Our take
A8373 fits a USB-C setup that needs its four-port mix, one HDMI display, wired Ethernet, card reading, and a separate PD input, provided 4K/30Hz and up to 85W host output are sufficient.
A USB-C laptop user who needs the documented mix of USB data, one 4K/30Hz HDMI display, Gigabit Ethernet, card access, and up to 85W host charging..
Skip it when you need 4K/60Hz, macOS extended multi-monitor output, 100W delivered to the laptop, or a verified B0BMXQXXMW offer.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Anker specifies USB-C, USB-A, HDMI, Ethernet, and both SD and microSD.
- The power details distinguish 100W input from up to 85W host output.
- One USB-A and one USB-C data port are each rated up to 5Gbps.
What to weigh up
- HDMI is limited to 4K/30Hz and macOS MST expansion is unsupported.
- A separate 100W charger and cable are required for maximum pass-through.
- The historical Amazon ASIN is not mapped to A8373.

Full review: how the features affect your choice
What the features mean for you
Arrange the nine connections by their actual jobs
Anker's A8373 page presents a desk or travel dock with a mix of data, network, card, and display sockets. It lists one USB-C and one USB-A 3.2 Gen 1 data port, each up to 5Gbps, plus two USB-A 2.0 ports up to 480Mbps. It also includes Gigabit Ethernet, HDMI, and SD and microSD card slots. This mix helps someone connect both faster data devices and lower-bandwidth peripherals such as a keyboard or mouse. The four data ports are not four equal USB 3.0 ports, so plan which device goes where. The dedicated PD input is a separate role and does not count as a data socket.
Budget for the difference between 100W input and 85W to the laptop
The hub's power input accepts up to 100W from a compatible charger, but Anker specifies a maximum of 85W pass-through to the laptop because the hub itself uses power. A 100W charger and cable are required for that maximum, and Anker says they are sold separately. This distinction matters if a laptop normally needs close to 100W; the hub cannot provide the full input number to the computer. Check the laptop's charging requirement, the charger rating, and the cable before depending on a one-cable desk setup. The 100W figure is an input ceiling, not the delivered wattage at the host.
Match HDMI expectations to the one-screen limit
Anker lists one HDMI output with a maximum of 4K at 30Hz. That can be suitable for a single monitor where 30Hz fits the work, but it does not establish 4K/60Hz or multiple external display output. Anker also warns that macOS does not support MST display expansion through this hub. Confirm the computer's own USB-C video support and the required resolution before buying. If your setup depends on extended screens on a Mac, do not assume a multiport adapter with several sockets will create multiple desktops. The official A8373 page is the source for this exact limitation; details from another Anker dock should not be substituted.
Use the two card slots and Ethernet only where their specifications fit
The official product page lists SD and microSD reader slots with a published rate up to 104MB/s, plus an Ethernet port up to 1Gbps. Those functions can reduce the need for separate camera-card and wired-network adapters. The source does not specify which memory-card capacities or standards apply, whether both card slots can work at once, or how the reader rate changes with the card. Verify those details if your work depends on a particular SD standard. For wired networking, confirm that the computer's network setup and cable support the speed you need. Do not apply a card speed to USB ports or assume that Ethernet is faster than the surrounding network.
Search by A8373 and verify the port face before ordering
The Anker product page identifies model A8373, with A8373H11 for the black variant. The Amazon row's ASIN B0BMXQXXMW returned an internal error, and no source directly maps it to that model. The frozen title's count of four USB-A/C data ports aligns broadly with Anker's four data ports, but its A8373 identity remains unproven. Search the model code and compare the exact port layout. Anker sells several USB-C hubs with 100W PD and card slots, but their data and display arrangements vary. The link above is a tagged model search rather than an unverified direct detail page.
