Kindle Wireless Reading Device Features

Battery Life of Up to One Month
A single charge lasts up to one month with wireless off. Keep wireless always on and it lasts for up to 3 weeks. Battery life will vary based on wireless usage, such as shopping the Kindle Store, web browsing, and downloading content. 

Charge Via USB
Kindle ships with a U.S. power adapter and a micro-USB cable for charging your Kindle from a computer USB port. The U.S. power adapter supports voltages 100V-240V. 

Get Books in 60 Seconds
Whispernet utilizes Amazon's optimized technology plus Wi-Fi networks to enable you to wirelessly search, discover, and download content on the go. Your books and periodicals are delivered over Wi-Fi via Whispernet in less than 60 seconds. Wireless download speeds can vary based on file size. 

New, Built-In Wi-Fi
Kindle automatically detects nearby Wi-Fi networks at school, home, or your favorite café. At a hotel or café that requires a password? Simply enter the password and connect to the network. Once you have added a Wi-Fi network, Kindle will automatically connect to that network the next time you’re near the hotspot. Kindle does not currently connect to enterprise or peer-to-peer networks. 

Free Access at AT&T Hotspots
Enjoy free Wi-Fi access at AT&T hotspots across the U.S. for shopping and downloading Kindle content — no AT&T registration, sign-in, or password required.

 

Holds Over 3,500 Books
The ultimate travel companion, Kindle weighs 8.5 ounces and holds up to 3,500 books. No longer pick and choose which books fit in your carry-on. You can always have your entire Kindle library with you. 

Worry-Free Archive
Delete with abandon. We automatically keep an archival copy of your Kindle books—re-download for free, anytime. We even back up your last page read and annotations, so when you re-download to the device you can pick up where you left off with all of your notes still in place. Please see more information about your library content. 

Collections
Organize your Kindle library into collections, or categories, to easily access any book you are looking for. You can add an item to multiple collections to make organizing and finding titles even easier. For example, you can add the same book to your "History" and "My Favorite Authors" collections. 

Lose Yourself in Your Reading
The most elegant feature of a physical book is that it disappears while you're reading. Immersed in the author's world and ideas, you don't notice a book's glue, the stitching, or ink. Our top design objective is to make Kindle disappear — just like a physical book — so you can get lost in your reading, not the technology. 

Paper-Like Screen with 50% Improved Contrast
Our latest Kindle wireless reading device uses Amazon's all new, high-contrast E Ink screen with 50% better contrast, for the clearest text and sharpest images. With our new display, text "pops" from the page, creating a reading experience most similar to reading on printed paper. Sharp and natural with no glare or backlight, reading on Kindle is nothing like reading on a computer screen. Those who see it for the first time always do a double-take. 

New Proprietary Screen Technology - Faster Page Turns, New and Improved Fonts
Kindle’s new, high-contrast display is further optimized with Amazon’s proprietary waveform and font technology to make pages turn faster and fonts sharper. Waveform is a series of electronic pulses that move black and white electronic ink particles to achieve a final gray level for an image or text. We have tuned Kindle's waveform and controller mechanism to make page turning 20% faster. This waveform tuning, combined with new hand-built, custom fonts and font-hinting, make words and letters more crisp, clear, and natural-looking. Font hints are instructions, written as code, that control points on a font character's line and improve legibility at small font sizes where few pixels are available. Hinting is a mix of aesthetic judgments and complicated technical strategies. We've designed our proprietary font-hinting to optimize specifically for the special characteristics of electronic ink. 

Read in Sunlight with No Glare
Kindle's screen reflects light like ordinary paper and uses no backlighting, eliminating the glare associated with other electronic displays. As a result, Kindle can be read as easily in bright sunlight as in your living room. 

Adjustable Text Size
Kindle has eight adjustable font sizes to suit your reading preference. You can increase the text size of your favorite book or periodical with the push of a button. If your eyes tire, simply increase the font size and continue reading comfortably. Now every book in your library can be large print. 

New Font Choices
Kindle now has three font styles to choose from - our standard Caecilia font, a condensed version of Caecilia, and a sans serif option - so you can change your font style along with the font size. 

Screen Rotation
Manually rotate the display from portrait to landscape to view maps, graphs, tables and Web pages. 

Newspaper Reading
Using Kindle's 5-way controller, you can quickly flip between articles, making it faster and easier to browse and read the morning paper. Want to remember the newspaper or magazine article you just read? Clip and save entire articles for later reading with a single click. Newspapers are auto-delivered wirelessly to Kindle before they hit newsstands. 

Sharp Display of Images and Photos
Kindle's high-resolution screen boasts 16 shades of gray and 50% improved contrast, for the sharpest text and images. 

Support for Non-Latin Characters
Kindle can now display Cyrillic (such as Russian), Japanese, Chinese (Traditional and Simplified), and Korean characters in addition to Latin and Greek scripts for certain file types. To view your personal documents with non-Latin characters on your Kindle, send your file as a Microsoft Word document (DOC) attachment to your Kindle's e-mail address ("name"@free.kindle.com). The file will be converted to Kindle format and sent to your Kindle via the Wi-Fi connection and also to the e-mail address associated with your Amazon.com account at no charge. See more details about Kindle’s Personal Document Service via Whispernet here. Loading TXT files containing non-Latin characters over USB is currently not supported as some characters may not display properly. 

Full Image Zoom
Images and photos display crisply on Kindle and can be zoomed to the full size of the screen. 

Precise 5-Way Controller
Kindle has an easy-to-use 5-way controller, enabling precise on-screen navigation for selecting text to highlight or looking up words. No on-screen fingerprints.
