Connect up to Two 4K Displays

ALOGIC’s Dual 4K Universal Compact Docking Station’s twin HDMI outputs enable you to connect two external displays at resolutions up to 4K.

The dock’s inbuilt DisplayLink technology ensures you experience the highest-possible screen resolutions for your computer monitor, regardless of your computer model, or whether you connect to USB-A or USB-C ports.

When you expand your screen real estate with the CH2, you have better oversight of your work. This oversight can improve your efficiency and productivity.

Comprehensive Connectivity for Your Desk

The CH2’s comprehensive suite of high-performing ports supports the versatile connectivity needs of homes, schools, and businesses. The dock’s USB-A [3.2 Gen 2, 10Gbps] and USB-C ports [3.2 Gen 2, 10Gbps] keep essential USB accessories such as external drives, scanners, keyboards, and mice humming.

Connect your laptop to the CH2 for up to 100W pass-through charging [when the CH2 is connected to an external power adapter], and connect to the Internet with Gigabit Ethernet when security and stability are paramount. The CH2 also features an SD 4.0/UHS-II Card Reader, so you can rapidly transfer your bulky multimedia libraries to and from the dock.

Passthrough Charging While You Work

The compact CH2 is built to fast-charge your laptop with up to 100W power delivery while you run multiple displays, USB accessories, and Ethernet, all over a single USB-C cable*. All you need to do is plug your laptop in when it’s time to get to work, and unplug when it’s time to take your laptop on the road.

*When connected to a host computer with USB-C ports that support USB Power Delivery, the CH2 will connect peripherals and charge the laptop over a single USB-C cable. USB-A enabled laptops can be charged from the dock using the ALOGIC DCAP-SPL USB-C Data + Power Splitter (available separately).

When you need your laptop for mobile work, the CH2 docks can also operate by connecting directly with your computer’s USB port [without an external power supply]. However, factor in that the docks’ USB-C ports are inactive in the absence of a power adapter connection, due to power constraints.
