Xteink X4 Pro: Price, Specs & What's Confirmed

The wait is over: the Xteink X4 Pro went on sale July 21, 2026, at $99 on xteink.com: the front-lit, touchscreen refresh of the X4 that the community called the “X4 V2 Pro” or “X4P” while it was rumored. The launch confirms almost everything the leaks said (front light, touch, 1100 mAh battery, pogo-pin charging) and adds two things nobody reported: an explicit unlocked-firmware guarantee covering every unit sold on the official store, and a 500-unit first batch that sold through on day one. This page is the launch hub: confirmed specs and price, what changed versus the X4, what the community actually thinks, and the honest buy/wait/stick call.

Price, Stock, and the First Batch

Confirmed on xteink.com, July 21, 2026

The X4 Pro is live on the official store at a $99 launch price against a $109 list price (9% off), in one color: Space Black. Two launch-window notes from the product page:

• Free magnetic case with launch orders (random color; the case sells separately for $8.99 in six colors).
• Stock has been intermittent. The 500-unit first batch sold through on launch day, and the Pro has cycled in and out of stock since, listed at $99 in Space Black. As of August 7, 2026 the product page still shows it sold out: the restock it had listed for August 6 came and went without stock landing (or sold through immediately), no new date is posted, and the page now offers a notify-me email form. Check the page for live availability before ordering.
• It is not on Amazon. The Pro is currently xteink.com-only. A US retail listing is expected (the FCC filing points that way), but none has appeared yet, and buying from the official store is what carries the firmware guarantee below.

Buried at the bottom of the product page is the launch’s most under-reported line, quoted verbatim:

Unrestricted Firmware Guarantee: “All units purchased directly through the XTEINK official website are exempt from third-party firmware restrictions. This commitment applies to all past and present models, with no planned changes for future updates.”

After a year of locked-vs-unlocked lottery depending on which seller you bought from, that’s Xteink formally committing that official-store units, X4 Pro included, ship unlocked and stay that way. It doesn’t make the Pro cross-compatible with community firmware (more on that below), but it removes the biggest roulette wheel in the Xteink buying experience.

One box-contents gotcha: the Pro ships with the device, a quick-start guide, a 16 GB microSD card, a matte screen protector, two adhesive metal rings, and a magnetic charging adapter, but no charging cable. The adapter turns a USB-C cable you already own into the pogo-pin connection; if you don’t have a spare cable, budget for one.

Confirmed Specs

From the official product page, not the leaks

Three things to notice in that table. The Pro is shorter, thinner, and lighter than the X4 despite the bigger battery. Losing the bottom button row is most of the height difference, and it’s why X4 cases and screen protectors do not fit the Pro (the accessory threads figured this out from the dimension sheet; the official X4 Pro magnetic case and protective case are separate SKUs). The 219 PPI panel is the same sharpness class as the X4: fine for English, but CJK readers in the spec thread were hoping for ~300 PPI for ruby characters and didn’t get it. And the chipset is still not disclosed: Xteink publishes the OS (XTOS), not the silicon.

What Actually Changed vs the X4

The two most-requested features, one controversial trade

• The front light is real and dual-tone. Adjustable brightness plus warm/cool temperature: the single most-requested X4 feature, and the entire reason most buyers will choose the Pro. It can be turned off entirely.
• The touchscreen replaces, rather than supplements, the button layout. The X4’s bottom/front buttons are gone (hence the shorter body). You get tap-and-swipe navigation plus two side page-turn buttons (left = back, right = forward) and a home button hidden front-middle. Can you disable touch while reading? Owners now say yes: “There is already an option to turn off the touchscreen while reading.” Xteink hasn’t documented the exact toggle and no press reviewer has walked through it, so treat it as owner-reported (shown in the launch trailer), not vendor-confirmed.
• USB-C is gone. Charging and data now go through a pogo-pin connector with a magnetic adapter in the box. This is the launch’s biggest complaint: covered in the next section.
• Bigger battery, bigger storage. 1,100 mAh (up from 650) and a 16 GB card in the box with 256 GB expansion support.
• Same software family. XTOS, Xteink’s own non-Android OS, not the Android pivot the S4 represents.

If you want the full owner-decision version of this section (who should upgrade, who should stick), that’s the X4 Pro vs X4 decision below.

