Our take
A conventional four-port USB-A desktop hub with an included adapter in TRENDnet's current V3 documentation, while the old ASIN's revision remains open.
A desk that needs four USB-A data ports, external power, and a separate hub cable, after confirming the current unit's revision and connector ends..
Buyers who need verified current ASIN continuity, a USB-C host connection, video or Ethernet, or a guaranteed per-port charging rate.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The current TU3-H4 V3 page specifies four USB-A 3.0 downstream ports.
- A 1m cable and 20W adapter are listed for V3.
- USB 2.0/1.1 backward compatibility and broad OS families are documented.
What to weigh up
- B0046TML4E is not tied to the current V3 revision.
- The 5Gbps rate is a maximum interface claim, not a measured result.
- Adapter wattage does not promise a fixed output at every port.
Specifications and exact model details
The key details
| Model covered | TU3-H4 (V3 specifications; historical revision unverified) |
|---|---|
| Host connector | Micro-USB Type-B upstream connector on the hub; the computer-side cable plug is not confirmed in the saved passage. |
| USB 3.x data ports | Four USB-A 3.0 data ports, advertised up to 5Gbps in the current V3 specification. |
| Installation | Desktop hub with a 1m included cable in the V3 package. |
| Hub power | A 20W adapter is listed; TRENDnet also describes bus-powered limits and powered charging modes. |
| Host charging | No laptop USB-C PD charging function is documented; external-power modes concern attached devices. |

Full review: how the features affect your choice
What the features mean for you
Add four USB-A data connections to a powered desk
The TU3-H4 is a conventional desktop USB hub: one host connection leads to four USB-A 3.0 outlets. That layout suits keyboards, mice, printers, flash drives and other peripherals that use USB-A. TRENDnet's current V3 page includes a 1m cable and a separate power adapter, so the product can sit away from the host instead of hanging directly from its port. The historic row names TU3-H4, but the exact V3 revision is not proved for B0046TML4E. Check the model label and connector panel on a current offer rather than assuming the old ASIN identifies today's revision.
Plan around the four-port count and 5Gbps ceiling
TRENDnet lists four Type-A USB 3.0 ports and a maximum data rate up to 5Gbps. That specification provides a useful ceiling for the hub's interface, not an independent transfer measurement or a promise that four drives will each sustain that rate simultaneously. The host, cable, connected drives and simultaneous transfers affect real results. If your primary use is high-speed storage, verify the current V3 manual and consider how many devices will operate at once. For lower-bandwidth peripherals, having four accessible ports may matter more than the highest advertised figure.
Use external power when the connected devices need it
The current manufacturer page specifies a 20W adapter and describes a lower bus-powered mode as well as charging modes when externally powered. That distinction matters because the hub's power source can affect how peripherals behave. The 20W label is the adapter's total rating, not a guarantee that every port can deliver a fixed maximum to every type of device. TRENDnet lists up to 0.9A total in bus-powered mode and different limits for supported charging modes with the adapter. Match those details to the attached equipment, and verify that the chosen offer includes the correct supply.
Check the upstream connector and cable reach
TU3-H4 V3 uses a Micro-USB Type-B upstream connection and comes with a 1m USB cable. That is different from a hub with an integrated USB-A or USB-C host lead. Check that the computer, cable and hub end match the exact unit, especially if the hub will sit below a monitor or inside a workstation shelf. The cable length provides some placement flexibility, but may still be short for a larger desk. Confirm the current product revision before ordering a replacement cable or installing the hub permanently.
Use the operating-system list as a starting point
TRENDnet lists Windows, Mac and Linux support and backward compatibility with USB 2.0 and 1.1 devices. Those statements identify broad platform families but do not provide a version-by-version feature matrix for every historic or current release. Basic USB devices may work across a broad set of hosts, while power behavior and device-specific drivers can still vary. If the hub is for a managed office computer, specialized Linux environment or older workstation, verify your OS and peripherals against current manufacturer support. Do not infer video, Ethernet or laptop-charging features; this is a USB data hub.
Keep TU3-H4 separate from TU3-H4E and verify the revision
The nearby TRENDnet model TU3-H4E has its own saved profile and different cabling and power details. The model suffix is meaningful, so those specifications are not transferred to TU3-H4. TRENDnet's official page documents TU3-H4 V3; the Amazon B0046TML4E page was not readable and does not reveal its revision. Search by TU3-H4 and compare the four-port panel, Micro-USB Type-B upstream connection, cable length and included adapter. This review uses official manufacturer specifications and does not claim personal testing, buyer consensus, price, stock or sales.
