What makes the Boox Picco stand out?

The Boox Picco is designed for users who want an ultra-portable eReader, featuring a 3.97-inch e-paper touchscreen and physical page-turn buttons that can be customized for other functions. Key features include a microSD card slot for storage expansion, a USB-C port for modern charging and data transfer, and a front light for reading in various lighting conditions.

Unlike Boox’s larger eReaders, the Picco runs a lightweight Linux-based operating system, not Android. This choice aims to streamline performance and potentially extend battery life, but it also places limits on apps and integration with large eBook ecosystems like Kindle or Kobo.

Both the Boox Picco and Xteink X4 Pro offer compact screen sizes and prioritize portability. However, there are notable differences that could shape your decision:

  • Charging and Ports: Boox Picco uses USB-C, which is becoming standard across modern devices. The Xteink X4 Pro relies on a proprietary charging port, which may be less convenient.
  • Magnets: The Xteink X4 Pro can attach magnetically to other devices, such as the back of some phones—a feature missing from the Picco. This might matter if you prefer attaching your eReader for quick access.
  • Operating System: The Boox Picco’s Linux OS does not support Android apps, reducing compatibility with third-party reading apps. The Xteink X4 Pro also requires sideloading and won’t work out-of-the-box with common DRM-protected content.
  • Book Loading Options: Both devices make sideloading necessary for most users, but the Picco offers multiple methods, including microSD, USB-C, cloud upload, and LAN network transfer.

Both eReaders are expected to be priced near $100, making their value directly comparable. However, neither device is suitable for readers who want seamless access to Kindle or Kobo ebook stores.

Who should consider the Boox Picco—and who should skip it?

Buy the Boox Picco if:

  • You prioritize portability in an eReader above everything else.
  • You want flexible book import options (microSD, USB-C, cloud, or network).
  • You dislike proprietary charging ports and prefer USB-C connectivity.
  • You are looking for a distraction-free device and do not need Android app support.

Skip the Boox Picco if:

  • You need built-in access to Kindle, Kobo, or other major reading apps.
  • You want a device that magnetically attaches to your phone or accessories.
  • You read a lot of DRM-protected content that isn’t easily sideloaded.
  • You need features offered by mainstream eReaders (waterproofing, large screen, or ecosystem sync).

If compact size, modern charging, and customizable physical controls matter more to you than app variety or ecosystem integration, the Boox Picco could be a strong fit for a secondary reader or for travel.

The Boox Picco is a highly niche choice, designed for readers who value portability and open formats over deep ecosystem integration. Its USB-C port and storage expansion may appeal to tech-savvy users, while its lack of Android and magnetic features are trade-offs compared to direct rivals like the Xteink X4 Pro. For those satisfied with sideloading and basic reading features, the Picco could deliver strong value if priced competitively. Readers needing seamless content delivery, app support, or integration with large eBook platforms should look at alternatives from Amazon, Kobo, or Boox’s Android-powered models.
