For the very first time in my life, I am looking at Raspberry Pi for a small project. I've only ever worked out of Windows laptops, and I am not a technical person either, so need some guidance.

I've read the Raspberry Pi official docs, and other blogs, and I am fairly confident about setting up Debian Bookworm on a RPi3B. I know basic Python, so I can handle the coding part of my (simple) project too. What I need guidance on is the power supply. I need to place the RPi in an area that does not have a power socket, and pulling wires is going to look ugly. Would using a 9V battery pack be a viable alternative? I am thinking of something like this:

Will this work? Are there any other options? Or, are there no options except a wrired power supply?

How about using a 10,000 or 20,000 mAH power bank?

I agree with @SmartCat. Raspberry pi needs 5V supply and a 10,000/20,000 mAH powerbank would be a better solution.

Also, any reason to choose RPi3B? You could use RPi Zero 2W (cheaper and smaller size) or more powerful Raspberry pi 4/5 depending upon if you need lesser computations or you need a more powerful device respectively. Do take note of the peripherals on the RPi device that you choose: (HDMI/MiniHDMI/MicroHDMI) for monitor connection, microUSB/USB-C port for power supply and number of USB ports.

This was an option I hadn't thought of! Thank you

This sounds like a noob question, but, how often would I have to power down the RPi and charge the powerbank?

Reason for choosing RPi3B is I want to attach the RPiTouchDisplayScreen to it (my project is: build a digital photo frame that can display image files from a USB as well as shared folders on laptops on the same home network). I wasn't sure if the Touch Display could be mounted on a RPi Zero. For handling the operations on the RPi itself, I plan to use the RPi Connect software. So, the peripherals that I need are: one touch display and one USB drive.
