Supernote Manta: a paper-feel e-ink tablet you can take apart and repair yourself

The A5 X2 Manta ships with a tool-free back panel, swappable battery and upgradable motherboard — repairability built into a writing tablet.

当时的题目

E-ink tablets replaced paper notebooks for writers, but like most consumer electronics they are sealed: when the battery ages, the whole device dies. Supernote set out to prove a writing device could be as repairable as a pen — user-swappable parts instead of a glued-shut shell.

它是怎么成立的

Supernote's A5 X2 Manta, announced in December 2024 for $459, is a 10.7-inch e-ink notebook aimed at people who replaced paper with digital writing. It pairs a 300ppi flexible E Ink screen with a FeelWrite 2 self-healing writing film and a ceramic-tip pen that never needs charging — a device built around the feel of writing, not around apps.

The unusual decision is inside. The back panel removes without tools, exposing a replaceable 3,600mAh battery, an upgradable RK3566 quad-core motherboard, and a microSD slot that takes storage from 32GB up to 2TB. Supernote publishes a teardown guide, and its two-year warranty is described as 'modular design for easy user self-repair' — the manufacturer's pitch is that you fix it yourself instead of shipping it back or buying a new one.

The design also commits to longevity in software: Supernote guarantees at least four years of system updates from launch, with the Manta covered until December 2028. The Verge covered the launch by noting the tablet could be a real alternative to the reMarkable 2 for buyers who want a larger screen and a device that is easy to upgrade and repair.

妙在哪

Tool-free access makes repair a normal user action, not a specialist service.
A replaceable battery and upgradable mainboard decouple the device's life from its battery's lifespan.
microSD expansion and a swappable motherboard let storage and performance grow without buying a new tablet.
Publishing a teardown guide and a dated update guarantee makes the repairability promise auditable, not just marketing.
The writing-first design (paper feel, no frontlight) means repairability reinforces the product's purpose instead of distracting from it.

做出来什么

Launched December 2024 at $459; The Verge and IT之家 both highlighted the tool-free repair design at launch. The company backs it with a two-year warranty framed around user self-repair and guarantees system updates through December 2028.

可以借走的

Plan for the product's death at birth: swappable battery and mainboard let a device outlive its components — repairability as a durable feature, not a repair afterthought.

后来

The Manta launched alongside the smaller A6 X2 Nomad as Supernote's modular flagship line. It was widely reviewed as one of the best-feeling writing tablets of its generation, and the tool-free battery and motherboard swaps became its defining talking point. Supernote continues to document replacement procedures and keeps the Manta on a guaranteed update path through December 2028.
