Is there a cheap, reliable tester that someone can recommend that will test multiple USB cable types (A, micro & C)?

I'm not so sure about cheap. All the cheap ones I've tried have been pretty flaky, and ended up in the junk bin. I picked up this guy for work: https://bit-trade-one.co.jp/en/adusbcim/ and it's been pretty good. That was a while ago though, and some of the cheaper ones might have caught up.

Only $30, but with tariffs and shipping I assume it adds up.

We are lucky we don't need to transfer (so much) data over these. Just imagine looking for Gen 2x2 or Gen 2 SuperSpeed charging station.

No, we need to transfer a lot of power instead. So those with 800v cars need to be mindful to visit certain charger stations/types over other ones in order to get a fast charge, vs relying on the car to boost it from an older station.

Just imagine you would visit such charging station and it would support the fast charge. But only the connector, not the cable.

So? Is there a hard limit on just one “Type” in the formal name?

Not if your aim is to confuse your costumer

Spec committees arent rigid automatons, they can clearly decide on say USB Type C-123 for practical implementation if they chose to.

The ones in the article do have handles, but they are on the sides and so almost not visible.

I coded this as an exercise https://apps.apple.com/app/cable-detective/id6765963737?mt=1... - reads everything it can about the plugged in cables and devices, feeds it to Apples internal AI. In the latest version it even doesn't crash the computer anymore after rapid plug/unplugging action.

There are several apps that do something similar and the biggest issue is the marker on the chip it's interrogating doesn't guarantee the cable can actually provide that. The maker can program whatever they want into that chip and the devices will just negotiate and determine what they're actually capable of achieving anyways.

yeah, the app tries to tale this into account and gives an "unverified" label on stuff that is doubtful

This is better, USB Type C Grade 123, or USB Type C-123, or just USB-C-123
