It seems to be working, but the phone is expecting a 4.2V or 4.35V max input and USB is 5V. Maybe that power bank has a lot of voltage drop or a poorly regulated output so the voltage is lower.

this powerbank can output varied output (4.5v - 12v) and it’s a fairly high quality powerbank

USB-A will be 5V though.

It supports those, but voltages other than 5V will only happen when an appropriate handshake happens. Just a USB-A cable to bare wires has no handshake and will be 5V.
