Book lovers who value ultimate portability might want to check out the Xteink X4 Pro, an ultra-tiny e-reader roughly the size of a credit card. The author notes having read 25 books over the past year using this pocket-sized form factor, proving that once you get immersed in reading, screen size stops being an issue while the convenience of slipping it into any pocket shines.

Right now, the X4 Pro—the newest and most advanced e-reader from Chinese tech startup Xteink—is being discounted by 15% on Amazon ahead of next week's October Prime Day event, also known as Prime Big Deal Days. This discount brings the price down to $85, making it an affordable option for mobile readers.

While sharing the exact same compact dimensions as the original X4 pocket e-reader launched last year, the Pro version introduces two major hardware upgrades: a temperature-adjustable front light and a touchscreen. It also packs a faster processor and more memory, pushing the retail cost slightly higher while remaining exceptionally budget-friendly.

Compact e-readers like this offer a distraction-free alternative to smartphones with soothing E-ink displays. However, prospective buyers should note that these miniature devices cannot load existing Kindle library books directly, requiring users to source DRM-free e-book files instead.

These minuscule e-readers certainly aren't for everyone due to screen size limitations and file compatibility hurdles. Even so, for those willing to adapt, the Xteink X4 Pro stands out as one of the most unique and lovable pieces of technology available on the market today.
