I got one, it's pretty cool that it's small enough to just magnet to the back of your phone. If your someone who needs to use a large font on their ereader to read its certainly not for you, but the screen size is good enough for regular sized text.
I would like to see a phone case which this inserts into --- bonus points if there's a way to use it as a status display for the phone for use in bright/direct sunlight.
The obvious innovation is to just make the back of the phone case an eInk display. No need for all the bulk when you can merely have an app on your phone that controls the case-display and the phone can output whatever reader app you want to it like a companion/IoT device.
Or it can be a little bit bulkier and just be a dedicated ereader that is shaped like a phone case. Either way works.
Yeah but I’ve seen color e-ink fridge magnets that are like $30. I don’t think it ends up being more expensive or substantially worse for the environment than people buying cases made of fancy leather. Presumably the display module could also be cut out of it for DIY uses.
I've had the X3 for a month and I love it. It's so small I forget it's in my pocket and have almost washed it a couple times. I'm working on custom firmware for it, so I ordered an X4 when they had the 20% off sale to test on there too.
I'm a noob so I haven't got very far yet. Currently working on a bootloader then going to do flashcards and a very basic word processor. I'd like to be able to switch firmwares almost like switching applications. I'll share everything on GitHub once I'm sure it won't brick people's devices, but right now the code is just sitting on my PC.
I got the X4 and liked it enough that I used it a ton even though it turned out to be too big to Magsafe onto my phone. In fact, I liked it enough that I also got the X3 on sale so I can use it the way I originally intended to use the X4.
For those who can afford it, I can recommend the Boox Note for the ebook reader. It comes with full Android, so you are not limited to books but can read news, Hacker News, and other doomscrolling that fills the Internet.
In a pinch, you can also connect it to a Bluetooth keyboard and use it as a development terminal. SSH terminal looks gorgeous on e-ink.
the point of having an e-ink reader (at least for me and anybody I know who actively use such device), is to read things, so keeping doomscrolling options is *not* an advantage..
Android is nice because it expands the reading options somewhat with the existing app ecosystem. A browser with reader-friendly features like einkBro is something that other devices don't have, but is available easily with no cross-compiling or other tedious activities on android. Reading articles and blog posts page-by-page without the visual interrupt of scrolling is a much better experience for me. Doing everything on-device saves me from having to run various daemons and webservers and browser plugins and constantly switch between machines to keep things in sync.
> It comes with full Android, so you are not limited to books but can read news, Hacker News, and other doomscrolling that fills the Internet.
That sounds like an anti-feature. When I first bought an ereader over 15 years ago, I intentionally chose one that didn't support Wifi for this very reason. I want it primarily for reading documents.
But then again, I guess Boox is meant more to be a tablet than an ereader.
Also, genuinely curious - does having Android reduce the time between recharges? As an example, I read a whole book over 7 days, and didn't need to charge my Kobo (and modern Kobo battery life is not great).
I want Kobo to release an 8" color, but don't know if they ever will. I was considering Boox as an alternative, but I worry about battery life and Android. I wonder if my worry is misplaced.
Boox devices vary on battery life. The thin ones usually have ~12h of reading time per charge and don't lose as much charge while sleeping as android phones do, but a bit more than a kobo. The batteries size is optimized to be just big enough that charging is not particularly burdensome in practice. My only complaint is the flat bezels which are no good for fragile eink screens.
I have a boox device (go Color 7 gen 2) and the battery life is not good for an ereader. For a tablet, it's fine I guess but I actually get more battery life from my actual tablet than this little ereader.
it lasts a day if youre reading all day, a couple days with lighter use. I couldn't finish a whole book on a single charge even if its a small book. Not at my reading speed anyway.
As a comparison, I've already read 3 books on the xteink x4 and still have 60% of battery left. So yeah, android is good but these things need much better batteries to compete.
If you are looking for a more affordable option, I have a Musnap Ocean C. It's a little bare bones, but still pretty good. It's a color e-ink display and you can get an optional pen that lets you take notes. I only use it for books and documents, though. It's the best option under $300 that I have found if you want something that is color and can take hand written notes.
A problem with Boox that some here care about is their non-compliance with the GPL. Their devices run modified GPL software and they have (AFAIK) refused to release their modifications.
I skimmed over the project a bit. It seems quite ambitious to aim to reimplement epub, considering that means supporting HTML, CSS, SVG and JavaScript.
Is there a ebook format that isn't just build arround the concept of a webbrowser?
While I agree in terms of modern browser expectations (and books absolutely should not need JavaScript), I think books in HTML makes a lot of sense. HTML was meant for sharing text documents, after all.
