A water-resistant e-reader is protected from water damage. Most water-resistant e-readers have an IPX8 certification. This means that they're waterproof and can even go underwater completely. You can easily use a water-resistant e-reader at the pool, on the beach, or in the bath tub. You can put thousands of e-books on an e-reader. This allows you to bring many books on your vacation, so you'll never be without something to read. Do you often take the e-reader on the go? Choose a compact 6 or 7-inch device. A large e-reader of 9 or 10 inches is ideal for at-home use.
