Considerations & Limitations

• Contrast / Display Standard: Some users report that the screen contrast or “black level” is not as deep as in some competing models; letters may look a bit washed‑out under certain lighting or font settings. :contentReference[oaicite:18]{index=18}
• Performance: With 1 GB RAM and dual‑core CPU, performance is adequate but not ultra‑fast, especially for large PDF files or heavy multitasking. :contentReference[oaicite:19]{index=19}
• No SD card slot: Storage is not user‑expandable via microSD (external memory is possible via OTG but not internal). :contentReference[oaicite:20]{index=20}
• Weight & Size: At ~265 g and fairly large dimensions, it’s less compact than smaller 6‑inch or 7‑inch e‑readers. :contentReference[oaicite:21]{index=21}
• Battery Life Varies: Though rated for long usage, heavy use of front light, Bluetooth/audio, and frequent page turns or apps will reduce actual battery life. :contentReference[oaicite:22]{index=22}

Conclusion

The PocketBook 743G InkPad 4 is a strong mid‑high level e‑reader for those who want more screen, good resolution, audio capabilities, durable build (IPX8 water resistance), and wide format support. It’s especially good if you often read large texts, PDFs, or want audio/text‑to‑speech. If your usage is lighter—just small EPUB novels, only text, and you value portability—some smaller, lighter models may suit you better. But for what it offers, it gives excellent value in its class.
