Kindle E-Reader Basics: What Is a Kindle?
A Kindle is Amazon's line of e-readers (electronic reading devices) that use E Ink technology to display text and images. First launched in 2007, Kindle revolutionized digital reading by creating a screen that looks and feels like paper while offering the convenience of carrying thousands of books in a single, lightweight device. For the latest hardware and bundles, explore the official Amazon Kindle store.
Kindle Devices vs. Kindle Apps
It's important to distinguish between:
- Kindle Devices: Physical e-readers with E Ink screens designed specifically for reading
- Kindle Apps: Software applications for smartphones, tablets, and computers that provide access to Kindle books
While both allow you to access Amazon's vast library of ebooks, Kindle devices offer a superior reading experience with their paper-like displays that don't emit blue light, exceptional battery life (weeks rather than hours), and reduced eye strain during extended reading sessions. Many users also find it helpful to compress PDF files before transferring them to Kindle to save storage space and improve loading times.

- • Advanced E Ink technology with crisp, paper-like display
- • Weeks of battery life on a single charge

2025 Improvements
