BOOX Note Air 10.3" 4C 2025
The 10.3-inch Kaleido 3 color E Ink display renders 4,096 hues at 300 ppi in black-and-white, driven by an octa-core BSR chip for minimal ghosting. Weighing 420g with a slim 5.8mm aluminum unibody, it adds a microSD slot, fingerprint reader, Android 13, and a stylus with 4,096 pressure levels on flat cover-lens glass. Best for illustrators and note-takers needing an eye-friendly color ePaper canvas, though pure readers may prefer the sharper 300 ppi B&W mode over the 150 ppi color layer.
Snapshot
The 30-Second Version
The Note Air 4C is a magnificent color e-ink notebook that'll make you fall in love with writing on a screen, right up until the battery dies three hours into a study session. Fantastic device, terrible endurance.
Pros & Cons
Pros
- The note-taking feels like real paper—fast, accurate, and addictive 85th
- Color screen makes highlighting notes and reading comics a completely different experience 81st
- Android 13 means you can install apps like Kindle, OneNote, or even Twitter 76th
- Build quality is solid—thin, light, and the fingerprint reader is a nice touch 66th
Cons
- Battery life is atrocious; you'll be charging it daily with light use
- Pen nibs wear down fast and replacements are impossible to find
- Screen clarity takes a hit versus monochrome e-ink—text looks slightly less crisp
- 64GB storage is stingy, though the microSD slot partly saves it

The proof
Performance
What surprised us most is how smooth the note-taking digitizer feels. Seriously, writing on this thing is a joy—it's fast, accurate, and that slight toothy drag from the stylus makes it feel like paper. Android apps run reasonably well too, which isn't always a given on e-ink, and the octa-core chip keeps navigation snappy enough. On the flip side, the 3700mAh battery is a total letdown. With the front light on, you'll be charging it far more often than any e-reader should need. It's dead last in our battery rankings, and that's saying something for a device that's supposed to sip power.

vs Competition
Stack this against an iPad Pro M5 or a Samsung Galaxy Tab S11 Ultra, and you'll scratch your head at first. Those slates run circles around the Note Air 4C for video, gaming, and multitasking. But when it comes to eye comfort and paper-like writing, the Boox is in a different league. If you buy a tablet to watch Netflix and scroll Twitter, get the iPad. If you want a distraction-free note-taking machine with a color screen, the Boox wins. It's not really competing with those giants—it's playing a completely different game.

Price
Value & Pricing
Prices for the Note Air 4C are all over the map, ranging from $500 to over $1,200 depending on the vendor. That's a huge spread, so do your homework—don't pay more than $600 for this thing. At the right price, it's a solid buy for the niche crowd who needs a color e-ink notebook. But for anyone else, a basic Kindle or an iPad is a smarter way to spend that cash.

Overview
The BOOX Note Air 4C is one of those devices that makes perfect sense the moment you use it for the right task, and totally confusing when you try to treat it like a normal tablet. It's a color e-ink digital notebook that runs Android 13, so you can scribble notes in 4,096 colors and actually read comic books without squinting at grayscale. But if you buy this hoping to replace your iPad, you're going to be really disappointed. The one thing to know: the writing experience is genuinely excellent, the color screen is a game-changer for note-takers and artists, and the battery life is a joke. Like, a bad joke.
Common Questions
Q: Can I watch YouTube or play games on this?
Technically, yes—it runs Android and the screen has a 'fast mode' for video. But it's a choppy, ghost-filled mess, and you'll hate it. This is for reading, writing, and static content, not entertainment.
Q: How long does the battery actually last?
With the front light off and just note-taking, maybe two days. Use the light heavily and you'll be charging it every night. It's the biggest weakness of this tablet, no sugar-coating it.
Q: Does the stylus need charging and can I use a different pen?
Nope, it's a passive EMR stylus, so no battery needed—awesome for always-ready writing. You can use other Wacom EMR pens, which is good because the included one's nibs are a pain. Grab a Staedtler Noris digital if you can.
Who Should Skip This
If you're looking for a general-purpose tablet for media, gaming, or long battery life, the Note Air 4C isn't it. Go get an iPad 10th gen or a Samsung Galaxy Tab S9 FE instead. Heavy readers who don't need color should also think twice—a Kindle Scribe or reMarkable 2 will give you a sharper screen and better battery for less money.
Verdict
Buy the BOOX Note Air 4C if you're a student, artist, or note-taking obsessive who's been waiting for a color e-ink screen that actually works. The note-taking is top-tier, and seeing your work in color is legitimately useful. Just know that you'll be tethered to a charger and annoyed by nib replacements. For everyone else, this isn't the tablet you're looking for—go grab an iPad Air or a reMarkable 2 instead.
