Is there a way to connect the terminal to the PC and debug it with logcat without power supply?

It's just as the subject says.
I would like to observe the behavior of the Android application under development when the power supply is low, but when I connect the terminal to the PC via usb, the power supply is inevitable and I cannot achieve my goal.
(Application Summary: Application that keeps retrieving external sensor data for a long time.)

I searched the internet for what we call "data transfer only usb" (I actually bought about two), but I haven't found a cable that can actually achieve only "data transfer".

Is there any good way?
For example
·Another application that allows you to retrieve information that appears in a specific application logcat that is running offline
·How to connect offline with Android studio and do the same thing as logcat

I would appreciate it if you could let me know if there is a good way.
