ELECOM will release the U3HC-T040PBK, a USB Type-C hub that attaches to the side of a desk or a steel shelf using a magnet on its underside, in late August. It carries 3 USB-A ports and 1 USB Type-C port, so a single unit handles both charging the host PC and expanding port count. The cable is permanently attached, measuring roughly 0.3m, so there is nothing to misplace[1].
Built Around the Idea That the Hub Should Not Move
Anyone who keeps a USB hub loose on a desk knows the problem: every time a plug goes in or out, the hub slides across the surface or flips over. The U3HC-T040PBK solves that in hardware. A magnet on the bottom lets it stick to the side of a steel desk or to a shelf board[1].
Once fixed in place, plugs can be inserted and removed with one hand. There is no need to hold the hub down with the other. Moving it to the side of a desk or onto a shelf also frees up surface space. ELECOM notes that you should confirm in advance that the mounting surface actually accepts a magnet[2].
3 USB-A Ports, 1 Type-C Port, and Dual Self and Bus Power
The port layout is 3 USB-A and 1 USB Type-C, for 4 ports total. The USB-A ports are data-only and are meant for everyday peripherals such as a mouse, a keyboard, or a flash drive. ELECOM does not recommend charging smartphones or tablets from the data-only ports[1].
The physical arrangement is deliberate. USB-A ports sit together on the top face, while the USB Type-C port is placed on the side. Separating frequently swapped devices from a permanently connected power source keeps cables from crossing each other[1].
Power handling covers both self-powered and bus-powered operation. Available current is up to 3.5A total across 4 ports in bus-powered mode and up to 3.5A total across 3 ports in self-powered mode, with a 1.5A ceiling on each individual port[2].
100W In, 95W Out to the Host PC
The USB Type-C port on the side supports USB Power Delivery (USB PD) and accepts up to 100W of input. Connect an AC charger there and the hub will charge a laptop or tablet through the same connection. Because the hub itself consumes 5W, the maximum available to the host is 95W. Reaching that figure requires a 100W AC charger[1].
That charging port also carries data. It does not support video output, however, so an external display is outside its intended use[2].
USB 5Gbps Transfer, with macOS Tahoe 26 Support
The hub runs at USB 5Gbps (USB 3.2 Gen1), which ELECOM describes as roughly 10 times the theoretical speed of Hi-Speed USB (USB 2.0). Whether that speed materializes depends on whether the connected device also supports USB 5Gbps[1].
ELECOM states that the design stabilizes data quality between the PC and the hub, based on measurements taken from certification testing of transmitted and received signals, in order to minimize the compatibility problems that tend to appear between connected devices[1].
Supported operating systems are Windows 11 and 10, macOS Tahoe 26, and iPadOS 26. The body measures approximately 87mm wide by 27mm deep by 24mm tall excluding the cable, weighs about 51g, and comes in black only. It meets VCCI Class B and carries a 1-year warranty[2].
On the environmental side, the product qualifies for ELECOM's THINK ECOLOGY mark, awarded to products meeting the company's own criteria. The cited items include an outer box designed for shipping efficiency, packaging built only from paper, cardboard, and poly bags, and a reduction of plastic weight in the packaging by at least 20 percent compared with the company's internal baseline products[1].

Price: 4,180 Yen at Street Level
The release is set for late August at a street price of 4,180 yen, or 3,800 yen before tax[1]. ELECOM's own product page lists a standard price of 6,435 yen (5,850 yen before tax) and marks the item as coming soon[2]. The street price is likely the more useful reference when the product actually reaches shelves.
Summary
ELECOM's U3HC-T040PBK is a 4-port USB hub that mounts magnetically to the side of a desk or a steel shelf. It combines 3 USB-A ports with 1 USB PD capable USB Type-C port, delivering 95W of a 100W input to the host PC. Transfer runs at USB 5Gbps, and the attached cable measures roughly 0.3m. It arrives in late August at a street price of 4,180 yen. For anyone tired of a hub that shifts every time a plug moves, it addresses the problem directly.
