Manufacturer description

The ProtoArc XK01 solves the travel-keyboard trade-off most compact boards force on you: it folds down to 8.46 x 4.68 x 0.78 inches, then opens into a genuine 105-key layout with a full number pad, function row, and navigation cluster. The 0.65-inch keycaps keep your desktop muscle memory intact, so spreadsheet work and data entry don't slow down on the road. Internal aluminum hinges are tested for 10,000+ folds, and the no-clip design means you unfold and start typing without fussing with latches. Bluetooth 5.1 pairs three devices at once and swaps between your laptop, tablet, and phone…

SpecPicks Verdict

SpecPicks scored ProtoArc XK01 Full-Size Foldable Bluetooth Keyboard for Travel using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. ProtoArc's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for gaming peripherals of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Does the ProtoArc XK01 have a real number pad?

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

How many devices can it connect to at once?

Three. Bluetooth 5.1 holds up to three paired devices, and one button switches among them, so you can move between a laptop, tablet, and phone without re-pairing.

How small does it fold for travel?

Folded, it measures 8.46 x 4.68 x 0.78 inches. The tri-fold hinges are aluminum and tested for more than 10,000 fold cycles.

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

It recharges via the included USB-C cable. ProtoArc rates auto-sleep standby at up to 150 days, though active typing time depends on your usage.

Is it quiet enough for an office or coffee shop?

It uses low-profile scissor switches chosen to cut typing noise in shared spaces. It is quieter than a mechanical keyboard, not silent.
