USB-C Has Finally Come into Its Own
wired.com
wired.com
Ironically, one of the reasons I went with Android instead of iPhone last time I bought a phone was that I could use my MacBook charger with it.
That should be fine. There's a protocol for the charger and the device to communicate and decide what power to charge at.
Unless explicitly negotiated by both ends, every USB-C charger outputs the same boring 5 volts as classic USB, so the headphones should charge just fine.
The switch dock demands 39 watts, which implies 15 volts, but the switch itself will negotiate any voltage when standalone.
In fact, I am doing it right now.
Output on the adapter reads: 5v@1.5A/15v@2.6A
The only time things break is when you attach a broken charger that outputs 9 volts onto a wire that's supposed to be doing 2 volt signals.
Also some devices don't support anything else but USB-A to C cable that comes in a box. That's why I returned JBL Charge 4 and got Anker Soundcore Motion+. Much crispier stereo sound at expense of some base.
Unfortunately a lot of devices are out of spec like the Nintendo switch which can be damaged by an in spec charger.
So you would need compatible cables to make fast charging work, and then it will only fast charge up to 80% and then slow down.
USB-PD is the standard for power delivery and Apple (and Google) both rely on that, so if it's USB-PD compatible it'll support the quickest charging it can handle.
Sure, you have 1 more cable to throw in your bag but it's not a big deal.
This is a change (like Flash) that Apple forced and should be credited for.
Well I am not happy with the change, because I don't want to be the hostage in that plan of "changing the future". I want my stuff to work and get things done. I don't want to struggle to change the future. I don't want to force everyone. I want stuff to work.
Apple providing USB-C ports in addition to USB-A sockets would have been great. Apple removing USB-A is a major problem for some of us.
Once peripheral makers etc are already have in house experience and knowledge with USB C thanks to their phone departments, it makes far more sense to release USB C peripherals even at the desktop level, so the removal of USB A ports from the MBP likely played a very small to no role in the transition.
Even if the MBP had both USB C and USB A ports, peripheral makers would likely have preferred making their peripherals USB C compatible.
I'd really like this, but I don't know if it'll ever happen. The situation, as it stands now, is a mess:
The Raspberry Pi finally got USB-C, but they botched the implementation. As did the Nintendo switch. Even with phones and audio, there's like two different kinds of dongles and you never know which will work? https://youtu.be/Ly-bSBHOSIo
Not to mention that there's a ridiculous number of standards that a USB-C device can support, but you have no way of knowing what by looking at it physically. Power delivery? Not on most non-high-end Windows laptops. Data? On most, except the Raspberry Pi? QuickCharge? Sometimes. Video? Only with some phones and laptops. Not most non-high-end devices.
You always have to look it up, it's a huge mess.
There was also a myriad of charging options around the launch of the iPad. It was a hit or miss gamble with chargers, cables and devices. Maybe you'll get 1A? Maybe not?
USB-C is a complex standard, but the chipsets and processes are improving and this pain will be a distant memory - just like all those USB-A pains we had.

To take an example, BLE is really quite good, and works reliably.
I bought my kids two identical headphones. How do I make sure each headphone is connected to the right device? It's infuriating.
(It's possible to change the name of all Apple bluetooth devices, but why other vendors don't copy this feature is something I just don't understand)

For the hobby (/etsy/small-run-on-ebay) market there's also the fact that the average hobbyist doesn't have access to soldering equipment that is good at BGA parts.

I have to clean the USB-C port on my Android phone every couple of months otherwise it won't charge because the cable won't completely fit into the port. A thicker port means now more fibers and dirt can get in. This never happened to me with micro USB or lightning ports.
The Nintendo Switch has a USB-C port which means you should be able to use any USB-C to HDMI cable or dock to charge it or connect it to a TV, right? Nope. You can only use the official expensive dock or USB-C cables. Otherwise you can brick your Switch. [1]
I bought a cable for TB3 to connect an SSD to my iMac and instead of getting 40Gbps I only got 480Mbps... my fault for not reading the small print, but having the same connectors for different protocols is not a smart idea either.
