The Anker Prime Docking Station (DL7400, model A83B3) turns one USB-C cable into a full desk setup. Connect a laptop to the upstream port and it can charge, link up to three monitors and reach wired network, storage cards, headphones and USB devices. It is designed for people who move a laptop between a desk and everywhere else.
The 14 connections
Anker lists the following ports:
- A 140W 10Gbps USB-C upstream port to the laptop
- Two 100W 10Gbps USB-C ports and one 100W 5Gbps USB-C port
- Two HDMI ports and one DisplayPort
- Two 5Gbps USB-A ports and one 480Mbps USB-A port
- A 2.5Gbps Ethernet port
- A headphone and mic combo jack
- SD and TF (microSD) card slots
The brand suggests plugging a mouse or keyboard receiver into the 480Mbps USB-A port, which is plenty for those devices and leaves faster ports free.
What DisplayLink means
This dock uses DisplayLink technology. Instead of relying only on the laptop's built-in video outputs, DisplayLink compresses the picture and sends it over USB, which is how a dock can drive more screens than the laptop could alone. It needs the latest DisplayLink driver installed, and Anker notes this is required. Anker lists compatibility with macOS 13.5 or later and Windows 10 and 11.
Three displays, one of them 8K
The dock can run three external monitors at once, and Anker says one of them can be 8K. In general, the resolution and refresh rate you actually get depends on the monitor, the cable and the laptop, so check the manual's display tables for your exact combination. One limitation is listed: the front USB-C ports do not support video output.
Charging
The upstream port delivers up to 140W to the laptop, enough for many larger laptops that use the USB-C Power Delivery standard. Each front USB-C port supports up to 100W charging as well as data. The total power is shared across the dock, so charging several devices at once may lower what each receives.
Smart display and cooling
A small smart display shows real-time information on charging power, display performance, the fan's cooling mode and settings. A built-in fan and what Anker calls ActiveShield 3.0 are intended to keep the unit cool and stable under load.
Size and contents
The dock measures about 7.7 x 3.6 x 1.9 inches (19.6 x 9.1 x 4.8 cm) and weighs 1.8 lb (about 0.8 kg). The box includes the dock, a 3.3 ft (1 m) USB-C to USB-C 3.2 Gen 2 cable, a 6 ft AC power cord, a safety sheet with a manual QR code and a 24-month warranty.
Who it suits
It suits remote workers, students and anyone with a laptop at a desk who wants multi-monitor output, wired networking and fast charging on one cable.
What to check before you buy
- Operating system: confirm your macOS or Windows version, and that you can install the DisplayLink driver (some managed work laptops restrict this).
- Laptop port: the laptop needs a USB-C port that supports the dock's connection.
- Charging needs: check your laptop's required wattage against the 140W upstream limit.
- Monitors: check the inputs on your displays and which cables you will need.
- Desk space: it needs ventilation, and has a fan.
