Will Charging Cables Ever Have a Single Standardzed Port? (msn.com) 175
The Atlantic complains that our chaos of different plug types "was supposed to end, with USB-C as our savior."
But part of the problem is what they call "the second circle of our cable hell: My USB-C may not be the same as yours. And the USB-C you bought two years ago may not be the same as the one you got today. And that means it might not do what you now assume it can."
A lack of standardization is not the problem here. The industry has designed, named, and rolled out a parade of standards that pertain to USB and all its cousins. Some of those standards live inside other standards. For example, USB 3.2 Gen 1 is also known as USB 3.0, even though it's numbered 3.2. (What? Yes.) And both of these might be applied to cables with USB-A connectors, or USB-B, or USB-Micro B, or — why not? — USB-C. The variations stretch on and on toward the horizon.
Hope persists that someday, eventually, this hell can be escaped — and that, given sufficient standardization, regulatory intervention, and consumer demand, a winner will emerge in the battle of the plugs. But the dream of having a universal cable is always and forever doomed, because cables, like humankind itself, are subject to the curse of time, the most brutal standard of them all. At any given moment, people use devices they bought last week alongside those they've owned for years; they use the old plugs in rental cars or airport-gate-lounge seats; they buy new gadgets with even better capabilities that demand new and different (if similar-looking) cables. Even if Apple puts a USB-C port in every new device, and so does every other manufacturer, that doesn't mean that they will do everything you will expect cables to do in the future. Inevitably, you will find yourself needing new ones.
Back in 1998, the New York Times told me, "If you make your move to U.S.B. now, you can be sure that your new devices will have a port to plug into." I was ready! I'm still ready. But alas, a port to plug into has never been enough.
Obligatory XKCD.

The RJ-45 plug has been the Ethernet standard for a while now. Cables come in every color you can imagine. Today, you have no idea if you’re plugging into a Cat3 port or a Cat6 port until you plug in and negotiate the speed. But the point is you can still plug in.

The minimum 10k plug/unplug cycles rating is anyway WELL above any barrel connector would have. And rightfully so, as the leaf springs that keep the connector in are in the barrel connector from the laptop side, while for USB-C they are in the connector from the cable side.
What's more, the ports are on their own board, from the Framework laptop where you just take them out and put a new one in to even the machine that resembles closer a phone nowadays, the Macbook Air. Even there the USB-Cs are on a board that's $10-$20 on Amazon (and probably $1-$2 on Aliexpress and similar) and it doesn't take 2 minutes to get in and replace it (yes, it's just some screws, no glue no nothing). And as I've had this discussion before YES, probably there are machines that are harder to repair than the Macbook Air but the reason to avoid them would be just that, not how the power connector looks. Heck, even the cheapest Dell Inspiron - we're talking high $200s for a fairly decent machine, including a 120Hz screen(!) - which is WAY less than what costs a freaking KEYBOARD for the better Apple/Samsung/Microsoft tablets (yes, they're well into $300s!) - still has one of the USB-C ports on an I/O board.

Unfortunately reality disagrees with you. We have barrel connector charges floating around still that are 10+ years and don't have any issues while the USB-C connectors ages like there's no tomorrow. Broken casings, no communication with the docking station it connects to and wires starting to get exposed where the cable enters the connector.

Unless something has changed recently, I'm pretty sure that any USB-C cable that does not pass the data pins is absolutely not spec-compliant.
Specifically, the USB BC 1.2 spec [emlogic.no] spec allows data pins to be used with resistors to tell downstream devices that they can draw more than 500 mA power. Without passing data pins, that won't work, and the cable will either have to lie and say that it can draw the maximum power (which could overload the charger) or not lie (which would cause a non-PD-capable device to

Very nice and handy feature to allow USB-C to allow pass-through of different standards.
Dell BIOS Warning for USB-C ThunderBolt Charging Problem
I will say that stupid Dell start-up my laptop into a full-white background BIOS screen when I connect the new laptop to an older dock

My old USB-A cables do not work.
The real problem is the imagination of engineers. The ob-XKCD is wrong. It should read "let's create the standard that will be the definitive standard" 2 years later... "our old standard is not definitive enough".
Strange charging cable (Score:2)
One end doesnt fit into the USB-C port of my Anker charger. Well, it fits, but it just drops out. The other end doesn't fit into my MacBook's charging port. Same thing, it just falls out. At least is safe, since no connection is every made.
Another device that I bought has a USB-C charging port and a USB-A to USB-C charging
When are we going to agree on 48V for DC power? (Score:2)
It's what all telecommunication equipment uses because it's the best combination of safety and efficiency. Surely it is easier just to deal with that than to negotiate voltage and hope nobody ever fucks up.
USB C connectors used for so much more (Score:2)
I had a nice milled Al LED flashlight that used a USB C port to do its charging. Internally there were two 3.7 vdc Li-ion batteries, so it prolly took 9-12 volt wall wart. Of course, wall warts all look the same %^( so one evening I decided to charge it, found what I thought was the right wall wart, and promptly smoked the charger circuit in the flashlight.
This lack of standardization is an issue for non-compute devices and data transfers as well.

There is truth to that. Except for connecting flash storage, anything not ancient for most purposes is fast enough on the data side. Will you really notice/care transferring those 50 photos off your camera or phone took 6 seconds instead of 3? And [typically] anything will work for charging, it just might take a lot longer than expected.
I am more annoyed by USB-C vs. Micro-USB vs. Mini-USB because I have devices with all three. USB-C is far superior as a connector, but that doesn't purge me of the old cr

You notice it if you plug in your laptop while you're working and the remaining charge keeps going down.
The slowest USB 3.0 speed is about 20x the speed of USB 2.0, so yeah, you notice the speed difference transferring files.

Laptops draining their batteries even when plugged in isn't limited to USB though. It started happening many years ago when manufacturers realized they could ship an under-sized charger and pull power from the battery when system load got too high for it. It might have been Apple that did it first, I forget, but Macbooks were definitely affected.
The other big advantage with USB charging is the one cable dock. Plug in one wire and you have charging and 40Gbps data link to run USB ports, card readers, monitor

When I travel what I tend to do is charge my phone from my laptop, and the laptop from the wall with a DIY USB C adapter I made using a "PD trigger" from AliExpress.
The phone only needs to charge at 500mA overnight.

I'm a little surprised that no Chinese manufacturer has come up with a USB C port that can fit in the footprint of common Micro USB connectors, for repairs and retrofitting.

For all practical purposes for most people USB-C is USB-C. A normal person might not notice that they aren't getting the highest speed transfer they could if they used that USB-C cable instead of this one, but a normal person isn't going to care.
Exactly. USB-C is simply a physical connection and pinout spec, with lots of leeway as to what the pins actually do. There is no requirement to carry data or even provide power; although most cables at least provide power at some power level. Manufacturers can use features such as OTG, and thus you need a special cable and that cheap one from AliExpress may not work but otherwise charge fine; leading people to believe the cable is faulty, since, as you point out, "For all practical purposes for most peop
