      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.

        Basically like ethernet over powerlines work.

        I imagine plugging a powerbank into itself just causes a short circuit. Detecting that isn’t the most uncommon thing fafaik.

        Just like at work: Forward office calls to your mobile. Forward mobile calls to your office phone.

        Get your work done until everybody finds out and starts wasting your time again 😂
