Anker 556 vs Anker 554 - USB4 Hub vs KVM Dock 2026

Anker 556 vs Anker 554: Similar Ports, Completely Different Jobs

The Anker 556 USB-C Hub and Anker 554 USB-C Docking Station look like they belong in the same shopping cart because both are Anker, both use USB-C on the host side, both are driverless, and both have HDMI plus DisplayPort. The buying decision is not really a normal port-count race, though. These products solve different desk problems.

The Anker 556 is a compact USB4 hub. Its YAML lists a 40Gbps upstream connection, one HDMI 2.0 output, one DisplayPort 1.4 output, Gigabit Ethernet, one USB-C data port, two USB-A data ports, and passthrough charging from a separate USB-C charger. It is best understood as a small Windows-first USB4 desk hub for one laptop, Surface, HP EliteBook, Lenovo, or handheld PC setup.

The Anker 554 is a larger USB-C KVM docking station. Its YAML lists two USB-C host ports, one HDMI 2.0 output, one DisplayPort 1.4 output, USB-A, USB-C, audio, a magnetic remote, two included 1 m USB-C host cables, and an included 180W power adapter. The point is not maximum bandwidth. The point is switching one shared keyboard, mouse, monitor pair, USB accessories, audio setup, and charging between two laptops.

The short verdict: The Anker 554 wins overall because it has the higher product score, the stronger charging setup, and the more distinctive use case. Buy it if you want one desk for two USB-C laptops. Buy the Anker 556 instead if you have one Windows USB4 laptop and care more about 40Gbps bandwidth, Ethernet, and a smaller hub than KVM switching.

If you are still deciding whether a hub, USB-C dock, DisplayLink dock, or Thunderbolt dock fits your laptop, start with our USB-C vs Thunderbolt docking station guide. It explains the host-port limits that matter for both of these Anker products.

Quick specs comparison

What they have in common

Both products avoid DisplayLink. That means there is no display driver to install, but it also means the laptop must provide the video signal natively. The Anker 556 needs a USB4, Thunderbolt, or full-function USB-C port that can support its display modes. The Anker 554 needs USB-C ports with Power Delivery, DisplayPort Alt Mode, and USB 3.2 support from each host for the full KVM setup.

That shared driverless design is a good thing for simple Windows desks. You avoid software updates, login-screen display surprises, and the protected-video limitations that come with some DisplayLink workflows. It also means neither product is a magic fix for a laptop with the wrong USB-C port. If the host has charge-only USB-C, data-only USB-C, or a limited display path, these docks cannot create video support out of nothing.

They also share the same basic video connector mix: HDMI plus DisplayPort. That is useful because many desks still mix one HDMI monitor with one DisplayPort monitor. You do not have to rely on two identical outputs or special adapters for the common dual-monitor setup.

The big difference is what happens upstream. The 556 puts its energy into one high-bandwidth USB4 connection. The 554 splits the desk between two USB-C host inputs and adds a switch. If you choose the wrong one, the spec sheet may still look good, but the product will feel awkward in daily use.

Bandwidth and host connection

The Anker 556 wins the pure bandwidth category. Its YAML lists a 40Gbps upstream connection and an included 1.6 ft USB4 cable. That is the main reason to buy it. A 40Gbps link gives more room for high-resolution display output and fast peripherals than normal 5Gbps or 10Gbps USB-C hubs, assuming the laptop actually supports the required USB4 or display mode.

The Anker 554 is much more limited on paper. Its YAML lists USB-C host connectivity at 5Gbps. For fast external SSD workflows, capture devices, or heavy USB data use, that is not competitive with the 556. The 554 is not trying to be a high-bandwidth workstation dock. It is trying to be the single control point for two computers.

That distinction matters more than the numbers. If you use one laptop and want Ethernet, fast USB, dual displays, and a compact cable setup, the 556’s faster upstream link is valuable. If you use a work laptop during the day and a personal laptop at night, the 554’s second host port is more valuable than USB4 bandwidth because it reduces the number of cables and peripherals you touch every time you switch machines.

Bandwidth winner: Anker 556. Its 40Gbps USB4 host link is far stronger than the Anker 554’s 5Gbps USB-C host link.

KVM switching and desk workflow

This is the category that decides the comparison for many buyers. The Anker 554 is a KVM dock. Its YAML says it lets two USB-C laptops share monitors, keyboard, mouse, USB accessories, and audio, with switching from a button or magnetic remote. That is a specific workflow. It is not just another port.