What the Community Thinks

Launch-week sentiment: torn, not hyped

We’ve read through the launch threads so you don’t have to: the 315-upvote spec comparison, the 369-upvote leak thread, and the brutally honest “torn about the X4 pro” on r/xteinkereader. The mood, ranked by how much it should influence your decision:

1. The pogo-pin charger is the loudest objection. The top comment on the spec thread (81 upvotes): “the removal of usbC to pogopin alone is enough for me to stay with X4. I dont want to be having a dedicated charger.” Another owner put the irony well: “The previous deal breaker was lack of a light, they give us that, but then add in a different deal breaker lol.” The counterpoints: the four pogo pins do carry USB data (the X3 flashes firmware through its pins), the adapter is included, and at 1,100 mAh you’ll charge infrequently. But if “one cable for everything” is a hard requirement, this is a real regression.

2. Touchscreen fear is really contrast fear. Many X4 owners love the device because it’s button-only, and worry a touch layer washes out the X4’s praised contrast: “On the videos with frontlight they seem to look bad in terms of contrast. I’d wait for actual hands on reviews.” Others point out the upside, dictionary lookup is miserable without touch, and Boox/Kobo owners in the threads say they’re switching for the front light. This one won’t be settled until real-unit photos and reviews land; it’s the top thing we’re watching.

3. “$99 is Kindle territory.” Several buyers note the Pro’s price meets discounted Paperwhites head-on: “Add that onto a $99 price and you’re literally into Kindle territory”, with replies pointing at a $125 Paperwhite at Best Buy. The devices aren’t really rivals (pocket/minimal vs mainstream/ecosystem), but the price anchor is fair, and it’s why the Kindle comparison now matters more, not less.

4. The wait camps. The threads split into people waiting for CrossPoint support (“wait until cross point is ready and proved working on the pro”), waiting for the S4’s Android, waiting for a white version (a white render appears at the end of Xteink’s official launch video, and at least one reviewer says a light-grey unit is on the way), and a vocal group wishing for an “X3 Pro” instead. A fourth group simply bought the OG X4 because of the Pro’s changes: “Just bought the og X4 because of all these unnecessary changes.”

The summary judgment of the launch, from the community itself: “All you had to do was add lighting 💀”, the most-upvoted sentiment on the official video thread. If you’re in that camp, the device you actually want might be the leaked X4 Gen 2.

First Hands-On Impressions

Pre-launch review units — treat as provisional

The only full hands-on so far is Joshua Lowcock’s first review of the X4 Pro, from a pre-launch Chinese-market unit. His findings, with the caveat that launch firmware may already have moved:

• The touchscreen is a visibly cheaper part. “You can see the touch screen layer from certain angles. It’s like small microdots on the screen.” Response was laggy on his unit, and his verdict was blunt: “I would not buy the XTEINK X4 Pro yet until they fix the touch lag.”
• The front light works, but his pre-launch unit had a battery scare. Brightness and color temperature both adjust, but he hit “wildly fast battery draining issues” (“drained in minutes”) that he suspects are a software bug, plus some light leakage around the bottom edge. Treat that as provisional: it was pre-launch software, and a retail-unit video review reports the opposite, that the Pro’s bigger cell “helps offset how much more of it the front light uses up” and it charges infrequently in normal use.
• What’s in the box matches the launch listing, and MagSafe-style magnetic mounting works.

His overall advice, “I’d honestly hold on the X4 Pro for now”, was written against pre-launch software on a first-run unit. Whether it holds against retail firmware is exactly what the first owner reports will tell us. None of this is our own testing (we don’t have a unit yet), so treat it as reported, not verified.

We’re buying an X4 Pro from the first available batch and will test the three claims that decide this device: touch latency vs the X4’s buttons, front-light uniformity and contrast against the X4’s panel, and real battery life with the light on vs off. Results will land here and in the battery owner-test post.

Naming, Untangled: V2 Pro vs S4 vs Base X4

"X4 Pro" is the official name — and it is not the S4

While it was rumored, the community called this device the X4 V2 Pro, X4 Pro, or X4P: three names for one product (the FCC model 2BTR9-X4PRO ties them together). Xteink’s launch settles it: X4 Pro is the official name. If you landed here searching “X4 V2 Pro,” you’re in the right place.

What the X4 Pro is not: the S4, which is Xteink’s separate Android-11 pivot (reported on sale in China at CNY 339, with no international release planned as of August 2026), and not the base X4, which stays on sale at $69 with its full button row and USB-C. The Pro is best understood as “the X4 with a front light and touch, still running Xteink’s own OS.” The X4 vs X4 Pro vs S4 comparison lays out the three-way split.

