What we like about Onyx Boox Tab X

  • Massive 13.3-inch A4-sized screen is ideal for full-scale PDF reading and annotation without zooming
  • Dedicated GPU and 'Super Refresh' technology provide exceptionally smooth performance and fast refresh rates for an e-ink device
  • Open Android 11 system with full Google Play Store access allows for high flexibility with third-party apps
  • Excellent build quality with a premium magnesium-alloy back and a durable, flexible Mobius plastic screen
  • Large 6,300mAh battery provides significant longevity, often lasting weeks on a single charge for standard reading tasks
  • Split-screen mode takes full advantage of the large display for multitasking between documents and notes

What we don't like about Onyx Boox Tab X

  • Extremely high price point (approx. $880/£880) makes it a niche luxury compared to standard tablets like the iPad
  • The 13.3-inch footprint is bulky and can be unwieldy or heavy for casual handheld reading in bed or on a couch
  • Lacks a fingerprint sensor and a dedicated SD card slot for storage expansion
  • No integrated magnetic attachment or silo for the stylus, making the pen easy to misplace without a specialized case
  • Screen resolution (207 PPI) is lower than 10-inch competitors (300 PPI), which can lead to slightly less sharp text
  • Ghosting (lingering images from previous pages) remains a prevalent issue during drawing and high-speed scrolling

Verdict

The Onyx Boox Tab X is a flagship 13.3-inch E-Ink tablet featuring an A4-sized Mobius Carta 1250 display with a 2200 x 1650 resolution (207 PPI) and a dedicated GPU for enhanced refresh rates. It is powered by a Qualcomm octa-core processor, 6GB of LPDDR4X RAM, and 128GB of internal storage, all running on Android 11 with full Google Play Store access. Key pros include its expansive screen area ideal for full-size PDF viewing, low-latency handwriting with the included Pen 2 Pro stylus, and a massive 6,300mAh battery for extended use. However, notable cons include its high price point, the lack of expandable storage, and a bulky 560g frame that can be cumbersome for long reading sessions compared to smaller devices.
