@sigmasternchen I do need SD card storage though, because I want it fully offline.
@Em0nM4stodon @sigmasternchen I don't know the rest, but at least my old Kindle (a present, and still woks, and which I keep 100% offline to the point that both my APs refuse connections from it) can get books via USB, so my impression is that the rest too. In particular, I use Calibre to transfer ebooks to it.
@Em0nM4stodon @sigmasternchen are you sure? Books are memory light but content heavy. I have a kobo it's easy to load books whenever I need and it can easily hold more than I can read in a year.
@Em0nM4stodon @sigmasternchen ReMarkable has a small version of their notebook/e-reader. It works completely offline.
@max_power Hmm no dark mode and quite expensive but that's pretty close to what I'm looking for! Maybe I'll give it a try. Thanks for the discovery!

An expensive DIY version of Xtink X4 Touch (updated).
The Open Book Touch has too low a resolution screen, too slow a CPU and about x2 overpriced.
The mainstream makers don't do less than 6" 4:3 and SD card slots are rare.
But a 32G Flash ereader stores about 18,000 ebook novels.
The TCL Nxtpaper phones are better than eink Colour and only poorer than mono eink if the eink front light is off because there is enough ambient light.
All ereaders work off line and via USB.
