In short: If you need those adapters and extensions YOU should check if the max power is compatible, because the USB standard won't do it for you.. USB C extension cords should be part of the standard as a specific use case of an USB HUB, and that would allow every single one of those adapters and extensions... but again the "USB IF" let us down...
It isn't only "unsupported configuration" for the adapters, cables, but also potentially a bad implementation. Female to Female adapters can be created as "USB hub". Not having more ports of the hub exposed would cause no problems, so your "2 port hub" type female to female adapter could work okay, safely and can even advertise itself and capabilities as a hub. No reason to have a separate specification for these kinds of adapters as they can be seen as a 2 port hub. I am sure that a 2 port hub can be also certified... An otherwise "illegal" extension cable can be created as combining a cable and the above mentioned 2 port hub. Both the cable part and the hub part can work, and even if they are permanently connected it can be safe. If there is a safe a compliant way to design a device for this functionality and they choose an unsafe and noncompliant way, that is an issue. As EU made mandatory to use USB-C charging for many devices as they hoped for an "universal" standard, we would see a scenario where people assume they are universal. People who assume it is safe to charge their devices with any USB-C charger, with many cords, etc. might create fire hazards due to non-compliant implementations. Physically incompatible chargers at least forced people to think if their device is compatible with their device. A false sense of security, safety and compatibility is dangerous.
@@quiescentcurrent they do have some use, though it rarely happens that I need them, last time I needed one was to force a tablet in bootloader modus, by NERFING a cable to oblivion, so it had barely enough power to boot, but not enough to quickcharge it. had to use like 2+ cables, and 5+ adapters, to kill off any quick-charge feature, and make the cable 5M long.
What about micro USB to USB-C adapters? Should those also be avoided? I just ordered some to get the convenience of charging any type of device with my cables, especially my 3m long micro USB cable, as my smartphone is still micro USB, while my headphones need USB-C. Must I use entirely different cables for them?
Surely, the non-conformant M-M connector has a role in testing the extension cable you used, as it wouldn't cause misrepresentation of the capabilities ( as the compliant one presented the cable as USB4). Or have I missed the point? Great video by the way, very helpful.
If the "extension" cable has no USB chip, but is just a passive cable, it won't be what's responding. Look for another Quiescent Current video on USB-C "extension" cables.
I don't understand the logic of the adaptor declaring what it is. Surely the idea is that the identification should be one end device identifying itself to the other end device over the whole connection. So a straight adaptor no chip connection in the adaptor would allow that. The one with the chip is deception, as either item connected believe they are connected at 40gig but the cable being used may not be. Even worse, it is also possible that only one of the items (devices) may not be 40g high wattage yet the one putting out the high wattage thinks the other device is capable of taking the output when it may well not be it may have been made prior to the signalling. If the chipped adaptor can read the earlier device, then it could be ok, if intelligent enough it can override the possibility of one seeing the adaptor chip as the other device, But I see no logic here for a chip on the adaptor, that should be up to the devices to negotiate their own connection and the adaptor allow that to be done. I do see a need for the straight through ones to be rated for high current and labelled with the actual power charge wattage, not a silly code that can be misconstrued, as USB connections have been for several years now with totally rubbish nomenclature for versions and generations.
The USB crowd are idiots, did they think nobody would want or make extenders and adapters? Before USB-C adapters & extenders were fairly common, so why on earth did they think this would all go away. USB-C is kind of a complete shemozzle as most users have no idea what a particular port on say a laptop is capable of, or what lead they need (or the fact there is an difference between leads) A USB-C extension cord should just act like a USB-C hub, a hub with only one outlet, that should not be hard. The EU says standardising on USB-C will reduce waste from all the cables that went before, NO it will just add to it as people plug something in and it does not work, so it must be faulty, so into the bin it goes....

I have some of those female C to C adapter [mostly PANEL versions]
they work quite nice, but I won't be using it for anything higher than 12V 2A.
Probably the best idea ;)

Really great content! Thank you very much!
'legal' or not, where can I find the shortest male plug to male plug passive 'cable' ?

Should be fine, that's in-spec. Samsung even included them before in their phone boxes
how about a usb c male to usb c female splitter
Key word is interest foundation it’s not actually a law it’s more of a suggestion
Thank you for your great content! Is there any safe way to create a USB-c extension?
What about those connectors with the power LCD readout? I see them all over and have wondered if they are safe.

Good point, I've tested everything beforehand in different combinations and it was working as shown

Thank you!
what’s the point of this? when would you ever use this kind of adapter

Strange that these exist
so, in general, i better stay away from cables/adapters with a c-female port, right?

Why did they bother with USB-C anyway? Just one more incompatible standard, as if there aren’t enough of them already.
Power delivery.
@@MePeterNicholls So what’s next? USB-D, delivering enough power for an electric fire? We used to have things called power cords for that.
