InkBook Focus

InkBook Focus

7.8 inches with 300 ppi, Android app support, page-turn buttons, and blue light reduction – what more could you want?

The InkBook Focus positions itself as a solid 7.8-inch Android eReader featuring an E-Ink Carta display, sharp 300 ppi pixel density, and built-in front light with night mode. With two page-turn buttons on each side of the screen, the device offers comfortable usability for both left- and right-handed users. Weighing in at around 251 grams, it falls within the mid-range for its size class and shouldn’t pose any issues during longer reading sessions. Thanks to Bluetooth support, the eBook reader can also be used for listening to audiobooks and music. At around 230 euros, the price-performance ratio is fair.

InkBook Focus: At a Glance

The InkBook Focus is an e-reader that tends to fly under the radar. That’s not because it’s a bad device, but rather because the company behind it is relatively unknown. In fact, the Polish company has been bringing Android e-readers to market for many years.

InkBook used to be known as Arta Tech and brought Onxy Boox readers to Europe as a reseller. In 2015 the two companies parted ways, stating that they wanted to improve the quality of the products they sold. InkBook was initially just the name of its own e-reader brand, but later became the company name as well.

InkBook’s premium model

The Focus is InkBook’s third premium or high-end model, following the Prime HD and Explore released in 2018.

Like the InkBook Explore, the display measures 7.8 inches diagonally and still offers 300 ppi (1872×1404 pixels). As is customary in this segment, it uses E-Ink Carta.

The screen can be illuminated by built-in LEDs, and a night light with reduced blue light is also available.

Android as a selling point

InkBook knows its audience and clearly positions the InkBook Focus with the promise that a wide range of e-reading services can be used on the device. The official product page specifically mentions Kindle, Kobo, Onleihe, Skoobe, and several other services.

This is made possible by using Android as the operating system. In version 8.1, it lets you use many current apps. Alongside the display size, the Android version is also the second major update compared to the previous model generation. The InkBook Prime HD and Explore were still running Android 4.2.2, where app support has been eroding for quite some time.

Solid hardware

Beyond those points, the InkBook Focus also offers solid hardware: 16 GB of internal storage should be sufficient for most use cases, and the 2,900 mAh battery likewise provides enough capacity so that battery life doesn’t suffer despite Android.

The device is powered by a quad-core processor paired with 1 GB of RAM. That’s a significant leap from its predecessor, which had to make do with a single-core CPU. As a result, most apps should run smoothly and are more likely to be limited by the inherently modest response time of the E-Ink display.

Wi-Fi and Bluetooth are available for wireless connectivity. The latter lets you use the e-reader to listen to music and audiobooks – provided you have compatible headphones or speakers.

Two page-turn buttons on each side of the display round out the solid feature set. That makes the e-reader comfortable to use for both left- and right-handed users.
