Your needs, this model
Does it fit your priorities?
Can four USB-A devices use the documented 5Gbps data route in a surface installation?
Yes. Exact I/O and original manual identify four downstream Type-A ports; current kit includes the matching computer and hub-power arrangement.
Explore this need in the finder →Can it operate in the documented USB 2 fallback?
Yes. The explicit fallback supports the four outputs at USB 2 capability rather than 5Gbps.
Explore this need in the finder →Does it provide four Type-C data outputs?
No. Its actual downstream map is four Type-A ports, despite a conflicting generic table row.

The Coolgear USBG-3X4M is a four-Type-A data hub with a separate Type-B computer input. Its metal body, mounting flanges and screw-lock-compatible connections are the important differences from a small travel splitter. Consider it when the hub will stay in place and an accidentally disturbed cable would create an avoidable interruption.
Those mechanical features solve a particular problem. They do not add native monitors, networking or laptop charging. Start with the four peripheral connections you need, then decide whether mounting and cable retention justify this style of hub.
The computer path remains one shared 5Gbps connection
The documented data capability is USB 3.2Gen1 at up to 5Gbps, with USB 2 compatibility. All four outputs share the connection to the host. Four sockets can keep several devices connected, but cannot give each device a separate full-bandwidth upstream link.
That distinction matters with storage. Several simultaneously busy drives create a different workload from one drive beside low-bandwidth controls. Compare the intended combined use rather than treating the number of sockets as a transfer-speed multiplier. This is a specification assessment, not our own throughput test.
Use the Type-B input and matching cable
The exact port description and original manual identify one Type-B upstream socket and four Type-A peripheral outputs. The current package lists a USB 3 Type-A-to-B host cable. Check the host computer's connection before treating that supplied arrangement as a match for a Type-C-only machine.
Compatible screw-lock leads and ordinary USB cables have different retention hardware. A normal cable can connect where the guide allows it, but does not become locked merely because the hub has screw positions. Check which connections need retention and which matching cables the chosen package actually supplies.
The adapter powers the hub, not the laptop
The current manufacturer package lists a 12V/3A output adapter, power cord and two-pin Phoenix connector. The power table gives 100–240V AC input. The 36W adapter rating describes the supply; it is not 36W available independently at each peripheral or power delivered to the computer.
This review uses the specified externally powered arrangement. Match the unit's actual connector and instructions before installing a replacement supply. The published documents contain differing power-connection details, so an older diagram is not a reason to improvise wiring on a different physical unit.
Leave room for mounting and cable bends
The case supports wall or surface mounting, while the current package excludes the surface fasteners. Measure the actual flange positions and allow room for the plugs, locks and cable bends. A body that fits the available shelf space can still be awkward if its connected leads are forced against a wall.
Port-status LEDs can help identify active connections, but they do not replace checking the attached device and host. The industrial enclosure and retention features also should not be read as proof of a particular environmental certification or measured reliability result beyond the maker's actual specification.
When the USBG-3X4M makes sense
The current software table lists Windows, MacOS and Linux and says extra hub software is unnecessary. A connected peripheral may still need its own driver or application. Confirm that separate requirement before deciding the complete installation is ready.
Shortlist this model for four Type-A USB 3 data devices, a fixed mounting position and a matching powered setup. Compare another hub for Type-C data outputs or a different connection count. Choose a dock with separately documented capabilities for displays, wired networking or laptop Power Delivery; this hub's power adapter is not a substitute for those functions.
