PocketBook vs XTEINK Specs
Screen size
The PocketBook Era Color features a 7-inch E Ink Kaleido 3 display, offering ample space for ebooks, comics, and magazines with sharp text and vivid colors. In contrast, the XTEINK X3 has a much smaller 3.7-inch screen. This compact size makes the XTEINK extremely portable, slipping easily into pockets for reading during commutes or quick breaks. The PocketBook provides a traditional reading experience closer to physical books, while the XTEINK prioritizes minimalism and one-handed portability over page real estate.
Display type
Both devices utilize E Ink technology for an eye-friendly, paper-like reading experience without glare. The PocketBook Era Color specifically uses the newer Kaleido 3 panel, which delivers sharp black-and-white text alongside vivid colors. This allows you to enjoy color comics and magazines effectively. The XTEINK X3 uses a standard E Ink display with a high-aluminosilicate glass substrate for clarity. While it offers a clean, focus-oriented reading environment, it lacks the color capabilities of the PocketBook. If you read mostly text, both work well; for color content, the PocketBook is superior.
Storage capacity
Storage options differ significantly between the two models. The PocketBook Era Color comes with 32GB of internal memory, providing ample space for thousands of ebooks and audiobooks. The XTEINK X3 offers 16GB of built-in storage, which is sufficient for many books but less than the PocketBook. However, the XTEINK supports expandable memory up to 256GB via a microSD card, allowing you to significantly increase your library size. The PocketBook does not mention expandable storage in its specifications. For fixed storage, the PocketBook wins; for potential expansion, the XTEINK has an advantage.
Audio features
Audio functionality is a major differentiator. The PocketBook Era Color includes built-in speakers and Bluetooth connectivity, allowing you to listen to audiobooks directly without headphones. It also supports Text-to-Speech, transforming any ebook into spoken word. The XTEINK X3 does not list speakers or Bluetooth capabilities in its data. It is designed primarily for visual reading, with features like gyroscope page-turn and physical buttons. If you want to listen to books or use TTS, the PocketBook is the clear choice. The XTEINK focuses solely on the visual reading experience.
Build and weight
The XTEINK X3 is designed for extreme portability, weighing only approximately 58g and measuring 5.1mm thin. It features a premium glass construction and a magnetic-ready design with pogo-pin charging. The PocketBook Era Color is larger and heavier, with dimensions of 7.05 by 6.34 inches and a thickness of 1.22 inches. However, the PocketBook offers IPX8 waterproof protection, making it safe from splashes and rain. The XTEINK does not mention water resistance. The XTEINK wins on weight and pocketability, while the PocketBook wins on durability and water protection.
Connectivity
Connectivity options vary by use case. The PocketBook Era Color supports WiFi, USB-C, PocketBook Cloud, Dropbox, and Send-to-PocketBook services, making syncing and transferring content simple across various platforms. It also includes Bluetooth for audio. The XTEINK X3 data does not explicitly list WiFi or Bluetooth capabilities, focusing instead on its magnetic charging and physical controls. It notes that it does not support third-party apps or DRM-protected books from Kindle or Libby. The PocketBook offers more robust wireless connectivity and cloud integration for managing your library.

The PocketBook Era Color features a 7-inch E Ink Kaleido 3 display that delivers vivid colors alongside sharp black-and-white text.

Listeners who enjoy audiobooks and text-to-speech

The XTEINK X3 lacks these audio features, making the PocketBook the superior choice for those who want to listen to their books.
Readers needing waterproof protection for bath or pool
The PocketBook Era Color carries an IPX8 waterproof rating, protecting it from splashes, rain, and submersion. This durability allows you to read safely in the bath or by the pool. The XTEINK X3 does not list water resistance specifications, so the PocketBook is the safer option for wet environments.
