What to buy for an Xteink X3, X4, or X4 Pro

eReader Magnetic Reading Light

The purpose-built one. Snaps to the X4's back magnet or clips to any book. Three colour temperatures, stepless 8–100% brightness, USB-C, 3–15h runtime.

X4 Magnetic Case

Official ultra-light back-snap case in six colours. Adds protection while keeping the magnetic mounting and slim profile. Sold direct from xteink.com; also on Amazon from the official XTEINK store.

Caution: Fits the X4 only, not the X4 Pro. The Pro is 3 mm shorter, drops the bottom-button cutout and relocates the back magnet, so X4 cases do not fit it.

X4 Pro Magnetic Case

Official back-snap case cut for the X4 Pro in six colours. Same ultra-light design as the X4 case but with the magnet moved up, the bottom-button cutout removed and a pogo-port opening, so X4 cases will not fit.

6 colours: Forest Green, Mint Green, Blossom Pink, Raspberry Red, Space Black, Cloud Grey

X3 Magnetic Case

The X3 version of the official magnetic back-snap case. Precise fit, six colours.

X4 Protective Case

14g semi-transparent polycarbonate shell: slim everyday knock protection that stays see-through.

X4 Pro Protective Case

Slim semi-transparent polycarbonate shell cut for the X4 Pro's shorter body and pogo port: cheap everyday knock protection that stays see-through.

2 colours: Mist White, Mist Gray

X4 Matte Screen Protector

Paper-feel matte film that cuts glare and adds a little writing texture to the X4 screen.

X4 Tempered Glass Screen Protector

Tempered-glass film for scratch and crack protection without the matte texture.

X3 Matte Screen Protector

Paper-feel matte film for the 3.7-inch X3 screen.

X3 Tempered Glass Screen Protector

Tempered-glass film for the X3.

eReader Magnetic Stick-On Ring

Official stick-on magnetic rings (3 black + 3 white) for phone-back carry on non-MagSafe phones.

Magnetic Pogo Pin Charging Cable (X3 & X4 Pro)

Spare magnetic pogo-pin charging cable. Both the X3 and the pogo-charging X4 Pro use it. Worth a backup, since it's easy to lose. The base X4 charges over plain USB-C and doesn't need it.

Magnetic Charging Adapter for X3 & X4 Pro

Official magnetic adapter that fits both the X3 and the X4 Pro pogo-pin port: plug in any USB-C cable and snap the magnetic end onto the reader to charge. A cheap drop-in backup for the easy-to-lose cable.

CoBak Magnetic Case for Xteink X4

Ultra-light PU-leather back-snap case for the X4. Keeps the magnetic mount and slim profile, with a soft anti-scratch liner inside. Sold in several colours (brown, black, red, sage green).

X4 Magnetic Case (AliExpress)

Third-party magnetic back-snap, several colours. Solid value if you want more colour options.

Shantime Leather Flip Wallet Case

Budget faux-leather flip wallet for the X4: magnetic closure, two to three card slots and a built-in kickstand. Sold in several styles (Oxford fabric, window, wallet, business).

UOGNADGD Colourful Case + 2× Tempered Glass

Colourful shockproof X4 cover bundled with two tempered-glass screen protectors: case plus screen protection in one cheap pack.

Leather Sleeve Case (Vegetable Tanned)

Handmade full-grain vegetable-tanned leather sleeve, individually cut for a snug fit. Develops a patina with use; made for both X3 and X4.

Handmade Book-Style Case (PETG)

Slim book-inspired case 3D-printed to order in PETG, styled like a traditional hardcover.

X4 Custom Reversible Slim Case

Snap-on slim shell that reverses: face-out with the screen exposed to read, then flip it to cover the screen in a bag. A longer bottom “chin” makes the page-turn buttons easier to reach, and the front can be 3D-printed with custom artwork (anime, logos, your own design).

Personalized Leather Pen Pouch Cover

Genuine-leather pouch a touch larger than the official case, adding a card slot and a pen holder. Personalisable with name engraving.

Handmade Wet-Mold Leather Sleeves (Vietnam)

Wet-moulded leather cases hand-shaped to exact X3/X4 dimensions by u/handmadefromvietnam. Each piece is made to order. Lead time varies; check the listing before buying.

Book Look Case for X4

Community-made hardcover-style case from Book Look Covers (Australia): magnetic lid, inner MagSafe ring to hold the X4, and a rear magnet for a reading light. Soft faux leather over a 3 mm MDF body. X3 and X4 Pro versions are still in development.

Caution: Fits the original X4 only. Confirm the live listing for the model you own; X3 and X4 Pro shells are not shipping yet.

