We had something like e-readers and they didn't need recharging as they were made out of dead trees. But each one held just one book, so you had to take a bunch of them to the bathroom with you.
This reminds me of the time I checked out all the Dune books from the library, they were all hardbacks and the stack was nearly 2 feet high. The librarian was like, "You're not going to read all that before they're due" She was right but she let me check them all out anyway.
