Connecting camera to Android device - Power supply question

[Nek]

Hi everyone, fresh noob to astro-photography here. 

I am doing research and buying various parts to start astro-photography and I have a question: 

I am getting basic zwo camera asi120, and from the description I see that it has a USB 3 B port with USB 3 connector on the other side of the cable. That USB 3 is connected to the laptop to get the image from the camera. As I understand, that USB 3 will give the camera its power supply to work (correct me if I am wrong here). 

Now, I also read that it is possible to connect the camera to Android device that supports OTG. And once camera is connected I will see notification for OTG that I need to activate and see on the device screen the image from camera (again, correct me if I am wrong). 

In that case of connection to Android, I will need an adapter, in my case to USB C port. So I can either use USB B to USB C cable if I purchase it separately, or to use original cable and use adapter from USB to USB C. 

Now, the main question - if I do such connection, does the Android device supplies power to the camera and is it enough power to activate it? 

Let me know if I am missing something, 

Thanks

I have used a ZWO camera with an Android tablet and it did power the camera OKTablet specs said it wa an unpoweed port but it give enough power to run the camera using an OTG adapter.

Thanks for the answer. 

Did you install a special app to see the image, did you need to select a new input or was it prompted in Camera app automatically?

I just used ZWOs Asicap and saved images to a memory card.
