So why invest in the SD5780T? Just one cause: Rather of a few downstream Thunderbolt four ports, it drops a person in favor of an HDMI 2.1 port. That is a apparent concession to the Personal computer marketplace, versus the Thunderbolt-dependent Mac marketplace, and it is a as well as in our reserve. Downstream power through the host Thunderbolt 4 port marginally boosts, from a rated 90W to 96W, much too.

Note: This evaluation is component of our ongoing roundup of the best Thunderbolt docks. Go there to understand about competing products, what to glance for in a Thunderbolt dock, and purchasing recommendations.

In overall, the SD5780T provides four USB-A ports (which include one optimized for smartphone charging, two USB-C/Thunderbolt 4 ports for downstream connectivity, additionally an HDMI two.one port, a 2.5Gb ethernet port, an SD4. UHS-II SD card slot (while not a microSD card slot), and a three.5mm jack for a mic and headphone. Like the SD5700T, the dock incorporates a compact electrical power button and LEDs that gentle when the dock is driven and related. The Thunderbolt four cord is about 38.five inches, wonderful and roomy.

In a natural way, Kensington also features a pair of Kensington lock slots as effectively, which are identified on the facet of the docking station.

Kensington provides no devoted USB-C ports on the SD5780T, but that is not automatically a damaging. For just one, the entrance-mounted USB-A port supplies 1.5A for charging (not speedy-charging) a smartphone. But the two other downstream Thunderbolt four ports deliver 3A of present, which can quick-cost a smartphone, if your cellphone charging cable takes advantage of USB-C.

The natural way, the one HDMI 2.1 port will electrical power an external 4K monitor at up to 120Hz if just a single display is utilized. Incorporating a next display screen possibly involves a specialized, extra buy, either a USB-C dongle or a specialized cable. I was only equipped to press 30Hz to an exterior display screen if linked to a person of various USB-C dongles on my desk. Employing a specialized Thunderbolt-to-HDMI cable ($18 on Amazon) my notebook was ready to thrust a 60Hz to the second exhibit, which will be much more cozy on your eyes. But if all that is much too a lot of a problem, you may well want to acquire a Thunderbolt dock with numerous display ports that you can just plug cables into, in its place.

Physically, the Kensington SD5780T sits flat on your desk, measuring seven.seven x two.ninety five x 1.2 inches and .95 lbs ., with no vertical stand. (It ships with a somewhat substantial 180W electric power supply that will maintain it tethered to your desk, nevertheless.) The chassis is designed of an beautiful brushed aluminum, which helps remove any warmth concerns.

Our tests showed that the SD5780T arrived shut to providing its rated power. Our assessments indicated that it produced 90W downstream to a related laptop computer (compared to a rated 96W), and shipped 1.5A charging power off of the front USB-A port, as envisioned. The rear ports fell a little bit small, even so, delivering about .55A, when the rated amperage was .9A. That indicates it will supply fewer energy for charging smartphones and powering exterior devices then you may assume.

From a functionality standpoint, the SD5780T dock done pretty effectively when streaming a 4K60 movie, dropping just a number of frames. Connecting an exterior SSD via the downstream Thunderbolt 4 port in the beginning produced a odd error, where the laptop computer was unable to locate the listing. It has no difficulties when reconnecting it in the foreseeable future, nonetheless. Copying two.5GB of information throughout the downstream Thunderbolt 4 port to the laptop computer, when streaming, dropped a body or two but devoid of apparent stuttering—a easy functionality, and what you would hope to see.

Our summary? The SD5780T achieved our anticipations, and then some. The value, although, presents us pause. If you can pay for $350, Kensington’s SD5780T Thunderbolt 4 Dual 4K Dock is well worth it. Normally, search our list of the most effective Thunderbolt docks for a less expensive different.
