> No. One charger. One cable. One standard.

USB-C being "one standard" is a bit of a stretch. It is the Unintuitive Serial Bus, after all. Most will charge. Some faster than others. Some will supply data with 2.0 speeds, others 3.0, yet others will do more. Some will only work with the other devices they came with. Few cables will tell you which is which, unless you have a tester.

There were two major flaws with the rollout of USB-C, none of them technical:

To have unmarked cables. This should have been explicitly forbidden by spec as non-compliant. Today unmarked is the norm, even with premium brands. And the few ones that actually mark their cables have their own markings (which I assume is because the official logos are so incredibly bad). So now instead of wondering if the charger will work, you’re wondering if the cable will work.

Secondly, the USB-C rollout was only successful on the sink (device) side. Almost all cheap gadgets come with an A-to-C cable, and chargers and PC ecosystems are very biased on the A ports for the host side. This created an awfully ugly side effect: devices are not always compliant with even basic charging. Since C-to-C should not have live 5V line active at all times, these devices don’t charge at all. I think they’re missing that resistor that tells a compliant charger to make it live. But in either case they only work with A-to-C.
