Local Area FTP (lemmy.ml)

Hey everyone, I hope you are well.

I recently purchased a TP-Link Archer C7 from a thrift store for 4 dollars and converted it into a pineapple router using a firmware build that someone made based on Open-WRT for testing and educational purposes, and it it has raised a few other thoughts and interests.

I have two questions.

Is anyone aware of a software available through F-Droid or otherwise which can be used to turn a phone into a temporary access point serving FTP for file sharing purposes? I think it would be handy to be able to share files to several people in proximity and I would imagine turning a phone into a mobile FTP AP would be something that has been done. If anyone is aware of any such project, I would be highly interested.
For running such a thing whether it be through a phone or a router, is anyone aware of a mobile power source which can fit in a backpack easily and power a 12 volt 1.5 amp router for ~10 hours?

I would love to be able to have the ability to basically have a backpack that acts as a mobile NAS that serves FTP/SFTP.

Thanks.

1.5 A for 10 h is 15000 mAh, at 12V. Current powerbanks can do that. Here is a redmi one, specs says it can do that, 20000 mAh, 12V is the maximum: https://www.mi.com/global/product/20000mah-redmi-fast-charge-power-bank/specs

Buy an usb-pd 12V cable, one end of the cable is type c, the other end is standard dc coax. The cable has a chip inside, so it will always ask for 12V from the power source, it's like 5 USD, I have one for a similar usecase, works perfectly. They work only if the source can send the required voltage, if a powerbank can only send 5V or 9V it cant convert it up to 12.

It should look something like this, make sure the voltage is correct before buying:
