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?

  • Go to shopping.google.com and search on "USB 3.1 Gen2" USB-C hub – K7AAY Dec 5 '18 at 23:11
  • The cable you've linked won't let me plug two USB-C thumbdrives or anything with a built in USB-C cable. I've done your google search also but nothing comes up (I think google reverted to shopping UK though, so perhaps not available in England?). Is it really supply/demand or is there a technical reason? I thinkI read that USB C is limited to 2 metres of cable length... – NibblyPig Dec 6 '18 at 10:02

    It seems to defeat the point of USB-C peripherals if they all need to be used with an adapter (my pc only has one usb-c port, and it's located on the rear of the box which is a real pain), still my original question stands - why! It's like saying I'd like to use two usb 2 drives and being told to use a serial port converter or something to use an unintended socket... – NibblyPig Dec 6 '18 at 16:05

    Is there a way to charge multiple laptops which have USB-C charging with one hub? – trinalbadger587 Jun 1 at 20:23

The chips needed to produce one-to-many USB-C hubs essentially do not currently exist.

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.

    they better hurry up on this since it lowers the usability of the standard ... – haemse Mar 19 at 22:23

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:

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. – Sergiy Belozorov Feb 13 at 16:27
  • Yeah but doesn't somethink like that work? amazon.com/Splitter-Extension-Smartphone-Converter-JKRED/dp/… – Lonzak Feb 17 at 13:45
  • 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. – Sergiy Belozorov Feb 18 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. – Robert Mar 1 at 12:45
  • 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 – plaisthos Apr 30 at 22:58

    I found this one as well, but it has two one-star reviews on amazon, so I'm not too sure if it can be trusted. – iFreilicht May 18 at 15:31

One of the only shipping one-to-many USB-C hubs I've seen is in the LG UltraFine 5K Display, introduced by Apple alongside their USB-C / Thunderbolt 3 MacBook Pro in 2016.

A single Thunderbolt 3 cable (included) provides up to 85W of charging power to your MacBook Pro with Thunderbolt 3 (USB-C) ports. And three downstream USB-C ports (5 Gbps) offer additional connectivity and power to compatible devices and accessories.

This part is unique in that it is not a multi-port "dock" but a true one-to-many "hub".

It would be interesting to see if this part could be harvested from a damaged display and used independently.

four USB-C ports, one cable to the Mac

  • This is actually a Thunderbolt to USB-C hub. These are quite common. – Jason Jul 25 '19 at 17:45

    @Jason quite common? Please post any other Thunderbolt to USB-C hub that adds more than 1 extra port :) – pkamb Jul 25 '19 at 18:28
  • 3
    The Elgato "Pro" dock has 3 (one with TB). The Dell WD19TB has 3 (one with TB, one with DP). – Jason Jul 25 '19 at 19:24

    Regardless if it's common or not, the fact it's over Thunderbolt protocol and not USB protocol makes it an invalid solution to OP's problem. – udlp Jul 31 '19 at 17:35

    They're also not really simple one-to-many hubs, but very expensive "docks" with multiple other ports. The LG display is unique in that it is a true "hub". – pkamb Nov 20 '19 at 0:09

Here are some. I'll update this list as I find more.

Please feel free to add to this list. I'll only add products that offer something different, better, or cheaper than other products listed here, so as not to create a list of garbage.

    How strange that the two USB-C ports are USB 2.0 ! – NibblyPig Oct 23 '19 at 15:08
  • Baby steps... baby steps. ;) – zylstra Oct 23 '19 at 15:22

    It uses two USB-C ports to give you two USB-C ports, so not sure how this helps? – Chris Apr 23 at 22:02

This question is old, but I have just found a solution that works for me and I believe works for others looking for such a beast… The IOGEAR GUH3C22P:

It has four ports total: USB-A and USB-C ports.

  • The USB-A ports are 3.0.
  • But the USB-C ports are 3.1 Gen 2 with power delivery (PD 3.0) pass-through up to 100W (85W max with 15W going to the hub itself).

This is exactly what I was looking for for my MacBook Air! Works quite well and speeds from external USB drives are really great.

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! – NibblyPig Jun 11 at 14:45
  • You’re right, this review says that it doesn’t actually have Power Delivery or Quickcharge. Disappointing. – flying sheep Jun 11 at 16:00

My search pulled up these, altho I haven't pulled the trigger:

    These are all $300+ "docks", not simple USB-C hubs. And even then they only give you a single extra USB-C port. – pkamb Jul 25 '19 at 17:40
  • I found this $50 guy aliexpress.com/item/32845466699.html (there are several similar items with just different labels). It is not actually split, you got 2 USB-C: one for power delivery, one for data. So this dock consumes one USB-C and provide one USB-C, plus some USB 3. – orcy Sep 3 '19 at 4:04
  • the caldigit will actually give you 3 ports, two usb-c and one tb3 port. But as USB-C hub it is extremely expensive – plaisthos Apr 30 at 23:03

I found the following product "USB C Hub, Wakio 12-in-1" on amazon that add two additional USB-C ports. However, both ports are USB C 2.0 and not 3.0; so, the speed will be magnitudes slower.

Product showing two USB C ports in addition to the third USB C for the main power source.

  • Is that even valid in the USB spec, giving USB2.0 speeds only, on USB-C connectors? – nyov Aug 31 '19 at 3:20
  • 2
    Yes, it seems it's valid(up to spec) for a USB Type C connector to only support USB 2.1 speeds. As per Wikipedia "A device with a Type-C connector does not necessarily implement USB 3.1, USB Power Delivery, or any Alternate Mode: the Type-C connector is common to several technologies while mandating only a few of them" . I did get excited when I saw the product but was disappointed as I saw the specs. – Fari A Aug 31 '19 at 6:04
  • USB 2.1 doesn’t exist. – Ramhound Sep 3 '19 at 3:02
  • Sorry, yea, that was a typo – Fari A Sep 4 '19 at 4:36

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 Jun 23 at 0:54
  • @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. – iFreilicht Jun 27 at 13:43
