Xteink X4 Pro vs X4 vs X3: Which Pocket E-Reader Fits Your Routine?

You may be looking at three similar names and wondering whether “Pro” simply means “get this one.” It does not have to. The useful question is the moment that normally stops you from reading: low light, a device that is too cumbersome to carry, or an interface that does not feel simple enough to pick up.

XTEINK’s current comparison places the three models in distinct lanes: day-and-night reading for X4 Pro, daily focused reading for X4, and ultra-light portability for X3. That is a more useful starting point than a generic feature count.

Choose the reading moment you repeat

If you regularly reach for a book on an evening train, in a dim room, or after the lights are down, X4 Pro is built for that routine. If your reading is mostly in ordinary daylight and you want the same 4.3-inch format with buttons, X4 keeps the decision simpler. If the reader only works when it disappears into a pocket or stays almost unnoticeable beside your phone, X3 is the more direct fit at 58g and 3.7 inches.

Current official comparison checked July 28, 2026. Product availability can change.

All three are pocket readers with magnetic backplates and 16GB storage expandable to 256GB on XTEINK’s current comparison page. Those shared foundations matter: this is not a choice between a “real” reader and a lesser one. It is a choice about which compromise you will notice every day.

Choose X4 Pro when reading should not end with daylight

X4 Pro earns its name when the front light is more than a nice extra. The official page lists adjustable brightness and warm/cool light, so it can stay in the same pocket-reader role from daytime into lower-light moments. It also combines touch navigation with physical page-turn buttons rather than asking you to commit to one control style.

That makes it the strongest fit for readers whose opportunities to read are unpredictable. You may prefer buttons once you are settled into a chapter, then touch when you are looking for a book or changing a setting. The 4.3-inch screen keeps the same compact category as X4 while adding that flexibility. For a product-only look at those X4 Pro features, see the X4 Pro front-light and touchscreen guide; this article is about choosing among all three models.

There is one important boundary. At this check, the official X4 Pro page lists $99 and says sold out. The $30 difference over X4 or X3 makes sense only if the front light or dual-control setup is something you will actually use. If almost all of your reading happens in comfortable daylight, “Pro” alone is not a reason to wait or spend more.

Choose X4 when you want the larger button-first format

X4 is the clean middle path. It keeps the 4.3-inch display and physical buttons but leaves out the front light and touchscreen. For a reader who has already decided that reading happens in daylight or well-lit places, that is a direct, focused version of the larger pocket format.

The point of X4 is not to imitate X4 Pro at a lower price. Its current official positioning is “daily focused reading.” That suits a reader who wants more page area than X3 offers, prefers a button-led interaction, and does not need to make a dim room part of the device’s job.

At $69 on the current collection page, it lets the $30 difference stay attached to a real question: will a front light and touch change your routine often enough to matter? If not, the more direct button-first model may be the better fit.

Choose X3 when carrying it is the deciding factor

X3 is the smallest option in the current line: 3.7 inches and 58g. If the reader needs to ride on the back of a compatible phone, live in a small pocket, or come along on short errands without planning around it, X3 answers a different problem from X4 Pro.

The reader who will get the most from X3 is protecting a habit: a few pages while waiting, commuting, or taking a break. Choosing the device that is easiest to bring can be more useful than choosing the device with the longest feature list.

X3 is not simply the lower-feature choice. Its smaller 3.7-inch form is a deliberate answer for someone who values a reader that stays out of the way until the small reading window arrives. If portability is what keeps the habit alive, that boundary is more useful than paying for flexibility you will not use.

Do not let a specification table choose for you

• “I want to read after the room gets dark.” Choose X4 Pro.
• “I want a larger little reader with a simple button-first setup.” Choose X4.
• “I only read when I can carry the device without thinking about it.” Choose X3.

This is why the three models can coexist. A 72g X4 Pro is not automatically the better choice than a 58g X3, and X4 is not a placeholder between them. Each model protects a different kind of reading consistency.

What stays the same across the line

It is easy to overstate the differences. All three products are compact E Ink readers rather than large tablets. The official comparison lists 16GB storage expandable to 256GB and magnetic backplates for each model. If a particular file type or transfer workflow is essential to you, check the current product page before choosing.

You do not have to buy X4 Pro to get the pocket-reader concept. Choose it because day-and-night flexibility and touch plus buttons fit your routine; choose X4 or X3 because their narrower jobs fit better.

A useful way to make the decision is to begin with the feature you would miss most: a front light for lower-light moments, the larger button-first layout, or the lowest carry weight. Starting there prevents a familiar product name or a longer feature list from deciding for you.

Before you compare every row, picture one ordinary week. If you read in daylight and never need a lit display, X4 Pro’s extra flexibility may not change your experience. If a reader stays at home because it feels too noticeable to carry, even a better feature list will not repair that habit; X3’s smaller, lighter form may. If you want the larger compact screen but prefer a button-first approach, X4 keeps the choice focused. The goal is not to rank the models from least to most capable. It is to choose the friction each one removes for you.

That is also a more durable comparison than choosing only by launch order, promotional language, or a feature that looks useful on paper but never enters your own reading routine.

The practical verdict

For the reader who wants one compact device to cover both a bright commute and a lower-light reading window, X4 Pro is the most complete XTEINK option. For a 4.3-inch, button-first reader for everyday focused reading, choose X4. When the device must stay as light and small as possible, choose X3.

X4 Pro is currently listed as sold out, so this is not an instruction to buy immediately. If the day-and-night reading path is yours, check its current status. If it is not, the useful outcome is simply knowing that X4 or X3 may be the better reader for your routine.
