If you’re a fan of the XTEINK X4 or XTEINK X3, you may be wondering what other eInk microreaders are available. While there are previews of the XTEINK S4 look great (touchscreen, possibly a backlight) there are other new entrants appearing.

EINKING, EEGOGO, EEGOREAD – What’s it called again?
Yes, it’s confusing but let me explain. When the company first started teasing its device, they went by the name EINKING. After a few months and when they started sharing prototypes, they rebranded all their socials as EEGOGO. EEGOGO was also the name they used when they opened China pre-orders. In June though, some leaked production images and packaging have the name EEGOREAD. So which is it? Well China socials are still EEGOGO, so I’m sticking with that name for now but I suspect when the units officially ship in June, we’ll see the EEGO READ name reveal.

What are the EEGO P4 LITE AND A4 (formerly the EINKING)
One new microreader is from a company called EEGO A4. . EEGO have been teasing a device on Chinese social media for several months. The official model name for the EEGO is EEGO P4 Lite and EEGO A4. The EEGO is an updated take on the XTEINK X4

EEGO A4 and P4 Lite

EEGO have two devices, the EEGO A4 and the EEGO P4 Lite.

EEGO P4 Lite Specs (Open System)

touchscreen
238PPI
2Gb Memory / 32B Expandable
Front Light
microSD slot
WiFi + Bluetooth
USB C Charging

The P4 Lite supports 3rd party apps, I’m guessing it runs an older version of Android (like the XTEINK S4)

You can find a teaser video for the EEGO P4 Lite here.

EEGO A4 Specs (Close System)

The A4 is also now going by the name A4 Pro.

4″ touchscreen (768 x 528)
Size 69 x 105 x 7.7
Weight 96g
238PPI
2000mAh battery
dual core S3 processor (making it an ESP32 device)
claimed 8mb on board memory / 32Gb microSD expansion
real time clock
microSD slot
calendar
file support: TXT / EPUB / PDF / MOBI / JPG / BMP / PNG
front light
WiFi + Bluetooth + 3.5mm audio
vibration
NFC
USB C Charging

What’s in the EEGO A4 box?
Unboxing the EEGO A4, you will find

EEGO READ A4
32GB microSD card (preinstalled, later versions will ship with 16Gb)
Tray Eject Tool (the tray holds the microSD)
MagSafe Ring (for phones that don’t have MagSafe)
microSD Card Reader
USB C Charging Cable

This is much closer to the XTEINK X4, no 3rd party app support. So probably a custom OS given the ESP32 processor.

EEGO P4 and A4 Design

The EEGO devices have a touchscreen, but it also has touch buttons on the front (at least in current prototypes that ). EEGOGO have confirmed there will be a backlight. They’re much more rounded and remind me of Apple’s old magsafe battery in terms of look, albeit much much thinner.

An early preview of the EEGO deviceleaked to YouTube, I’ve embedded it at the end of this post.

Overall, the EEGO builds all everyone loves from the X4 but in a smaller better magsafe/back of phone design. The release date keeps shifting, if anything, we’ll have a serious challenger and alternative to the XTEINK S4.

EEGO P4 and A4 Pricing and Availability

In a teaser video on Chinese social media, EEGO promised an early bird price for the A4 of RMB199 ~ USD$30 and standard price RMB239 ~USD$35 which is very cheap; the P4 Lite pricing is listed as early birds RMB299 ~ USD$45 with a release price of RMB339 ~USD$50. Based on pricing, it would seem (oddly) that the P4 Lite is the ‘premium’ model despite the Lite name.

Will this put pressure on the XTEINK S4 price? Given pre-orders open before the S4 drops, I think this will be massively disrupting to XTEINK plans. Let’s see! Exciting times in the microreader space. FYI the XTEINK S4 was expected to release late April but has been delayed. Update! May 16th 2026, EEGO pre-order devices can now be claimed, so hoping to see shipments in June.

Based on factory production images, the initial run is about 40,000 devices across both models.

One thing that did happen is XTEINK and EEGO got into a fight on Chinese social media that resulted in both of them having to suspend preorder sales. You can read the summary of the XTEINK vs EEGO fight here. If you want the ;tldr, there are claims one side misrepresented the specs of their device and the ran campaigns to get people to complaint. End result, they both got suspended from being able to sell their pre-release devices.

When does the EEGOGO Ship?

I have pre-ordered both EEGO devices and they will (apparently) ship in June. They are no longer available for pre-order, it was just for a brief window in China.

Update! The EEGO A4 ships tomorrow (June 26th).

And here’s a video of the EEGO A4 price confirmation below. Enjoy!
