An E-reader is a portable electronic device designed specifically for reading digital books, magazines, and other written content. Unlike tablets or smartphones, E-readers use a special screen technology called E Ink, which mimics the appearance of printed paper. This makes reading on an E-reader comfortable, even in bright sunlight, and helps reduce eye strain. Many E-readers come with features like adjustable font sizes, built-in dictionaries, and the ability to store thousands of books. Popular models include the Amazon Kindle and Kobo Clara. With an E-reader, you can carry an entire library in your bag, making it easy to read anywhere you go.
