These have their place, though. The obvious example is public charging cables, which at least have had PoC for exploits.

I had one of those power bank cases, and it was absolutely awesome for extended battery life. It was always there with the phone, it was just a bulky case (which did not bother me), it tripled or quadrupled my battery life, and it was about $20.

Sorely missing that it’s not available for my current phone (Pixel 8a).

Ignoring the question of whether this is real, you’d probably find out when you can’t find them at the store, order from your supplier, etc.

Basically, it would get noticed earlier in the supply chain.
