XK Series – Full‑Size Typing, Foldable Design

The ProtoArc XK Series redefines portable keyboards. Unlike cramped travel keyboards, XK models fold into a compact tri‑fold shape but unfold to a true full‑size 105‑key layout with a dedicated numeric keypad. Whether you need a standard foldable keyboard (XK01), a backlit version for night work (XK01 Plus), a model with an integrated touchpad (XK01 TP), an ergonomic split foldable (XK03), or an ultra‑compact pocket keyboard (XK04) – the XK Series has a travel‑ready solution for every need.

Why the XK Series Stands Out

• Full‑Size Unfolded Layout – 105 keys including numeric keypad and function row (XK01, XK01 Plus, XK01 TP). No compromise on typing comfort.
• Tri‑Fold or Bi‑Fold Mechanism – Folds to pocket size (approx. 8.5 x 4.7 x 0.8 inches). Aluminum hinges tested for thousands of folds.
• Bluetooth Multi‑Device – Connect up to three devices simultaneously (laptop, tablet, phone). Switch with one button.
• Quiet Scissor‑Switch Keys – Silent, responsive typing perfect for coffee shops or open offices.
• USB‑C Rechargeable – Long standby (150 days or more), auto‑sleep when folded.
• Protective Case Included – PU leather or hard case with integrated tablet stand (most models).

Which XK Keyboard Fits Your Travel Style?

Choose XK01 for pure productivity, XK01 Plus for low‑light work, XK01 TP for mouse‑free navigation, XK03 for a split ergonomic layout, or XK04 for minimalists who want the smallest possible carry. All share the same durability and wireless freedom.
