The Field Guide
A compact e-reader is a phone-sized — or smaller — E Ink reader you carry everywhere, not a full-size Kindle you leave at home. This is the map: what the category is, who it's for, and how the pocketable Xteink X4 and X3 compare to the Boox Palma, Kindle and Kobo.
New here? Start with X3 vs X4, then the $69-vs-$250 Boox Palma comparison.
Screens roughly 3.7"–6", light enough to live in a jacket or front pocket. The point is that it goes where a phone goes.
From single-purpose button readers (Xteink) to E Ink Android devices (Boox Palma). All trade screen size for focus and carry.
Most shine with DRM-free EPUB/TXT and side-loaded books; some run full reading apps. Know which before you buy.
The smallest one — pogo-pin charging, phone-back carry.
The most pocketable Xteink. A 3.7-inch, 259-PPI E Ink reader that rides on the back of your phone via magnets. Charges over a proprietary magnetic pogo-pin cable rather than USB-C, which is its one real quirk.
The mainstream pick — bigger screen, plain USB-C.
The 4.3-inch model most people buy. ESP32-powered, USB-C charging, magnetic-ready, and the centre of the community firmware and modding scene. No front light and no touchscreen — that is the design, not an omission.
A front-lit Android model, the Xteink S4, is expected internationally around July 2026 — see how it compares to the X4.
The pocket-E-Ink field runs from $69 button readers to $250+ Android devices. Here's where the Xteink sits against the names you're probably also weighing.
