spec

The decisive specification is the USB4.0 40Gbps data rate combined with 140W Power Delivery at 28V/5A. If your host and cable support USB4 and your display accepts DP Alternate Mode over USB-C, this adapter will pass full bandwidth and charging. If either link is limited to a lower USB generation, the adapter will fall back to that speed and power level.

Questions about this item

Will 40 Gbps data transfer hold steady during long file moves?

The adapter is rated for USB4.0 40 Gbps, so sustained throughput depends on the host controller and cable quality rather than the adapter itself.

Does the LED display or the 140 W power path create noticeable heat or noise?

No fan or moving parts are present; the unit is a passive adapter with an LED readout, so it runs silently and any warmth comes only from the power being delivered.

What must my host port and monitor port both support for video and 140 W charging to work?

The host needs a USB4 or USB 3.1 Type‑C port with DisplayPort Alternate Mode and Power Delivery up to 140 W; the monitor must accept DP Alternate Mode over its Type‑C input.
