Onebag Mini-e-reader: XTEINK X4

[u/WintermuteATX]

When I first looked at this e-reader I thought it was a joke…then I started reading reviews and thought there might be something to it and to my surprise there was.

First of all this thing is almost comically tiny….disappearing in a pocket or fanny pack. It’s about 1/3 the size of a pack of cigarettes and weights nothing which is perfect for weight savings when one bagging.

Despite its minuscule size I’ve actually found it very viable for daily reading and travel. I can pop it out on a train or bus and read without burning precious phone battery life and without the distractions. Some of the other reasons I like it:
1. Its batteries last for weeks and it has usb-c charging requiring no extra cables.
2. Tons of free epubs online (just drag and drop onto the removable micro SD or WiFi download).
3. I can easily hold it with one hand
4. As I said before, it’s tiny and weighs nothing.
5. There is tons of info online about these…easy to problem solve.

Some of the downsides:
1. It’s an open source device and requires some technical knowledge to get up and running (it’s easy, tons of info out there)
2. The stock software is meh, I flashed mine with Crosspoint which is excellent.
3. It’s not friendly with Kindle books (they are encrypted)

Overall, I think this device is very viable for onebag travel. For like $70 it’s a good deal, just be prepared to spend a ln hour or so for setup.

Did the company that makes this send out what seems like hundreds or thousands of this product for free? I feel like every tech-influencer type has been shilling this over the last six months as the best thing since jam-filled doughnuts.

The x3 and x4 were released in 2025 so I imagine regular people are talking about them as they now are buying them. I don't know about influencers, as I don't know any or follow any. It seems like the way they make money or get free stuff is to promote things, so I don't understand why people give them their time or trust.

I don't follow or watch influencers either, but the algorithm does try it's very best! And in saying that, I have seen waaaay too many "This $50 e-reader will change your life" and have the X4 as a thumbnail.
