What it is and who it's for
The Fervit 2-in-1 AR Glass Adapter is a 3.94 inch USB-C splitter that adds a video output and a Power Delivery charging port to a single host connection. It targets owners of AR glasses, a Steam Deck, ROG Ally or Nintendo Switch who need simultaneous display output and charging from one USB-C port. The white cable supports USB 2.0 data at 480Mbps and 8K video at 60Hz. It is not for users whose host lacks USB-C video output or who need more than one video stream.
How it fits into a build
Plug the male USB-C connector into the host, then attach the monitor or AR glasses to the video female port and wait for the image to appear before connecting a PD charger to the power female port; the sequence cannot be swapped. The adapter draws up to 100W PD pass-through so the host charges while driving an external display. It generates noticeable heat during Switch TV mode and requires a 60W PD source, so keep it in open air rather than a tight cable channel. OTG data at 480Mbps remains available alongside video and charging.
What it replaces and when to upgrade
This splitter replaces a basic USB-C hub that cannot deliver enough power for Switch TV mode or ROG Ally 30W enhanced mode, and it solves monitors that fail to supply adequate power on their own. The jump is worth it when AR glasses refuse to enter TV mode on a Switch, when a handheld's high-performance mode stays locked, or when a single USB-C port must carry 8K 60Hz video, 480Mbps data and 100W charging simultaneously.
