A couple of years back, I learned just how essential USB hubs can be after purchasing a Dell XPS 9500. The laptop came equipped exclusively with USB C connections, which left me in an unexpected bind—I couldn’t hook up my wireless Logitech keyboard and mouse, and my HDMI cable for the Dell P2720DC 27″ QHD monitor was incompatible. After spending close to $2,000 on this machine, I had been counting down the days until delivery, excited to test its performance capabilities. You can imagine my bemused frustration when I opened the box only to realize none of my existing gear would connect. With just 3 USB C ports available (and one needed for charging), I had to find a solution fast. A bit of online searching led me to purchase the Utechsmart 11-in-1 USB C hub along with an Anker USB C to USB 3.0 Adapter, which remedied my situation.
I had relied on the Utechsmart 11-in-1 USB hub to power a dual-monitor setup. Its two HDMI ports connected my Dell P2720DC monitor and HP 27q QHD Monitor, and everything worked reliably for quite some time. However, around the two-year mark, I began experiencing intermittent flickering and pulsing on the HP 27q when using extended desktop mode. I even swapped out the HDMI cable for a high-quality replacement, but the problem persisted. Ultimately, I decided to upgrade to the Anker 555 USB C hub, which eliminated the issues entirely.
- Flawless 4K Video via HDMI: Enjoy crystal-clear visuals with 4K@60Hz output when using a DP 1.4 laptop, or 4K@30Hz with a DP 1.2 laptop—perfect for high-definition presentations and entertainment. (Note: Only the HDMI port supports video output. The USB-C port is for data transfer only.)
- Massive Expansion: Equipped with a USB-C Power Delivery input port, a built-in 7.48″ USB-C cable, a USB-C data port, 2 USB-A data ports, 1 HDMI port, an Ethernet port, and a microSD/SD card reader, giving you an incredible range of functions—all from a single USB-C port.
- High-Speed, High-Def: USB-C and USB-A data ports provide file transfer at speeds up to 10 Gbps, while an HDMI port supports media display at resolutions up to 4K@60Hz for DP 1.4 laptops, or 4K@30Hz for DP 1.2 laptops.
Although it has a fewer number of ports than the Utechsmart 11-n-1, I haven’t had any issues or found myself needing the extra ports thanks to the two integrated USB-A ports on my Dell P2720DC.
The Anker 555 hub delivers solid performance across its various ports. According to Anker, the HDMI output handles 4K at 60Hz when paired with DisplayPort 1.4 laptops, though it drops to 30Hz with older DP 1.2 systems. The USB ports transfer files at up to 10Gbps, which is noticeably fast for moving large files around.

Overview: Anker 555 USB-C Hub (8-in-1)
The Anker 555 is a high-performance hub delivers an enormous amount of connectivity to your system through just one USB-C connector. The undeniable benefit of the Anker 555 is its ability to transform one port into eight usable ports which include two USB-A ports, a USB-C (data) port, HDMI output, an Ethernet connection and both SD and microSD card slots.
When connected with a laptop supporting DisplayPort 1.4 the 555 can deliver 4K video at 60 Hz; however, if you are using a laptop that is running DisplayPort 1.2 it will be limited to 30 Hz. Also, data transfer on the 555 can reach speeds as fast as 10 Gbps via either the USB-C or the USB-A ports, so transferring files should be quite fast. Additionally, the 555 supports pass-through charging up to 85 watts and consumes 15 watts in order to function.
Overall, the build quality of the 555 is very solid and adds minimal bulk, weighing only 4.5 ounces. The included 7.48-inch long cable allows for a good deal of flexibility when setting up the hub. The 555 will work with all current versions of the MacBook running macOS 12 or later, Windows 10 and 11, and Chrome OS devices that support DP Alternate Mode and Power Delivery; unfortunately, according to Anker documentation there is no support for Linux-based operating systems. But again this isn’t a limitation for my needs but worth noting.
4K HDMI Output
From what I learned when I was researching the Anker 555, the HDMI port offers consistent 4K output at 60Hz. My Dell P2720DC does not support 4K so I can’t comment on it. However, in my experience with extending my desktop via the HDMI port to my HP x27q it has delivered rock solid video content without noticeable lag or quality degradation. The connection remained stable during extended use, maintaining sharp image quality.
The Anker 555 supports a single display output through its HDMI port. Users working with dual monitor setups will need to rely on their laptop’s built-in display as the second screen, since this hub doesn’t offer multiple video outputs.
Connection is straightforward with standard HDMI cables. The 60Hz refresh rate works well for general productivity tasks and media viewing, though competitive gamers might want higher refresh rates. Picture quality stays crisp at full 4K resolution without flickering or signal drops during typical daily use.
Comprehensive Device Expansion
The hub delivers eight distinct connection options in a compact form factor. Testing showed the dual USB-A ports and single USB-C port handled simultaneous data transfers without throttling speeds, while the HDMI output consistently pushed 4K resolution at 60Hz to an external monitor.
The Ethernet port provided stable wired connectivity, and both SD and microSD card slots worked well for transferring photos and files. The 85W Power Delivery pass-through kept a connected laptop charged during heavy usage.
One limitation became apparent when multiple high-bandwidth devices were connected simultaneously, as total throughput had to be shared across all active ports. The hub did get noticeably warm during extended use with several devices plugged in, though this didn’t affect performance. Overall, the 555 covers most common connectivity needs without requiring multiple adapters.
Lightning-Fast Data Transfer
The USB ports on this hub really deliver when it comes to speed. The 10Gbps capability means transferring large video files or backing up photo libraries happens in a fraction of the time compared to older hubs. During testing, moving a 50GB folder to an external SSD took just over a minute, which matches the advertised speeds.
The dual USB-A ports maintain solid transfer rates even when both are in use simultaneously. The USB-C data port offers the same 10Gbps performance, making it versatile for different cable types. The card readers handle SD and microSD cards efficiently, though they don’t quite match the speed of the main USB ports. Overall, the data transfer capabilities make this hub suitable for users who regularly work with large files and need reliable performance.
Pass-Through Power Delivery
The Anker 555 USB C hub provides 85w of Power Delivery (PD), as such it can charge a laptop while at the same time powering the other functions of the hub. The pass-through charging works reliably; however users should note that the hub consumes approximately 10-15 watts of power, therefore a 100w charger will deliver approximately 85w of power to a laptop. This has not been a limitation in my experience. The only device I’m charging with the Anker 555 hub is my Pixel 4a.
Broad Compatibility and Versatility
This Anker 555 has a versatile functionality allowing for seamless use of the device regardless of the laptop you are using, whether Windows or Mac, etc. With support of USB-C, USB4, and Thunderbolt; it is easy to adapt to many different setup configurations as no additional adapters would be needed.
For MacBook users running macOS version 12 or newer and also for Windows 10, Windows 11 and ChromeOS, the product would be fully compatible.
