Recently I’ve come across a couple of USB cables of Chinese origin (what else).
Cables that are a real innovation in my view. Carrying just regular USB Type A or Micro USB connectors, they can be plugged in both ways!
Micro USB
Here’s the Micro USB version. Notice the symmetrical shape of the connector:

So it’s easily plugged in in both directions, here’s the proof:

And it isn’t charging-only, also the data lines are properly wired so that the data transfer is possible. You can buy one, for example, on AliExpress.
USB Type A
This one has a Type C connector at one end, which is on itself symmetrical, but the cunning Chinese managed to make the conventional USB A plug at the opposite end also two-sided. It’s really unbelievable:

And here it is in action:

I got this cable also on AliExpress.
So one might wonder why aren’t we using these just everywhere? That’s a perfect solution to unravel the infamous USB superposition problem:

Why indeed. ■