Got the X4. Put CrossPoint on it. Works like a charm. The http server accessible over wifi makes transferring books extremely simple. (Shame on the Kindle for locking everything down.) This is proof-of-concept that a microcontroller is more than enough for something like an e-reader.
I have a Kindle and a Kobo. They are sturdy devices. But the X4 is the one that is a genuine e-reader. Would not get it as my one and only e-reader though as you tend to miss the size and backlight of the larger ones.
What would I want from future iterations?
- backlight even if it compromises on battery a bit
I'm with you on every bit. I love my Kobo Libra 2 and it lives on my nightstand table. It's an excellent reader. The X4 with CrossPoint is an alright reader, but I've been chewing through books on my morning commute because it fits in my jacket pocket and I can have it out on the train without bumping into other people.
It's not the best reader I own, but it's the best reader I have on me at any given moment when I'm not laying in bed.
Not the commenter you were replying to, but I have both a Kindle and a X4. No, it does not, but searching for a unique enough phrase (just two or three words) on the current page gets you there fast enough.
As someone who also juggles multiple readers, I find it easier to have a different book per device. Otherwise I would waste too much time trying to sync between the two.
Yes. I read multiple books in parallel. Each on a different reader. So syncing is not something I usually need though I did build myself a local sync server for fun.
If you install koreader on the kobo, crosspoint on the x4 and create a free koreader sync account (or host your own sync sever): yes - but on the x4 you need to manually trigger syncs
Alternatively if you wish to stick with the stock Kobo reader app it is possible to sync via a https://grimmory.org/ instance
> It's not the best reader I own, but it's the best reader I have on me at any given moment
This. The form factor is almost the right one for an e-reader. The battery lasts for weeks. It is so open that you could probably write your own firmware for it based on CrossPoint or similar for your own needs.
Needs some iterative development while ruthlessly culling requests for random features.
> The form factor is almost the right one for an e-reader.
It truly is. It fits perfectly in one hand without stretching uncomfortably, so I can hold it for longer than any reading session I've had without making my hand get stiff. While holding it in the normal way, my thumb naturally rests on one of the side buttons, which I've mapped to "next page".
If I were to hold out my hand, and someone put an X4 in it, I wouldn't have to move a muscle and it'd be in the right position for me to read for hours with just the periodic button tap.
Everyone's different, of course. It's guaranteed to be too big or too small for others, and that's cool. For me it feels like someone custom designed it based on a model of my hand.
crosspoint has started developing a little slower now that its in a really usable state.
I've merged some working PRs onto my device and it's working great. I really needed a dictionary option because I like to quickly know the meaning of words as I read.
its fine. theres a few more things that could be nice (reading statistics for example) that other forks do have.
I bought it because it was comparatively dirt cheap and was hackable. I was delighted at how nice it actually was to use. I figured it'd be crappy in some ways, but, you know, at least it was cheap. To the contrary, it's perfectly fine and does a great job at letting me flip through ebooks.
What it's not good at it showing any kind of diagrams, because even if the software was decent, it's a relatively tiny screen. I haven't even bothered trying to view a PDF on it and don't know if that's supported. For epubs I've uploaded to it through Calibre, it's utterly adequate.
Not being lighted is what has kept me from trying it. If they do add lighting I hope it is a front light and not a back light. Hard to beat a front lit e-ink display for reading. Bonus points for warmth settings.
if its still as open, I'm pretty sure the touchscreen can be worked out to work well.
but I really agree with you, I'd love to have a frontlight on it. That's literally all I'd wanted over the current device. No touchscreen necessary.
but between touchscreen + frontlight and neither, perhaps I'd be willing to have a touchscreen so long as the software is good (which something like crosspoint I'm sure would nail)
Yeah I really like not having a touchscreen that I have to worry about bumping while I'm reading, a backlight is the only addition I would enjoy to the current x4
Every item you add to the device adds a failure mode. Light is fine. Touch ... I don't know. I like the tactile feel of buttons.
And Android means the device no longer runs on a microcontroller which has consequences for battery life etc. As long as they keep the original, minimal model active with minor QoL improvements, I guess it is fine.
It was probably a decade ago, but I used to have this extremely cheap e-reader that ran off AA batteries, used a monochrome LCD screen (no lighting) and was based on a microcontroller. If you let the batteries die and waited too long to replace them, you had to reflash the software on it. I think it only handled mobi format, but it might have been epub.
I love my X4 as well, and would love a backlight. Crosspoint and its downline forks are great.
the only funny thing about the X4 is reading it in bright sunlight. it will corrupt the image on the screen on page turn unless you shade it? something to do w/ older eInk screens and not having a UV Filter. weird, slightly annoying.
