The PocketBook InkPad 4 is a versatile e-reader designed for those who prefer a larger screen for a more immersive reading experience. Its 7.8-inch E Ink Carta 1200 display offers a sharp 300 PPI resolution with 16 levels of gray, mimicking the look of real paper. To make reading comfortable in any lighting, the SMARTlight system allows you to adjust both the brightness and the color temperature of the front light. This device is built for durability and convenience, featuring an IPX8 water-resistance rating that lets it be submerged in fresh water up to 2 meters for an hour, making it a safe companion for the bath or the pool. The screen also has improved scratch resistance to handle daily wear. Inside, a dual-core processor and 1 GB of RAM keep the interface smooth, while 32 GB of internal storage provides ample space for a vast library. Connectivity is handled via Wi-Fi and Bluetooth 4.0, and the USB Type-C port ensures modern charging and data transfer. You can enjoy a wide array of formats, from EPUB and PDF to CBR and DJVU, and even listen to audiobooks through the integrated mono speaker or a 3.5 mm adapter. Weighing only 265 g and measuring 7.9 mm in thickness, it remains light enough to hold comfortably for long periods.
