Color Display vs Monochrome Screen
display type
The PocketBook InkPad Color 3 features an enhanced E Ink color display, making it suitable for comics, magazines, and color-rich ebooks. This allows you to view vibrant images without losing the eye-friendly reading experience. The PocketBook InkPad 4 uses the E-Ink Carta 1200 screen, which is a high-quality monochrome e-paper panel. It provides a crisp, glare-free experience that closely mimics paper, ideal for long reading sessions of standard text. If you primarily read novels, the monochrome screen offers excellent contrast. If you need color graphics, the Color 3 is the better choice for your visual needs.
storage capacity
Storage is a key differentiator between these two devices. The PocketBook InkPad Color 3 comes with 32GB of internal storage, allowing you to save thousands of ebooks, audiobooks, and documents. It also supports expansion via external memory cards, giving you even more flexibility for large libraries.

While it supports 25 popular formats without conversion, you should check the manufacturer details for its exact storage limits. For users with extensive collections of media files, the Color 3 offers a clear advantage with its generous 32GB capacity.
battery life
Battery endurance is important for portable reading. The PocketBook InkPad Color 3 is rated for up to one month of battery life on a single charge, which is ideal for travel or outdoor reading without frequent charging. The PocketBook InkPad 4 data does not explicitly state its battery duration. Both devices are designed for long reading sessions, but the Color 3 provides a verified metric for power efficiency. If you often go days without access to a power outlet, the stated one-month lifespan of the Color 3 gives you more confidence in its reliability compared to the unspecified duration of the InkPad 4.
weight and build
Physical handling affects comfort during long sessions. The PocketBook InkPad 4 weighs 1.01 pounds, which is approximately 16.16 ounces. The PocketBook InkPad Color 3 weighs 15.9 ounces.

The InkPad 4 is 8.46 inches tall, while the Color 3 is 8.43 inches tall. The Color 3 is marginally more compact and lighter, which may be preferable for one-handed reading.
connectivity and apps

The PocketBook InkPad 4 includes SMARTlight with adjustable color temperature for eye-safe reading in any lighting. The PocketBook InkPad Color 3 also features SMARTlight and adds dual-band wireless connectivity for seamless syncing.