Question to X4 owners - what is the benefit over a smartphone?
I have a kindle for beach and travel as a good compromise size; I use my 10" tablet when I really settle in for reading, or when I read technical books with graphs or books with photographs etc. For my adhoc reader I use kindle app on my phone. What is the unique selling point of something like X4? I notice it attaches to the phone which seems bizarre, phone feels like a functional superset, so I must be missing something - is it battery life or less distractions or something else?
I'm specifically wondering about the X4, which is the size of a phone, meant to be attached to the phone, but it's not a phone and crucially no backlight. Does it specifically fill a situation for people who don't want to carry a phone but will carry this? Or, for people who might carry x4 and a smart phone, why read on the x4?
It's way smaller than modern phones, though - I clip mine to the back of my Samsung (magsafe case) and it only blocks one of the five cameras. (phone: 288g xtelink x4: 75g.)
(also: hasn't the x4-v2 already been announced that is supposed to have a frontlight?)
(having it right there mostly serves as a physical token/reminder that I don't want to get sucked in to my social media and other phone apps as much, so if I'm just using it to fill "politely waiting" time I can just grab the x4 instead. I also have a trivial pandoc-generated epub todo list as the first document, though that would work better as a crosspoint fork/feature really...)
You read on a phone and on a tablet, so the X4 probably isn't for you. I hate reading for long periods on LCD screens. I have to do it all day at work and I don't want to do it at home. I read on a kindle unless I really need a computer screen for photos or graphs. I am just not going to pull out my phone to read a book, so an X4 sized device makes it easier to have a book with me. Since phone reading doesn't bother you, I doubt you would get much out of an X4.
- The e-ink screen is great for reading. The feeling of ink on paper it produces cannot be replicated on any other screen. Not to my satisfaction.
- The microcontroller is so weak that you cannot add crappy features like more powerful e-readers are wont to do. This produces minimal distraction-free UIs. No messaging, no browsing.
- The form factor is the biggest win. It fits in a pocket and is great for the 5-10m you find when traveling or waiting somewhere. I cannot carry e-readers that way.
- It is great for fiction, and text-heavy non-fiction: history, philosophy etc. Stuff with a lot of images, tables, code blocks etc ... nope.
I carry my phone and my X4 in the same pocket. Whenever I feel like doom-scrolling, I take out the X4 and read a chapter in a book instead. It is excellent for taking back time to read that I lose to my phone.
Sure I could read the same book on my phone, but it takes multiple steps to open the e-reader app on my phone. On top of that, there are half a dozen other things I could open on my way to opening up my e-reader app. With X4, I press the button on the side and I'm reading.
Is it the best ereader? Not at all. Reading whitepapers or programming books on it is a fools errand. It is great for anything that is mostly text. Novels are amazing on it. I've keep up with my read it later backlog by saving URLs with the Obsidian ReadItLater plugin and then using pan to convert the collection of markdown into an epub file.
The battery life is amazing. I've charged it once since getting on 3/27. I've read about 1500 pages (5 novels) since I got it (albeit I've stalled out in June by trying to finish a book I'm not too into).
It is a great compliment to a 10" tablet. Whereas a 7" reader tends to stay at home due to its size, the X4 gets tossed in my pocket and comes everywhere with me.
I love this thing and I use it a lot more than my kindle and my kobo (with koreader). I really like the form factor and the fact that goes out of sleep almost instantly and goes to sleep equally as fast. It seeps battery. It is perfect the way it is.
As someone who has resisted buying an e-reader for years because I "prefer physical books", I finally purchased a Kobo Clara BW and love it. Even though I usually only read one book at a time, having my whole library in a small form factor is really wonderful.
Hijacking … i have some random e-ink displays (from a bought product)… there seem to be 6 lines to the mcu (or 7, havent measured). Any 2026 tips on approaches to reverse engineer this to run on an arbitrary hobby mcu like esp32? Oh the mcu seems to be a WinnerMicro W100 Series MCU (arm m3)
Have the X4, the size is perfect - I always have it in my pocket and can read a view pages whenever I am waiting for something. Reduced my phone usage / doom scrolling nonsense with it. Best 50€ spent in a long time.
I’ve been looking at these for a while, hoping the custom firmwares for it will become more popular, as I was considering getting this for my six-year-old.
The disabled usb is certainly a bummer. I wonder how they disabled it though – is there a hardware difference?
To flash a new firmware on those devices you just need to place the firmware image of crosspoint on the memory card and then press UP+POWER to reboot and install the new firmware.
My device was the China edition that was locked (USB firmware upload disabled), the memory card method worked fast and easy.
