N=1, but my quality of life has greatly improved. Literally all devices I use daily (laptop, phone, mp3 player, Bluetooth speaker, headphones) I charge from a single cable.

I'm still grateful for this unification every time I charge my phone via the laptop charger.

LTT has created true spec cables with the actual spec mentioned on the cables but they can not keep up with demand despite being expensive get sold out as soon as new stock comes in. https://www.youtube.com/watch?v=Hfovjw7Ts_U&t=974s

I have a few of these cables, pretty decent although I think the USB-C ports are a bit too thin? They feel lose in multiple of my devices

Multiple people I know, and myself included, have experience failure of their USB-C port on their phones.

I don't think they are really durable enough.

USB-C is just a connector. A cable can be a USB-C connector USB 3.0, power delivery 3.1 cable, or it can be a USB-C connector Thunderbolt 4 cable, or it can be a USB-C connector DisplayPort 1.4 cable.

IIRC you can also run USB 2.0 over a c port

Do people really not remember the hell of every device having it's own cable which was incompatible with all the others? Going around to a friend's house and finding out, no, they don't have the cable that can charge your phone.

It is a strict improvement to be able to transfer data or charge at degraded speeds, compared to not being able to plug it in at all. Wanting all your cables to end up entirely incompatible just because you don't want to bother checking labels (modern cables come with clear ones, I have ones that clearly say 40Gbps/240w on them) is, frankly, silly.

There is no hell. Just buy a couple of good cables and life is nice

Earlier quoted context omitted.

You can have power-only cable (no data transfer) because the PD protocol does not use any usb data wires.

I'm also happy we have a single connector but, n=1, I have a couple things that will not work with all cables.

I have no idea why, nor have I bothered to find out, I just marked the cables they came with (which are USB-A to USB-C) same as GP did.

Is there a similar one that could test also max data transmission available on given cable?

At a minimum, if plugging it in to a device and measuring waveforms is good enough for your application, you need an oscilloscope with 10 GHz bandwidth or so (don't quote me on that, I don't remember the max speed used by USB). Scopes at that level require a whole lot of R&D and very expensive components so they're really not something you'd want to buy to check your own cables.

If you're talking about reading the e-marker then you can just plug it in to a device and use an app. Google will help you find one for your platform.
