I stumbled across this sort of fascinating area of doomsday prepping a few weeks back.
https://prepperpress.com/usb/
A nice addition to that, don't just make it a USB, but a raspberry pi. So you'd have a reasonably low-powered computer you could easily take with you.
Not suggesting this one as it seems a bit expensive to me, but https://www.prepperdisk.com/products/prepper-disk-premium-over-512gb-of-survival-content?view=sl-8978CA41
Just built one of these myself. I went NVME M.2 instead of SD Card to avoid data corruption. I know SD Cards are fine if you don't write to them a lot but if you wanna update or add your own stuff, scares me. Plus NVME is just so much faster.
How would you access the info if electricity permanently goes out?
You find a generator, or solar panels, or wind mill, or water turbine, or a bicycle hooked up to a generator.
If electricity permanently goes out then we're in a scavenger situation and it is time to start taking apart things that are no longer necessary to build the things that are.
Pretty much what Sinthesis said; USB power brick and/or solar panels. Both at the ready and tested. Also got a big ass battery backup that will charge off solar panels.
You only need 20 watts of power. One of those dinky fold up solar panels would work. Add a USB power brick for cloudy days.
2W for a RPi Zero with data on a microSD
You're going to need a monitor as well.
I have a PaPiRus ePaper eInk e.g. https://media.digikey.com/pdf/Data%20Sheets/Pi%20Supply%20PDFs/PaPiRus_ePaper_Web.pdf and even though I don't know the watts for a refresh but I assume it's one of the lowest solution you can use.
PS: FWIW if you don't refresh the display can keep the information on for months, if not years.
Eink displays are pretty awesome for this sort of thing, I repuposed a kobo ereader as a household info display and it worked nicely. Those PaPiRus screens look easier to interface with, but a little small for reading wikipedia articles. They'd do in a pinch, but the eyestrain would have me looking for a bigger solution.
Totally, if you want to read or read / sketch then a reMarkable or PineNote would be much better. They'd consume a lot more energy (relatively speaking) but it's a different use case.
at this point why not just use a phone running postmarketos?
You'd first have to buy a phone that can run postmarketos and these are much rarer than I wish they were. Is there even anything new that can run it? Pine64 stopped making phones and said they'll make a new one when they can make it RISC-V.
Fairphone maybe I guess. 4 is listed as a supported device, but someone has gotten it working on 6 too.
Last I checked (3 years ago) postmarketOS drained the pinephone battery in record time :(
Cause if ya wanna go overboard like I did, 1TB of NVME storage, can add with SD Card if necessary. 16GB RAM. Very little learning curve for my part as I use SBCs often. Plus almost every Docker container and program I want works on RPi without any hassle.
There's also more robust guides and community for RPi.
Just my thoughts.
