Inateck HBU3VL3-4: Three USB 3.0 Ports and a Gigabit Ethernet Jack on One Captive Cable
Condition
Unused new old stock, still inside the factory poly bag with its short captive USB 3.0 type A cable coiled alongside the body. The original kraft retail box is included and was opened for inspection and photos only; nothing was taken out of the bag. The housing itself is printed with the inateck wordmark beside the port panel, and the label on the box lid reads INATECK HBU3VL3-4, 3 Port USB3.0 HUB + Gigabit Ethernet Converter, carrying CE, FCC and RoHS marks along with a barcode sticker that reads X000M74DM3, Inateck HBU3VL3-4 US, New. Through the plastic the black housing looks clean and unscuffed, the three blue USB 3.0 receptacles are clear, and the close-up of the RJ45 jack shows bright contacts with no visible insertion wear.

Product Overview
The HBU3VL3-4 is a one-piece laptop adapter: a short captive USB 3.0 type A plug on the host end, and at the other end a slim black bar carrying three downstream USB 3.0 receptacles in a brushed panel plus an RJ45 Gigabit Ethernet jack on the tail. The inateck wordmark is printed on the housing next to that port panel and repeated on the box alongside the manufacturer's own web address, so the part and its packaging agree on who built it. The retail box label spells out the specification buyers usually have to hunt for, listing Super Speed 5 Gbps, an interface of USB3.0x3 and RJ45, dimensions of 100 x 30 x 20 mm, a weight of 50 g, and operating system support for Windows XP, Vista, 7, 8 and 8.1 plus Mac OS. It is the answer to a thin laptop or tablet that dropped its network port, and it brings back three usable ports at the same time instead of consuming one.

Frequently Asked Questions
Which operating systems does the packaging actually list?
The box label lists Windows XP, Vista, 7, 8 and 8.1, and Mac OS. Linux is not printed on this packaging, so we are not claiming it. If you need a specific modern OS or a driver-free experience on it, check the chipset requirements against your machine before you buy.
Will all three USB ports and the Ethernet jack run at full speed at once?
Everything on this adapter shares the single USB 3.0 uplink rated at 5 Gbps on the label, so heavy simultaneous traffic on a drive and the network divides that budget the way any bus-shared hub does. We have not measured throughput here, so treat the 5 Gbps and Gigabit figures as the manufacturer's printed ratings and verify against your own workload.
Does it need a power supply, and how big is it?
No power adapter is included, none is shown on the packaging, and no separate power input is visible on the unit in the photos; the captive USB cable is the only connection in the bag. The label gives the size as 100 x 30 x 20 mm and the weight as 50 g, so it stows flat in a laptop sleeve.
There is only one of these, so why buy this single bagged adapter instead of chasing a surplus lot or an auction pallet?
Because this one is already a known quantity. You are buying the exact adapter in these photos: the original kraft box, the inateck-marked housing still inside its factory poly bag with the captive cable, and nothing else. It has never come out of that bag, so we have not powered the unit up and there is no bench result to quote; the printed box label and these four photographs are the spec, and the housing, the three ports and the RJ45 contacts show no handling in any of them. A mixed lot or a pallet gets you unknown units at unknown grades plus a pile of pieces you did not want. This is one piece, photographed from four angles, with our no-hassle satisfaction guarantee behind it, and there is no second unit to substitute if it sells. Shipping is $8 flat rate and free once your order passes $28, and it leaves the Idaho warehouse the same or next business day.
A leftover from the ultrabook years, when laptops shed their Ethernet jacks faster than the buildings around them shed cable, and this little black bar quietly put the port back. Slide it out of the bag, plug it into whichever thin machine is annoying you this week, and give it a network to hold onto.
