Project Help-Arduino Nano 33 IOT

Hello, I want to collect data from the accelerometer of the Arduino. I can easily collect the data from my sensor. Due to my project, I dont want to get the power supply from my pc, I want to use powerbank for the power supply.

I had already run the WIFININA and SimpleWebServer codes but when I plug the arduino to the powerbank, the arduino ide software got error about "could not find the port" what should i do ?
