Design & Build
Foldable design is the defining trait here. The ProtoArc XK04 folds to a pocket size with a PU leather cover, while the full-size ProtoArc XK01 unfolds to a 105-key layout complete with a number pad. The XK01 TP variant adds a multi-touch trackpad, and the XKM01 bundles a slim mouse plus a hard case. For a non-folding option, the Arteck ultra-slim keyboard is tablet-friendly and light, and the Samsers foldable model integrates a touchpad and phone holder.
Performance
Typing feel and connectivity are what matter most. The ProtoArc models shine with multi-device Bluetooth switching, letting you jump between a phone, tablet, and laptop with a keypress, and USB-C charging keeps them topped up quickly. The XK01’s full-size keys and number pad make it the closest to a real laptop keyboard for spreadsheet work, while the trackpad-equipped XK01 TP and Samsers models let you leave a mouse at home. The Arteck’s slim profile prioritizes portability and offers dependable, no-fuss pairing.
Pros & Cons
- Genuinely pocketable foldable designs for true portability.
- Multi-device Bluetooth switching across phone, tablet, and laptop.
- Full-size and number-pad options for serious typing.
- Built-in trackpads on select models replace a mouse.
- Folding seams can feel slightly less stable than solid boards.

Alternatives to Consider
If pocketability is everything, the ProtoArc XK04 folds smallest and slips into a coat pocket. For the most laptop-like typing, the full-size XK01 with its number pad is the productivity pick. Want to ditch the mouse entirely? The XK01 TP or Samsers model with an integrated trackpad is ideal, while the ProtoArc XKM01 combo adds a matching mouse and case. Tablet users who prefer a simple slim board should look at the Arteck.
Frequently Asked Questions
Can I connect a portable keyboard to multiple devices?
Yes. Models like the ProtoArc XK01 support three-device Bluetooth switching, letting you toggle between a phone, tablet, and laptop with a single keypress.
Are foldable keyboards comfortable to type on?
Modern foldables offer surprisingly comfortable travel and key spacing. Full-size models like the XK01 come closest to a laptop feel, though tiny keycaps need brief adjustment.
How are these keyboards charged?
Most use USB-C charging for fast top-ups and long battery life, so you can recharge with the same cable you use for your phone or tablet.
Do I need one with a trackpad?
A built-in trackpad is handy when you want to leave a mouse behind, especially for productivity on a tablet. If you already carry a mouse, a keyboard-only model saves space.
Verdict
A portable Bluetooth keyboard is one of the best upgrades for anyone who types on the go. The ProtoArc XK01 is our top pick for its full-size layout and number pad, the XK04 wins on pure pocketability, and the trackpad-equipped XK01 TP is best for mouse-free productivity. Choose the balance of size and features that fits your bag, and you will never dread mobile typing again.
