My MacBook Pro 15" from mid 2015 is dying, so my boss (“finally”) ordered a (custom) MacBook Pro 2019 which hopefully arrives in a couple of weeks. This means I’ll have to migrate from USB-A to USB-C and maybe some other ports as well.
I currently use:
1x mini-DisplayPort (for first external monitor)
1x HDMI (for second external monitor)
1x Thunderbolt (for Ethernet adapter)
1x for several hardware reference boards (data cables are all USB-A)
I’m using the Belkin Thunderbolt 3 dock. Basically because it was in the online Apple store at the time I ordered it. That was convenient. And I saw it as a sort of seal of approval by Apple (not sure if that’s the case though). And this one offered enough power for the MBP (15"), so I could do with one cable to the computer.
It works fine. And actually, apart from the number of ports and/or the placing of the ports on the device I don’t think there’s much difference between the vendors.
I haven’t compared this one to others. But as I said, the Belkin seems to do its job pretty well.
Which one are you getting, the 13" or the 16". The difference, in this case, may be important because the 16" can require more power than most TB3 docks can deliver. (I have a 16" MBP and use my older Belkin Thunderbolt 3 dock with it and it works just fine, but under heavy load, the system will slowly drain battery.)
Oh, I will need one more USB-A port than posted above. I’m currently working from home (due to the Corona Crisis) using my personal wireless keyboard, but at work I have a wired keyboard with a USB-A connector.
This is the only one that I’m aware of that puts out more than 85W: https://plugable.com/products/tbt3-udz/ but I have not done an exhaustive search. I find that 85W is fine for me except under the highest GPU+CPU loads.
