Readmoo's mooInk V: Folding E-Ink Tablet for Ultimate Reading?

04/18/2025 Technology

The world of e-readers is about to get a whole lot more interesting with the introduction of the Readmoo mooInk V. This innovative device takes the familiar form factor of a book-style foldable phone and applies it to an e-reader, potentially offering a new level of portability and convenience for avid readers.

Readmoo, a Chinese brand, is making waves with its mooInk V, which features an 8-inch folding color E Ink display. The device is designed to be compact enough to slip into a pocket, offering a compelling alternative to traditional paperbacks and standard e-readers like Kindles. The promise of a more colorful display and a unique design adds to its appeal.

E Ink Gallery 3 Technology

The mooInk V utilizes E Ink Gallery 3 technology, also found in the reMarkable Paper Pro. This technology employs color ink capsules (yellow, cyan, and magenta) that are manipulated by an electrical field, resulting in more vibrant colors compared to older E Ink technologies like Kaleido. However, there are potential trade-offs. Gallery 3 is known for its slower refresh rate, which might impact the reading experience, especially when quickly flipping through pages.

Readmoo claims to have used "multiple new materials" and optimized stacking to achieve the folding form factor, despite the typical thickness of E Ink displays. The device boasts a resolution of 300 ppi, ensuring sharp text even on a relatively small screen. However, like all folding devices, the mooInk V may suffer from a visible crease in the center of the display, which could be distracting when light reflects off it.

Durability and Design

The mooInk V features an aluminum-magnesium alloy shell with a silver finish, weighing in at just 255 grams. Durability is a key concern for folding devices. Readmoo claims the device has passed 200,000 bending tests. However, real-world usage often presents unique challenges. The hinge design and its ability to prevent dust intrusion remain to be seen.

While Readmoo has not yet announced a release date or pricing, it's likely that the mooInk V will come with a premium price tag. Folding devices generally cost more than traditional flat-screen devices due to the complex engineering and manufacturing involved.

The appeal of a pocket-sized color E Ink display is undeniable. If Readmoo can deliver on its promises of portability, durability, and a pleasant reading experience, the mooInk V could be a game-changer for book lovers.