So I bought a real 40Gbps TB3 cable and then discovered whenever I plug anything on the TB3 ports of my iMac the CPU temps increase by 10ºC which makes the fans audible pretty much all the time. I opted for using USB3 which uses pretty cheap cables, is fast enough, and doesn't heat up my iMac.

AIUI, the way this all shook out (that's an early story) is that you can stick any USB-C charger you want into the Switch directly, and it'll work fine without bricking anything. However, when a dock gets involved, it gets more complicated. The easiest and safest way to remember the matrix of safe vs. unsafe is "use the official dock directly and don't do anything else". Technically there are other safe things in the matrix, such as using the USB cable with a proper resistor in it, but it's all too easy to get any other such policy wrong, and not usually worth it.
Not that you're wrong to complain about the bricking issue. It's broken. It's just not quite as totally broken as some of the early articles thought. (For obvious reasons, nobody was too interested in conducting careful experiments to nail down all the variables.)
Another issue is that not all USB-C cables to HDMI work either because I think I read somewhere that Nintendo didn't follow the HDMI specs.
It's not USB-C's fault of course but I've never seen so many issues with USB1, 2, or 3.
This happens regularly to the lightning ports among my family&friends. "My iPhone keeps stopping charging" "did you clean out the lint with a toothpick?" "Oh"
> Otherwise you can brick your Switch
The bricking was happening due to a faulty third-party dock that was sending 9V on a 5V line. Nothing to do with the Switch itself. You can use any old USB-C charger with the Switch, as long as it's not faulty.
https://www.reddit.com/r/NintendoSwitch/comments/ckaiiv/an_e...
An argument may exist for lint etc being harder to clean out of a USB-C port once it had made its way in there, but haven't witnessed it myself yet.
Anecdotes can be given all day, but I would suggest it's a potential problem for any port of similar size being placed in pockets and bags.
But you cannot use any USB-C to HDMI adapter.
https://www.reddit.com/r/NintendoSwitch/comments/7qgy9d/has_...
From what I could find after an hour of digging through USB specs is that that line is actually supposed to use 2V signals. (Though it's possible I misread.) So the faulty dock is even worse!
For the switch to tolerate 6V on that wire is already a healthy buffer. How hard is it to keep things 5V or less on the data wires of a USB device?
It's very stupid that TB3 cables aren't required to support USB 3, but thankfully that should go away over time with USB 4.
You are never going to prevent the existence of charge-only or similar cables, since they're a lot cheaper than running four high speed data pairs.
Raising the minimum to 3.0 wouldn't fix the problem, just make it sting slightly less. And you can't require the best speed on everything because that's expensive and 'best' keeps increasing.
In my mind the real crime is that you can lay out a bunch of cables and they can't be sorted from slowest to fastest. There are weird broken gaps, like cables that support TB3 but only TB3. Also that the labeling is awful. There should be a clear max speed icon on every cable.
You're lucky. I just did a quick poll of the 12 iPhone users near me, and 8 of us have cleaned out our lightning ports in the last 3 months. 2 just cleaned out now as they realised this is what was causing their charging problems.
I haven't had a single issue listed here in any of my own systems or when working as desktop support.
Aside from being a fragile and poorly designed physical connector, the state of protocols that can be run over it is a disaster. My grandmother definitely will not be able to troubleshoot why her devices don't work properly together when she uses a USB type C cable to connect Thunderbolt devices. I suspect this will be the same for many other users.
While having a ridiculous number of different connectors isn't great, I think it would have been reasonable to at least have different connectors for power, data, and video (even if they were all part of the same spec, and just keyed different to help end users figure out what to plug in where).
I would also have really liked to see a solid core connector. Apple Lightning is a good example of what that would look like -- there is no tiny wafer inside of the device-side port to crack, and both the port and connector are much more durable. Not that I think we should all use lightning, but it's an example of a reasonably well designed connector in my view.
Finally, I think the fact that so many vendors have failed to properly implement the spec is a sign that it's a bad spec. Raspberry Pi and Nintendo presumably have competent engineering departments. By and large, nobody had difficulty getting microUSB right.
Out of curiosity, what issues have you had with the charger/port of the Switch? I've had a Switch for a couple of years now, and the closest thing to an issue I've had with charging is that I can't use a less powerful charger (e.g. the one for me phone) effectively with it, but I basically knew that going in.
