    Verdict

    The PocketBook InkPad 4 is a versatile 7.8-inch e-reader featuring a sharp E Ink Carta 1200 touchscreen with 300 PPI resolution and an adaptive SMARTlight for adjustable brightness and colour temperature. Its main characteristics include 32GB of internal storage, IPX8 waterproofing for protection against immersion, and a built-in speaker with Bluetooth connectivity for audiobooks and text-to-speech functionality. Key pros are its extensive support for 25 book formats without conversion, physical page-turn buttons for ergonomic one-handed use, and a long-lasting 2,000 mAh battery. However, notable cons include the lack of a microSD card slot for expandable storage and occasional UI sluggishness compared to more powerful Android-based devices.
