This even smaller credit card-sized e-reader has one tragic flaw: why this signal is getting harder to ignore

The Xteink X3 is even smaller and thinner than Xteink’s X4 while also improving on the X4 with refined (but still far from great) software, simplified buttons, and an improved magnetic mount on the back. The piece brings the story back into context and explains why it is worth opening right now. This piece sits on 1 source layers, but the real value is showing why the story should not be skimmed past too quickly.

The Xteink X3 is even smaller and thinner than Xteink’s X4 while also improving on the X4 with refined (but still far from great) software, simplified buttons, and an improved magnetic mount on the back. The piece brings the story back into context and explains why it is worth opening right now. It’s a better compact e-reader than the X4 if extreme portability is your priority, but its slimmer design comes at a terrible price that’s a potential deal-breaker. The Verge is the main source layer for now, and the rest should be read as a signal that is still widening. Changes like this often look small on screen while shifting product habits and day-to-day operating workflows much faster than expected.

What is happening now

There’s a new smallest e-reader in my life. The Xteink X3 is even smaller and thinner than Xteink’s X4 while also improving on the X4 with refined (but still far from great) software, simplified buttons, and an improved magnetic mount on the back. It’s a better compact e-reader than the X4 if extreme portability is your priority, but its slimmer design comes at a terrible price that’s a potential deal-breaker. Instead of a USB-C port, the X3 charges through an uncommon magnetic pogo-pin connection. The main references behind this piece include The Verge.

Where the sources line up

The Verge is the main source layer for now, and the rest should be read as a signal that is still widening. That was a heartbreaking discovery while unboxing the new X3 because it actually comes with a handful of improvements that make it a solid upgrade. The X3 is a millimeter thinner, a few millimeters narrower, and over half an inch shorter than the X4. It’s much closer in size to a credit card, but while the X3 is just a bit too big to squeeze inside my slim wallet, I can slip the two into my pocket without noticing any added bulk. The Xteink X3 is even smaller and thinner than Xteink’s X4 while also improving on the X4 with refined (but still far from great) software, simplified buttons, and an improved magnetic mount on the back.

The details worth keeping

That was a heartbreaking discovery while unboxing the new X3 because it actually comes with a handful of improvements that make it a solid upgrade. The X3 is a millimeter thinner, a few millimeters narrower, and over half an inch shorter than the X4. It’s much closer in size to a credit card, but while the X3 is just a bit too big to squeeze inside my slim wallet, I can slip the two into my pocket without noticing any added bulk. When the X4 first popped up last December, it wasn’t just its size that caught our attention. Xteink promoted the X4 with images of it stuck to the back of a smartphone like a MagSafe battery, seemingly promising an e-reader that went everywhere your phone did and a more versatile alternative to e-reader cases . But the odd positioning of the magnets on the back of the X4 and its size prevented it from properly piggybacking on my iPhone 16 Pro without resorting to applying adhesive metal rings and having it awkwardly hang off the bottom. Changes like this often look small on screen while shifting product habits and day-to-day operating workflows much faster than expected.

Why this matters most

The signal is strong enough to deserve attention, but it still needs to be read as something developing rather than fully settled. With 1 source layers on the table, the part worth reading most closely is where firm facts meet the market's early reaction. The Xteink X3 is even smaller and thinner than Xteink’s X4 while also improving on the X4 with refined (but still far from great) software, simplified buttons, and an improved magnetic mount on the back.

What to watch next

The next thing to watch is rollout speed, regional limits, and whether the update really changes day-to-day habits. Patrick Tech Media will keep checking rollout speed, user reaction, and how The Verge update the next pieces. In this pass, the story was distilled from 1 signals into 1 source references that are genuinely useful to readers.
