What are the differences between the Boox Tab Ultra C & the Tab Ultra C PRO?

Boox recently launched a PRO version of their popular Tab Ultra C e-ink tablet.

In this post, I want to quickly go over the similarities and differences between these two devices.

First the similarities….

Both the Tab Ultra C (TUC) and Tab Ultra C Pro (TUCP) use the same colour screen (10.3″ Kaleido 3). They have the same 128Gb storage capacity and have a frontlight (with warmlight), speakers, microphone, g-sensor, rear camera, MicroSD card slot, Bluetooth, wifi, and fingerprint scanner.

They both have an onboard graphics processor and use Boox’s proprietary Super Refresh technology.

They have the same physical dimensions, both run the Android operating system, and both have the same native apps.

So, what are the differences?

The first difference is that under-the-hood, the Tab Ultra C Pro is technically more powerful.

The TUCP has a 2.8GHz processor (compared to 1.8GHz on the TUC). It also has 6Gb of memory compared to the TUC’s 4Gb. This means that the TUCP should be more powerful for more demanding use cases (however, whether this much power will be needed by the average user, or is simply overkill, remains to be seen).

Although both e-ink tablets run Android, the TUCP has Android 12, whilst the TUC has Android 11. I must admit that I’m not all that knowledgeable about Android versions but Android 12 should bring improvements to performance, user interface, security, and privacy. At the very least, it means that newer apps are more likely to work on the TUCP.

The original Tab Ultra C has a larger battery (6300mAh) compared to 4600mAh on the Tab Ultra C Pro.

Next, there has been a slight improvement to the camera (although the camera ‘bump’ on the rear panel is still present). There’s now an LED flash for snapping higher quality images of documents, which will hopefully improve the OCR function.

Boox has also added physical volume (up/down) buttons to the side of the TUCP – there were no volume buttons on the TUC. As a sidenote, I’m interested to find out if they can double-up as page-turn buttons.

Although the physical footprint is identical, it has been made around 30g lighter. Another sidenote: I wonder if the new keyboard folio is also lighter because that did add a lot of weight to the original Tab Ultra and Tab Ultra C?

Which links nicely onto the TUCP’s new keyboard case. The pogo pins on the TU and TUC were located on the bottom edge. They have now been relocated to the back panel, which promises a more secure connection. The TUC does occasionally have intermittent connection issues with the keyboard folio, so this is a welcome addition. The keyboard folio also has a trackpad on it, which means that you can navigate around the operating system and access features with customizable gestures. Finally, the tactile feel of key pressing has been improved and there is an LED light on the Caps Lock.
