My only concern with this law, is that what happens when USBC is no longer the best option. Idk how to express what Iβm saying but what if USB-G ends up being 1000x as fast. Does this law allow for chargers to evolve and if so, how? I admit I havenβt looked into this but Iβve been wondering about it.
Iβm 99% wireless these days so I wouldnβt be surprised if chorded chargers are largely on their way out, but Iβm still curious.
Manufacturers are allowed to add supplementary charging standards on top of USB-C PD, and the commission is required to review the landscape every 5 years to see if a new technology is better than USB-C that should be adopted in the future
https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=uriserv%3AOJ.L_.2022.315.01.0030.01.ENG&toc=OJ%3AL%3A2022%3A315%3ATOC
Awesome! I knew by commenting someone educated would come along. Thank you very much.
It's like when I make it rain or snow by washing my vehicle! I'm giving you part of the credit for it being future-focused...
And they're using recommendations from the USB consortium, which is comprised of all the large manufacturers in the world, so it should always be up to date during the review process.
Controversial opinion: I wish this wasn't the case. So many different proprietary protocols, most of the time you'll still need a specific adapter, and in some cases even a proprietary cable to utilize the full speed, and nowadays most devices come without the adapter.
And there's even PPS in the PD spec allowing to request for a specific voltage rather than something in an existing list.
But I do also have some personal grievances here:
Mi TurboCharge - This may be something based on PD, but still being something separate. I don't know, but I do know it requires more pins than USB-A has. 5 pins. Somewhere I read this is connected to a CC pin in the USB-C connector. But no, they did not use USB-C, they used USB-A, with an extra pin. Only shortly before the phone died I finally figured out why it wasn't charging as fast as expected - I wasn't using their proprietary cable.
My current phone's interference (?) with Qualcomm QC 2.0 - Somehow when using a cable with non-perfect connection on QC-compatible adapters, when I move the USB-A connector, it starts triggering 12V mode until it finally shows overvoltage error and slows down to 7W. QC 2.0 is how my USB tester identifies it. This is a MediaTek-based device, so I don't think it would support QC. The original adapter uses PD and some 11V 6A thing with unknown protocol. Perhaps that is where the problem originates, I don't know what data it sends down. But testing with OTG adapter on the original brick it seems the protocol needs the extra pins of USB-C to work properly.
I've had 3 phones that supported some fast charging, so far 2 of them made it into a confusing mess. Had they all used just PD it would have been a better experience.
I agree, but at least requiring USB PD, as it's written, will at least give you 240 watt USB-C charging if they offer higher than 240 watt charging through a proprietary standard
USB-C doesn't have speeds, it's just a connector type. USB 1, 2, 3-3.2, 4 etc. is the protocol responsible for speed. You can have a USB-C connector with any implementation (except maybe USB 1). It can even do DisplayPort stuff.
So for USB-C to become irrelevant we need to come up with a better connector form factor. Which is unlikely to happen soon. But also, same thing happened with USB-B Micro connector (colloquially called micro USB), it was designated as a standard (but Apple managed to get an exemption) and manufacturers had no issues moving to a better connector, which is USB-C.
On the downside, you canβt tell what the port supports by just looking at it.
Even with this graphic, I still don't know what they support. Is circle-20 also 20gbps? What is the speed when there's no number? Do the non-DP ones not support displays at all? And there appears to be no such thing as USB4-DP?
And good luck getting your grandmother to identify any of this over the phone. "Is it marked SS-subway diagram-20, or circle-20-subwaydiagram? Yes it's etched gray on slightly different gray, go put on your strongest glasses first, grandma."
My phone doesn't have any kind of marking anywhere on it so I'm guessing it's USB DP
Googling for it, my phone (pixel 9 pro fold) has USB 3.2, so it shouldn't be able to drive a DP display
Was wondering about thunderbolt. Found this, which I interpret as
usb 4 40 = thunderbolt 4
Wow what a marketing ~~scum~~ trick to show all compatible older generations as separate products
I liked the magnetic apple connectors.
I hate Apple though.
The plug will be the same, bet money. There are already several sorts of USB-C. And think on this, the USB-A has had the same shape for going on 30-years.
This, USB-C is just the connector shape. USB-A is the standard square plug everyone knows, USB-B has several different ends, some more well known than others. The full sized "printer/hub" one, mini-B and micro-B which more people know. USB-A to A cables aren't common, more akin to an Ethernet crossover cable, so you're almost always going to see one of the B connectors.
USB-C is just the newest plug design, the actual cable and communication protocols have changed numerous times over the decades. USB-C might have been introduced alongside USB 3.0 and the massive increase in charging and data speeds with the new standard, but they are not exclusive.
The most obvious example is probably the iPhone 15 and 16, both had a USB-C plug, but the devices only supported USB 2.0 protocols.
I believe USB A-to-A cables actually violate the USB spec and should not in fact ever exist. They definitely should not exist as a straight-through cable (although obviously they still do in reality) without any active electronics in the middle. Male A plugs are solely for connecting to a host device, and the entire purpose of the spectrum of B plugs in their various guises is specifically to make the other end of the cable that goes into the endpoint device different. The point is that you are not supposed to be able to directly connect two hosts together like that.
A straight through dumb A-to-A cable would connect the +5v pin from the host device directly to the +5v pin on the device on the other end of the cable. If you did this between two host devices (i.e. two computers) it is certainly possible that Bad Things would happen if the designers of both devices did not account for this type of stupidity. The only way one of these can be valid according to the spec is to omit the power pins entirely.
That said, I have a particular flashlight that came with exactly one of these naughty cables: A straight through male USB A-to-A cable with no smarts in it whatsoever. The flashlight charges via a USB-A port which is exceptionally bizarre, and I suspect the reason it does so is because it can also act as a power bank and the manufacturer was too cheap to include a type C or micro B or whatever port for input and a separate type A port for output. But now I'm stuck having to use the moronic cable it came with (which is also only like 14" long) without much hope of ever finding an alternative or replacement...
micro-B SuperSpeed is always a good one to surprise people with.
I have a portable hard drive that uses this. I haven't bought a new cable yet, limiting me to USB 2 speeds. Bleh.
I had not thought of this good point.
If you bothered to read the article, you'd notice that the charger was chosen by the manufacturers a decade ago in a summons by the European commission. If Apple had complied to do what they agreed to do back then, this law wouldn't exist. But they got whiny and litigious. So, instead of an at will standardization program, the EU decided to make it mandatory by law, to shut Apple up, and anyone else who wanted to forcibly refuse to comply. The cool thing about European law is that nothing is written in stone. Not even constitutions are considered sacred, unlike in the Americas, and can be changed at any point or amended as long as proper procedures are followed. There's nothing, ever, preventing the EU from calling another commission of tech companies to choose a new charger, if a better one ever shows up.
You should verify this, but I think there is like a consortium of sorts made up of tech companies that pick a standard that they all must follow. So in the future, itβs possible for them to pick a new standard, and then after a transition period everything would be required to switch (though of course you could still continue using old devices, they just can no longer be sold new).
Law does not forbid having multiple charging ports.
