The ProtoArc XK01 is a tri-fold Bluetooth keyboard with a dedicated numpad, scissor-switch keys, multi-device (3-device) pairing and an optional touchpad variant — offering true portability (8 x 5 x 1 in, ~10.5 oz) and long battery life for mobile workflows. It’s a strong travel/productivity option thanks to full-size notebook-style key spacing and a built-in numpad, but expect no key backlighting, some hinge durability and occasional Mac key compatibility quirks.
For travelers and mobile professionals who want a near-full, tri-fold Bluetooth keyboard (numpad, multi-device pairing); avoid if you need backlighting or demand hinge-grade durability.
