Xteink X4 Overview: The Pocket-Sized E-Reader
The Xteink X4 is a minimalist e-book reader that fits in the palm of your hand. It measures just 114 x 69 x 5.9 mm and weighs a mere 74 grams. That is roughly the size of a credit card. The device uses a 4.3-inch e-ink display with a resolution of 220 ppi.
It does not have a touchscreen. You use physical side buttons to turn pages and access menus. It also lacks a built-in front light. You need ambient light to read.
The X4 runs on an ESP32 microcontroller instead of a traditional processor. It uses a 32GB microSD card for storage (expandable up to 512GB) and has no internal storage. It supports Wi-Fi and Bluetooth for file transfers. The 650 mAh battery delivers around 14 days of use with one to three hours of daily reading.
The stock software reads EPUB and TXT files and displays JPEG, PNG, and BMP images. A magnetic back attachment lets you snap it onto a smartphone case, which is a unique and clever feature.
Pros:
- Ultra-portable at just 74 grams and credit-card size
- Very affordable at $69
- Expandable storage up to 512GB via microSD
- Magnetic attachment system for smartphones
- Active open-source firmware community (CrossPoint)
- Distraction-free reading with no apps or notifications
Cons:

- Limited stock software with few supported formats
- No built-in bookstore or Kindle ecosystem access
- Only supports English, Japanese, and Chinese natively
Kindle (2024) Overview: The Trusted Standard
The Kindle (2024) is Amazon’s entry-level e-reader. It features a 6-inch glare-free display with 300 ppi resolution. The screen is sharp and clear. Text looks crisp at every font size.
It weighs 158 grams (5.6 oz) and measures 157.8 x 108.6 x 8.0 mm. It is the lightest and most compact Kindle Amazon has ever made. The device comes with 16GB of internal storage, enough for thousands of books.
The Kindle has an adjustable front light that lets you read in complete darkness or bright sunlight. It supports dark mode for nighttime reading. The 2024 model is brighter and has faster page turns than its predecessor.
You get full access to the Amazon Kindle Store with millions of titles. Whispersync keeps your reading position, bookmarks, and highlights synced across all your Kindle devices and apps. It also supports Kindle Unlimited and Prime Reading.
Pros:
- Sharp 300 ppi display for clear, comfortable reading
- Adjustable front light with dark mode
- Full Amazon Kindle Store integration
- Whispersync across devices and apps
- 16GB internal storage for thousands of books
- Up to 6 weeks of battery life
- USB-C charging
Cons:
- Higher starting price at $109.99

- Does not natively support EPUB format
- Locked into the Amazon ecosystem
- No expandable storage
- Larger and heavier than the Xteink X4
Display Quality Comparison
The display is the heart of any e-reader. The Kindle wins this category clearly. Its 6-inch, 300 ppi screen produces crisp, paper-like text. Every letter is sharp. You can read for hours without eye strain.
The Xteink X4 has a 4.3-inch, 220 ppi display. Text is readable but noticeably less sharp than the Kindle. The smaller screen also means you see fewer words per page. You will tap the page-turn button more often.
The biggest difference is the front light. The Kindle has an adjustable built-in light that lets you read anywhere. The Xteink X4 has no front light at all. You cannot read the X4 in a dark room without an external light source. If you read before bed, this is a dealbreaker.
Portability and Design
This is where the Xteink X4 dominates. At just 74 grams and 5.9 mm thin, it disappears into a pocket. It is smaller than most smartphones. The magnetic back lets you attach it to your phone case, so you can carry it without even thinking about it.
The Kindle (2024) is still portable at 158 grams. It fits comfortably in a bag or large pocket. But you cannot slip it into a shirt pocket or attach it to your phone.
The Xteink X4 is built for people who want to read everywhere without carrying a separate device. If you commute by train, stand in lines, or travel light, the X4’s size is a huge advantage. The Kindle, though compact for a 6-inch device, is a traditional e-reader form factor.
Reading Experience and Software
The Kindle offers a far superior reading experience out of the box. Amazon’s reading software is polished and feature-rich. You get adjustable font sizes, multiple font styles, line spacing controls, margin settings, and a built-in dictionary. X-Ray lets you explore characters and themes. Word Wise helps language learners.
