I wish there are easy ways to figure out the maximum current and wattage supported by a cable. So many cables don't label themselves except on the box!
Note there is a link at the end of the article to a device which can test cables and determine exactly that! But it's a sign of the problem that you need that thing.
With USB-C cables I tend to throw them out unless they are premium cables that cost upwards of $20, I mean I could keep the cheap ones around to charge this or that but cheap cables have this way of going bad, like they are supposed to work if you plug them in either way except they don't, you plug your cheap device in overnight to charge and it doesn't really charge, etc. No way I could trust my wife to handle it.
Personally I think USB got worse in a lot of ways in the 3.0 generation, like at 1.0 they designed a bus architecture that could enumerate 127 devices on a root hub. USB 3.0 doesn't promise anything and ff you start plugging in hubs to your laptop you will hit undocumented limits and find devices start dropping out randomly when you've plugged in several devices and it gives me the heebie jeebies because a mass storage device could drop out. I know mainstream filesytems today are pretty durable but still...
Even the simplest 3-wire cable with nothing but wires in it will handle 45W charging already, which is enough to power my laptop. It needs to be physically broken to not work. If it doesn't, it's usually the device's fault. There are many cheap devices out there that are just USB-C-shaped and don't actually implement the spec, working with some kinds of cables and not working with others.
Personally I have stopped buying cables that do not disclose this information. There are pretty fine alternatives that do, so I see no reason to take gambles.
My only issues so far come from charging protocols rather than cables anyway.
Moreover, stuff like how many watts a cable supports are issues that happen regardless connector type.
Not saying this device is not cool, but one can also get this info easily in a computer, if you find out what to look for. One had presented a utility here some time ago with a menu bar icon showing this information
These PD testers are cool (I thought about buying one), but honestly, for the price of a tester, one can buy 2, maybe even 3 good quality cables and just throw away the rest.
Fair point, I just have oodles of cables (literally 10-20+ per combo of micro/mini/standard-USB-A/B/C <-> micro/mini/standard-USB-A/B/C each) and I like having them all organized by capability so that when I need one I can grab from right bin.
Before getting the tester I just kept buying new "known good" cables whenever I needed one since my cable drawer was just a huge unknown.
