Frequently Asked Questions

Q1: Will this dock work with any laptop? How do I make sure my laptop works with this dock? What kind of cable should I use to connect the dock to my laptop?

A1: This dock works with Windows 10 laptops equipped with Thunderbolt 4, and MacBooks running macOS 11 (Big Sur) or later. It doesn’t work with Linux or Chrome OS laptops, Thunderbolt 3 Windows laptops, or M1 MacBooks. It’s recommended that you use the included Thunderbolt 4 cable. If you need to use a different cable (due to loss etc.), then another Thunderbolt 4 cable would also be compatible.

Q2: I have a Windows 10 laptop with Thunderbolt 3 ports, will it work with this dock?

A2: For Windows 10 laptops with Thunderbolt 3 ports, we’d recommend a Thunderbolt 3 dock.

Q3: I have a laptop with two Thunderbolt 4 ports, but I have 2 external displays that only have HDMI inputs. How do I use them with this dock?

A3: You can use either a USB-C to HDMI cable or a USB-C to HDMI adapter to connect the dock to your external displays.

Q4: How many external displays can this dock support and what are the maximum resolutions?

A4: This dock supports connection to two external monitors via the USB-C Thunderbolt 4 downstream ports.

Below are the maximum resolutions:

1) Single monitor: Windows - 8K (7680 x 4320 @ 30Hz); macOS - 5K (5120 x 2880 @ 60Hz)

2) Dual monitor: 4K (3840 x 2160 @ 60Hz)

Q5: Why does the dock feel warm?

A5: When charging or transferring data at high speed, the dock’s temperature may increase. This heat is dissipated through the aluminum exterior, so it may feel warm to the touch. Don't worry, this is within the normal limits of the dock’s operation.

Q6: The charging output of the dock is listed as 85W, which is lower than my MacBook charger’s output. Will the dock still be able to power my MacBook?

A6: This dock supports up to 85W of charging via the Thunderbolt 4 upstream port (indicated by a computer icon). Power is dynamically distributed between this port and other power ports depending on the power requirements of connected devices. Therefore, sometimes the charging speed will be slower than the original laptop charger.

5 Stars
Finally a totally USB-C solution!
I have managed to use an USB-C to laptop charger converter to enable USB-C power input (a serious design misstep to not include it instead of a barrel jack) and with that I finally have USB-C power, USB-C video and USB-C hosting all simultaneously.Are you listening Anker? Delete the barrel jack and make it USB-C. If I can do it with a hack, you can certainly do it with superior design!
