ProtoArc XK01 foldable keyboard review: this is a portable typing setup aimed at people who want laptop-like control from a phone, tablet, or compact travel workstation.
The built-in trackpad, 88-key layout, and three-device switching make the appeal clear.
XK01 Foldable Keyboard Review Summary
The ProtoArc XK01 is a strong fit if you want to reduce the number of accessories you carry without giving up mouse-style navigation.
Its core value is simple: a foldable Bluetooth keyboard with a built-in multi-touch trackpad, full shortcut row, and support for switching between three devices.
That combination makes it especially relevant for travelers, remote workers, students, and anyone who uses a tablet or phone for longer sessions of writing, messaging, or light productivity.
It is not trying to be a desktop keyboard replacement. It is trying to be a practical mobile input tool that covers the main tasks most people actually do away from a full workstation.

Key Features and Specifications of XK01 Foldable Keyboard
The most important feature is the integrated multi-touch trackpad.
For tablet and phone users, that matters more than a simple folding mechanism because it lets the keyboard handle both typing and pointer control.
The listing also highlights gesture support, which should make navigation feel closer to a small laptop than to a bare keyboard.
The XK01 uses an 88-key layout with 0.65 in keycaps and a full shortcut row.
That is the kind of detail that separates it from ultra-minimal travel keyboards.
The layout should be more usable for frequent typing, shortcuts, and general work sessions, even though a foldable design still means some adaptation is inevitable.
Other useful listing details:
- Tri-fold all-in-one design
- Built-in touchpad with multi-touch support
- Phone stand included
- PU leather carrying pouch included
- Bluetooth 5.1 connectivity
- Three-device switching
- USB-C charging
- 300mAh battery
- Up to 120 days standby
- Auto-sleep after 60 minutes of inactivity
The product positioning is clear: this is a mobile productivity keyboard first, not a gaming accessory or a full-size office keyboard.
The folding format and travel bundle support that identity.
Pros and Cons of XK01 Foldable Keyboard
Pros
- Built-in trackpad removes the need to pack a separate mouse.
- Three-device Bluetooth switching is useful for mixed-device workflows.
- 88 keys and a shortcut row make it more capable than many tiny travel keyboards.
- Foldable design, stand, and pouch make it easy to carry.
- USB-C charging is convenient and modern.
Cons
- Foldable keyboards still involve a compromise versus a rigid full-size keyboard.
- The trackpad is helpful, but touchpad-first workflows are not for everyone.
- Best suited to mobile use, so desktop buyers may want a more traditional setup.
- The tri-fold form factor may not appeal to people who prefer a single solid typing surface.
The biggest strength is that the product is solving a real portability problem instead of adding gimmicks.
The biggest limitation is also obvious: any foldable keyboard asks you to trade some stability and spaciousness for compactness.
Who Should Buy XK01 Foldable Keyboard?
Buyers who will get the most from this model are people who regularly type on a phone or tablet and want fewer accessories to manage.
If your workflow includes messaging, notes, email, documents, or remote admin work across multiple devices, the XK01 is designed around that use case.
It also makes sense for travelers who want one compact input device that can live in a bag without taking much space.
The included stand and pouch reinforce that role.
If you value a cleaner carry kit and want keyboard-plus-trackpad control, this is a sensible fit.
People who should probably skip it are those who mostly work at a desk and never leave a larger monitor-and-mouse setup.
If you dislike compact keyboards, do not need touchpad control, or want a device that feels more like a full desktop keyboard, this is likely the wrong category.
Mobile Productivity and Control
Trackpad-First Convenience
The trackpad is what makes the XK01 more interesting than a generic foldable keyboard.
It gives tablet and phone users a way to move around interfaces without constantly reaching for a screen or carrying a separate mouse.
Switching Between Devices
Three-device Bluetooth switching is a meaningful productivity feature rather than a marketing line.
For people who bounce between a phone, a tablet, and a laptop, staying connected without repeated pairing is a real quality-of-life improvement.
Typing on the Go
The 88-key layout and full shortcut row suggest a serious attempt to preserve function in a smaller package.
That should matter to buyers who do more than casual note-taking and want a travel keyboard that still feels capable.
Battery and Travel Use
The 300mAh battery, USB-C charging, auto-sleep, and claimed standby duration all point to low-maintenance travel use.
The useful question is not whether it can sit in a drawer forever, but whether it can stay ready when you actually need it on the road.
Alternatives to XK01 Foldable Keyboard
If you want a different foldable or compact mobile keyboard, the most obvious alternatives are other travel-first keyboard lines with strong device switching or compact layouts:
- Logitech K380 for a simple compact Bluetooth keyboard without a built-in trackpad.
- Logitech Keys-To-Go for a thinner travel keyboard approach.
- ProtoArc folding keyboard if you want to stay within the same brand family and compare variants.
- iClever folding keyboard if you want to compare another travel-focused foldable line.
The main choice point is whether you want an integrated touchpad.
If yes, the XK01’s category narrows quickly.
If no, you may prefer a simpler compact keyboard that puts all of its space into typing instead of pointer control.
Is XK01 Foldable Keyboard Worth It?
Yes, if your priority is portable productivity and you want one device that handles both typing and pointer control.
The ProtoArc XK01’s built-in trackpad, three-device switching, 88-key layout, and travel-friendly accessories make it a practical pick for mobile workers.
It is less compelling if you mainly sit at a desk or want the feel of a rigid full-size keyboard.
But for tablet users, phone-first workflows, and travelers who want to lighten their bag, the XK01 looks worth considering because it solves a specific problem with a focused feature set.