I guess if there is a possibility for that it is very low or I am very lucky.
I've just assumed those "warnings" are there for liability reasons because these companies didn't test their devices' charging capabilities across all possible USB charging devices.
I think the issues are more with poor quality chargers than the switch itself.

There have been problems with 3rd party doc which is partly Nintendo and partly 3rd parties.
https://arstechnica.com/gaming/2019/08/heres-why-nintendo-sw...
It seems to me that the outer metal sheet on the connector will prevent a "wrong" angle on the wafer.
Linus Tech Tips actually tested 10000 USB-C insertions: https://www.youtube.com/watch?v=OqtNleXhTRE
Spoiler: USB MicroB failed at 8000, USB-C was still working at 10000
All it takes is for one fragment if debris to get wedged in the wrong way, and now that port on your expensive device is broken irreparably.
It may have that durability during normal use, but I doubt that these tests account for being shoved in backpacks or banged around in potentially dirty environments. Most people I know don’t use their laptops in sterile labs.
There are very affordable (relative to the cost of a new laptop) online businesses specializing in this exact problem. But a skilled hobbyist (possibly with some advise from Youtube) or decent phone repair shop can do it too.
It's actually not that hard (put kapton tape around, remove old using hotair and tweezers, clean with flux and wick, solder new with iron or hotair, a compatible solder or paste, and lots of flux. Clean with spray/brush). Assuming you can source a replacement part, but between Digi-Key/Mouser, eBay and AliExpress that's rarely impossible.
What do they mean ? I remember charging my phone (or even a mp3 player) from my laptop using mini USB and later micro USB like 8 or 10 years ago.
What's new is that you can now use a laptop charger to charge a phone.
Maybe in a few years when USB-C is more mature, and manufacturer know how to place safeguards in devices so you can't fry it by plugging the wrong charger...
Would I do it with a no-name charger or cable or an older one? Hell no.
This was true for USB micro B chargers, I've had one go pop maybe a desk width from my head one day. It was true for laptop chargers, which have caused their share of fires. So USB C is not new on this. If you use high quality products it'll probably be fine.
1) not that many people have four USB-C devices they need to plug in at once (unlike USB-A),
2) it'd probably be super expensive and in some cases impossible to support all the abilities of USB-C across 4 ports, leaving only some small subset of capabilities available on all four and maybe forcing you to not use some of the ports at all if one or two of them have higher-end capabilities and you're actually using them for that. Experience is probably confusing and frustrating at best—and expensive anyway.
I guess negotiating the bandwidth and power delivery would be pretty complex
Besides phones and laptops there are not many USB-C devices out there yet. And you don't connect phones and laptops to hubs (as a guest, not a host).
Then I guess the title "USB-C Has Finally Come into Its Own" is a lie.
Apple has been shipping laptops with only USB-C since 2015. Many people rely heavily on dongles and breakout boxes. A USB-C hub would be welcome even at a steep premium.
My guess is that all of the tech that tunnels through USB-C would be really difficult to hub or to share. Which is why the closest thing I've seen to a hub is a passthrough plus a USB-C for power.
https://www.amazon.com/Belkin-Linksys-B2B153-04-BLK-4-Port-D...
But I would point out that the linked device has 1 USB-C Power Delivery pass-through, 1 USB-C data port, and 2 USB-A ports.
Nobody has yet shipped a USB hub with more than 1 USB-C downstream data port.
It was bus-powered, so I'm pretty sure it was simply a bunch of USB-C ports that offered no more than USB 3.0 and that didn't support USB-PD.
Can't seem to find it anymore.
It is highly likely any such hub would be a USB-3.x hub only but wouldn't support power pass-through properly, you wouldn't be able to connect your monitor to it, etc.
For example, let's say you have a USB-C hub with 4 downstream ports and two USB devices plugged in. At least one of these is a 10Gbps USB 3.1 device. You plug in a USB-C -> HDMI adapter. Which of the following happens (and how does your grandmother diagnose the problem)?
