Each are excellent for what they’re: a compact Thunderbolt 3 dock that gives a really targeted variety of ports, in a configuration that received’t take up a lot of your desk.

(Kudos to Kensington, by the best way, for utilizing the devoted 10Gbps USB emblem to establish the sooner ports.) There are additionally a pair of older DisplayPort 1.2 ports for a pair of shows; be aware that the dock powers a pair of 4K shows at 60Hz if linked by way of Thunderbolt. In any other case, the dock will energy two 1080p shows at 30Hz, in line with the handbook, in case your laptop computer simply has USB-C.

Another docks, just like the pricier Plugable TBT-UDZ, supply the choice of utilizing both DisplayPort or HDMI cables to connect with your show. Kensington’s method is ok, provided that many 4K shows ship with with each HDMI and DisplayPort choices. Simply be sure you personal the correct cables. The dock carried out as anticipated, taking part in again protected content material on Netflix and never dropping a single body whereas streaming 4K video whereas linked to ethernet.
Whereas the built-in USB-C and USB-A ports are rated to offer 5V/1.5A per port (for 7.5W charging of smartphones), they equipped 4.8V/1.37A to our USB energy tester, for a complete of 6.61W. That was sufficient to cost, however not quick cost, a Samsung Galaxy S20 smartphone. The dock by no means will get too scorching, even underneath load.
This dock comes with a three-year guarantee.
