ATEN USB-C Multiport Dock
100% human

The ATEN USB-C Multiport Dock with 60W power pass-through is a great dock for those with USB-C devices (MacBook, iPad, Windows, Android and Chrome) that want something semi-permanent that sits under your laptop on the desk.

It won’t break the bank either. The ATEN USB-C Multiport Dock is $199 – about half the cost of a Thunderbolt dock, so if your needs are a little less demanding then this is what you want.

Le’ts put the ATEN USB-C Multiport Dock through its paces.

Power supply – Pass, but it is really only 45W passthrough

It draws 5V/3A (15W) from your passthrough power source – if any less it may affect functionality. It appears not to work with Qualcomm QC chargers unless they also support PD 2.0.

But while it will passthrough 60W, in reality, it only provides a maximum of 45W to the computer so you may need to power the laptop independently if it needs more.

Sorry – we were not game to test with an 80W USB-C charger in case it or the charger blew up!

Build – Exceed

Aluminium – it is solid. 280 x 750 x 145mm x 320g. It sits under the back of a laptop and has non-slip feet to keep it in place. And the 5° angle is just perfect.

Dual monitors – Pass at 30Hz

First Mac does not support Dual Monitor MST (Multi-Stream Transport), so dual monitors are for Windows only – a shame as it’s a perfect Mac companion.

It supports 2 x 1080p@60Hz via DisplayPort, HDMI or VGA. It is plug and go as Windows supports this.

Single monitors – Pass

We tested 1 x 4K@30Hz or less. It supports 1920×1080@60Hz. You can push it to 2560 x 1080 at 60Hz, but it depends on the monitor and cable quality.

iPad – Failable

It supports one external monitor and one keyboard. Caveat – the typical 12W charger USB-A to Lightning charger must be at least 30W to work correctly. It appears to support USB-A devices like flash drives. Support is dependent on iPadOS.

Chromebook – Pass

It is fully functional for Intel-based Chromebooks but again test before you commit.

Android – Failable

Depending on your smartphone or tablet, this may accept one external HDMI monitor, keyboard and USB devices supported by Android. Test first.

We tested with late-model Samsung Galaxy S10, Note10 and Tab S6 but these are optimised for DeX and did not work.

Port speeds – Pass

Given that port, one is a USB-C 3.1 Gen 1 is 5Gbps full-duplex we did not notice any speed reduction in using external USB-A SATA 6 (6Gbps half-duplex) or USB-C devices.

We also gained a full gigabit Ethernet connection.

GadgetGuy’s take – ATEN USB-C Multiport Dock does what is says

It is perfect for most 13” Windows laptops (dual screen support) or 13” MacBooks (single screen support) as a relatively lower-cost way to add lots of ports. And you can use it with Thunderbolt 3 devices as well.

It is more reliable than a cheap dongle – better quality build for starters, but the fact that it is a desktop device means less pulling cables in and out.

Remember this is not a Thunderbolt 3 device like ATEN’s UH7230 Multiport 85W dock but that costs $359 and needs Thunderbolt 3 to function.

We are rating it as a USB-C dock for single/dual screen operation in a desktop format it does everything it promises.
