Overview

Modern ultra-thin laptops like the Apple MacBook Air, Dell XPS 13, and Lenovo ThinkPad X1 Carbon offer sleek portability, but they frequently cut back on essential physical connectivity. The Anker 555 USB-C Hub—also identified in technical listings as the Anker PowerExpand 8-in-1 USB-C PD Media Hub—is engineered to solve this deficit. It expands a single USB-C port into eight distinct connections, combining high-speed data transfer, video output, wired network connectivity, card readers, and power pass-through.

Synthesizing published tech analyses and aggregated buyer feedback reveals that the Anker 555 stands out in a crowded category dominated by generic adapters. By upgrading standard 5Gbps USB ports to 10Gbps USB 3.2 Gen 2 and providing 4K video output at 60Hz, it targets demanding remote workers, student researchers, and digital media editors who need reliable peripheral performance without carrying a bulky desktop dock.

Design and Build

The Anker 555 features a minimalist rectangular chassis wrapped in matte gray anodized aluminum. This metal casing serves a dual purpose: it matches the aesthetic of modern premium laptops and acts as a passive heatsink to dissipate thermal energy generated during high-wattage power transfer. Measuring roughly 4.76 by 2.17 inches and weighing 4.1 ounces, the hub slides easily into a laptop sleeve or tech pouch.

Port layout is clean and logical. Along one side, you will find two USB-A 10Gbps ports alongside a matching USB-C 10Gbps data port. The adjacent side houses full-size SD and microSD card slots, while the end cap contains an RJ45 Gigabit Ethernet port. The HDMI port and dedicated 100W Power Delivery input sit opposite the data ports. A short, built-in USB-C cable (around 7 inches) connects directly to your computer. Verified user feedback notes that while this attached cable is durable, its limited length can leave the hub hanging awkwardly if your laptop sits high on a vertical desktop stand.

Key Features and Performance

Performance testing across hardware teardowns and user reviews highlights several standout capabilities, alongside a few operational constraints worth understanding before purchase:

  • 4K 60Hz HDMI Output: Unlike budget dongles capped at a choppy 30Hz refresh rate, the Anker 555 supports crisp 4K output at 60Hz over HDMI 2.0. However, achieving 60Hz requires your host laptop to support DisplayPort 1.4. Older laptops limited to DisplayPort 1.2 will automatically drop down to 4K at 30Hz.
  • High-Speed 10Gbps Data Transfer: The included USB-A and USB-C data ports leverage USB 3.2 Gen 2 protocols, delivering theoretical transfer speeds up to 10 Gigabits per second. In real-world media transfers with external NVMe drives, buyers report consistent throughput hovering between 850 MB/s and 950 MB/s, vastly outperforming legacy 5Gbps hubs.
  • 100W Power Delivery Pass-Through: The dedicated USB-C power input accepts chargers up to 100W. The hub reserves up to 15W for its own operational overhead and connected accessories, passing up to 85W straight to your laptop. Note that a wall adapter is not included in the box; you must use your laptop's stock charger or a secondary high-wattage USB-C block.
  • Dual Card Readers: The SD and microSD card slots operate at UHS-I speed standards (up to 104 MB/s). They can read and write simultaneously, which simplifies workflows for photographers transferring media across separate storage cards.
  • Gigabit Ethernet: The RJ45 port delivers stable gigabit wired networking, eliminating wireless dropouts during large file transfers or video conferences.

Under heavy simultaneous usage—such as delivering 85W of pass-through power while driving a 4K display and copying large media folders—the aluminum shell gets noticeably warm to the touch. Operational telemetry confirms temperatures remain within safety parameters, but users should maintain proper ventilation around the unit.

Who It Is For (and Who Should Skip It)

Recommended for: Remote professionals, travelers, and creative workers who require a compact multi-port solution. It is especially suited for MacBook Air and PC ultrabook owners who need to connect external monitors, flash drives, memory cards, and wired internet through a single cable drop.

Who should skip it: Power users who require dual external extended displays should look elsewhere, as the Anker 555 only supports a single external monitor mirror or extension stream. Photographers who demand ultra-high-speed UHS-II card transfers will also find the UHS-I slot speeds restrictive. Additionally, desktop users needing multi-gigabit networking or downstream Thunderbolt daisy-chaining should consider dedicated AC-powered Thunderbolt docks.

Alternatives Worth Considering

When evaluating the market, a few close competitors warrant attention:

  • UGREEN Revodok Pro 8-in-1 USB-C Hub: Offers an almost identical port selection at a competitive price point, though users should check specific model revisions to ensure 10Gbps bandwidth rather than standard 5Gbps specs.
  • Satechi USB-C Multi-Port Adapter V2: Features a slick aesthetic designed to match Apple hardware, but often retails at a higher price while offering lower power delivery pass-through headroom.
  • CalDigit TS4 Thunderbolt 4 Dock: For stationary desk setups, this fully powered dock offers immense expansion, multi-monitor support, and 98W charging, albeit at a significantly higher cost and larger physical footprint.

Final Verdict

The Anker 555 USB-C Hub strikes an excellent middle ground between lightweight travel dongles and heavy desktop docking stations. By pairing 10Gbps data transfer speeds with 4K 60Hz display support and 85W pass-through charging, it addresses the most common pain points of modern laptop connectivity. Minor quibbles like a short tethered cable and UHS-I card slot limits do little to diminish its standing as a versatile, dependable workstation tool.