1. Nothing. 2. The three existing devices detach from the bus and re-enumerate as USB 2.0 at 0.480 Gbps 3. The three existing devices continue to run as 3.0 devices, but only at 5 Gbps 4. The three existing devices continue to run as 3.0 devices at 10 Gbps
Explanation:
1. The hub does not support USB alt modes, so when an HDMI dongle is plugged in, the dongle is ignored.
2. The HDMI dongle is a passive alt mode device, requiring the use of all 4 high speed lanes. The other downstream devices are routed the internal USB 2.0 hub.
3. The HDMI dongle has an active Displayport -> HDMI converter inside, and uses only 2 of the high speed lanes, leaving the other 2 for USB 3.0 data. Since the other peripherals use the 2x 5Gbps USB 3.1 mode and only 1 lane is available in each direction, they revert to 5Gbps
4. Same as #3, except that the peripherals use the 1x 10Gbps USB 3.1 mode, so they continue to operate at 10Gbps with a single lane.
Ok, now 3 ports are occupied and you plug in a pair of USB-C headphones. What happens now?
1. Nothing 2. Your HDMI dongle stops working 3. Everything Just Works
Explanation
1. USB alt modes don't cover the case of a USB Audio Accessory and a Displayport accessory. Since you can't have both, your drivers ignore the new device
2. Same as #1, but your drivers prioritize the new device
3. Maybe your hub secretly has an audio codec inside, and is able to sync and source analog audio to any downstream port.
Bonus points: Ok, now what happens when you chain USB-C hubs? What happens when you try to plug in multiple HDMI adapters? Multiple audio accessories? When things don't work, is the problem the hub, the peripheral, or the drivers?
1. Plug the HDMI adapter: almost nothing. The HDMI adapter enumerates as an USB 2.0 "billboard device". The operating system can read the descriptor from this device and present a pop-up explaining "you have to plug HDMI adapters directly". This is because, as far as I know, USB hubs can't pass through alternate modes (except for the new USB4 alternate mode, but that is less of "pass through" and more "the hub is a USB4 device itself").
2. Plug the USB-C headphones: it depends on whether they are analog headphones using the "audio accessory" mode, or digital headphones presenting as an USB audio device. If they are digital headphones, it's the "everything just works" case; if they are analog headphones, it's the "nothing" case (unless there's something in the specification I missed where a hub can detect the "audio accessory" and warn the host, in which case you might get the pop-up explaining "analog headphones are not supported by this computer, even if you had plugged them directly").
Things change a bit with USB4. In the particular case where the HDMI dongle is an active DP to HDMI converter (which is probably the most common case, since from what I've seen computer support for the DP alternate mode is more common than the HDMI alternate mode, so most dongles will cater to that case), and the hub is an USB4 hub, it'll work as if it had been connected directly, since USB4 can tunnel Displayport (together with PCI Express and USB 3).
Users (even technical users on Hacker News) keep asking for a "USB-C hub". What do you think they mean by that? "I want to plug in all my USB-C crap" or "I want to plug in all my USB-C crap, except video dongles and some[1] audio dongles"
All the use cases for an everything-except-alt-mode USB-C hub are already met by existing USB-A hubs[2].
[1] "And please don't give me an easy way to tell which headphone dongles will work ahead of time. The surprise and anticipation of seeing whether it works makes every plug-in event feel like my birthday."
[2] Okay, okay, you do need USB-C connectors for 20 Gbps USB bandwidth. But I've never actually seen a 20 Gbps USB host, device, or hub in the wild.
I wanted to address your point about the "correct" answer, because it's actually not so simple:
The billboard spec allows for a device to be both a DisplayPort 4-lane and a USB 2.0 device (This isn't theoretical--I have such a device in front of me. It's a passive DisplayPort + 2 port USB2.0 + microSD "hub").
The HDMI adapter I hypothesized in my second scenario is a passive HDMI adapter. You're correct that passive HDMI + USB2.0 is not possible, but substitute a passive DisplayPort for passive HDMI here and the idea is the same.
In the third scenario I am hypothesizing an active 2-lane DisplayPort to HDMI adapter (These are also not theoretical--this is how the Apple "HDMI Multiport Adapter" works).
