    Verdict

    The Onyx Boox Max Lumi 2 is a professional-grade 13.3-inch E Ink device featuring a high-resolution Mobius Carta 1250 display (2200 x 1650, 207 PPI) specifically designed for A4-sized documents and intensive note-taking. It is powered by a Qualcomm Snapdragon 662 octa-core processor, 6GB of LPDDR4X RAM, and 128GB of internal storage, all running on Android 11 with full Google Play Store support. Its main pros include an expansive screen that eliminates the need for zooming in PDFs, a responsive Wacom-compatible stylus with 4,096 levels of pressure sensitivity, and a robust 4,300mAh battery that provides weeks of standby time. However, notable cons include its high retail price, the lack of an SD card slot for expandable storage, and a writing surface that some users find slightly more slippery compared to smaller, more textured E Ink tablets.