A two-laptop desk can become messy fast. A work computer may need the webcam, keyboard, mouse, monitor pair, and headset from 9 to 5. A personal MacBook or Windows laptop may need the same gear after work. Without a KVM dock, you either move cables manually, buy separate peripherals, or rely on a monitor’s limited built-in USB switch. The 554 exists for that exact friction point.

The Anker 556 does not compete there. It has one upstream host connection. It can be a nice small dock for a single laptop, but it does not switch a shared desk between two computers. If you want to move it between laptops, you unplug and replug the host cable. That is fine for travel or occasional use. It is not the same as a dedicated two-host KVM setup.

The 554 also includes two 1 m USB-C host cables. That matters because both host cables need to carry power, data, and video. The 556 includes one USB4 cable, which is right for its one-host job, but it does not solve the second-laptop problem.

KVM winner: Anker 554, by default. It is the only one of these two products built for two host laptops.

Display support and Mac caveats

Display support is close only if you look at the maximum number of monitors. Both list up to two external displays, but the details differ.

The Anker 556 has the higher display ceiling. Its YAML lists a single-display mode up to 7680x4320 at 30Hz through HDMI or DisplayPort, plus dual 3840x2160 at 60Hz through HDMI plus DisplayPort. If you have a Windows USB4 laptop and want dual 4K from a compact hub, the 556 has the cleaner spec.

The Anker 554 lists one HDMI 2.0 port and one DisplayPort 1.4 port, each rated up to 3840x2160 at 60Hz. Anker advertises dual 4K@60Hz on compatible hosts. That is enough for many office desks, but it does not have the single 8K mode or 40Gbps upstream link that makes the 556 stand out.

macOS is where neither product is perfect. The 556 YAML says Mac display support is mixed and not the main advertised use case. It explicitly warns against buying it for dependable dual extended Mac displays. The 554 YAML is more specific: Anker says macOS mirrors the displayed content and only supports dual 4K@30Hz through this dock. That makes the 554 useful for a MacBook only if mirrored displays are acceptable or if the real goal is switching peripherals between a Mac and another laptop.

For people who need reliable multi-monitor MacBook support, a native Thunderbolt dock or a DisplayLink dock may be a better fit. Our best docking stations for dual monitors guide covers broader options.

Display winner: Anker 556 for one Windows USB4 laptop. Anker 554 if the display setup is part of a two-laptop KVM desk.

Ports and everyday connectivity

The port mix tells you who each product is for. The Anker 556 includes one USB-C data port, two USB-A data ports, HDMI, DisplayPort, Gigabit Ethernet, USB-C PD input, and the USB4 upstream connection. That is a compact desk-hub layout. Ethernet is the practical advantage. If your laptop lacks RJ45 and you want a wired network connection without a separate dongle, the 556 has it built in.

The Anker 554 does not have Ethernet, which is its most obvious missing port. Its YAML lists one downstream USB-C 3.2 data port with 20W charging, two USB-A 3.2 ports, one USB-A 2.0 port, HDMI, DisplayPort, and a 3.5mm combo audio jack. It also has the two USB-C host ports that enable the KVM workflow. The USB-A 2.0 port is not exciting for data, but it is fine for a keyboard, mouse receiver, or other low-bandwidth accessory.

Neither product has SD or microSD card readers. If card slots are part of your normal workflow, Anker’s own 555 or 575 may be a better fit. The 556 also lacks audio, while the 554 includes a 3.5mm combo jack. That gives the 554 a small edge for shared headset or speaker setups at a KVM desk.

The 556 has the cleaner one-laptop utility mix because Ethernet and USB4 bandwidth are hard to ignore. The 554 has the better shared-desk mix because audio, more host cabling, and switching matter more when two laptops use the same peripherals.

Port winner: tie. The Anker 556 has Ethernet and USB4 bandwidth. The Anker 554 has KVM host ports, audio, and an extra USB-A port.

Charging and power

Charging is one of the strongest reasons the Anker 554 wins overall. Its YAML lists a DC-barrel power input, an included 180W power adapter, up to 100W host charging for one laptop, and up to 65W to each laptop when both USB-C host connections are active. That is exactly what a two-laptop KVM dock needs. It can keep two normal USB-C laptops topped up without forcing you to add another charger to the desk.

