Our take
CASA Hub i4 suits a USB-C host with video support when HDMI at up to 4K/30Hz, one USB-A data port, USB-C input and audio cover the need. Its 60W/100W input conflict and unmapped ASIN make power and offer verification essential.
A USB-C laptop or tablet user who needs a single HDMI display, one USB-A peripheral, audio and a charger input, and can check host video support and the current SKU's power rating..
Skip it if you require 4K/60Hz, confirmed 100W delivered to a laptop, multiple USB 3.x data ports, or an exact match to ASIN B07XDDJ77N.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor

- The indexed manual details HDMI, USB-A, USB-C/PD and 3.5mm audio functions.
- HDMI up to 4K/30Hz and the USB port speeds are stated.
What to weigh up
- The 60W reseller/title and 100W manual PD input claims conflict.
- The host USB-C port must support video output.
- The historical Amazon ASIN is not mapped to the SKU.

Full review: how the features affect your choice
What the features mean for you
A small four-function adapter for a specific host port
CASA Hub i4 combines a display output, a USB-A connection, charging pass-through and a headphone jack around a USB-C host. That mix targets a tablet or laptop with a compatible USB-C port where those four functions solve a real connection problem. The model is named in retailer records under SKU AAPADHUBI4GY, so this review can distinguish it from generic four-in-one adapters. It is still important to confirm that the selected Amazon offer shows the same i4 and gray SKU. The old B07XDDJ77N page was not available to confirm the listing relationship. This profile does not claim that every USB-C device can use its display output just because it has a USB-C connector.
Plan for a 4K signal at 30Hz
The indexed ADAM manual specifies HDMI up to 3840 × 2160 at 30Hz. That is a useful resolution, but it is not the same as 4K at 60Hz; a buyer sensitive to desktop motion, gaming or smoother screen movement should match the refresh rate to the intended use. The documentation also requires a host whose USB-C connection can carry display output. A standard USB-C charging or data port does not automatically satisfy that requirement. The manual's compatibility list names several operating systems, but buyers should check the exact host device and mode before relying on video. No claim about picture quality or observed monitor behavior is made here.
Separate the data port and charging port roles
The manual distinguishes the USB-A Gen 1 port, rated up to 5Gbps, from the USB-C connection that combines USB 2.0 data and a PD charging input. It lists the latter's data speed at up to 480Mbps. This matters if a buyer expects every visible USB-C socket to support high-speed file transfer: that assumption would not match the documented port roles. The manual also lists USB-A output at 5V and 0.9A maximum. It does not say that the adapter is a general-purpose powered hub for multiple high-draw accessories. Check which socket is intended for charger input and which for peripherals in the selected listing's diagram.
Reconcile the conflicting charging figure
The historic title advertises 60W Power Delivery, and reseller copy for the model also gives a maximum 60W pass-through figure. ADAM's indexed manual instead specifies a 20V/5A, 100W maximum PD input. Those values may describe a revision difference or input versus pass-through capability, but the sources do not explain the discrepancy or establish how much power reaches a laptop. This review therefore does not choose one value as the guaranteed output. A buyer whose computer requires a specific charging rate should ask ADAM or the seller for the current SKU's input and delivered-output ratings, and should check the charger and cable as well.
Confirm the selected product before ordering
The retailer records verify a gray CASA Hub i4 under AAPADHUBI4GY, while the indexed manual establishes the product family and port functions. They do not map B07XDDJ77N to that exact SKU, and the original manual file now leads to a 404 page. Use the tagged model search, inspect the product label and diagram, and confirm the USB-A, HDMI, PD and audio functions together. The record does not provide evidence for Ethernet, SD/microSD readers, multiple downstream data ports or a second display output, so none is represented as part of this model. No current price or stock claim is made.
