Introducing the Xteink X3, the latest in compact e-readers, which surpasses its predecessor, the X4, in both size and design. This new model boasts a smaller, slimmer profile while showcasing enhancements in its software, button simplicity, and an improved magnetic mount at the back. For those who prioritize extreme portability, the X3 is a commendable option. However, its noticeably slimmer design comes with a significant drawback: the absence of a USB-C charging port in favor of a less common magnetic pogo-pin connection.
This was a disappointing revelation discovered during the unboxing, as the X3 features a variety of improvements that substantiate its title as a worthy upgrade. It measures one millimeter thinner, a few millimeters narrower, and is more than half an inch shorter than the X4. Its dimensions bring it remarkably close to that of a credit card; although it cannot fit into a slim wallet, it easily slips into pockets without contributing any discernible bulk.
At the X4's debut last December, its compact size was just one aspect that captured attention. Xteink marketed the device with visuals depicting it securely attached to a smartphone's back, implying functionality akin to a MagSafe battery, and hinting at a versatile alternative to conventional e-reader cases. However, issues arose with the unconventional placement of magnets on the X4's back, hindering its ability to cling securely to my iPhone 16 Pro, necessitating adhesive metal rings to achieve a satisfactory attachment.
The X3 was greeted with excitement as it perfectly adheres to the back of my iPhone 16 Pro, only to be met with dismay due to its insufficient magnetic strength for reliable fixation. In comparison, other magnetic accessories, such as PopSockets and the OhSnap Snap Grip, create a gratifying “thunk” sound when affixed to a phone. The connection between the X3 and my 16 Pro, however, lacks this reassuring quality, akin to a weak embrace. This inadequacy results in a misalignment of the devices when held together, causing the X3 to detach during pocket transitions.
The X3 features a 3.7-inch E Ink display, which is marginally smaller than the 4.7-inch screen found in the X4 but offers a slightly higher resolution of 250ppi. The reading experience remains subjective and largely depends on individual comfort levels when focusing on a screen of this size. Those who prefer a smaller font may find it essential to wear reading glasses at all times. Conversely, readers who favor a larger font may need to frequently turn pages, as the X3 displays fewer words per screen, making a larger device like a Kindle or Kobo a more fitting choice for them.
While the X3 lacks on-screen lighting and touchscreen capabilities, the organization of its buttons has seen improvement. The device now features a single button on each side for scrolling through menus and turning pages, alongside a pair of two-sided buttons located below the screen dedicated to menu navigation and operating its interface.
Furthermore, Xteink has enhanced the X3’s operating system to display contextual onscreen labels above the front buttons, although they only appear when required.
