Unplugging power bank usb safely [closed]

Solution 1:

A pure power bank only uses the power pins on the USB connector. If the device doesn't respond to queries from the USB controller with a device type (storage, HID, etc), then the OS (Windows) doesn't know or care that there's a device there. So no "remove hardware" option is available.

So yes, you can just plug it in and unplug it as needed.

Solution 2:

Because there is no solid-state drive to corrupt, you don't need to worry about the safety of the power bank or corrupting it. It's just power based, and the "remove hardware" option is just to ensure there is no data exchange going on while you remove the drive, which is what could potentially corrupt a drive.
