    ONYX BOOX Tab Ultra C is the first E Reader amongst E Ink color devices with a large color E Ink Kaleido 3 screen of 10.3” with front light and dual touch control. The model has a high-performance hardware platform built on an 8-core Qualcomm processor and 4 GB of RAM and additional features for working with text. Its new graphics processor with BOOX Super Refresh technology provides high-speed screen refresh and smooth movement of objects on the screen. The built-in 16 MP camera in combination with special software allows you to scan and recognize text information. The model runs Android 11 OS and allows you to install and use third-party applications. The built-in Wi-Fi module makes it possible to use network services, and Bluetooth support allows you to connect external devices. Tab Ultra C has a thin body and its screen is covered with protective ONYX Glass. The battery of 6300 mAh higher capacity provides a long battery life. Thanks to the large screen, the ability to display colors and the ability to make handwritten notes, the model will be an excellent choice for those who plan to combine reading books and working with documents with color images. Tab Ultra C supports operation with a genuine magnetic keyboard case, which can be additionally purchased and used to protect the reader during transportation and storage.

    Every Pixel Counts for Comfort

    High definition for both black-and-white and color content makes it easy and fun to read every word. The 50% thinner touch layer makes each bit of electronic ink appears more like a color print on newspaper, creating a pleasant and peaceful view. And the anti-glare color ePaper screen allows you to work even in direct sunlight.

    Pastel Colors Balance Focus and Joy

    The new Kaleido 3 screen's soothing and soft tones bring out the pleasure while maintaining a sense of calm to help you stay focused. Working on the Tab Ultra C will make you feel delighted, serene, and comfortable.

    Ink Kaleido 3 screens display 4096 colors color mode and 16 shades of gray in black and white mode. Optimization of the screen structure allowed to increase the intensity of colors by 30% compared to the previous generation. The E Ink Kaleido 3 uses E Ink Print Color ePaper technology, in which the color filter array (CFA) complements the basis of the E Ink Carta 1200, allowing you to output full-color images.

    Screen lighting system

    MOON Light 2 technology allows you to use the device in the dark or in poor lighting conditions, without any harm to your sight. When using this function, a soft glow of the screen is being created which is optimal for reading in dark rooms. This front light system has a color temperature adjustment, and thanks to the use of Flicker-Free technology, shimmering of the screen is completely absent.

    Swift and Smooth, Follow Your Move

    Thanks to an exclusive GPU and BOOX Super Refresh Technology, you can enjoy a responsive color ePaper screen and increased efficiency.

    Whether you're reading a report or searching for information online, the Tab Ultra C responds instantly to every tap, swipe, and pinch with four refresh modes, boosting your productivity and reducing latency in all types of work. It's also simple to remove afterimages with a blink by using the bottom gesture or navigation button.

    • HD Mode lets you turn pages with the fewest afterimages.
    • Balanced Mode makes it easy to type and read.
    • Fast Mode speeds up page scrolling.
    • Ultrafast Mode helps you use apps and see dynamic content effortlessly.

    High screen refresh speed

    The new graphic processor with BOOST Super Refresh technology provides increased screen refresh speed and smooth movement of objects on the screen.

    See at a Glance What’s Important

    With an HD color ePaper screen, you can distinguish colors and use different colors to mark up the important points on a close-to-paper screen.

    No matter if it's a chart, diagram, or graph, you can easily tell the colors apart and grab the key points with colorful highlights, underlines, and handwritten text. You can also put as many files as you want in the 4GB+128GB storage and read more documents on a MicroSD card.

    And the color books are limitless in the Tab Ultra C, which supports 24 digital formats ranging from PDF to HTML. You can read whatever you want and sync annotations across devices with the same Onyx account.

    Use Colors to Spark Inspirations

    Black and white improve concentration, while colors inspire. The Tab Ultra C with gentle colors combines both and assists you in writing down, organizing, and exploring more ideas.

    Magnetic Stylus with an Eraser

    Taking notes on the Tab Ultra C is a breeze with the Pen2 Pro. You can use the precise nib to select a tool and write tiny strokes thanks to the 4,096 pressure levels. And when you erase on the ePaper screen, the bouncing eraser⁸ will provide a lifelike feeling.

    Dual touch control

    Tab Ultra С has two touch layers. Above the surface of the screen there is a capacitive layer supporting multi-touch, thanks to which you can turn book pages and zoom documents with intuitive finger pinches. In addition, there is a Wacom touch layer under the E Ink panel, so you can make notes and sketches using a special stylus coming with the device. The stylus recognizes 4096 degrees of pressure and allows you to draw with amazing accuracy.

    Work can be Cheerful and Smart

    Working is easy with Android 11 and a powerful octa-core CPU. You can get the app you need, read the content you want, and revel in the allure of subtle but delightful colors.

    And the Work Profile allows you to clone an app and isolate the workplace account from personal use, helping you to maintain a work-life balance.

    Enjoy the Limitless Possibilities

    Tab Ultra C, being an ePaper tablet PC, provides more than just colors. With various helpful features, you may work the way you choose while enjoying smoothness, efficiency, and a long battery life on a single charge.

    Screen auto-rotate function

    A built-in G-sensor automatically selects the correct text orientation when the device is rotated. Thanks to this option, you can change the orientation of the E Reader and the image will be restructured automatically.

    Fingerprint scanner

    The device has a fingerprint scanner integrated into the power on/off button. It identifies the user and ensures the protection of personal data.


    The built-in camera with a 16MP matrix and special software with OCR technology allow you to scan an A4 document, recognize text information and save it to a file in internal memory.

    Long-lasting work

    Low power consumption of the E-Ink display and battery capacity of 6300 mAh provides long-lasting autonomous work.

    Additional screen protection

    Protective glass is located on the E Ink screen and protects it from scratches and other damage. The new glass made it possible to abandon additional screen borders, so the screen is flush with the body of the device. This makes working with this E Reader more comfortable and its appearance is more modern. In addition, a special coating reduces the likelihood of glare on the screen.

    Format Support

    The BOOX software allows you to open many different text and image file formats. While reading, you can change the style and size of the font, the position of the pages, add bookmarks and arbitrarily scale documents.

    Outstanding technical specifications

    The 8-core processor of 2 GHz clock rate together with 4 GB of RAM ensure a comfort work with any even the most complex documents. And 128 GB of non-volatile memory together with support for microSD memory cards up to 2 TB allow you to store a large amount of data directly on the device.

    The device has an audio player so you can listen to music or audio books. For this purpose just run a corresponding file. You also can connect to the E Reader earphones or external speakers both Bluetooth or USB Type C.

    Thanks to the built-in 5.0 Bluetooth module, you can connect external devices.

    The device supports OTG, with which you can connect additional peripherals that do not require drivers.

    Support of languages and dictionaries

    The BOOX allows the user to read documents in different world languages. Amongst them there are such languages as Russian, English, German, French, Spanish, Arabic, Swedish, Chinese, Japanese and many others.

    Easy Shortcuts
