How to choose a suitable wall adapter for power bank?

I have a P brand power bank having following input ports:

1. Micro IN: 5V 2A 9V 2A 12V 1.5A
2. Type-C IN: 5V 3A

I have this wall adapter from H brand (intended to charge H brand phone) which offers following output:

1. 5V 2A; or,
2. 9V 2A
   

What I understand is, when I am using the USB Type-C cable which comes together with the phone, my phone is quick charged. If I use other USB Type-C cable, my phone is not quick charged.

If I were to use this wall adapter + USB Type-C cable to charge the power bank via Type-C IN port, is it suitable? (I am asking from pov of voltage and ampere)

I have been using this combination to charge the power bank. But the power bank become bloater and bloater. I wonder which step I did incorrectly.
I understand I might have to dispose it (correctly) and I would like to avoid any wrongdoings for my next power bank.
