Score: 78/100Rankings

The PocketBook InkPad 4 is a 7.8-inch color e-reader with a vivid Kaleido 3 display and robust waterproof build. Its weight and lack of expandable storage are notable trade-offs. Ideal for readers who prioritize color comics and durability over ultra-light portability.

The Kobo Clara BW is a 6-inch black-and-white e-reader with a high-resolution 300 PPI E Ink Carta 1300 display and IPX8 waterproof rating.
