Anker 577 Docking Station review

Looking for a Thunderbolt 3 docking station that can charge our laptop, power our phone, drive two high-resolution monitors, and tidy up our desk at the same time?

Product Overview

We think the Anker 577 Docking Station (13-in-1, Thunderbolt 3) 85W Charging for Laptop, 18W for Phones, 4K Dual Display, 10 Gbps USB-C Data, Ethernet, Audio, SD 4.0 is designed to be a single-cable hub for users who need a lot of ports and reputable charging performance. It packs a broad selection of connectors, strong charging capability through Thunderbolt 3, and support for high-resolution external displays, which makes it appealing for office and home setups where flexibility matters.

What’s Included

We appreciate that the package is straightforward and ready to use out of the box. The dock ships with a 180W power adapter, a Thunderbolt 3 cable (2.3 ft), a welcome guide, and an 18-month warranty backed by Anker’s customer service. That means we’re usually able to plug in and configure without needing extra parts.

Design and Build

Physically, the Anker 577 has a compact, understated design that fits nicely on a desk without drawing attention. The housing is solid enough for daily transport between rooms or brief travel, yet not so heavy that it becomes cumbersome.

Size, Weight, and Materials

We find the docking station to be compact and reasonably rugged. The casing combines matte plastic with a subtle finish that resists fingerprints better than glossy alternatives. While it’s not military-grade, it looks like it will hold up under normal usage and the footprint is small enough to sit beside a laptop or monitor stand.

Port Layout and Accessibility

We like that ports are split between front and back faces to prioritize convenience. Front-facing USB ports and SD card slots let us access flash drives and memory cards without reaching behind a cluttered desktop, while back-facing connectors keep cables out of the way for a cleaner look.

Ports and Technical Specifications

This dock is promoted as a 13-in-1 solution, and it delivers a broad mix of connectors that cover most typical needs. Below we break the ports down clearly so we can see what’s available at a glance.

Below the table we’ll expand on each type and what they mean in practice.

Thunderbolt 3 Ports

One Thunderbolt 3 port is the host port used to connect to our computer and provide up to 85W of power delivery to compatible laptops. The second TB3 port can be used for a downstream device such as an external GPU, a daisy-chained drive, or a high-resolution monitor (supports 5K@60).

USB-C and USB-A Ports

The dock includes two USB-C ports and four USB-A ports. One USB-C port provides 18W Power Delivery that’s useful for fast-charging phones or powering smaller peripherals. The remaining USB ports are useful for external storage, keyboards, mice, and other accessories. When fast data transfers are required, the 10 Gbps USB-C data capability is where we plug in high-speed SSDs.

Video Outputs (HDMI and TB3)

For displays, the HDMI output supports 4K@60Hz, and a Thunderbolt 3 downstream port can support 5K@60Hz. When we connect both the HDMI and TB3 display outputs simultaneously, the dock can drive two displays at 4K@60Hz each, which is ideal for multitasking or visual workflows that demand high pixel density.

Card Readers, Ethernet, and Audio

We find the SD and microSD slots particularly handy for photographers and content creators who want a quick card dump, and these are SD 4.0-compliant for higher transfer speeds. The Gigabit Ethernet port is reliable for stable networking where Wi-Fi is weak, and the 3.5mm jack keeps legacy audio devices connected without an adapter.

Charging and Power Delivery

Power delivery is one of the dock’s strongest selling points. The dock is bundled with a powerful 180W power adapter that feeds the dock’s internal PD circuitry and powers attached devices.

Laptop Charging: 85W and 15W TB3 Ports

We note that one Thunderbolt 3 port negotiates up to 85W of Power Delivery, which is enough for many mainstream Windows laptops and non-M1 MacBooks. The other Thunderbolt 3 port provides 15W, which is better suited for smaller devices or when chaining TB3 peripherals. The 85W output will generally keep a typical 15–65W laptop charged during normal usage, but very power-hungry gaming or workstation laptops may still draw more than the delivered power during peak CPU/GPU loads.

Phone and Small Device Charging: 18W USB-C

An 18W USB-C PD port is included for phone charging, and we find it useful for a fast charge on most phones that accept PD. Because the power adapter supplies up to 180W in total, the dock can simultaneously provide the 85W laptop PD and the 18W phone PD without compromising basic needs for other devices in most real-world setups.

Power Sharing and Real-World Behavior

When we connect many high-power devices simultaneously, the dock dynamically allocates power. In practice, this means that if we connect a laptop requiring full 85W, multiple external drives, and a phone, the total available power is shared intelligently by the dock. We recommend checking the power demands of very high-wattage laptops or multiple fast-charging phones if planning to push the dock to its limits.

Display Support and Multi-Monitor Performance

If multi-monitor support is a key requirement for our setup, this dock offers strong capabilities and flexibility.

Native Resolutions and Refresh Rates

The Thunderbolt 3 downstream port can support 5K@60Hz for a single high-resolution display, while the HDMI port supports 4K@60Hz. If we connect both simultaneously, the dock supports two displays at 4K@60Hz each. This makes it well-suited for productivity setups where we want crisp text and ample screen real estate.

Compatibility Notes for Different Hosts

We should be careful about host limitations. Some laptops, especially certain MacBook models with M1 silicon, have restrictions on multiple external displays — and the product specification states explicitly that the dock is not compatible with M1 MacBooks. On Windows laptops and non-M1 MacBooks with Thunderbolt 3 or 4 ports, we can expect the advertised functionality. It’s also important to have Thunderbolt drivers and firmware up-to-date on Windows systems to get the best experience.

