ProtoArc XKM01: The Fold-in-Half Keyboard That Went Full-Size
The travel board Instagram keeps sending you. A 105-key board that folds like a taco, ships with a mouse, and is the reason “foldable keyboard” became a search term again.
InteliToys exists for products that make a nerd stop mid-scroll. The ProtoArc XKM01 is the platonic form of that: a full-size 105-key keyboard that folds in half, drops into a hard case, and still has a number pad. It is the folding keyboard people mean when they say “the one from Instagram.”
The trick is not that it folds. Plenty of silicone travel boards fold. The trick is that once you open the hinge, it feels like a real keyboard: scissor switches, a proper layout, Bluetooth plus 2.4 GHz, and a matching slim mouse in the same clamshell. Digital nomads, hotel-room editors, and anyone who refuses to type on a laptop deck for six hours have turned it into a default recommendation.
What to actually check before you buy: hinge slop after a month of daily folds, whether the right-side cluster lands under your hand the same way every time, and how the board pairs to a phone, a tablet, and a Linux box without becoming a Bluetooth archaeology project. The XKM01 is at its best as a three-device traveler, not as a permanent desktop replacement.
If you care about split ergonomics more than numpad cosplay, look at the Targus AKF003 or Keychron B11 Pro instead. If you want the “as seen on Instagram” object that folds in half and still looks like office equipment, this is the one the algorithm already picked.
SEO note for humans, not crawlers: foldable keyboard, tri-fold Bluetooth keyboard, travel keyboard with trackpad alternatives, ProtoArc XKM01 review, and “keyboard that folds in half” all describe the same itch. InteliToys covers the itch, then the hinge, then whether it survives a backpack.
