There are devices that, in their first version, manage to capture the industry's attention and are capable of changing an entire sector. Xteink achieved this a few months ago with the X4, and without time to absorb all the changes that an e-reader could achieve by minimizing its size, they've decided to release a new version that goes much further in several ways. We've been fortunate enough to be among the select few worldwide to get our hands on the first version of the new Xteink X4 Pro before its official release.
The first impression is physical: this device weighs about as much as a handful of coins and fits in any pocket without being bulky. Once you have it in your hand and the size seems ideal, it's time to turn it on. Swiping your finger across the e-ink screen, something unthinkable in the previous generation governed entirely by buttons, completely changes the way you interact with the device. Xteink has rewritten its operating system from scratch for this occasion, and it shows: the menus respond to touch, folders open with a gesture, and even the power-off wallpaper, which you can customize to your liking, is changed by tapping and holding the chosen image.
A discreet and different electronic book reader
It hasn't abandoned, however, a certain functional nostalgia. The X4 Pro retains two physical buttons for turning pages, one on each side, designed for those who still prefer the crisp click of a key when sliding across glass. And it adds a discreet, almost invisible home button that centralizes the return to the main screen. It's a device that straddles two generations of users without completely abandoning either. The combination of touchscreen and physical buttons makes it a hybrid that satisfies both traditional users and those seeking a more modern interaction.
Magnetic charging and autonomy
The charging section is another plot twist. The direct USB-C port on the reader itself is gone—a controversial but necessary decision to free up space—and replaced with a magnetic port with an integrated magnet. This allows the device to be attached to compatible surfaces and charged using the included Pogo Pin to USB-C adapter. The 1.100 mAh battery promises several days of reading with typical use of one to three hours per day, and the charging indicator—red while charging and white when fully charged—is one of those small details that nighttime readers appreciate. Magnetic charging and multi-day battery life make the X4 Pro an ideal companion to always have with you.
Content management and connectivity
Content management also takes a leap forward. Cloud synchronization allows you to upload books, images, and fonts from the Xteink app and see them automatically appear on the reader as soon as you connect to your home Wi-Fi. The classic microSD card option, included as standard and already inserted in the device, remains available, as does direct wired transfer. Three paths to the same destination: filling the X4 Pro with seamless reading material. The cloud, microSD, and wired connection offer options for all preferences, making it easy to access content from any source.
Availability in Spain
The Xteink X4 Pro has arrived in Spain as one of the most anticipated new products of the year for minimalist digital reading enthusiasts. Buyers will also receive a free magnetic case with their purchase. Meanwhile, the original X4 model remains available, as confirmed by the company, so those who prefer the traditional USB-C connection or a slightly larger size still have that option. The Spanish launch includes the free case and the choice between the X4 Pro and the standard X4.
In practice, the X4 Pro isn't meant to replace the large e-readers on the market, but rather to be a companion device: the one you carry in your coat pocket, the one you pull out on the subway without needing to turn on your phone, the one that transforms dead time into reading time. Xteink has understood that the next frontier for these devices wasn't more screen size or more power, but a more natural interaction. With this touchscreen, gesture and reading finally begin to speak the same language. We've already tested it. Now it's up to the reader to decide if they want to join this new, more tactile way of turning pages.
