Suggestion: add a field for HDMI or Thunderbolt video. I have devices that will only work with HDMI like ChromeBooks and Samsung Galaxy phones (you can plug them into a screen and use them like a computer). I also have devices that will work with thunderbolt like my Mac and Dell laptops.

Awesome work. Having just gone through this for my company, I'd recommend a few valuable bits of information: - Thunderbolt 3 support filter - Power delivery capability (usually 60W-100W if at all) Both of those are valuable for mac shoppers.

I’ve got a carbon x (6th gen) and an iPhone X, I think what you want would work for me too. This is what I’m thinking of: https://www.amazon.com/Anker-Charging-PowerPort-Intelligent-... If someone happens to have experience with this, share your thoughts please!

I purchased a

Waiting for it to arrive.

Actually all those hubs are almost all equal: they support usb 3.0 and differ very little. Just buy Anker (upgraded) and you will be fine. Different story for usb 3.1 gen 2. There’s only one hub currently and it’s Sony UHS-II. (And even this one can support 4K only in 30 FPS)

Needs to filter whether it can show HDMI 4K at 30Hz or 60Hz. And related to that, for video, it’s possible to have 2 4K 60hz through or one or none. Also filter whether it’s one USB-C connects to computer or two USB-C connects to computer. With two USB-C connected to computer, can pass through more types of USB to accessories. Finally, it doesn’t show matches that I know are matches. // I buy these to test, but don’t…

> Needs to filter whether it can show HDMI 4K at 30Hz or 60Hz. And related to that, for video, it’s possible to have 2 4K 60hz through or one or none. I don't think they'd bother, because none of these docks can do it. USB-C 3.1 inherently can't support a 4k@60hz display, due to bandwidth limitations. And it certainly can't run two of them. You'd have to jump up to a Thunderbolt 3 dock for that sort of thing.

You can do 3840x2160@60Hz (and 24bpp/8bpc) over USB Type-C on newer displays. DisplayPort Alt Mode over USB-C using DisplayPort 1.3/1.4 can support 4K + USB 3 Gen2 on one cable.

I want a USB-C hub that's just one USB-C in to multiple USB-C out. Why is that so impossible to find?

Cypress has a chip out for this: https://www.cypress.com/products/ez-usb-hx3pd-usb-31-gen-2-h...

It has one USB Type-C in with 3 USB Type-C out plus 4 USB Standard-A out. One of the C outputs supports downstream charging. Should just be a matter of time until hubs using this chip are widely available.

One of the things that blew my mind was that in the USB-C spec, you can't have a male to female cord, but I was only able to find two hubs on amazon with a detatchable cable.

Why you ask?

I have a mac and a PC on my desk, and i plug my kb,mouse, and headset (usb sound card) into the hub) and just swap one cable instead of three to game. If you have a better solution that has hub/kvm -> usb-c for the mac, i'm all ears.
