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.
> 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.
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.
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
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.
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.
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.
I love my X3. I glued its magnetic folio to the back of my Apple Wallet so that it's always with me. I've read The Odyssey and several other shorter books on it and have yet to recharge it.
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.
I have one of these and they're great. If you get one though, you really do need to convert to XTC for not terribly jagged glyphs -- https://x4converter.rho.sh/
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.
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.
> 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.
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.
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.
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..
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...
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.
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.
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 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.
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 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.
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 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.
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)
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.
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?

Does your reading position sync up between the two devices?

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.
There are rumors they will release a V2 Pro version with touch and backlight in the second half of this year.
They also have already announced the S4 that is basically the same device, a bit ticker with touch and backlight and running android.
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.
All of this. It's a solid device. I like it. It won't replace my Kobo, but it has it's place in my tech lineup.
Will buy the next one if it has a light.
I love my X3. I glued its magnetic folio to the back of my Apple Wallet so that it's always with me. I've read The Odyssey and several other shorter books on it and have yet to recharge it.

https://crosspointsync.com/
Thank you. I'm not the biggest fan of the Crosspoint web interface, so I'll definitely give this a try.
I've been eyeing the Xteink Reader but cannot decide between the X4 (4.7" diag) and X3 (3.7" diag).
FWIW, the X3 requires a pogo pin cable, while the X4 requires a standard USB-C.
Anybody got any recommendations?
Thanks!
I picked the X4 over X3 because the usb-c is convenient for charging (which you barely need to do)
I love it and use it every day.
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.
The X4. I always have a USB-C cable handy; so, i can charge it in the bedroom, at y desk, etc.
CrossPoint 1.4.0 came out 2 hours ago:
https://github.com/crosspoint-reader/crosspoint-reader/relea...
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.
epub is overkill for a vast majority of books.
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.
HTML and CSS is enough for 99% percent of epubs, and that's the only subset of epub standards that Crosspoint tries to support
Isn't HTML and CSS already a huge surface to support, unless you are happy with a subset?
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.
As a crazy person with both, I have mixed feelings between them.
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)
link the custom firmware!

Crosspoint is very popular and very easy to flash onto the device.
Locking and preventing flashing of firmware only happened in China.
This page mentions international models, but seems it's still possible to flash them in any case
https://crosspointreader.com/#unlock-tool

The no USB flashing doesn't appear to be the case if you get it straight from OEM. It is a bit pricier than amazon.

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 love my X4. I throw it in my backpack or pocket when I take the dog to the park and read a few pages when we sit in the shade.
been using on the back of my phone for a few months, my most satisfying hardware purchase in a long time
what phone does it fit on? I have the X3 coming today for this very reason. The x4 is just too big and the magnets misplaced to fit on any phone I own
iPhone pro max, fits nicely even with a cover, i also have a x3 but slightly prefer the bigger screen of x4’s but portability on is the read deal
Just seeing it act as a trigger to read for me, especially when book cover as standby background
