The maximum charge voltage for a lithium cell is 4.2V while USB will provide 5V. It may work for a while, it may fail in a safe state or something gets hot and burns.
actually the powerpack have varied output (4.5v5a - 12v1.5a), I’m not planning to use this for real I just wanna see if it work or not since the powerpack and phone battery output the same DC current

Then this is not safe.
