XTEINK X3 vs XTEINK X4, Which Tiny E-Reader Should You Actually Buy?
The XTEINK X3 and X4 both chase the same pocket e-reader idea, but the X4 is the easier recommendation for most people while the X3 is the one to buy if you want the smallest setup possible
Quick Take
- Buy the X4 if you want the safer pick with the slightly larger screen and fewer compromises.
- Buy the X3 if the whole point is getting the smallest, lightest dedicated e-reader you can stick in a pocket every day.

If you want the short answer, buy the XTEINK X4 unless you already know the smallest possible size is the whole reason you are here.
That is really the split. The X3 and X4 are both part of the new pocket e-reader wave that is getting so much attention in 2026, but they are aimed at slightly different buyers. The X4 is the better tiny e-reader for most people. The X3 is the more extreme version for people who want maximum portability above everything else.
The quick comparison
Why these are suddenly popular
Tiny e-readers are catching on because they solve a real problem. Phones are always with you, but they are full of distractions. Traditional e-readers are better for actual reading, but they are easier to leave at home. The X3 and X4 both try to close that gap by turning dead time into reading time with something small enough to carry every day.
That is why this category has shown up in mainstream coverage this year. Pocket-sized e-readers have been framed as a direct answer to screen fatigue, doomscrolling, and the general desire for more focused devices.
Where the X3 wins
The X3 wins on portability, full stop. It is lighter, thinner, sharper on paper at 259 PPI, and a little more interesting if you like niche gadgets. It also adds gyroscope page turning and NFC, which make it feel like the more experimental and enthusiast-friendly device.
If your ideal outcome is a reader that feels tiny enough to forget in your pocket, the X3 is the better fit.
Where the X4 wins
The X4 wins on usability. The 4.3-inch screen does not sound much bigger, but at this size it is a meaningful upgrade. It is still tiny, but it is less compromised.
That is why the X4 is the easier recommendation. It still delivers the whole point of the category, but it feels more practical as something you might use every day rather than just admire for being unusually small.
Which one should you buy?
Buy the XTEINK X4 if you want the better all-around pocket e-reader. Buy the XTEINK X3 if you want the smallest and lightest one no matter what.
