I think as it know the voltage some sort of software protection could be implemented to avoid this.
Or I get a bad one, you tell me.
I don't know what happened with yours.
I have also bought three, one for my family member, one for my friend and one for myself, but so far only one has arrived, others are going to arrive in a few days.
However, I have tried different Type-C power supplies on this one, also a 20V capable one and a power bank, and also a regular 5V charger.
It worked with all of them, but the power bank was only able to go up to 9V and I have only experienced low voltage warning when I have connected to a regular 5V supply which is as expected.
...but it is still working, I don't think regular 5V should cause any problems.
It may had some faulty component(s) or maybe your power bank could make a voltage spike which caused the internal circuit to burn out.
I have read there was a protection diode which is not applied on production devices and absolute maximum rating of a component is 24V, so a voltage spike may cause problems.
However, FUSB302 has an absolute maximum rating for VVBUS voltage as 28V and recommended operating voltage of 21V and the IC may be the source of the problem you have... I think.
