I never knew that USB-C extensions are not allowed for a reason (www.youtube.com)

There is a reason for USB-C extensions not to be part of the standard. They can be bothersome in the best case and dangerous in the worst.

Nice! I’ve wanted a tool exactly like that many times. I’ll back it and see.

The closest I could find before were essentially pin to pin continuity checkers, which are useful for telling if a cable is PD only, 2.0 vs 3.x, or has a line break, but most of those can be eyeballed, otherwise metered. So these just checkers just add precision and speed to something you already know how to do.

The runner ups were the (now ubiquitous) inline inductive energy trackers, because they can tell you a bit more about the gauge of the wires in the cable which can be important, especially high amperage 5v like pi 4.B

But to test quality of shielding for high rate data transfer, DP and PCI-E tunneling, etc., the only option was manually user testing with adequately powerful devices.