The Xteink X4’s stock software is basic. It reads EPUB and TXT files. Font options are limited to small and medium sizes. There is no dictionary, no highlights, and no bookmarks in the stock firmware.
However, the CrossPoint custom firmware changes the story. It adds better typography, more font sizes, improved layouts, and wireless book transfers. If you are willing to install CrossPoint, the reading experience improves significantly. But it still does not match the Kindle’s polish.
Book Ecosystem and File Support
The Kindle gives you instant access to Amazon’s massive library. You can buy and download books in seconds. Kindle Unlimited offers unlimited reading for a monthly fee. Prime members get free access to thousands of titles through Prime Reading.
The Xteink X4 has no built-in bookstore. You must sideload books manually. The stock software supports EPUB and TXT only. The CrossPoint firmware adds a few more formats. You can transfer files via Wi-Fi, Bluetooth, or USB-C.
If you already own a large EPUB library, the X4 works well. If you prefer to browse, buy, and read books from one place, the Kindle is the obvious choice. The Kindle does not support EPUB natively, but you can convert files using free tools like Calibre or send EPUBs via Amazon’s Send to Kindle feature.
Battery Life
Both devices offer solid battery performance. The Kindle (2024) lasts up to 6 weeks on a single charge. Amazon bases this estimate on 30 minutes of daily reading with the front light at setting 13 and Wi-Fi off.
The Xteink X4 lasts about 14 days with one to three hours of daily reading. Its 650 mAh battery is smaller, but the device also uses less power because it has no front light and runs on an efficient ESP32 chip.
Both devices charge via USB-C. The Kindle takes about 2.5 hours for a full charge. The X4 charges faster due to its smaller battery. For most readers, either device will last long enough between charges. But the Kindle clearly wins on total battery life.
Storage Options
The Kindle (2024) comes with 16GB of internal storage. This is enough for thousands of e-books. You cannot expand it with a memory card. Cloud storage through Amazon lets you archive books and re-download them anytime.
The Xteink X4 has no internal storage. It relies entirely on a 32GB microSD card included in the box. You can upgrade to cards up to 512GB. This gives you far more local storage than any Kindle model.
If you carry a large offline library with many files, the X4’s expandable storage is a strong advantage. If you prefer cloud-based management and automatic backups, the Kindle’s integration with Amazon’s cloud is more convenient.
Price and Value
The Xteink X4 costs $69. That is one of the lowest prices for any current-generation e-ink reader. You get a functional, ultra-portable reading device for less than most budget smartphones.
The Kindle (2024) starts at $109.99 for the ad-supported version. The ad-free version costs $129.99. The Kindle Paperwhite starts at $149.99 if you want a larger screen and more features.
The Kindle Paperwhite (2024) offers a 7-inch display, 300 ppi, faster page turns, and an adjustable warm light. It is worth considering if budget allows.
In terms of raw value, the X4 is hard to beat at $69. But the Kindle delivers a complete reading ecosystem that justifies its higher price for most readers.
Who Should Buy the Xteink X4?
The Xteink X4 is perfect for a specific type of reader. If you want extreme portability above everything else, this is your device. It fits in any pocket. It weighs almost nothing.
It is also great for tech enthusiasts who enjoy tinkering with custom firmware. The CrossPoint community is active and growing. You can customize the device to match your preferences.
Budget-conscious readers will love the $69 price. If you already have a large EPUB library and just want a simple, distraction-free way to read, the X4 delivers. It is also a solid secondary e-reader to complement a larger device at home.
Who Should Buy the Kindle?
The Kindle is the right choice for most readers. It offers a polished, complete reading experience right out of the box. You do not need to sideload files or install custom firmware.
If you read before bed, the Kindle’s adjustable front light is essential. If you want to buy books instantly, the Kindle Store has no equal. If you use multiple devices, Whispersync keeps everything in sync.
The Kindle is also better for casual readers who want simplicity. Turn it on, pick a book, and start reading. No setup required. No microSD cards to manage. Amazon handles everything.
