Nillkin Cube Pocket Keyboard Review: clever travel tool that needs a lock for real life

The trip that sold me on the idea, then reality checked it

I took the Nillkin Cube Pocket Keyboard on vacation because it promised the travel dream. Tiny footprint, unfolds into a real keyboard, built-in touchpad so I would not need a mouse. That checks every box for café hopping, tray tables, and late night hotel edits. I also tossed a Keychron low profile board and my LoFree Lite into the bag as backup. I hoped I would not touch them.

Day one, I opened the Cube at the airport, paired it in seconds, and felt pretty smug about the whole setup. On a flat surface it is a neat little magic trick. It disappears into a small pocket, then flips open into a full typing surface with a touchpad on the right. People notice. I typed notes, sorted email, did the usual travel admin, and thought, this might replace my bulkier travel boards.

Then I tried to use it how we actually work on vacation. On the couch, on the bed, on my lap while waiting in the lobby. That is when the clever design ran into the real world.

What it is and why it is appealing

The Nillkin Cube Pocket Foldable Bluetooth Keyboard with Touchpad is a compact, folding Bluetooth keyboard with quiet scissor keys. The right side doubles as a touchpad or a numpad. You toggle between pointer mode and number entry with a key press. It connects to multiple devices and switches quickly, so moving from a tablet to a phone to a laptop is easy. The whole pitch is simple. Carry one tiny thing, get a laptop-like keyboard and a touchpad anywhere.

When you are seated at a table, the pitch holds up. The keys are comfortable, the layout is familiar enough, and the integrated touchpad means one less gadget in the bag. For flights and cafés, this is exactly what I want a travel keyboard to be.

Where it stumbles in daily use

Two issues chipped away at the magic for me.

1) Touchpad reliability. Sometimes the cursor behaved, sometimes it hesitated, sometimes taps did not register cleanly. It never fully broke, it just did not feel consistent. Two finger scrolling worked most of the time. A few sessions were buttery smooth, then the next session felt a little stubborn. Not a deal breaker at a desk, a bit annoying when you are trying to work quickly.

2) Mode switching. The touch area doubles as a numpad, which is smart. In practice, switching between pointer mode and number mode sometimes took more than one press. I would think I was in numpad mode, start tapping numbers, and nothing would happen. Press again, then it would switch. The concept is great, it just needs to be more decisive.

Now the big one.

3) Hinge behavior on a lap. The Cube folds to stay portable, which is the whole point, but when unfolded there is no mechanism to lock it flat and rigid. On a desk, no problem. On a lap, the hinge wants to bend in the middle under normal typing pressure. It never snapped. I tried to break it on purpose and could not. It simply feels too loose for relaxed lap typing or couch gaming. The exact scenario that a portable, compact keyboard should excel at is the one that felt fussy.

The moment I switched back to a reliable board

By day three I was grabbing my LoFree Lite most of the time. It is a solid, one-piece low profile board. No hinge flex, no surprises, no touchpad quirks. The Keychron I packed as a backup did the same thing. They are both a little larger in the bag, but they just work in every position. Reliability beat cleverness once the vacation turned from novelty to routine.

That does not make the Nillkin a failure. It just defines the use case more narrowly. If you mostly type on tables, it shines. If you often type on your lap, you will likely end up reaching for something sturdier. Trust me I tried to find a lock method. But it didn’t exist the hinges are solid though, I even tried to break it at one point to see how far it bends. QUITE FAR, but that is the whole problem. This cannot be reliably used on the lap if it bends the wrong way!

Setup and pairing experience

Pairing was quick across devices and switching between them was smooth. The keyboard reconnects fast after sleep and keystrokes feel precise. I did not have to dive into obscure settings to make it usable. If you live on a tablet and a phone, or you bounce between a laptop and a TV box, the multi-device side of the Cube is genuinely convenient.

Typing feel

Keys are quiet, travel is short, and the layout is logical. I had no problem settling into normal speeds after a few minutes. For meetings, libraries, airplanes, and late night typing near a sleeping partner, the low noise level is ideal. There is no key backlight, so dim rooms may slow you down unless you are a confident touch typist.

Lap use, revisited

It is worth repeating because it is the deciding factor for many people. On a flat surface, the two panels lie even and the hinge stays out of your way. On soft or uneven surfaces, the middle wants to give. You can prop the keyboard on a book or a tray and avoid the problem. If you love couch typing, those extra props become a chore, and you will go back to a rigid board.

What would make it a winner

• A simple lock to keep the keyboard perfectly flat once unfolded. Even a low profile latch or a stiffened hinge would help a lot.
• More decisive mode switching for the touch area. One press, instant swap, zero doubt.
• A touchpad sensitivity toggle or a small firmware tweak to clean up the occasional missed taps.

With those changes, I would take it everywhere.

Who it suits

• Travelers who work at tables, counters, and tray tables more than on laps
• Tablet users who want a keyboard and touchpad in one tiny package
• Anyone who values quiet keys and multi-device switching over a rigid chassis

Who should pass

• Couch typists and bed editors who need real lap stability
• People who need flawless pointer input without learning any toggle rhythm
• Folks who prefer sturdy, one-piece boards to portable tricks

Pros

• Extremely portable, folds small, pairs fast
• Quiet, comfortable scissor keys for long sessions
• Integrated touchpad saves you from packing a mouse
• Multi-device pairing and quick switching
• Genuinely useful at a desk or café

Cons

• Hinges do not lock flat, lap use feels bendy
• Touchpad can be inconsistent, occasional missed taps or brief lag
• Numpad toggle sometimes needs an extra press
• No backlight, harder in dim rooms
• Wireless only, USB C is for charging, not wired typing

Verdict

The Nillkin Cube is a great idea that already works well in the places it is easiest to recommend, which are tables and tray tables. If your travel workflow lives there, the Nillkin Cube Pocket Foldable Bluetooth Keyboard with Touchpad is a smart, compact companion that can replace a separate keyboard and mouse. If your workflow often drifts to laps and couches, the hinge gets in the way and the touchpad quirks may annoy you enough to swap it out.

On my trip, I kept the Cube for desk work and reached for the LoFree Lite when I wanted no surprises. That is the summary in one sentence. Clever device, very useful in the right spots, not the all-positions answer for me. If your priorities match its strengths, you will probably love it.