The X4 Gen 2 Leak

The button-purist alternative — still unofficial

Five days before launch, an AliExpress seller leaked what look like Xteink’s own product-line slides, and they include a device nobody expected: an X4 Gen 2, a lighter refresh of the base X4 with no front light and no touchscreen. That’s precisely the “just add nothing and keep it simple” device the button loyalists are asking for, and The eBook Reader’s coverage notes Xteink appears to be keeping the plain-button line alive rather than replacing it.

Treat the details as unconfirmed. The eBook Reader flags the leaked images themselves as inaccurate, “the buttons are wrong”, and the weight and battery figures floating around (roughly 68 g, 920 mAh) aren’t corroborated anywhere, so we don’t print them as fact. Nothing about the Gen 2 is official: no date, no price (the thread relays a $69–79 rumor), and no word on whether it keeps USB-C. But if the Pro’s touchscreen and pogo pin are deal-breakers for you, “wait for Gen 2” is now a rational position rather than wishful thinking.

CrossPoint and Custom Firmware

Two separate questions: locked units and community firmware

Locked units: the Unrestricted Firmware Guarantee means official-store X4 Pro units ship free of third-party firmware restrictions: the first time Xteink has said that in writing for the whole store. That’s a stock-firmware freedom guarantee.

Community firmware (CrossPoint et al.): a different question with a less satisfying answer. CrossPoint does not run on the Pro yet: the touchscreen, front light, and a real-time clock are all new hardware to support. But porting groundwork has begun: an open pull request (#2675), created July 22, migrates the UI to the FreeInkUI library and is described by the maintainer as “the base for the x4Pro work.” That’s a started branch, not a working port, and it’s a stated purchase gate for part of the community (“wait until cross point is ready and proved working on the pro”). Keep the two promises separate: the Unrestricted Firmware Guarantee is a legal commitment that official-store units won’t be locked, not a sign CrossPoint runs on the Pro today. We’re tracking the port on the firmware directory.

What We Still Don’t Know

The launch answered a lot — not everything

• The chipset is undisclosed, as always with Xteink. And to kill an old rumor: claims that the Pro runs a Linux-based OS on an Allwinner F1C100s/F1C200s have no source and contradict every tracker. The chip is simply “not disclosed.”
• Touch-disable while reading: owner-reported yes, but not vendor-documented or walked through by a reviewer.
• White/other colors: a white render exists in the official video and review units in light grey have been reported, but the store lists Space Black only.
• Amazon availability: the FCC filing (2BTR9-X4PRO, submitted June 15, 2026) points at US retail plans, but the Pro remains xteink.com-only for now. No Amazon listing has appeared yet.
• Real-world contrast and battery with the light on: the two things no spec sheet can answer, and the heart of our planned owner test.

Should You Buy, Wait, or Stick with the X4?

The honest call for launch week

If you’re torn between the shipping options themselves, start with the X3 vs X4 model choice and the pre-purchase reality check. The Pro doesn’t change what the X3 and X4 are good at.

Last updated: August 3, 2026. Aug 3 patch: re-verified the live product page: the Pro currently reads out of stock at $99, and it has cycled in and out of stock since launch, so availability is now phrased as intermittent rather than a fixed in-stock stamp; the $99 launch / $109 list price is unchanged. July 22 patch: the Pro is back in stock at $99 (Space Black) on xteink.com: the sold-out/"the 23rd" restock language is gone; CrossPoint porting groundwork has begun (PR #2675, "the base for the x4Pro work"), kept separate from the legal firmware guarantee; touch-disable is now owner-reported (not vendor-confirmed); the battery framing is balanced with a retail-unit review; and the X4 Gen 2 leak is flagged as unreliable ("the buttons are wrong," specs uncorroborated). Launch-day rewrite: the X4 Pro is on sale at $99 (list $109) with a free-case offer, a sold-out 500-unit first batch, and a restock dated "the 23rd." Every "reported" spec from the pre-launch era is now confirmed against the official product page, and the Unrestricted Firmware Guarantee is quoted verbatim. Added a community-reaction section mined from the launch threads (pogo-pin, contrast, price, wait camps), the case-incompatibility answer, and the CrossPoint status. Earlier pre-launch reporting (embargo, FCC filing, AliExpress leak) is preserved in condensed form for the record.
