I think it's most likely, that you only fry the adapter. Maybe you
didn't fry it, because there could be a inbuilt circuit, that shuts
down, when the input voltage is outside the range. Plug the adapter
again and measure the output with a universal volt meter.
If you don't have access to measuring equipment, try with another
adapter with input voltage 230 V and 5 V DC 2 A or more output,
before you go out and buy a new one.
