# Keychain E-Ink Readers Pala One Mini E-Reader by Paul Lagier Compresses into a Pocket-Size Device By Amy Duong | Published 2026-04-16 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/pala-one References: [yankodesign](https://www.yankodesign.com/2026/04/14/worlds-tiniest-e-reader-is-the-size-of-an-airpods-case-and-it-makes-you-read-more/)  Pala One mini e-reader by Paul Lagier is a compact device designed to function as a fully standalone reading tool within a form factor comparable to an AirPods case. The unit is built around an ESP32 microcontroller and a small e-ink display, housed inside a 3D-printed enclosure that clips onto a keychain. Interaction is reduced to a single physical button, creating a simplified interface that cycles through pages and menus without touch input or additional controls. The device stores approximately six to ten books at a time, using compressed text files to maximise limited onboard memory. Updates to the second version include improved casing with screw-fastened assembly, faster loading speeds, and folder-based navigation. The design prioritises constant accessibility, allowing the reader to remain attached to keys or bags so it is always within reach.