The Anker 556 uses USB-C passthrough charging. Its YAML lists up to 85W to the host laptop, but the wall charger is not included. The setup tips say to add a 100W USB-C PD charger to the PD-IN port, and the common issues mention charging problems or display instability when the charger is underpowered. That does not make the 556 bad. It just means the real desk setup depends on a charger you supply.

For a single ultrabook, 85W is often enough. For a busier desk, the 554 is easier. The power adapter comes in the box, the dock is built around a larger power budget, and the split-charging rule is clearly documented in the product YAML.

Power winner: Anker 554. It includes the power supply and offers stronger host-charging flexibility.

Windows, macOS, and ChromeOS fit

The Anker 556 is best for Windows USB4 systems. Its YAML calls out Windows 10 or later and frames dual-display use around USB4, Thunderbolt, or full-function USB-C hosts. The editorial copy also mentions Surface, HP EliteBook, Lenovo, and ROG Ally style setups. That is a narrow but real audience: one capable host, high display bandwidth, Ethernet, and compact size.

The 554 is broader in one way and narrower in another. It supports Windows, macOS, and ChromeOS for basic docking, but each host needs Power Delivery, DisplayPort Alt Mode, and USB 3.2 for the full feature set. Its Windows story is stronger for independent dual-monitor use. Its macOS story is more limited because the YAML says external displays mirror and dual 4K is capped at 30Hz.

The best way to think about it is this: choose the 556 around a host-port standard, and choose the 554 around a desk workflow. If the laptop has USB4 and the desk has one computer, the 556 is cleaner. If the desk has two laptops and the monitor behavior is acceptable, the 554 is the product with the more useful day-to-day design.

Value and score

The site scores are close, but the Anker 554 is ahead: 7.2 versus 7.1 for the Anker 556. That small gap fits the practical comparison. The 556 has stronger technology in the upstream link, but its value depends heavily on the right host, the right charger, and the right display expectations. The YAML also notes that it was unavailable on Amazon.com at the time of review.

The 554 has its own caveats. It lacks Ethernet and card readers, host bandwidth is only 5Gbps, and buyer feedback mentions display handoff and wake issues on some laptop combinations. It also is not the right answer for a Mac dual-extended-display setup. Even with those limitations, it solves a clearer problem. A two-laptop desk with shared peripherals is annoying, and the 554 directly reduces that annoyance.

For buyers comparing these two by price alone, the YAML gives an MSRP for the 556 but not for the 554, so this comparison should not pretend to know the street-price gap. The safer value claim is based on included hardware and use case. The 554 includes the 180W power adapter, two host cables, and magnetic remote. The 556 includes the USB4 cable but requires a separate charger for powered use.

Value winner: Anker 554 if you need KVM switching. Anker 556 if you already own a proper USB-C charger and only need a compact one-laptop USB4 hub.

Verdict: Anker 554 wins for two-laptop desks, Anker 556 wins for one Windows USB4 laptop

The Anker 554 wins this comparison overall because it has the higher score in our product data and a more distinctive reason to exist. It is not faster than the 556, and it does not have Ethernet, but it gives two USB-C laptops one shared desk. The included 180W power adapter, two host cables, magnetic remote, HDMI, DisplayPort, USB peripherals, audio jack, and split charging make sense together.

The Anker 556 is still the better technical hub for the right single-laptop setup. Its 40Gbps USB4 upstream link, Gigabit Ethernet, single 8K@30Hz mode, and dual 4K@60Hz mode are stronger than the 554’s raw connectivity specs. If your desk is built around one Windows USB4 laptop or handheld PC and you do not need KVM switching, the 556 is the more sensible product.

Choose the Anker 556 if:

• You use one Windows USB4, Thunderbolt, or full-function USB-C host
• You need a compact hub with Gigabit Ethernet
• You want HDMI plus DisplayPort from one small device
• You want up to dual 4K@60Hz or single 8K@30Hz on a capable host
• You already have a proper 100W-class USB-C charger for passthrough power
• You do not need KVM switching, audio, card readers, or an included power brick

Choose the Anker 554 if:

• You want two USB-C laptops to share one keyboard, mouse, monitor pair, USB setup, and audio connection
• You value KVM switching more than USB4 bandwidth
• You want the included 180W power adapter and two included 1 m host cables
• You need up to 100W charging for one host or up to 65W for each of two hosts
• You are comfortable with a driverless USB-C DisplayPort Alt Mode setup
• You do not need built-in Ethernet or card readers
