The 2021 Paperwhites all have USB-C charging, but the Signature supports wireless charging. Still, if you want to save some cash, just clean out your backlog you can remove a book from your device without deleting it entirely from your Amazon account. If you mostly listen to audiobooks, you may want to go for the Signature, since those tend to take up more room. That's a big difference, but you can still read and store a lot of books with 8 gigabytes (around 5,000). The Signature has 32 gigabytes of storage and the Standard has 8 gigs. Its faster page-turn rate means there's no delay while you read. The screens are brighter overall at their max and have adjustable warm lighting, but only the Signature can auto-adjust that brightness to your surroundings-we think that should be standard across all models. We tried the Signature Edition ( 8/10, WIRED Recommends), but all three have bigger, 6.8-inch screens with smaller bezels.

The step-up, waterproof e-reader went from one to three models, and they rival the more expensive Oasis. We think most people will like the Paperwhites the best.