Setting Up Dual Displays

To use two 4K monitors at 60Hz, we connect one display to the dock’s HDMI port and another to the Thunderbolt 3 downstream port using a compatible Thunderbolt 3 to DisplayPort or USB-C to DisplayPort/HDMI cable depending on the monitor. We often need to configure display settings in the OS to arrange monitors and set scaling, but performance for video playback and office work remains smooth.

Data Transfer and Storage Performance

This dock is positioned for high-bandwidth data movement, thanks to a 10 Gbps USB-C data lane and SD 4.0 support.

USB-C 10 Gbps Throughput

When we plugged in a USB-C NVMe enclosure (capable of 10 Gbps), we observed sustained transfer speeds that approach the expected limit for a 10 Gbps link. In real-world testing with large files, we measured sustained transfers in the high hundreds of MB/s. This means the dock is genuinely capable of supporting fast external drives for video editing, backups, and other data-heavy work.

SD and microSD Card Performance

The SD 4.0 slot supports modern high-speed SD cards used by DSLRs and mirrorless cameras. During our card-to-laptop transfers, the card reader provided notably faster results than older, USB 2.0-based readers. This is a practical improvement for photographers and videographers who move large RAW and video files.

Practical Notes About Bandwidth Sharing

We should remember that the dock’s internal bandwidth is shared across many ports, particularly when using Thunderbolt 3 video streams and multiple high-speed peripherals simultaneously. If we run a 5K display and transfer large files at the same time, latency or slower transfer rates may appear compared to a single-task scenario. For most productivity tasks this isn’t noticeable, but for heavy concurrent workflows (high-res video playback plus simultaneous large file transfers) it can matter.

Network and Audio

The dock’s network and audio features are straightforward but important for many deskside setups.

Ethernet (Gigabit)

The RJ45 Gigabit Ethernet is reliable and delivers near-full gigabit speeds in our testing, which is useful when we need low-latency, stable connections for video conferencing, gaming, or large uploads and downloads. We observed throughput near the expected gigabit limit under typical conditions.

3.5mm Audio Jack

The 3.5mm AUX port supports headsets and speakers, and it’s handy for quick audio switching without adjusting separate USB headsets or Bluetooth. We tested both headphone output and line-level speaker output and found the jack to behave like a standard PC audio output.

Compatibility and Limitations

Understanding compatibility constraints is crucial before purchasing.

Supported Systems

We recommend this dock primarily for Windows laptops and non-M1 MacBooks that have Thunderbolt 3 or 4 ports. The Thunderbolt connection is necessary for the full feature set, including power delivery and multi-monitor video.

Unsupported Systems

The dock is not compatible with M1 MacBooks, Linux, or Chrome OS laptops according to the product information. This is a key limitation for anyone who uses these systems; trying to use the dock with unsupported hosts may produce limited functionality or no operation.

Driver and Firmware Considerations

On Windows machines we advise ensuring that the Thunderbolt and USB drivers are updated, and that any vendor-specific Thunderbolt control software or security settings permit the dock. Occasionally, Windows will require user authorization to enable Thunderbolt accessories. On Macs without M1 chips, the macOS should support the features when connected to Thunderbolt 3 ports.

Real-World Testing and Benchmarks

We put the Anker 577 through a series of practical tests to see how it performs in everyday multitasking setups.

Charging Under Load

In charging tests with a midrange Windows laptop (that supports 85W PD), the laptop maintained battery charge during typical office work like web browsing, document editing, and video calls. Under heavier CPU/GPU loads like video rendering or gaming, the laptop battery occasionally trended downward because actual device consumption exceeded 85W. That is expected behavior and is not a fault of the dock — it’s a result of power limits relative to the laptop’s peak draw.

File Transfer Tests

Using a high-speed NVMe enclosure connected to the 10 Gbps-capable USB-C port, we transferred large video files and observed sustained transfer speeds in the upper hundreds of MB/s. This is acceptable for editing and backups without noticeable bottlenecks compared to other 10 Gbps docks.

Dual 4K Displays

Running two 4K@60Hz displays (one via HDMI, one via TB3) produced crisp visuals and smooth desktop animations. Video playback at 4K was smooth on both displays simultaneously for typical streaming and local media playback. Demanding GPU tasks were limited by the laptop’s GPU capability rather than the dock.

Ethernet Throughput

Over a wired gigabit connection, we observed near-gigabit throughput consistent with our ISP and local network tests, enabling fast transfers and low-latency calls.

Setup and Troubleshooting Tips

We find a few practical pointers helpful when setting up and using the dock.

Initial Setup Steps

• Plug the included 180W power adapter into the dock and a power outlet.
• Connect the dock to our laptop’s Thunderbolt 3 port using the included 2.3 ft Thunderbolt 3 cable.
• Connect displays, storage devices, and network cable after the host recognizes the dock.
• Check system settings to authorize Thunderbolt devices if prompted (Windows Thunderbolt software or macOS security settings).

Common Issues and Fixes

• If displays don’t appear, ensure the host supports external displays over Thunderbolt and that cables/adapters are rated for the targeted resolution and refresh rate.
• If charging negotiates at a lower wattage, confirm that the host accepts the provided power profile and that the dock’s TB3 host port is used for laptop charging (not a downstream port).
• For driver-related Ethernet or Thunderbolt issues on Windows, update chipset, Thunderbolt, and network drivers from the laptop manufacturer.

Pros and Cons

We think it’s important to be balanced, so here are the key advantages and drawbacks we encountered.
