The Kit Bag
Every Xteink X4 & X3 accessory, in one list
10 official Xteink accessories that fit the X4 or X3 — the magnetic reading light, cases, screen protectors, stick-on rings and the X3 charging cable. Each has a photo, a price and a buy link straight to xteink.com, tagged with the model it fits. Owner-tested third-party picks will be added here once we've verified each one.
Start with the reading light — neither model has one built in, so it's the accessory almost everyone adds first.
Show for:
Reading light
1 itemNeither the X4 nor the X3 has a built-in front light, so a light is the one accessory almost every owner adds. The official magnetic light snaps flush onto the back magnet, with nothing clamping the screen. Avoid clip-on lights that grip the bare e-ink panel — that pressure can crack it.
Nothing in this category fits the selected model.

Buying notes
- Buy the light first — it’s the one accessory that changes how often you actually read.
- Attach lights via the magnet, not a hard clamp on the screen edge — clip pressure has cracked an X4 screen.
- X3 owners: grab a spare pogo-pin cable. It’s proprietary and easy to lose; the X4 just uses USB-C.
- Matte film adds a paper-like writing feel and kills glare; tempered glass protects harder but stays glossy.
- For phone-back carry, the stick-on rings matter more than the case.
- These are all official store items for now — owner-tested third-party picks come later, once verified.
