ProtoArc Foldable Compact Keyboard for Phone and Tablet, XK04 Pocket-Sized Travel Bluetooth Keyboard with PU Leather Cover, 3 Device Workflow for On-the-Go Typing - Black

The ProtoArc XK04 has been a great addition for getting work done when I’m away from my desk. It’s thin enough to toss in a bag for a coffee shop session before a meeting, and the setup is fast enough that it doesn't feel like a chore to pull out. I also use it at home to knock out a bit of work on my phone or tablet while watching TV in the evening. It isn't as rigid as a full-size desktop keyboard, but for the size, it’s surprisingly comfortable to type on and even works fine for gaming. The best feature is that it stores three Bluetooth profiles. Being able to toggle between a phone and tablet instantly without re-pairing is a huge time-saver. If you need a compact, reliable keyboard for travel or casual use, this one is hard to beat.

Bought this to pair with my tablet to make a more compact and travel-friendly work station! I love this compact keyboard! This connected easily via Bluetooth and honestly is such an improved sensitivity vs the cheaper case with keyboard options. It folds to about a hard-drive size and is super lightweight, making it extremely travel-friendly and easy to slip into any purse. Battery lasts really long. I've been using it for weeks on and off, and I still haven't needed to charge the keyboard. Keyboard feels well-built and doesn't feel like a cheap keyboard at all.

This is a well-designed product. It paired very easily with my Samsung Tablet and Samsung Phone. The keys are comfortable to type on for it being so compact. The keys have good travel and they look durable. When folded - the width and breadth are quite small, although the thickness is a bit more than what I expected - nothing bad, but whih it was a bith thinner. The mechanism at the hinge is impressive. I am typing this review on my phone using the keyboard. This will be a nice keyboard for travel. Keys are quiet as well.

Love this thing. I bought this to replace a logi pop keyboard that I got tired of toting around. I am a bit of a keyboard snob (love my mech keyboards) but this one is pretty good. It’s easy to set up. It’s easy to switch. It says about 3 seconds between presses but it takes a 1.5 for me. Folding it makes me feel pretty important and fits nicely in my bag. Maybe cargo shorts too. No double pressing or lag. It’s not quiet but it has a softer busy sound like any laptop keyboard. I feel I got a pretty good deal and no issues linking it to my iPhone and IPad. The only complaint I have is the hinge where the spacebar gets in the way. But honestly it’s going to be there on most foldable keyboards. Props to you if you type spacebar with the left since it will be a nonissue then. Also the phone stand is pretty solid. Had to take my pop socket off but it’s sturdy.

This keyboard genuinely surprised me. I picked it up to pair with my Galaxy Z Fold 7 and it has completely changed how I use that phone. Propped up in flex mode with the XK04 in front of it, the whole setup feels like a proper micro workstation rather than a phone trick. The fold mechanism is solid with no wobble or flex when typing, and the key travel is better than I expected from something this compact. Bluetooth pairing was instant and has stayed stable across sessions. The PU leather cover doubles as a stand and keeps everything protected in a bag without adding bulk. Typing speed comes up quickly. There is a short adjustment period to the layout, but within a day or two muscle memory adapts. Build quality feels durable and the whole package is impressively light given how sturdy it feels. If you have a foldable phone or tablet and you want to actually get work done on the go, this is the keyboard to grab. It earns every star.

After using this keyboard for approximately a month, I have found it to be a high quality product. Its build is both compact and solid, making it easy to carry and durable in everyday use. The keyboard functions seamlessly with my 13" tablet, offering smooth operation and reliable connectivity. I plan to test its compatibility with my other devices, including my cellphone, in the near future. While some users have reported issues with this keyboard, I am hopeful that I will not encounter similar problems as I continue to use it across different devices.

What with age and arthritis, I loathe smartphone screen keyboards. Typing is literally three steps forward and one or even two backspaced for me, with those. I bought this for those times when I have to type anything lengthy and all I have is the phone for communication. Camping mostly. I found this easily pairs with my phone and laptop, and though the keyboard is smaller than a normal full-size computer keyboard, I could comfortably and quickly type on it. It is a vast improvement over a screen keyboard. The key feel is different from a good laptop or separate keyboard, but still quite good. And it does fold up to a very small package, easily fitting in a backpack or pannier. (I'll be careful about it being squeezed or crushed, though.) My use has so far been limited. I won't make much use of it till this summer. So I can say nothing about longevity. There is also a very small phone stand that comes with it. This was helpful for the phone in landscape (horizontal) orientation, but wouldn't hold the phone (in an armored case) in a portrait (vertical) orientation. It would be nice if that were corrected.

