説明
A laptop with two ports is a laptop with a bottleneck. The Acasis 21-in-1 docking station restores the connectors a workstation needs: three Thunderbolt 4 ports, HDMI 2.0 driving 8K at 60 Hz, 2.5G Ethernet, SD and TF 4.0 card readers, three USB-C 3.1 and four USB-A 3.1 ports, two USB-A 2.0 ports and three 3.5 mm audio jacks. It feeds up to 90 W to the host and accepts 240 W input, so one cable carries data, video, audio and charge.
Underneath it is Intel JHL8440 silicon and an aluminium alloy body weighing 523 g, with a 100 cm Thunderbolt 4 cable and a 240 W adapter supplied. Total bandwidth runs to 40 Gbps, which is what makes an 8K display at 60 Hz, a 2.5G network link and an NVMe-class external drive plausible at the same time. Compatibility covers Windows, macOS and Linux, and the sealed aluminium chassis is sized at 120 mm wide to sit under a monitor riser rather than slide around a desk.
The honest reason to buy it is not the port count. It is the discipline of arriving at a desk, plugging in one cable and having monitors, network, storage, audio and power resolve in the time it takes to sit down. Video editors moving terabytes need the 40 Gbps lanes; everyone else needs the single cable.
A workstation is a set of connections. This is the set.

Application Scenarios
Video editors connect camera cards through the SD and TF 4.0 readers, keep a scratch drive on a Thunderbolt port and drive a reference monitor over HDMI while the laptop charges, all from one cable. Software developers run dual displays, wired 2.5G networking and external storage without a port expander stack. Photographers offload shoots at full card speed while backing up to a second drive. Studio and office deployments mount the hub once per desk, so hot-desking staff arrive with a single laptop connector and leave with the same desk configuration they had yesterday.
Frequently Asked Questions
Q: Will it charge my laptop while everything is connected?
Yes. The dock passes up to 90 W to the host laptop and accepts 240 W input through the supplied adapter, so charging and peripherals run simultaneously over one cable.
Q: What display resolution does it support?
The HDMI 2.0 output supports 8K at 60 Hz, and the three Thunderbolt 4 ports can drive additional displays depending on the host device's capabilities.
Q: Does it work with macOS and Linux as well as Windows?
Windows, macOS and Linux are all listed as compatible systems. Thunderbolt 4 hosts are required to reach the full 40 Gbps bandwidth.
Q: Is the network port fast enough for video work?
The 2.5G Ethernet port is included specifically for high-throughput work such as shared storage and media transfers over a wired network.
Q: What is included in the box?
A 100 cm Thunderbolt 4 cable and a 240 W adapter are supplied accessories, so the dock is usable as soon as it is unboxed.
Q: Does the dock need its own power supply?
Yes, and it is supplied. The 240 W adapter feeds the dock, which in turn passes up to 90 W to the laptop, so the host charges while every peripheral stays connected.
Q: Can it drive more than one external monitor?
The HDMI 2.0 port alone supports 8K at 60 Hz, and the three Thunderbolt 4 ports can carry additional displays, with the final count depending on the host device's display support.
