The short answer
The Anker 555 is the simpler pick if one HDMI display and faster USB data ports cover your needs. The 553 may suit a setup that needs two HDMI outputs, but dual-display behavior depends on your computer and operating system. Check the exact model and laptop before choosing: the products share an eight-in-one label, but their ports differ.
This comparison uses published specifications, not hands-on testing. Anker product documentation is the source; regional product listings and revisions can vary.

Anker lists for the 555 two USB-A and one USB-C data port at 10 Gbps, one USB-C PD-in port, HDMI, Ethernet, SD, and microSD. Its HDMI supports up to 4K/60 with compatible source hardware. The power rating is not consistent across Anker’s own pages: the 555 product page labels PD-IN as 85 W max, while its comparison page lists up to 100 W input and 85 W to the laptop. Check the documentation for the exact regional A8383 unit before relying on either input figure. Official 555 specifications, Anker’s 553 and 555 comparison.
For the 553, Anker documents two HDMI ports, two USB 3.0 ports at 5 Gbps, gigabit Ethernet, UHS-I SD and microSD, and 100 W PD input with up to 85 W to a laptop. Anker gives different dual-display results for Windows and Mac, depending on DisplayPort version. Official 553 and 555 comparison.
Where the trade-offs show up
Anker 555: faster data and a single display
Pros: Anker specifies 10 Gbps data ports, one HDMI output rated up to 4K at 60 Hz, both card formats, and gigabit Ethernet. This suits a one-monitor setup with several peripherals.
Cons: It has one HDMI output, so it cannot meet a requirement for two HDMI-connected monitors. Video depends on DisplayPort support from the host. Confirm the PD input and bundled equipment for your region.
Anker 553: two HDMI connectors
Pros: Two HDMI ports offer more connection options for a multi-display desk. It also includes Ethernet and both card readers.
Cons: Its documented USB data ports are 5 Gbps, below the 555’s stated 10 Gbps. Dual display is not universal: Anker lists different modes by operating system and DisplayPort version. Verify your specific computer and whether it can extend to multiple screens.
Which one fits your setup?
Choose the 555 if one display and higher stated data-port speed matter most. Consider the 553 if two HDMI connections are useful and its documented display mode matches your laptop. If you have a Mac or a high-refresh monitor, verify the exact host limitation and target mode first. Our USB-C hub buying guide explains what to check.