This would be perfect - but it keeps losing its Bluetooth connection. I bought a replacement from a different manufacturer - but their ad lied about what charger it uses so theirs is already going back. This one - I get halfway through an email and it'll lose the connection. Then it's 2 minutes of fumbling around trying to make it work again, the tablet closing applications when it reconnects, and then me praying it won't do it again. First I thought it was battery, and I started using it plugged in (I'm using this in a truck). But it'll still do it. Calling this "frustrating" is an understatement. I'm surprised I haven't broken this over my knee yet and thrown it out the window. Someone explain to me WHY it's impossible to find a "full size" (or nearly full size) folding keyboard - that has BT 5.0, uses a USB-C charger, that doesn't have a useless number pad, that WORKS. I may just order another one of these and roll the dice again - but I'm beginning to believe all of these are junk no matter what you buy. I only need these things to work for like 30 minutes without having an issue. It's not like I'm on it all day. Let me write 1 or 2 emails and fill out a timesheet without any issue - BUT NOOOO - apparently that's asking too much. EDIT - I wound up buying a Samers KF08S keyboard instead. It looks just like this - but it's not the same. Slightly larger (actually full size), the power button seems better, and most importantly - it's been working perfectly. I'm using these with a Samsung tablet (a higher model, provided by my company) and I haven't had issues yet with the Samers model. The Procarc would cause all applications to close - if I turned it on AFTER I launched the app I needed. That was insanely annoying since everything requires a password on the tablet - and I can't shut that feature off due to company security. The Samers doesn't do that. I can turn the keyboard on and the tablet couldn't care less. It works exactly how you'd want it to work. Maybe it's the Samsung Tablet, the version of Android, the Proarc keyboard causing the issue - who knows. Your experience may be different. But the Samers model is almost exactly the same - just a little bigger - and everything on that has been working flawlessly. It's been a little while now and still no complaints with the Samers model. I can turn it on and start using it with any app launched on the tablet and it just works. First time, Everytime, it works. It causes no crazy problems like closing apps down, it connects quickly and just works. Amazing right? Something finally does what it's supposed to - without causing 3 other headaches in the process.

Really nice piece of gadget that fits in my small folio bag and is an excellent travel companion.

Good keyboard. Very portable.

I bought this folding keyboard mainly for its compact and lightweight format (I use it with iPad). It fits easily in a bag, unfolds within seconds, and provides a typing surface that feels very close to my 12” MacBook (2016) or the Magic Keyboard for iPad. The keys are comfortable and pleasant to use. Once unfolded, it feels like a full-size keyboard, so I don’t get the sense of being cramped. Even the slightly off-center space bar doesn’t bother me at all. The hinge falls under the right thumb, but that’s not an issue for me since I know what I bought and I accept the small compromises that come with a folding design. The build is entirely plastic, so of course it doesn’t have the premium aluminum finish Apple would offer, yet for the price I am genuinely impressed by the engineering behind it. Battery life has been perfectly fine so far. I sometimes type with the keyboard on my lap, for example on a plane, and while it can feel a bit less stable, it remains functional. The trick I found to prevent it from bending in the middle while typing is simply to support it with my thumbs underneath. It’s easy enough to do and doesn’t affect usability. I also customized it to fit my needs: I use a Canadian French layout, so I added stickers for certain keys, and I covered the brand name printed across the space bar since I didn’t like it showing. These small adjustments make the keyboard feel more personal. Overall, this is an excellent compromise between portability, comfort, and price. I was pleasantly surprised by its quality and practicality. It’s not as solid as an Apple keyboard, but for what it is, it works very well and I can carry it anywhere without hassle. With the added reassurance of a two-year warranty, I feel confident in my purchase. For now, I am very satisfied, and it’s proving to be a great little tool.

Excelente producto, no viene con la "ñ" pero se puede configurar desde la tablet para que tenga esa letra.

Folds into a small form factor, and extremely comfortable device to use. It was worth the purchase.