The hub I hypothesized for scenarios 2 through 4 (which does not exist) is one that would be smart enough to do the following:
1. Recognize the video dongle's billboard
2. Send the host a "fake" billboard for "DisplayPort 2 lane + USB 3.0" or "DisplayPort 4 lane + USB 2.0" (as appropriate)
3. Re-configure the downstream USB-C as USB 3.0 or 2.0-only ports (again as appropriate)
4. Route DP to the dongle (perhaps via an internal DP -> HDMI converter, if the hub has one), Route USB 2.0 or 3.0 to the internal hub, and route the hub to the downstream USB-C ports.
I don't recall if rewriting the billboard is allowed per the USB spec (I think it isn't). But you can see how it would be possible for a hub to support alt-mode routing, even if the spec doesn't formally define it.
The alternate mode discovery is initiated by the host, so the only way the hub could change which alternate modes it supports would be to disconnect from the host (unplugging all the devices on it, which would be particularly bad if some of them were storage devices).
(Also, I believe HDMI alternate mode with USB 2.0 is possible. The only alternate mode I know of which changes the meaning of the USB 2.0 pins is VirtualLink, which uses them for USB 3.x instead.)
It's mind-boggling how the entire industry fucked this up so badly.
I would say USB-C has come into its own when every corner store or uber car has a usb-c charging cable standard.
Apple is in a tricky place because there are so many accessories in the world that work with Lightning. Customers would be pissed if they had to use dongles for all of that stuff they already own.
The 30 Pin connector existed for 9 years before Lightning came out in 2012, so we still probably have a few years before they consider abandoning it.
I imagine by then, USB-C will actually be the universal solution that everyone wants.
Part of me is actually expecting Apple to abandon cables altogether and just provide wireless charging/syncing.
Eh, they were brave enough to do it for the 3.5mm jack, I don't see why they couldn't do it here. So I think the real reason is they want to continue to sell $40 lightening cables, or whatever they cost now.
> In Apple’s case, the hesitation at least makes some sense. As long as USB-C compatibility is more tangled than a late-stage game of Twister, it will remain anathema to Cupertino’s mantra of “it just works.” USB-C can still feel more like "it works, just not always how you were expecting." Apple already achieved USB-C’s space-saving and reversibility benefits seven years ago with the introduction of its Lightning cable. And in those seven years, an expansive ecosystem of Lightning peripherals has emerged, all of which would head straight for the scrap heap with a jump to USB-C.
And adding an adapter onto lightning plugs is less invasive than the issues with removing the headphone jack.
Edit: So would anyone like to explain how any of that is such a bad contribution it deserves a downvote? I'm always surprised when a comment gets silently downvoted, it's never something where I expected any downvotes...
(not suggesting that’s why you were downvoted, just clarifying the timeline of the ports)
Lightning devices were shipping end of 2012.
USB-C design was finalised end of 2014.
Maybe the development started too late for Apple to involve it in their plans? But that would have been a really rapid pace. Overall it looks a lot like this was Apple fussiness.
Apple was probably planning on that as well, but the AirPower fiasco has probably set that plan back quite a few years.
To be fair that didn't stop them dropping the legacy iPod dock connector for Lightning in the first place.
Just look at the mess of variants for USB: https://en.wikipedia.org/wiki/USB_hardware
While I've only had to deal with 2.5-3* transitions for my Apple devices so far.
* Apple of course did cause their own mess transitioning away from Firewire while keeping the 30-pin connector:
- 30-pin Firewire data + charge
- 30-pin Firewire charging only
- 30-pin USB, no firewire charging (Remember all those Bose dock/car 30-pin adapters).
- Lightning port transition.
In this case, Apple's proprietary ports ended up feeling a lot more universal.
However they’re more likely to come up with one with no cables at all...
Only battery pack with 2 usb-c seems to be the ZMI Ambi: https://www.amazon.com/ZMI-PowerPack-Ambi-USB-C-Power/dp/B07....
[0] : https://www.anker.com/products/variant/powerport-atom-pd-2/A...
It'll do 60W from one (laptop), or 2x30W and is fairly compact. So I amusingly now have lightning to USB (damn you Apple), and also bring a single USB-A to USB-C adapter sometimes (e.g., for a Fitbit charging cable).
