I wonder by what method it does that? put out a pulse code on the power out and look for it? Some USB cables don’t actually carry the data lines through, so.
You either have a ping before connecting and if you get a response don’t do it. Or you send some high frequency wave additionally to the power. You can detect that signal and then stop accepting the power.

I imagine plugging a powerbank into itself just causes a short circuit. Detecting that isn’t the most uncommon thing fafaik.
Next technological revolution will be breakers in powerbanks
What about all those usb handshakes? It think it will just drain itself with heat and damage the battery slightly while doing so.

Basically like ethernet over powerlines work.
Something something ground loop detection, maybe.
