SMARTER READING, LESS DISTRACTION
Meet Metalio E-Ink4: A Pocket-Sized AI E-Reader
Looking for a lightweight reading companion with smart features? Discover the Metalio E-Ink4 and E-Ink4 Plus, two compact E Ink readers designed for reading, learning, and everyday carry.
Compact design, physical buttons, and an E Ink screen.
A Tiny E-Reader That Goes Everywhere
Sometimes, all you want is a book without the distractions of a smartphone. Whether you're commuting, waiting for a flight, or enjoying a quiet coffee break, a compact E Ink reader makes it easy to keep reading throughout the day.
The standard Metalio E-Ink4 features a 3.97-inch E Ink touchscreen with an 800 × 480 resolution and 235 PPI. Weighing approximately 70 g and measuring just 6.8 mm thick, it's designed to slip easily into your pocket or bag.
The standard version has no front light, so you'll need sufficient ambient light when reading. Its reflective E Ink display offers a paper-like viewing experience without the bright, self-illuminated look of a typical phone screen.
More Than Reading: Explore AI Features
The Metalio E-Ink4 combines ebook reading with voice-based AI features, bringing selected smart tools into a compact device.
Depending on software configuration and service availability, supported features include AI-powered question answering, general knowledge inquiries, translation, and AI image generation. Instead of constantly switching between apps on your phone, you can explore these capabilities on a dedicated device.
It's an interesting option for curious readers, language learners, and tech enthusiasts who want to experiment with AI while keeping a small reading companion close at hand.
AI services may require Wi-Fi access and compatible service configuration. Specific features and availability can vary with the software version.
A compact screen for everyday information and personalization.
Physical Buttons Meet Touchscreen Control
Prefer tactile controls, or do you like tapping directly on a screen? The Metalio E-Ink4 combines physical buttons with touchscreen interaction, giving you flexible ways to navigate and use supported functions.
With speaker and microphone support, the device also offers audiobook playback and voice interaction. It's designed for readers who want more than a basic ebook display in a small, portable format.
Meet the Metalio E-Ink4 Plus: A Bigger Screen
Want more screen space? The Metalio E-Ink4 Plus offers a larger 4.7-inch E Ink display with a 684 × 1216 resolution and 297 PPI. Its 2000 mAh battery also provides a larger capacity than the standard version's 1000 mAh battery.
The Plus is available in different configurations, including versions with and without a front light. If you often read in dim environments, choose the front-light version and adjust its brightness to suit your surroundings.
Despite its larger screen, the Plus remains compact, measuring approximately 122 × 71 × 7.8 mm and weighing around 100 g.
A portable reading companion for commutes, trips, and everyday downtime.
