Expert Review Summary
The Onyx Boox Note Max is a 13.3-inch Android e-note released in January 2025 that achieves 300 PPI resolution across its full A4-sized E Ink Carta 1300 surface, a first for 13.3-inch e-readers. At 4.6mm thin and 615g, it delivers a paper-like writing experience for professionals who replace physical notebooks with a digital device without sacrificing clarity or scale.
A Qualcomm 2.8GHz octa-core processor, 6GB RAM, and 128GB internal storage drive Android 13 with full Google Play access, enabling WPS Office, Google Drive, and third-party productivity apps alongside the native Boox Notes application. The included Boox Pen 2 Plus stylus supports precise handwriting, diagram sketching, and PDF annotation directly on the 3200 x 2400 display. Dual stereo speakers, a microphone, Bluetooth 5.0, and dual-band Wi-Fi complete the connectivity profile, while a USB-C port with OTG support allows connection to external drives.
The notable trade-off is the absence of a front light, meaning the Note Max requires adequate ambient lighting for comfortable use. At $649, it targets professional note-takers, lawyers, architects, and academics who need A4-scale document review and freehand annotation with the sharpest available E Ink rendering. An optional keyboard case expands its use as a portable productivity workstation.
