I post this from time to time - you can get hand cranked USB chargers for a couple of bucks. The build quality is OK, or you can make your own easily enough.
The advantage of the Kindle is it is an entire library in something smaller than a book. Useful when storage room is an issue. It is a good way of expanding your library, though printout, and bound books are recommended for the really important stuff.
There are many books you want and need available for free through several universities sites. Books written in the late 1800s, early 1900s, which is where your tech level for most aspects of life is going to be.
One thing I always recommend, bookwise, is a GOOD vegetarian cookbook or two. If you have a garden, you are going to have veggies to go with your stores. Meat is going to be rarer in a real SHTF scenario.
