Everything you need for a laptop dock, but not as sleek or full featured as the cheaper competition.
Instead of getting to your desk and wasting time plugging your laptop in to five or more different devices, Aten’s UH7230 gives any Thunderbolt 3 enabled laptop a Gigabit Ethernet port, 2x USB3.1 Gen1 type-A ports, 1x USB3.1 Gen1 type-C port, separate 3.5mm audio input and output sockets, plus two graphics outputs - all via a single cable.
The DisplayPort output will pump out 4096x2160 at 60Hz, but if you have a 5K monitor with Thunderbolt 3 (i.e the LG UltraFine 5K Display), you can hook it up to the USB-C port and get the full 5120x2880 at 60Hz. You can use two 4K monitors at once if your computer’s graphics card can handle it.
The UH7230’s most useful feature is being able to supply 85W of power over the USB-C port. This means laptops like the 15in MacBook Pro don’t need a separate power adaptor to charge. The UH7230 can supply all its power needs and you can leave the power brick in your bag.
Setup is easy, with no drivers required. Just plug it in to your Thunderbolt 3 enabled computer and off you go. All the ports are available with built-in drivers on Windows and Mac. Aten are nice enough to include a Thunderbolt 3 USB-C cable in the UH7230’s box too, so you can get started right away.
With a street price of $559, the Aten UH7230 is $100 more than CalDigit’s TS3 Plus that does everything the Aten does, but $100 cheaper and with an extra USB port plus an SD card reader. The Elgato Thunderbolt 3 dock is also cheaper than the Aten, looks nicer and has identical ports. However, the CalDigit and the Elgato units do not include a Thunderbolt 3 cable, which on its own is a $50 purchase for a 1-meter length.
Despite the free cable, it’s difficult to recommend the UH7230. It costs more, isn’t as pretty and lacks the ports of its competitors.
