FYI
Is it just us or does the stack of books on this picture look like the WinRAR icon? Anyway, back to the matter at hand. If you’re going on a long trip somewhere and don’t want to drain your Kindle’s battery, why not get a portable reading device?

A portable reading device is an optical-scan, multiuse hardcopy file imprinted on dedicated, crashproof media with minimum system requirement of basic literacy. It absolutely does not run on batteries or gasoline, and you don’t need to plug anything into anything to transfer data from the device to your brain! In other words, get a book.
