Anker 575 (PowerExpand 13-in-1) Review 2026

Name: Anker PowerExpand 13-in-1 USB-C Docking Station
Brand: Anker
SKU: A8392

The Anker PowerExpand 13-in-1 USB-C Docking Station, also known as the Anker 575, is a full-size desktop dock that connects to your laptop via a single USB-C cable. It packs 13 ports into a compact vertical enclosure: two HDMI outputs, one DisplayPort, four USB-A ports, a 10 Gbps USB-C data port, an 18W USB-C PD port for phone charging, Gigabit Ethernet, SD and microSD card readers, and a 3.5mm combo audio jack. The standout feature is triple display support on Windows through Multi-Stream Transport (MST). You can run three external monitors at 1080p@60Hz, two at 2K@60Hz, or one at 4K@60Hz, depending on your laptop's DisplayPort Alt Mode version. An included 135W power adapter delivers 85W of passthrough charging to your laptop, enough for most 13 to 15-inch machines. Anker originally sold this as the "PowerExpand 13-in-1 USB-C Dock" before rebranding it under the 575 product number. At around $250, it sits below the Thunderbolt-based Anker 577 in price and bandwidth. The trade-off is clear: you lose the 40 Gbps Thunderbolt bandwidth and UHS-II card reader speeds, but you gain an extra video output port and compatibility with any USB-C laptop that supports DP Alt Mode and Power Delivery. For Windows users who need triple monitors from a USB-C dock without Thunderbolt, the Anker 575 is a practical choice. Mac users should note that macOS only supports Single-Stream Transport (SST), which means all connected monitors will mirror the same content.

Pros & Cons

What We Like

Triple display support on Windows via MST with 2x HDMI + 1x DisplayPort
85W USB-C Power Delivery charges most 13 to 15-inch laptops at full speed
13 ports cover nearly every connectivity need from a single USB-C cable
10 Gbps USB-C data port handles fast external drives and peripherals
Works with any USB-C laptop that supports DP Alt Mode, no Thunderbolt required
18W USB-C PD port dedicated to phone charging

What Could Be Better

macOS only mirrors displays, no extended desktop across multiple monitors
Workaround: Mac users who need multiple independent displays should consider a Thunderbolt dock like the Anker 577 or CalDigit TS4 paired with an Apple Silicon chip that natively supports multiple displays.
SD and microSD card readers limited to UHS-I speeds
Workaround: For faster card transfers, use a dedicated UHS-II card reader connected to one of the USB-A or USB-C ports.
18-month warranty is shorter than competitors like CalDigit (24 months)
Dock gets noticeably warm under full load with all ports in use
Workaround: Ensure adequate ventilation around the dock. The warmth is normal for a USB-C dock pushing 85W passthrough charging.
Linux not officially supported
Workaround: Linux users may find partial compatibility depending on kernel version and distribution, but Anker provides no guarantees or support.

Our Verdict

Very Good

The Anker 575 fills a specific niche well: it is a USB-C dock with three video outputs, 85W charging, and a generous port count, all without requiring Thunderbolt. If you have a Windows laptop with USB-C DP Alt Mode and want to run two or three monitors from a single cable, this dock delivers. The triple display capability through MST is genuinely useful for productivity setups where screen real estate matters. Build quality follows the Anker standard. The aluminum housing looks clean on a desk and keeps the weight manageable. The included 135W adapter is large but provides stable power for both the dock and laptop charging simultaneously. Port selection covers most bases. The 10 Gbps USB-C data port handles fast external drives, the four USB-A ports connect keyboards, mice, and other peripherals, and the Gigabit Ethernet provides a reliable wired connection. SD and microSD card readers support SD 3.0 / UHS-I, which is adequate but noticeably slower than the UHS-II readers on the Thunderbolt 577 model. The biggest limitation is macOS compatibility. Because Apple's macOS does not support MST, you cannot use multiple independent displays through this dock on a Mac. All connected monitors will show identical content. This makes the Anker 575 a poor fit for Mac users who need extended desktop across multiple screens. The 85W charging handles most ultrabooks but falls short for high-performance 16-inch laptops that draw 100W or more. Resolution maxes out at 4K@60Hz on a single monitor, which is fine for office work but limits users wanting dual 4K. The dock gets noticeably warm under full load with all ports populated, which is expected but worth knowing. At this price point, the Anker 575 competes well against the Dell D6000 and Plugable UD-6950Z. It offers a cleaner design and reliable Anker warranty support, though 18 months is shorter than what some competitors provide.

Frequently Asked Questions

Does the Anker 575 support triple monitors?

Yes, but only on Windows. The dock uses Multi-Stream Transport (MST) to drive up to three displays at 1080p@60Hz through its 2x HDMI and 1x DisplayPort outputs. On macOS, all monitors will mirror the same content because macOS does not support MST.

Can the Anker 575 charge my laptop?

Yes, the Anker 575 delivers up to 85W of passthrough charging via the USB-C host connection. The included 135W power adapter powers both the dock and your laptop simultaneously. 85W is sufficient for most ultrabooks and 13 to 15-inch laptops.

What is the difference between the Anker 575 and Anker 577?

The Anker 575 connects via USB-C (10 Gbps) and supports triple display on Windows via MST. The Anker 577 connects via Thunderbolt 3 (40 Gbps) and supports dual 4K or single 5K displays. The 577 has faster UHS-II card readers and higher bandwidth but requires a Thunderbolt port. The 575 works with any USB-C laptop that has DP Alt Mode support.

Does this dock work with MacBooks?

Partially. The dock provides charging, USB peripherals, Ethernet, audio, and card reader access on macOS. However, it does not support extended desktop across multiple monitors on macOS. All connected displays will show mirrored content only.

Do I need to install drivers?

No. The Anker 575 is plug and play. It uses native USB-C DisplayPort Alt Mode, which is handled by the operating system. No additional software or drivers are needed on Windows, macOS, or ChromeOS.
