The latest e-reader to hit the shelves in 2025 is the iReader Ocean 4 Long-Life Edition—a stylish and smart device that takes clear inspiration from the Kindle Oasis. It brings top-tier features to readers who want performance, comfort, and sleek design all in one.
At just 4mm thick at its slimmest point and weighing only 179 grams, the Ocean 4 is incredibly light and easy to hold, perfect for one-handed reading, whether you’re lounging at home or on the go. Its 7-inch E Ink Carta 1300 display delivers crisp, black-and-white visuals with a resolution of 1680 x 1264. The screen is glare-free, making it easy on the eyes, even in bright sunlight.
What sets this display apart is the i-Clean technology, which instantly refreshes the screen to remove ghosting from previous pages. Combined with the ComfortLight Pro+ system, the Ocean 4 offers a smooth and evenly lit display. With 30 levels of brightness and color warmth to choose from, users can adjust the screen to suit any environment. In fact, the screen is now 18% brighter than earlier models, making reading even more enjoyable.
Inside, the iReader Ocean 4 runs on a processor specially designed for E Ink performance. It includes 1 GB of memory and a generous 64 GB of storage—plenty of space for thousands of books. A powerful 2000 mAh battery keeps the device running for up to 96 hours on a single charge.
Connectivity is also strong, with support for dual-band Wi-Fi (2.4/5.0 GHz) and Bluetooth 5.0. There’s a USB-C port for fast charging and data transfer, as well as built-in speakers, a microphone, and a gravity sensor for automatic screen rotation. Whether you’re a student, a casual reader, or a tech enthusiast, this newest Kindle Oasis-style e-reader is designed to deliver a smooth, comfortable reading experience every time you open a book.
Available in stylish interstellar black and arctic white, the iReader Ocean 4 is priced at 1,399 yuan (around $192 USD).
