ProtoArc XK01 Foldable Keyboard with Touchpad review is for buyers who want a real travel keyboard, not just a tiny emergency accessory.
It combines an 88-key layout, a built-in multi-touch trackpad, and 3-device Bluetooth switching in a foldable body.
XK01 Foldable Keyboard Review Summary
The ProtoArc XK01 is a good fit if you use a phone or tablet like a small work machine and want fewer separate accessories to carry.
Its strongest appeal is the way it tries to replace both a keyboard and mouse in one portable setup, while still keeping a fuller typing layout than many ultra-compact foldables.
Verdict: worth a look for mobile productivity users who value convenience, shortcut access, and multi-device switching more than desktop-level typing comfort.

Key Features and Specifications of XK01 Foldable Keyboard
The product data points to a clear use case: portable typing with fewer compromises than the smallest foldable keyboards.
ProtoArc describes the XK01 as a tri-fold all-in-one travel tool with a built-in touchpad, phone stand, and PU leather carrying pouch.
The core hardware is built around an 88-key layout with 0.65 in keycaps and a full shortcut row.
That matters because many foldable keyboards shrink too aggressively, leaving you with cramped keys and awkward function access.
Here, the layout is still compact, but it is closer to a practical working keyboard than a throwaway travel board.
Key supported details:
- Built-in multi-touch trackpad with gesture support
- Tri-fold portable design
- 88-key layout with full shortcut row
- 0.65 in keycaps
- 3-device Bluetooth 5.1 switching
- USB-C charging
- 300mAh battery
- Up to 120 days standby claim
- Smart sleep after 60 minutes of inactivity
- Folds to power off for travel readiness
The 3-device Bluetooth switching is one of the clearest productivity benefits.
If you move between a phone, tablet, and laptop, being able to swap connections without re-pairing is a real convenience gain.
The trackpad also changes the product category a bit: this is not just a keyboard, but a mobile input surface meant to reduce how much gear you carry.
Pros and Cons of XK01 Foldable Keyboard
Pros
- All-in-one convenience: keyboard and touchpad in one device reduces clutter.
- More usable than tiny travel boards: the 88-key layout is a meaningful advantage.
- Good for multi-device setups: 3-device switching is ideal for mixed workflows.
- Travel-friendly extras: the pouch, phone stand, and folding design support mobility.
- USB-C charging: easier to power than older proprietary designs.
Cons
- Still a compromise: a foldable keyboard will not feel identical to a full-size desktop setup.
- Trackpad-first expectations can be risky: built-in pointer control is convenient, but users who want a premium laptop trackpad may want something more substantial.
- Best for lighter work: the specs fit mobile productivity more than long daily typing sessions.
- Layout tradeoff remains: 88 keys is generous for a foldable design, but not the same as a full desktop keyboard.
Who Should Buy XK01 Foldable Keyboard?
This is a strong fit for people who regularly work from a tablet, phone, or secondary device and want a compact way to type and navigate without carrying a separate mouse.
It also makes sense for travelers, digital nomads, and hybrid workers who want a more complete mobile workstation than a basic Bluetooth keyboard can provide.
It is especially appealing if you switch between devices often.
The 3-device Bluetooth 5.1 feature removes friction, and that can matter more in practice than raw spec-sheet prestige.
You should probably skip it if you want the feel of a full-size desktop keyboard, if your work involves long typing sessions every day, or if you already rely on a high-end mouse and do not care about integrated pointer control.
The XPK-style convenience only pays off if you actually need the portability.
If your main goal is to keep your bag light while still having something workable for emails, notes, document edits, and remote control tasks, the XK01 fits that use case well.
How the XK01 Handles Mobile Productivity
Typing on a Compact Foldable Layout
The 88-key layout is the most important reason this product stands out.
It signals a more serious typing experience than the smallest travel keyboards, and the full shortcut row should help users who rely on quick commands instead of menu hunting.
Trackpad and Pointer Workflow
The integrated multi-touch trackpad is not just a bonus feature; it is what makes the XK01 feel like a mobile workstation instead of a keyboard accessory.
For tablet and phone users especially, having built-in gesture support can streamline basic navigation without needing another device in hand.
Multi-Device Switching in Practice
Bluetooth 5.1 with 3-device switching is a practical productivity feature, not a spec to ignore.
If your workflow jumps between a laptop, tablet, and phone, this makes the keyboard easier to keep in rotation.
It is one of the clearest reasons to choose this model over a simpler foldable board.
Battery and Travel Readiness
The 300mAh battery, USB-C charging, and standby claims suggest a product designed around occasional charging and long idle periods.
The auto-sleep and fold-to-power-off behavior also make sense for travel, because they reduce the chance of wasting battery when the keyboard is packed away.
Alternatives to XK01 Foldable Keyboard
If you want similar portable input but prefer a different design, these are the most relevant places to look:
- ProtoArc foldable keyboard alternatives
- iClever foldable keyboard
- Jelly Comb foldable keyboard
- OMOTON Bluetooth keyboard
The main comparison point is whether you want an integrated trackpad or just a simpler portable keyboard.
If you do not need pointer control, a lighter Bluetooth keyboard can be enough.
If you do, this ProtoArc model is competing against other foldables that try to pack in mouse-like navigation as well.
Is XK01 Foldable Keyboard Worth It?
For the right buyer, yes.
The ProtoArc XK01 Foldable Keyboard with Touchpad is worth it if you want a compact, carry-friendly keyboard that also handles pointer input and multi-device switching.
Its value is strongest when you use tablets or phones as real work tools and want to cut down on what you carry.
The 88-key layout, shortcut row, built-in trackpad, and 3-device Bluetooth support all point in the same direction: this is a productivity-first travel keyboard.
If you want the most natural typing feel possible, this kind of product still involves tradeoffs.
But if your priority is a practical mobile setup with fewer accessories, the XK01 is a sensible choice.
