My computer only has one USB-C port and I want to connect multiple USB-C devices to it.

I have trawled through Amazon but am amazed that I cannot find a single one. There are many hubs that have USB 3.1 USB-A ports but not USB-C ones.

Is there a limitation in the spec that prevents this being possible?

    I've closed this because a lot of the answers are simply "here's one I've found" rather than answering the specific question of "why" and risks further devolving into nothing more than a collection of "pick my one!" answers. A useful answer has been posted, we don't need or want a hardware shopping thread. The question itself is not bad, but it is attracting the wrong kind of answers.

2021:

Thunderbolt 4 docks are now available, which for the first time allow for USB-C / Thunderbolt true multi-port hubs.

For the first time, Thunderbolt 4 will offer docks with up to four Thunderbolt ports and universal cables up to 2 meters in length. – Intel press release

These hubs also seem to pass through USB-C DisplayPort Alt Mode signals, allowing them to be used with non-Thunderbolt devices.

Thunderbolt 4 hubs:

2016-2020:

The chips needed to produce one-to-many USB-C hubs essentially did not exist prior to Thunderbolt 4.

Some of the same complaints are outlined here:

https://mjtsai.com/blog/2017/10/14/the-impossible-dream-of-usb-c/

None of these USB-C “hubs” actually give you more USB-C ports.

There is supposedly news for 2019/2020 that suggests hub chips may be coming soon:

Update (2018-07-30): Accidental Tech Podcast reports on a rumor that next year Intel will finally ship the chip that’s needed for making a USB-C that adds additional type-C ports.

http://atp.fm/episodes/284 (19:10)

We've heard from an anonymous person that Intel is finally releasing a hub chip for USB-C next year. We may not see products based on it until 2020.

  • @pkamb - Do you agree with the most recent edits to your answer?

    @chx - That will get you suspended. Stick to editing your own answer to this question

    I just rolled back the edits @chx has made. The original poster (pkamb) has clearly rolled them back in the past and yet now, with the answers cleaned up here and there being a better focus chx is still violating the basic concept of respecting the original poster’s intent. This is mentioned in a comment here and elaborated on in the meta post about this question and chx is still insisting on pushing this forward “till the cows come home.” To whose value and to what value? Your suspension, chx? Apr 5 at 4:13
  • @chx Please stop this nonsense. Apr 5 at 6:24
  • @chx the reason that I reverted your original edits was that large paragraphs of USB-C minutia + product recommendations are out of place in this answer, which is attempting to provide high-level guidance to the question of if any multi-port hubs exist at all.

Also search a lot and only found one :

The Belkin 4-Port Mini USB-C Hub with Two USB-C

All four ports support only USB 3.0 speed (5 Gbps = 300 MB/sec effective).

However please note:

The USB-C 4-Port Mini Hub does not support pass-through charging and video output to monitor. This hub is only intended to use with USB-A and USB-C peripherals.

Update:

Found a 2nd one from Sitecom the CN-386:

Turn your USB-C port into 3 ultrafast USB-C ports and 1 USB-C Power Delivery Port

  • USB 3.1 Type-C input
  • 3 x USB 3.1 Type-C Output (10Gbps data and 7.5W power)
  • 1 x USB Type-C Power Delivery (100W power)
  • Supports USB SuperSpeed 10Gbps, downwards compatible with USB 3.0 / 2.0
  • Supports USB Battery Charging (BC) 1.2 up to 7.5W (5V / 1.5A)

    Nice. Although I would really like to see a smaller version of this device, i.e. something that I can attach to a phone. Main goal is to connect USB-C headphones and charge my phone at the same time. Feb 13 '20 at 16:27
  • Yeah but doesn't somethink like that work? amazon.com/Splitter-Extension-Smartphone-Converter-JKRED/dp/…

  • Most likely, this cable uses Audio Adapter Accessory mode. Depending on the manufacturer of the phone, this may or may not work. The extra USB-C is for charging only and at 500mA rate only, so fast charging is not possible. Feb 18 '20 at 14:17
  • The USB-C ports are according to the video "USB 3.1 5Gbps" ports (which means that they are effectively USB 3.0 ports) - not perfect but better than nothing.

  • Seeing that Sitecom also has a 1x USB-A (4.5W) int 2x USB-C (7.5W) + 2x USB-A (4,5W), 20.5W total without an additional power input makes the USB power delivery questionable to say the least: sitecom.com/en/usb-a-to-usb-a-usb-c-hub/cn-399/p/1925

I found one with four USB-C ports! The Sitecom CN-385. It only goes up to 5GBit/s, but judging by the (admittedly just two) reviews on amazon, it is more reliable than its big brother, the CN-386, which has Power Delivery and 10GBit/s support.

    i ordered the SiteCom CN-386, where one of the ports is a 100W power delivery port - had to order it from amazon in the UK. But I can't get any display port monitors to work on this hub :(( OSX 10.14.6

    @Tilo I think this hub doesn't support DP via USB-C, just plain old USB 3.1 Gen 1. This could be one of the reasons why few companies produce hubs like these, they lead to quite a bit of confusion. If you want to be sure, ask SiteCom directly.

    Hopefully this works for you, but I deleted my previous answer to this question because pretty much one year later the hub I found started to flake out and cause more headaches than solutions for me. Using a USB 3.1 hub with USB A to USB C cables right now and things are stable. Speed is 5Gbps which is not as fast as 10Gbps, but stability means more to me than speed. And Thunderbolt 3/4 hubs are too expensive and co-dependent on external power sources for my needs. Apr 27 at 17:22

Actually OWC is about to create a solution for this stalemate, but you have to look a step up, both in function and in price. However, given how long we waited all is fine: a Thunderbolt 4 hub.

https://eshop.macsales.com/shop/owc-thunderbolt-hub

It should also support USB-C standard, so it is also an USB-C hub.

  • $149.00 is not the same as $14.90 which is around what most basic USB A hubs cost. Apr 7 at 19:28
  • Quality USB hubs were always expensive. Cheap ones are worth exactly what they cost (not much).

  • A $29 USB hub is a fine quality hub. $149 to just have basic USB connectivity — without a need for Thunderbolt — is a waste of money. Apr 9 at 1:12

So far, I’ve found a few hub chips that support USB 3.1, which can find us some hubs:

  • this forum post mentions the 3.1 chips VIA VL820 and Cypress HX3PD. The former seems to be in production use, I couldn’t find anything at that stage about the latter.
  • I also fount the 3.2 chip Realtek RTS5429, which seems to be used in exactly the following products:

  • The first one also says Charge up your devices at max speed with up to 2.4 Amps of power delivery. but power delivery can't be measured in amps since the voltage can be varied... hmm... still, proper usb-3 usb-c ports is a step in the right direction!

  • You’re right, this review says that it doesn’t actually have Power Delivery or Quickcharge. Disappointing. Jun 11 '20 at 16:00

The Dell WD19 (just plain WD19, not the more expensive WD19TB) has two USB C ports, one of which is DisplayPort alternate mode capable. It provides 60W charging to non-Dell laptops (and 130W via proprietary means to Dell laptops). See the WD19 Userguide specifications.

As with all such products, buying one from eBay is significantly cheaper. Also, Dell has standardized its AC chargers so even if you get one without an AC adapter, any 7.4 mm plug Dell adapter works with it.
