There is a promo atm for anyone looking for a portable dock for the Switch…
This thing can also plug nicely to any laptops which can provide up to 4K display at 30fps and 100W USB-PD.
I ordered but haven't got a chance to test them out but the reviews seems good.
They also guarantee that it won't brick your Switch but a bit unclear with the process of replacing your Switch if does become bricked.
As a display dock, this does not deliver 4k 60fps unlike those MacBook docks that can use 2 simultaneous USB-C port.
Good dock, works well. Spring mechanism is a bit flaky, so the top cover can get jammed if the spring is not pressed precisely - make sure to press evenly in the middle to raise/lower the top. (A bit annoying when it activates in your bag, so better to store it where it won’t get pressed!)
If you have no use for the CoreDrive (eg. laptop hub), then Gulikit portable dock kit is an alternative that looks pretty good. You can transplant an official dock into the shell if you’re worried about bricking, or get the one with Gulikit’s own board in it (not sure how safe). I would buy the Gulikit one, but I already have a JumpGate, one of those cheap generic portable dock shells (haven’t transplanted yet), AND a Genki Covert Dock on the way…so II probably don’t need any more docks! lol :)
