ProtoArc XK01 Full-Size Foldable Bluetooth Keyboard for Travel

Bottom line: The ProtoArc XK01 Full-Size Foldable Bluetooth Keyboard for Travel ($44.99 on Amazon as of 2026-10-06): Full 105-key layout with a real number pad, rare on folding travel keyboards; main trade-off: two fold seams sit under the typing surface, so it needs a flat rigid desk.

Pros & Cons

Pros

  • ✓ Full 105-key layout with a real number pad, rare on folding travel keyboards
  • ✓ Folds to 8.46 x 4.68 x 0.78 in, fits a laptop sleeve or tablet bag
  • ✓ 0.65in keycaps stay near desktop pitch, so touch typing transfers
  • ✓ Bluetooth 5.1 holds 3 devices, one-button swap between laptop, tablet, phone
  • ✓ Auto-sleep standby rated up to 150 days; recharges over USB-C

Cons

  • ✗ Scissor switches are quiet but shallow next to a mechanical travel board
  • ✗ F1-F12 requires the Fn + ESC layer instead of a dedicated toggle
  • ✗ No trackpad or pointing device, so you still pack a mouse for tablet work

Manufacturer description

The ProtoArc XK01 solves the travel-keyboard tradeoff most compact boards force on you: it keeps all 105 keys, including a full number pad, function row, and navigation cluster, then folds down to 8.46 x 4.68 x 0.78 inches so it slides into a laptop sleeve or tablet bag. The 0.65-inch keycaps stay close to desktop pitch, so your muscle memory carries over instead of resetting every time you leave your desk. Low-profile scissor switches keep the sound down in coffee shops, shared offices, and hotel rooms while still giving each keystroke a defined bottom-out. Bluetooth 5.1 pairs three devices…

Frequently Asked Questions

Does the ProtoArc XK01 have a real number pad?

Yes. It is a true full-size 105-key layout with a dedicated number pad, function row, and navigation keys, which is why it unfolds wider than most travel keyboards.

How small does it fold for travel?

Folded, it measures 8.46 x 4.68 x 0.78 inches. The tri-fold design uses internal aluminum hinges tested for over 10,000 folds and opens with no clips to unlatch.

Can I switch between my laptop, tablet, and phone?

Yes. Bluetooth 5.1 pairs up to three devices simultaneously and you switch between them with one button, so you can move from laptop to tablet to phone mid-task.

How is it charged and how long does a charge last?

It recharges over the included USB-C cable and uses auto-sleep standby rated up to 150 days, so it typically stays ready between trips. Runtime varies with use.

Is it quiet enough for an office or coffee shop?

The low-profile scissor switches are chosen for reduced typing noise in shared rooms and open offices. It is quieter than a mechanical board but not silent.