DM Leather Studio Vertical Flip Case

Handmade vertical-flip leather case with an elastic closure and a magnet ring sewn under the leather, not glued on. Family-run Etsy shop. A horizontal folio with an inner sleeve is listed separately.

Personalized Magnetic Cover for X4 Pro

Third-party magnetic cover plus silicone case cut for the X4 Pro. One of the few Etsy shells owners are ordering now that official Pro colours keep selling out.

Caution: Community find, not an official Xteink case. Confirm the listing says X4 Pro before you pay: X4 shells do not fit the Pro.

PopSockets MagSafe Phone Grip

A MagSafe PopSockets grip doubles as an Xteink mount: the reader's magnet clicks onto the MagSafe base for dual-use carry.

Traveler's Notebook (Passport / Card Size)

An X3 with its magnetic cover slips into a passport-size Traveler's Notebook (or a card-size TN solo) for a minimal EDC carry setup.

LOCHBY Pocket Journal with Zipper

The larger LOCHBY fits the X4 in portrait with room for two pocket notebooks, a card slot and a pen. Doubles as a wallet or passport holder. On Amazon, or direct from lochby.com.

Pogo Pin → USB-C Adapter (X3 & X4 Pro)

A 2-pack of magnetic 4-pin adapters built for the pogo-pin port shared by the X3 and X4 Pro: plug any USB-C cable into the puck and snap its magnetic end onto the back to charge. A drop-in replacement for the easy-to-lose proprietary cable. Each has a lanyard loop and built-in over-charge / short-circuit protection.

Caution: Fits the 4-pin pogo port on the X3 and X4 Pro, not the USB-C base X4. Confirm the pin layout matches your unit before relying on it.

X3 LightCharge

Hand-built magnetic dock for the X3: a 2700K reading light on a fold-out arm, a 1600 mAh spare battery, and 4-pin pogo charging in one shell. Batch one pre-orders ship from early September. Files, parts kits, and assembled units are all on the same page.

Caution: X3 only. An X4 light is on the maker's roadmap, not for sale. Confirm your ship date at checkout; this is a one-person build.

X3 Magnetic Charging Dock

Desk dock that holds the X3 on pogo pins so it tops up when you set it down. Community-made, sold on Etsy.

Caution: Listed for the X3. The original X4 has no pogo port. Do not assume it fits the X4 Pro without checking the listing.

SanDisk 32GB Ultra microSD Card

Owners report the factory-bundled microSD can overheat and fail. The community fix is a name-brand SanDisk. This 32GB Ultra is a cheap, reliable swap that still holds thousands of e-books (cards up to 512GB are supported).

Full-Wrap Magnetic Case for X4/X3 (AliExpress)

Full-wrap, anti-collision magnetic cover with reinforced corners. One listing bundles both an X4 and an X3 fit (4.9★, 500+ sold).

Hoxutym Rechargeable Bookmark Book Light

Bookmark-clip reading light with three colour temperatures (warm / cool / mixed), five brightness steps, and a 360° gooseneck. Charges via USB-C in 30 minutes and runs up to 40 hours. At 0.06 lbs it barely adds weight to the reader.

ULANZI M10 Magnetic Fill Light

A MagSafe-style magnetic light on a flexible gooseneck. It snaps to the X4's back magnet and bends over the page as a reading light. Bi-colour 2500–4500K, five brightness steps, USB-C rechargeable. Doubles as a phone/video fill light.

LED Clip Reading Light for X3 & X4

Designed specifically for the Xteink X3 and X4. Clips to the top edge and casts warm LED light across the screen. Rechargeable via USB, 187 units sold.

Hogance Bluetooth Page Turner Clicker for X4

A 2-button Bluetooth 5.4 remote that flips pages forward or back without touching the screen, good for one-handed or hands-free reading. Rated for ~20 days on a charge at 2h/day; comes with a charging cable and wrist strap. Built for the X4 specifically, not the X3.

HanLinYue Free2 Bluetooth Page Turner (for X4)

A two-key Bluetooth clicker sold specifically for the X4. Four modes selected with a short press of the power button: page turn (up/down), page turn (left/right), music play/pause, and volume, plus swappable red (silent) and blue (clicky) switches and spare keycaps in the box. It's the clicker most often named in r/xteinkreader threads, and it's one of the page-turner devices the community CrossPoint BLE firmware fork recognizes by name in its built-in device list.

Caution: Needs Bluetooth pairing, so it works on the stock Xteink firmware out of the box. Mainline CrossPoint doesn't support Bluetooth yet. Only community forks like CrossPoint BLE add a page-turner back.

Folio-style TPU case with a built-in magnet-ring slot that keeps the ring in place, plus grooves for page-turn buttons.