I've been using it for about 6 months. Very, very good - especially paired with anna's archive.
IT IS VERY FRAGILE! The eink screen on my first broke while in my backpack. The company is generous, I bought a new one and they gave 35% off and included all accessories (reading light, case, extra protectors). Highly recommend.
I've bought a X3 and I loved it (with crosspoint). However, the screen broke after just a week, even if I used the official cover all the time. It's a cute gadget but it's too fragile for the intended use: its strength is the form factor, you want to bring it with yourself to read a page in any mobility setting, but its fragility is a critical issue.
Go for the X4. Neither supports USB file transfer, so having USB-C charging is convenient without additional things to worry about. Bigger screen is also better if you're a fast reader. The faster you read, the more your reading speed is limited by the page turn speed.
i bought a pocketbook era lite recently, and it's a bit too locked down for my tastes - though usable. i kinda just want a dumb appliance. actually, i want a linux appliance. this probably sounds very "not productized" to a PM, but 99% of what's on there i don't want: a book store, games, etc.
i wish there was just an SDK for building apps (i'll vibe code towards a great epub experience, i'm fine with that). and, i'm fine plugging it in via USB or even SCPing files over wifi. but, it sends my reading progress to a server every time i use it which is highly annoying and concerning. however, the form factor is sufficient.
i guess i was hoping it'd be more aligned with steam's direction with their steam machine.
I've looked at this device and I wonder how good the layout engine is. Screenshots never show text with any hyphenation going on which makes me wonder if it even supports hyphenation.
One of the images on the Amazon page for the reader has somebody holding one beside their laptop and if you look at the screen, it looks terrible. There are even words jammed together ("would be most suitable forthe job").
I love that it has physical buttons though. My reader is the Kindle Oasis and the buttons are one of my favorite features of the device. The Oasis layout engine and typography are both pretty good and I wonder if the X4 would end up feeling like a big downgrade.
The layout engine is limited. It does flow text quite well, but when I had mine (the screen broke a few months ago) I was working on adding more features to the rendering engine.
It's easy to write a HTML & CSS layout engine to support most of the epub spec, but hard to do it well on such a constrained chip. Even things like nested lists and inline code snippets are a challenge.
That must be why Amazon does a lot of pre-processing on their server. They know what device they are sending to and can tailor the file for that device.
Maybe expecting the X4 to look great is asking too much. It took Amazon years to get it right on Kindle. Hyphenation is a difficult task.
I love the X3, light enough I can carry it around without noticing it. Battery lasts forever. I don't feel the need for a backlight at all, I love how simple this is.
I know people favor the X4 for the usb-c, and I'm all for universal charging cables. But in my experience the usb port is often the first component to fail in something like this. And that seems super annoying to replace. The pogo pins on the other hand are unlikely to fail. And the cable is not proprietary, you can get compatible cables on Amazon/etc.
I've been eyeing the Xteink devices for a while now. They fit all the boxes - small, cheap, physical buttons - a basic reading utility. However, since there's no support for DRM, I'm worried either I won't be able to find books I want to read (what if I want the latest from my favourite author?), or I'll eventually run out.
Might be a tiny tinsy bit of purchase-anxiety as well - it'll be my first e-ink device after all, but what do I know...
Oh it comes with custom firmware? This is very interesting. I would love to be able to modify some UX and I am sorry, but I need to get the following out of my head. All the e-readers I have had have made it impossible to turn off features like:
1. Selection highlighting... I never use highlighting when reading fiction, but whenever I am not careful enough when turning a page, it'll go crazy with highlighting. Flashing screen, need to close the popup that has added the highlight, removing the highlight again etc.
2. Most of the time I don't want to click on a word to find out its meaning. It's sometimes useful, but I'd rather have it under menu to temporarily enable it. Same reason as before. My e-readers tend to prefer this often enough rather than taking the "next page" action.
3. Make "previous page" be small and not-under-my-finger. Ideally let me choose its position in a fairly precise way.
4. Easy access to accidental "scroll to page 900". I generally don't want it to happen and to be honest, I struggle to think of anybody who does. It can live in a single tiny faraway menu that is impossible to accidentally tap.
5. Swipe-left for previous page. It almost never happens when I want it to happen, so I'd rather turn it off.
In fact, I would love my e-book reader to have no gestures at all. Pretty please let me turn them off! All I want is a tiny button top-right or top-left corner for "open menu", a "previous page" in the other corner and otherwise "tap anywhere" is "next page".
Personal request to any e-book reader software engineers. Please save the position in the book to persistent storage on each page change or every few. At least if the e-reader has any chance of crashing at all, which has been the case with all the ones I have ever had. Yes, not all of them save it...
