First Look at Viwoods AiPaper Reader, a Pocket-Sized E Ink Companion That Runs Full Android

Viwoods is making a splash in the crowded world of compact e-readers with the AiPaper Reader – a tiny device that squeezes the standard e-book experience into a phone-sized package while still delivering plenty of power. Measuring 159.4 by 80.3 by 6.7 millimeters and tipping the scales at just 138 grams, this reader slips easily into a jeans pocket alongside your phone. Hold it in your hand during your daily commute and the matte finish and rounded edges make it a joy to hold, with no unsightly indentations to deal with.

A 6.13-inch E Ink Carta 1300 panel produces incredibly clear text at 824 by 1648 pixels – which works out to 300 pixels per inch in black and white. The lines just seem to pop off the screen and a front light that can switch between cool blues for daytime and warm amber tones for nighttime reading is a clever touch. And as an added bonus, the panel is glare-free even in direct sunshine – perfect for reading on the go. Page turns are swift and easy, making it a breeze to zip through a novel on your commute.

If you’re after a color e-reader, the AiPaper Reader C is worth a look. This variant comes with Kaleido 3 technology which adds a whopping 4096 colours to the mix – though bear in mind the resolution drops to 150 ppi in colour mode and the screen does get a bit dimmer. Viwoods is pricing the monochrome model at $279 and the color version at $350 – though that latter is currently MIA as far as availability is concerned.


Powering the device is a 6nm octa-core processor which is paired with 4GB of RAM and 128GB of storage – a not bad spec for an e-reader. What’s more, it’s one of the first e-readers on the market to run Android 16 – which also gives you access to the Google Play store. Installing apps such as Kindle, Kobo or Libby is a doddle, and the system promises long-term compatibility. For those who need to be on the go, a dual-band WiFi connection lets you download your e-books while at home, and there’s even a SIM card slot for data-only 4G connectivity – though bear in mind you won’t be making any phone calls.

Battery life is extended by a 2,580mAh cell working in conjunction with the E Ink efficiency. If you’re a casual reader, you can get away with days between charges via USB-C. Bluetooth 5.0 lets you connect up your headphones for audiobooks, and the built-in speaker handles the odd bit of listening. When you need to switch between portrait and landscape modes, a G-sensor will automatically flip the page for you.


On the side of the reader there’s a little button that lets you ask questions. Tap it, and speak or type in your question, and you’ll get a response from large language models such as ChatGPT, Gemini or DeepSeek – all alongside the content on your screen. You can get help with summarizing chapters, translating paragraphs or even save snippets to your own personal knowledge base – all without ever leaving the page. The UI keeps the answers in the background, always keeping the page itself front and center.



Refresh modes provide fast and ultra-fast modes for a seamless app navigation experience. Third-party apps are useful for static activities, but let’s be honest: it’s still an e-reader at heart, and the feared E Ink ghosting from time to time serves as a good reminder of that. The Onyx Boox Palma 2 may have a comparable size to the Viwoods, but this one – better than any of its competitors – stands out for the updated Android and built-in cellular connectivity that you get straight away.



Kindle aficionados tend to praise the reader’s simplicity – and in terms of that locked-down feel, it’s a definite winner – but it also opens up opportunities for others who prefer a little more flexibility. Want to install a news app, surf a little, or simply stick to your books? It’s up to you. For $279, the monochrome AiPaper reader is a really capable solution that allows you to live in the current day without overwhelming it.
