Our take
CH-204U3-K is a candidate for a powered desktop that needs four switched USB 3.0 data ports. Confirm the upstream plug and treat the charge-port and cable figures as unresolved conflicts.
A desktop user who needs four switched USB 3.0 data connections and an included hub supply, and can verify the host plug and charging-port details before ordering..
Skip it when a verified host connector, a guaranteed charging current, a long lead, or known simultaneous-load performance is essential.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor

Full review: how the features affect your choice
What the features mean for you
A powered hub for four USB 3.0 data devices
The CH-204U3-K is aimed at a desktop arrangement with several USB peripherals and a separate power supply. Atolla says it adds four USB 3.0 data ports and includes a 5V/3A AC adapter. That makes the port map more concrete than an unspecified multiport claim: there are four identified data connections plus a distinct charging connector. The source does not establish whether the four data ports have separate upstream bandwidth or what happens when several high-draw drives operate together. Treat the advertised up-to-5Gbps transfer rate as a listed interface figure, not a measured simultaneous copy rate across all ports.
A dedicated charge port is useful, but its rating conflicts
Atolla labels one connector for smart charging, separate from the four data ports. The official page says up to 2.4A in its lead description and later detailed section, while another feature bullet says up to 2.1A. Because the maker page conflicts with itself, this review does not choose one number as definitive. Buyers who need a minimum charge rate for a particular phone or tablet should verify the exact unit documentation before counting on that output. The source also does not state charging behavior when multiple devices are connected, so a maximum for one port should not be treated as a guaranteed system-wide charging budget.
Switches provide port control
The product page describes four illuminated individual on/off switches for the USB ports. This is helpful when a user wants to disconnect or power down a peripheral without unplugging its cable. The maker’s wording associates the switches with each USB port, while the page also separates a charging port from the four data ports. It does not clearly explain whether the dedicated charging connector has its own switch. Buyers who need to control that port independently should check the physical unit or the full manual rather than extrapolating the switch count.
Cable and placement deserve a quick check
The official product page gives the lead as 65cm, then describes it elsewhere as 26 inches. Those measurements are close but not identical, and the product page itself does not reconcile them. Either description points to a short desktop reach rather than a long extension. Measure the distance from the intended host location to the spot where the hub will sit, especially if the computer is under a desk or behind a monitor. The page does not establish the upstream connector type in the text captured here, so verify it from the exact listing or product label before ordering for a particular computer.
A known model does not prove the old Amazon offer is current
The manufacturer identifies CH-204U3-K and the US-plug variant, and an indexed product-reference record associates the old B083XTKV8V clue with that model. That is useful identity evidence but does not establish that the historic Amazon page still presents the same variant. Search for the model code, then match the included adapter, four data ports, one charging port and switch arrangement. Do not assume every Atolla powered hub has the same layout; the manufacturer lists other products in the same family with different port counts and power supplies. This evaluation is based on the product specification, not a personal test or customer-review summary.
Separate data expansion from host and power requirements
The most concrete reason to choose this model is the four switched USB 3.0 data connections with a separate supplied power adapter. Before using it as the center of a setup, check how its upstream connector attaches to the host, because the text description inspected here does not identify that connector. Also decide whether one dedicated charging port is enough for the devices that need power. The manufacturer’s adapter rating tells the buyer what is listed in the box; it does not establish how much simultaneous current every downstream port can supply. These checks keep the known model layout separate from assumptions about a different powered-hub product.

Before you buy
How many USB data ports does the CH-204U3-K have?
Atolla lists four USB 3.0 data ports and a separate smart-charge port.
Is a power adapter listed in the box?
Yes. The maker lists a 5V/3A AC adapter.
How much current does the charge port provide?
The official page conflicts between up to 2.1A and up to 2.4A, so the exact figure is unresolved.