That's not to say that all the above things are universally bad UX. I think many of these are very useful, if reading non-fiction or having a different goal when reading such as learning a new language. It's just that they are less than brilliant if the goal is to read a book for entertainment in the most comfortable way possible with the fewest things going wrong by accidental taps.
The X4 doesn't have a touch screen, so you're safe on those points. The next iteration will do though, although I think you will be able to turn it off in the reader view.
It doesn't not come with custom firmware and xteink tried to block it citing hardware issues. Key word is tried and it's still very easy to install custom firmware.
It's also cool that it's chip is just an ESP32.
Or it can be a little bit bulkier and just be a dedicated ereader that is shaped like a phone case. Either way works.
In favor of the X3:
- Crisper text
- Whiter display
- Slightly better battery life
- Top-mounted power button (subjective)
In favor of the X4:
- Larger display
- Plain USB-C charging
- Slightly better custom firmware support
- Backward and forward button on the same side (subjective)
In a pinch, you can also connect it to a Bluetooth keyboard and use it as a development terminal. SSH terminal looks gorgeous on e-ink.

Is there a ebook format that isn't just build arround the concept of a webbrowser?
A format that only supported
- headings
- paragraphs
- emphasis (bold/italics)
- bullets
- inline images
is good enough. A simple container with a TOC pointing to text blocks/files within it that can be processed very cheaply.
Unfortunately, with something like epub, you lose all the simplicity because you want to support every single feature even if rarely used.
I have a Kindle and a Kobo. They are sturdy devices. But the X4 is the one that is a genuine e-reader. Would not get it as my one and only e-reader though as you tend to miss the size and backlight of the larger ones.
What would I want from future iterations?
- backlight even if it compromises on battery a bit
- a bit more DPI
Everything else is good enough.

only frontlight is possible.
They also have already announced the S4 that is basically the same device, a bit ticker with touch and backlight and running android.

The whole sticking-it-to-the-back-of-your-phone i find a bit useless, but mine came with two metal rings so that I can stick it to other places.
I have one ring on the dashboard of my car so the X4 can hang there until i need to use it. Good for trips with many stops.

FWIW, the X3 requires a pogo pin cable, while the X4 requires a standard USB-C.
Anybody got any recommendations?
Thanks!
I love it and use it every day.
a usbc is so easy to come by, you're never going to have to wait for amazon to deliver the cable you need to charge this one device you own.
Looking fwd to my reader soon!
i wish there was just an SDK for building apps (i'll vibe code towards a great epub experience, i'm fine with that). and, i'm fine plugging it in via USB or even SCPing files over wifi. but, it sends my reading progress to a server every time i use it which is highly annoying and concerning. however, the form factor is sufficient.
i guess i was hoping it'd be more aligned with steam's direction with their steam machine.
That seems to be what crosspoint-reader is: https://github.com/crosspoint-reader/crosspoint-reader
One of the images on the Amazon page for the reader has somebody holding one beside their laptop and if you look at the screen, it looks terrible. There are even words jammed together ("would be most suitable forthe job").
I love that it has physical buttons though. My reader is the Kindle Oasis and the buttons are one of my favorite features of the device. The Oasis layout engine and typography are both pretty good and I wonder if the X4 would end up feeling like a big downgrade.
It's easy to write a HTML & CSS layout engine to support most of the epub spec, but hard to do it well on such a constrained chip. Even things like nested lists and inline code snippets are a challenge.
Maybe expecting the X4 to look great is asking too much. It took Amazon years to get it right on Kindle. Hyphenation is a difficult task.
The custom firmware today is more than good enough, and the devices often sell for under $70.
And yet reading systems fail to do that.
I know people favor the X4 for the usb-c, and I'm all for universal charging cables. But in my experience the usb port is often the first component to fail in something like this. And that seems super annoying to replace. The pogo pins on the other hand are unlikely to fail. And the cable is not proprietary, you can get compatible cables on Amazon/etc.
I also built two quick hacks for it that people might like:

Might be a tiny tinsy bit of purchase-anxiety as well - it'll be my first e-ink device after all, but what do I know...
Personal request to any e-book reader software engineers. Please save the position in the book to persistent storage on each page change or every few. At least if the e-reader has any chance of crashing at all, which has been the case with all the ones I have ever had. Yes, not all of them save it...
That's not to say that all the above things are universally bad UX. I think many of these are very useful, if reading non-fiction or having a different goal when reading such as learning a new language. It's just that they are less than brilliant if the goal is to read a book for entertainment in the most comfortable way possible with the fewest things going wrong by accidental taps.
