HP sells two variations of this Thunderbolt G4 Dock: the 4J0A2AA (this design) and the 4J0G4AA, which we haven’t analyzed. The change is that thelatter includes a “combo cable” that materials up to 280W of electric power by way of the mix of a Thunderbolt 4 cable in addition a barrel charger, for HP workstations. The 4J0A2AA provides up to 100W to the host notebook through the Thunderbolt cable—still among the highest we’ve witnessed. Even then, there were no thermal issues at all.

HP’s squat little plastic Thunderbolt G4 Dock (three.nine x three.nine x two.7 in) feels a lot additional reliable than its rated 1.68 pounds would indicate, and it sprouts ports to all sides: a 10Gbps USB-C port capable of 15W charging on the entrance a 5Gbps USB-A port on either aspect as well as two far more on the again, all able of seven.5W out. The back again also houses two DisplayPort 1.four ports, an HDMI two. port, and a USB-C 3.2 Gen 1 port developed for video clip. We only tested this dock with two 4K/sixty exterior shows, but it’s capable of driving 3 4K/sixty shows delivered you have a DisplayPort one.4-able laptop computer with Screen Stream Compression, or DSC.

There’s also an ethernet port able of 2.5Gbps, as effectively as another Thunderbolt 4 port outlet. The ports are crammed together with hardly adequate place for DisplayPort cables or USB keys, but a few of the outdoors ports are marginally skewed outwards to deliver more place, a good touch.

This business-oriented Thunderbolt G4 Dock features vPro aid and the energy button/LED can be utilised to change by itself on and off —but only when linked to supported HP notebooks. The throughput is excellent, assembly expectations on all of the ports. The entrance USB-C port shipped 15W of electricity, as the HP’s manual says it should—although, weirdly, the dock missing link with the displays for a handful of seconds when a smartphone was connected. We be expecting a firmware improve to remedy these issues, and we do not think about them dealbreakers mainly because of the charging capabilities of the other ports.

When notified of our results, HP reps explained they could not reproduce our results. In any occasion, HP features a a person-yr minimal warranty in situation the trouble manifests by itself once more.
