Our take
Alxum's described USB/Ethernet combination is useful for a narrow connectivity job. Confirm which host plug ships and keep high-power devices on their own supply.
Buyers who need a compact USB/Ethernet adapter and can verify the selected host-plug package and power limits before connecting demanding devices..
Buyers who require a confirmed USB-C host variant, a display/card-reader dock, a powered charging hub, or an exact Amazon offer mapping.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Manufacturer and retailer sources describe three USB 3.0 ports and Gigabit Ethernet.
- USB-A and USB-C male host-plug options are described for the product family.
- The saved sources present interface ceilings rather than measured throughput.
What to weigh up
- The exact host-plug package and historical ASIN mapping are unresolved.
- The retailer cautions against high-power devices such as external hard drives.
- No HDMI, card-reader, or laptop charging function is documented.

Full review: how the features affect your choice
What the features mean for you
Use it to add wired networking and three USB connections
The manufacturer product page describes a combined USB hub and RJ45 Ethernet adapter: three USB 3.0 downstream ports plus a Gigabit network connection. That pairing suits a laptop or tablet that needs a wired network link while still attaching a keyboard, mouse, or other ordinary peripheral. It is a compact connectivity adapter rather than a full docking station; no HDMI, display output, card reader, or laptop power-delivery function appears in the inspected description. The source does not give a table for all traffic under simultaneous load. Confirm that this function mix matches your desk or field setup before comparing it with display-capable hubs.
Check which host connector is included
Alxum's indexed page describes USB 3.0 male and USB 3.1 Type-C male plug options, while the independent X2 Robotics page calls it a hub with USB-C adapter. The evidence does not establish whether a package includes both attached plugs, an adapter piece, or separate variants. This matters if the computer offers only USB-C or only USB-A. Inspect the selected package image and specification for its actual host end; do not infer universal compatibility from USB-C wording in the title. The manufacturer also lists Windows, Mac OS, Chrome OS, and Linux support, with a note about a driver patch for some older Mac versions. Check the host operating system and connector arrangement before ordering.
Interpret the speed figures as interface ceilings
The product description lists USB data up to 5Gbps and Gigabit Ethernet up to 1000Mbps. Those are interface ceilings, not promises of sustained file-copy or internet throughput. Actual USB transfers depend on the host, connected peripheral, cable, and workload; wired network speed depends on the router or switch, cable, service, and remote endpoint. The hub does not provide a simultaneous bandwidth breakdown for its USB ports and Ethernet adapter. A user who needs a consistent high-throughput storage pipeline should account for the shared host connection and choose a device with a verified manual for the exact variant. For web access or routine peripherals, the advertised combination may matter more than peak transfer numbers.
Respect the power limits around external drives
The retailer says this is not a standalone charger and cautions against high-power devices, including external hard drives. Adding sockets does not mean the unit can supply the current every device needs. The source does not list a port-level current rating, bundled adapter, or powered-hub mode. Avoid planning to charge a phone, power several bus-powered drives, or treat the RJ45/USB adapter as a general charging dock from the available evidence. If an external storage device draws substantial power, use its own supply or confirm that the selected Alxum version has a documented power input. Keep the source warning in the buying decision.
Search the product description and verify its identifier
The Alxum and X2 Robotics pages support a three-port USB 3.0/Gigabit Ethernet product family, but neither connects that product to historical ASIN B01IDETFA0. Feed code LYSB01IDETFA0-ELECTRNCS is based on the ASIN string and is not treated as a maker model. An old forum post includes a B01IDETFA0 Amazon link but gives no product title or model, so it cannot resolve the mapping. The affiliate destination searches Alxum and the distinctive three-port/Gigabit description. Compare the selected result's host connector, three USB-A data ports, and RJ45 jack, and do not assume a similar Ethernet adapter is the same item. This review makes no personal-testing, customer-review, current-price, stock, or sales claim.

Before you buy
Is B01IDETFA0 confirmed as this Alxum hub?
No. The saved sources do not map that historical ASIN to the Alxum product.
Can it power several external drives?
The retailer cautions against high-power devices, including external hard drives.
Does it provide HDMI?
No HDMI output is listed in the inspected product description.
Where can I check the current price?