"Wait... there are no USB ports on this thing? How the fuck am I supposed to plug anything in?! My flash drives, my camera, my microphone... anything? Seriously?"
Welcome to dongle life :-(
2019, still don't have a single thing in our house to plug into a USB-C port, except adapters. Probably reach the end of 2020 in a similar state. Just bought a new 4TB portable HD that's USB-A (3.0), because USB-C wouldn't be able to plug into anything but a new Macbook, without an adapter.
Instead of converting USB-C to DP/USB-A/HDMI, the dongle should be converting DP/USB-A/HDMI to USB-C.
It's about upgrading the older perpherials instead of downgrading the new devices.
For example, the dongle is instead fixed to my DVI port on my monitor. Now my monitor has a USB-C socket, instead of my laptop or phone having a DVI socket.
It reduces bulk and now I truly only have to use USB-C cables everywhere. If someone knows where to find dongles like this I'd be very excited.
USB Type-C receptacle to USB legacy adapters are explicitly not defined or allowed. Such
adapters would allow many invalid and potentially unsafe cable connections to be
constructed by users.
Why did they opt for a connector with a tongue that could break on the device?
The Lightning connector seems to be superior because it does not have a piece that could not only break, but is a real PITA to fix.
Turns out the Macbook chargers although looking almost identical to the Macbook Pro chargers can only provide enough power to run the Macbook Pro but not enough power to run and charge it.
Not sure how non-technical people are ever supposed to realize or understand any of this.
Hmmmmmmmmmmmmmm.
The cost of implementation is really high & relies on way too many chips to achieve anything. Few SoC have USB-C built in.
It's gonna take a decade before this becomes at all regular. It'll be in products, but it's still exotic to work with, & only doable along very narrow paths. That's the pace we're running at.
But otherwise I prefer USB-C to all previous alternatives so far.
micro USB: january 2007 to august 2014 (7 years, 7 months)
USB-C: august 2014 - ? (5+ years)
I hope we keep increasing the lifespan of the "suggested" mobile-device USB form factor, to increase convenience and (slightly) reduce environmental impact.
USB-C's form factor might stick around longer, but its compatibility problems are going to be much worse.
Lightning Connector: September 2012 - ???? (7+ years)
https://www.anker.com/ca/products/108/216/desktop-chargers
Checking on Amazon I see at most 2 USB-C (with nothing else so not useful)
This one has 2 USB-C
https://www.anker.com/products/variant/powerport-atom-pd-4/A...
This has 2 USB-C and 2 USB-A. Apparently it’s out of stock on amazon right now though...
One of the USB-C cords powers the fan beside my bed!
As it is I have a USB-C to USB-C cable for my Macbook for it's power supply, another for my Mifi, another for my Pixel. But I have no power supply that can charge all 3 so instead I have to have 2 cables for every device. One when use it on it's own. Another for each when using a single charger. If I hadn't sold my late 2018 iPad I'd have 4 USB-C devices needing 8 cables.
That's not "Come into it's own" that's "Still in frustrating transition from USB-A era"
I could list a bunch of other cables and adaptors I need because USB-C is not yet "come into it's own".
I’m hoping Apple stick with lightning.
* A fairly capable soldering iron [2]
* Studio grade lighting [3]
* Prusa i3 3D printer [4]
* Emblaser Core Laser Cutter
Each of these devices come with their own power supply unit, most of which are bricks at least twice the size of the Apple's charger, while most likely of lower output signal quality (e.g. higher ripple). It'd be great if all that waste could be replaces with a USB-C port!
That's why I'm currently working on a PCB kit which can be programmed to require a certain voltage/current from an upstream USB-C power supply [7]. It can then be used as adapter for (or embedded inside) devices that don't have USB-C power input. I'm hoping to sell the kit in the future. I'll be getting rid of my power bricks one by one while making them more portable with things like high power car chargers [6].
I'm also working on an upstream USB-C power supply (as a kit) [8] that can take any input from 10-35v and provide up to 100 watt output (which is currently rare).

But all the attributes I mentioned could be irrelevant to many. If you carry a 30 liter bag around, double the size of charger won't make a difference. If you're powering lights, output ripple doesn't matter much and so on.
