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, slim enough for a laptop sleeve
  • ✓ Aluminum internal hinges tested past 10,000 folds
  • ✓ Bluetooth 5.1 pairs three devices, one-button switching between them
  • ✓ Auto-sleep standby rated up to 150 days on a USB-C charge

Cons

  • ✗ 0.65in keycaps are slightly under standard desktop pitch
  • ✗ Two fold seams sit under the typing surface, unlike a rigid board
  • ✗ Scissor switches give shallow travel; not for mechanical-switch fans
  • ✗ Bluetooth only, so no 2.4GHz dongle or wired fallback

Manufacturer description

The ProtoArc XK01 is a full-size foldable Bluetooth keyboard built for people who refuse to give up a number pad just because they work from a backpack. You get all 105 keys, 0.65-inch keycaps, a dedicated function row, and navigation keys, so spreadsheet work and data entry feel the same on a hotel desk as they do at home. The tri-fold body collapses to 8.46 x 4.68 x 0.78 inches on internal aluminum hinges rated for over 10,000 folds, and the no-clip design means you unfold and type instead of fiddling with latches. Bluetooth 5.1 pairs three devices at once and swaps between your laptop…
