Our take
Anker 556/A83A8 combines USB4, three 10Gbps data ports, HDMI and DisplayPort, Gigabit Ethernet, and PD input with a maker-listed 85W host-output ceiling. B0BM46RVL8 is mapped to A83A8 by a separate saved source row; B0BR93RXJM and its bundle remain unresolved.
A USB4-capable laptop user who wants fast data ports, wired networking, display output, and documented host charging, and can use the verified A83A8 offer..
A buyer who needs confirmed simultaneous maximum modes on two displays, a card reader, a verified B0BR93RXJM bundle, or a host charging rate above the maker's 85W ceiling.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Anker's official page and manual identify A83A8 and its detailed port roles.
- Three data ports are listed up to 10Gbps, alongside HDMI, DisplayPort, and Gigabit Ethernet.
- The maker distinguishes 100W PD input from up to 85W host output, and a separate Amazon row maps B0BM46RVL8 to A83A8.
What to weigh up
- The published display limit is up to 8K/30Hz; combined dual-display behavior depends on the exact host.
- The USB-C data port does not charge or carry video, and no card readers are listed.
- The earlier B0BR93RXJM mapping and its extra 3.3-foot cable bundle remain unverified.
Specifications and exact model details
The key details
| Model covered | A83A8 |
|---|---|
| Host connector | USB4/USB-C host connection; confirm video and power support on the exact computer. |
| USB 3.x data ports | One USB-C and two USB-A data ports are listed up to 10Gbps; these ports do not charge or carry video. |
| Installation | The manufacturer package lists one 0.5m USB4 cable; the extra 3.3-foot cable in an old title is unverified. |
| Hub power | A separate USB-C PD input is listed up to 100W. |
| Host charging | Anker lists up to 85W delivered to a connected host; actual negotiation depends on the host, charger, and cable. |

Full review: how the features affect your choice
What the features mean for you
Choose A83A8 when a compact USB4 connection must cover several tasks
The Anker 556 combines a USB4 host connection with USB data, video, Ethernet and laptop power pass-through. Its specification is aimed at a user who wants to add conventional USB devices and wired networking while also connecting a monitor and charging the host through one accessory. The eight-in-one label counts a mix of inputs, data ports and functions; it does not mean eight USB-A sockets. The host port, display outputs, network connection and PD input each have different roles. Review the manufacturer's port diagram and count only the connections that match your setup. The current profile is for the A83A8 model family, not proof that historical ASIN B0BR93RXJM still points to that hub.
Set a display target using the published single-output modes
Anker lists HDMI and DisplayPort outputs up to 8K at 30Hz. The manual describes each output mode with a single connected display; it does not establish that both outputs can run simultaneously at their maximum modes on every host. A laptop's USB4 or USB-C port, graphics capability, operating system and monitor all matter. If your setup requires two external monitors, a particular refresh rate or a specific resolution combination, check Anker's current compatibility guidance for that exact computer before relying on both connectors. The page's high-resolution figure is a manufacturer specification, not a claim about tested results on every system.
Keep the fast data ports distinct from charging and video
The official port list includes one USB-C and two USB-A 3.2 Gen 2 data ports, each advertised up to 10Gbps. The product page explicitly marks these as data-only, with no charging or video output. This distinction can prevent a common port-role mismatch: the USB-C data connector is not the power input and should not be selected as a display connection. The ports provide a useful home for storage and ordinary USB peripherals, but the listed maximum is an interface ceiling. Three connected devices share the hub and host connection, so do not assume each can independently sustain 10Gbps at once.
Understand PD input and the separate host charging figure
Anker specifies up to 100W power input through the PD connection and up to 85W output to a connected host. Those figures describe different sides of the power path. The adapter and cable supplying the hub must meet the required USB Power Delivery level, while the host may negotiate a lower rate. The PD connector is not another downstream data port. Buyers should compare the 85W host figure with their laptop's charging requirement and verify that the charger and cable are suitable. The available manufacturer information is enough to distinguish input from host output, but it is not a measurement of charging time for any particular computer.
Add Ethernet when a wired network is part of the desk
The official page lists an Ethernet port at up to 1Gbps. That can be useful for a laptop user who wants a wired network connection alongside storage and display functions. It is a stated port capability, not a guarantee of internet speed; the router, cable, service plan and host system still determine the actual network result. The inspected specification does not call the Ethernet port faster than Gigabit, so a buyer needing multigigabit networking should look for a hub with that exact capability documented. This is a concise connectivity feature rather than evidence of any tested latency or throughput.
Verify the bundle and the current listing before purchase
The official Anker package description includes a 0.5m USB4 cable. The frozen title also claims an Anker 515 USB4 cable measuring 3.3 feet, but the inspected manufacturer package information does not confirm that extra item. It may be a separate bundle or a changed listing; the evidence does not settle which. A separate saved Amazon source row loaded B0BM46RVL8 and identifies A83A8, so that exact tagged destination is supported for that row only. The earlier B0BR93RXJM page returned a cache miss, so it remains unmapped. Confirm the model, included cables, ports and finish on the offer you choose. This review does not claim a current price, stock, user-review consensus or personal experience.
