Bottom line
The ProtoArc XK01 Plus is a practical travel keyboard for people who want a number pad and familiar full-size layout without carrying a conventional desktop board. Its folding design, backlighting, and three-device Bluetooth switching are useful, but frequent typists should expect compromises in rigidity and key feel compared with a solid keyboard.
Buy this if
- You enter numbers, work in spreadsheets, or use business software that benefits from a dedicated number pad.
- You travel with a laptop or tablet but dislike cramped compact keyboards.
- You move among as many as three Bluetooth devices and want a keyboard that can switch between them.
- You work in dim rooms and need illuminated keys rather than relying on ambient light.
- You want USB-C charging instead of regularly replacing disposable batteries.
Skip if
- You primarily type at one desk, where a rigid keyboard will usually feel steadier and offer fewer mechanical compromises.
- You need a mechanical switch feel, extensive remapping, or gaming-oriented performance.
- You want the smallest possible travel keyboard; the full-size layout and number pad still require meaningful bag and desk space when opened.
- You require guaranteed wired operation. The listing emphasizes Bluetooth and USB-C charging, so verify wired-mode support on Amazon before ordering.
Layout, noise, and how it connects
Input gear is chosen on three things spec sheets bury: how loud it is around other people, how much desk it eats, and how cleanly it pairs with the machines you actually use.
What this listing states
- Bluetooth — listedNo dongle to lose and no USB port used — the better choice on a port-starved laptop.
- Rechargeable battery — listedOne less battery to buy, one more cable in the rotation. Replaceable AAs often run for months.
- Mechanical switches — listedBetter feel and durability, and typically louder unless the listing specifies silent switches.
- Number pad — listedEssential for spreadsheet work, and the single biggest thing costing you desk width.
- 2.4GHz receiver — not listedThe most reliable low-latency option, at the cost of one USB-A port.
- Quiet switches — not listedThe difference between usable and unbearable in a shared room or on a video call.
- Ergonomic shape — not listedWorth considering if you already feel wrist or forearm strain by the end of a working day.
Match it to your desk and your day
- On calls often? Avoid clicky switches entirely — look for silent linear switches or a quality membrane board.
- Desk narrower than about four feet (120cm), or you use a wide mouse sweep? A 75% or tenkeyless layout buys back real room.
- Count your free USB-A ports before choosing a receiver model; modern thin laptops often have none.
- Switching between a laptop and a tablet all day? Multi-device pairing saves more time than any switch type.
- If you type all day, key height and wrist angle will matter more in a month than switch feel does today.

Performance & everyday use
The XK01 Plus addresses a real weakness of many portable keyboards: reduced layouts. Its listed 105-key arrangement preserves a number pad and common navigation controls, making it better suited to spreadsheets, invoices, data entry, and remote office work than a minimalist travel board. The tradeoff is that portability comes from folding rather than removing keys.
Bluetooth 5.1 connectivity and three-device switching should be useful for a laptop-tablet-phone setup. Switching is more convenient than pairing again each time, although Bluetooth keyboards can take a moment to reconnect after sleeping. Buyers who need instant wake behavior or interference-free input may still prefer a wired model.
Backlighting improves key visibility during evening work and flights, but it will consume battery faster than typing with the lights off. ProtoArc does not provide enough verified usage detail here to promise a particular runtime, so charging frequency will depend on brightness, work habits, and sleep settings. Check the current Amazon listing for battery and lighting-mode claims.
This is an office and travel keyboard, not an obvious choice for competitive gaming. Its strongest case is layout convenience and device flexibility rather than ultra-low latency or highly customizable controls.
Build, comfort & setup
The gray folding chassis is easier to pack than a fixed full-size keyboard, but any hinged design is less uniformly rigid than a conventional one-piece frame. It should work best on a desk, tray table, or other flat surface; typing directly on a lap may allow the sections to shift or flex.
The relatively broad layout should feel less crowded than many portable alternatives, though hinge placement and low-profile keys may require an adjustment period. Long-session comfort remains personal, especially for buyers accustomed to sculpted desktop boards or mechanical switches.
Setup should be straightforward: charge by USB-C, place the keyboard in pairing mode, and connect it through the device's Bluetooth menu. Verify operating-system compatibility and shortcut labeling on Amazon if you depend on platform-specific function keys.
Value & alternatives
The XK01 Plus offers a compelling feature combination for mobile office work: full-size input, a number pad, illumination, rechargeable power, and multi-device pairing. Check Amazon for the current price and compare it with both compact folding keyboards and standard wireless desktop models.
A cheaper compact keyboard may be the better value if you rarely enter numbers. A rigid wireless keyboard is preferable if portability is secondary, while a premium mechanical model makes more sense for buyers prioritizing switch feel, repairability, or deep customization.
Verdict
The ProtoArc XK01 Plus is worth considering for traveling professionals, night workers, and spreadsheet-heavy users who refuse to give up a number pad. It is less appealing as a permanent desktop keyboard, but its complete layout and folding design solve a specific portability problem better than most stripped-down travel boards.
