Tiny Magnetic E-Reader Review: Why the Xteink X4 Magnetic E-Reader Is Changing How People Read

The Xteink X4 magnetic e-reader offers a fresh idea that blends reading, mobility, and convenience into one compact tool. Many readers look for a simple and distraction-free way to enjoy books, especially during busy days filled with phone notifications. The Xteink X4 magnetic e-reader approaches this problem with a design that combines a small body, a magnetic attachment system, and an E Ink screen that reduces eye strain.

In this detailed analysis, SquaredTech explains how the device works, why its magnetic feature sets it apart from regular e-readers, what strengths it brings to everyday reading, and where its limitations may influence long-term use. The goal is to give readers clear, practical insight into how this device fits real reading habits.

The Xteink X4 magnetic e-reader is designed for readers who want instant access to text without opening a reading app or carrying a separate device. It prioritizes speed, portability, and focus over ecosystem features.

How the Xteink X4 Magnetic E-Reader Works and Why It Matters

The Xteink X4 introduces a simple idea. It attaches to the back of a smartphone using a magnetic system similar to modern wireless power banks. The device works with phones that support Apple’s MagSafe or the Qi2 magnetic standard, including iPhones and newer models like the Pixel 10. For phones without built-in magnetic support, Xteink includes adhesive magnetic rings to enable the same attachment.

This approach matters because many readers want to read without opening a separate device or carrying a larger e-reader. With the X4, a person can scroll on their phone, flip it over, and switch into reading mode instantly. This small interaction helps reduce distractions and turns the phone into a gateway rather than a barrier to reading.

A Compact Form Factor Built Around Simplicity

The Xteink X4 uses a 4.3-inch E Ink display, making it smaller than the smallest Kindle or Kobo models. Its compact size makes it pocket-friendly and easy to hold with one hand, especially for reading while commuting or waiting.

The E Ink screen reduces visual strain compared to a phone display and feels closer to printed text. However, the screen resolution is 220ppi, while most modern e-readers offer 300ppi. Text appears slightly softer, which some readers may notice. For basic reading and documents, this difference is unlikely to be a dealbreaker.

The device does not include a built-in front light. Users must rely on ambient light or a lamp. While this limits nighttime reading, it significantly reduces power consumption and contributes to the device’s long battery life.

Battery Performance Made for Long Sessions

The Xteink X4 includes a 650mAh battery. While this capacity may seem small, E Ink displays use very little power. Xteink claims the device can last up to 14 days with one to three hours of daily reading. In real-world use, this means most readers will charge the device infrequently.

The absence of a built-in light plays a major role in this efficiency. Without power-hungry LEDs, the battery lasts far longer than most portable reading devices.

These trade-offs become clearer when the device’s strengths and weaknesses are viewed side by side.

This device suits readers who value portability, physical buttons, and manual control over their book files. Readers who want an all-in-one bookstore, built-in lighting for night reading, or high-resolution text may find the Xteink X4 limiting.

Understanding the Software, File Support, and Limitations of the Xteink X4 Magnetic E-Reader

The Xteink X4 focuses on a basic reading experience. This simplicity brings clarity and efficiency, but it also introduces limits that buyers should understand.

Limited Access to Book Stores and Why It Affects the Reading Experience

Major e-readers like Kindle and Kobo offer built-in access to large digital bookstores. The X4 does not. It does not run Android with Google Play support, which means users cannot install major reading apps or download books directly from large platforms.

Instead, the device supports DRM-free EPUB and TXT files. Readers must source books from public-domain libraries, independent publishers, or other legal, DRM-free sources. While this offers flexibility and ownership, it may frustrate readers who rely on Amazon or Kobo ecosystems.

How Users Load Books onto the X4

To load books onto the Xteink X4 magnetic e-reader, the user must sideload files. There are two ways to do this:

1. Using a microSD Card

The device includes a microSD slot. It supports cards up to 512GB. This is a large capacity for simple text files, so it effectively allows a person to carry a lifetime’s worth of books. The user can place EPUB or TXT files on the card through a computer, insert the card, and begin reading immediately.

2. Transferring Books Over Wi-Fi

The X4 supports direct Wi-Fi file transfer. The user can connect the phone or computer to the device over Wi-Fi and then send files wirelessly. This makes the process faster and avoids the need for physical cards or cables.

These two approaches make sideloading simple, but they still require more steps than store-based downloads. The experience suits readers who enjoy manual file management and control over their libraries.

No Touchscreen, but Dedicated Buttons Improve Control

The Xteink X4 does not use a touchscreen. Instead, it relies on physical page-turn buttons. Many readers prefer buttons because they provide tactile feedback and reduce accidental inputs. They also allow reading with gloves, which can be useful while traveling or outdoors.

The device includes two preinstalled fonts, and users can install additional fonts if desired. While formatting options are limited, this level of control suits the device’s minimalist design.

The Kindle Basic focuses on ecosystem access, screen clarity, and long-form comfort. The Xteink X4 takes a different approach by emphasizing access speed, minimalism, and physical interaction. Each device serves a distinct reading habit rather than competing directly.

Why the Xteink X4 Magnetic E-Reader Might Appeal to Readers Today

The Xteink X4 represents a new direction in portable reading. Instead of competing with mainstream e-readers on features, it focuses on portability, simplicity, and a magnetic attachment concept that integrates reading into daily phone use.

Its compact size, long battery life, physical buttons, and distraction-free design appeal to readers who want reading to fit naturally into short breaks and everyday moments.

At the same time, its limits are clear. The lack of a built-in light affects nighttime reading. The absence of bookstore access adds friction for some users. The lower pixel density may matter to readers who value sharp text.

These factors show that the Xteink X4 fits a specific type of reader—one who values focus, simplicity, and portability over features and ecosystems.

The Xteink X4 is not widely available through major retailers like Amazon in most regions. Availability varies by market, and buyers may need to purchase directly from the manufacturer or limited online sellers. Pricing depends on region and supply.

Conclusion: SquaredTech’s Final Take on the Xteink X4 Magnetic E-Reader

The Xteink X4 magnetic e-reader brings a creative idea to the reading market. It attaches to a phone, works with simple file formats, and supports consistent reading with very low power use. Its strengths lie in portability, battery life, and physical controls, while its limits come from screen resolution, lighting, and bookstore access.

As SquaredTech, we believe this device fills a new space in the reading landscape. It shows how smaller, focused tools can influence reading habits and create alternative ways to enjoy books. We will continue tracking this category as more companies explore similar approaches.
