An E-Reader, or electronic reader, is a portable device designed primarily for reading digital e-books and periodicals. These devices use e-ink technology to provide a paper-like reading experience, reducing eye strain and improving battery life compared to traditional screens. Popular models include the Amazon Kindle and Kobo Clara. E-Readers often come with features such as adjustable font sizes, built-in dictionaries, and the ability to store thousands of books. They have revolutionized the way people consume literature, making it easier to carry an entire library in a compact form. Many E-Readers also offer access to online bookstores and libraries, enhancing the reading experience.
