Kindle Paperwhite (12th Generation) Review: A Strong Choice for Everyday Reading

A 7-inch, 300-ppi E Ink reader with adjustable warm light, waterproofing and a large Kindle library. Its biggest strengths are convenience and a polished reading experience; its main limitation is Amazon's ecosystem.

How it works

How E Ink displays work

Microcapsules of charged black and white particles sit under glass. A voltage flips a page. Then the image stays with no power and no flicker. That is why a Kindle lasts weeks and a shelf label lasts years on a coin cell.
