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.

My son who is a missionary in a remote place where he does not have access to a computer and only uses a smartphone, wanted a bluetooth keyboard that he could use to type emails and other things like that. I searched through so many descriptions of different keyboards and finally settled on this one. Before sending it to him directly though, I got one for myself to see if it would be a good fit for him. Oh, my gosh! I am in love with it! It makes typing text messages, and other things that I usually struggle with on a phone, so much easier. It seems to be super high quality materials, and the engineering of how it folds and works is fantastic. Hats off to the developers. Pros: Smaller than my phone, it's easy to carry along. The keys are weighted to feel like keys on a regular keyboard. Pairs easily. Types great in all the applications I've tried it with, ie, Word, Notepad, 365, texting, emails. The little phone stand is adjustable and sits firmly on a flat surface, holding the phone at any angle I need. Cons: The keyboard is a little smaller, about 1.5", than a full-sized keyboard, but I play the piano, so I use the same techniques of curved finger positions and it doesn't bother me at all. My husband, who has a tremor, can't use it though. It's too small for him. Also, I think I will have to be careful with the phone stand. It may be a bit more fragile than the keyboard, but I still love it. Also, I do wish the on/off switch had an automatic off for if I forget to turn it off, but that's so insignificant that I still rate it 5 stars. If it continues to work well, this rating will stand. If it fails in the next year, I'll change my review.

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.

This is a fantastic product that feels really comfortable to type with. The size is spot on for me. It works perfectly with my phone and tablet, too. My only complaint, which is pretty minor but worth noting, is that there's no way to lock it into the open position (at least not that I noticed). Sometimes I want to type with something on my lap, and because if doesn't lock, you can't really do that. Fortunately, I have a lap table thing, but I don't always have that available. That's it, though. Like I said, pretty minor. This is a great product and a tremendous value, and definitely worth checking out of you're in the market for a highly functional, portable keyboard.

When ordering this keyboard I figured it’d be a typically cheap and poorly made product like many other budget tech on Amazon. In reality, this is a very well-made foldable keyboard and I was surprised by the quality. Very responsive, very light, and folds to a great size. Comes with a nice charging cord as well. Great packaging. Set it up in about 30 seconds and was immediately usable. Would highly recommend to anyone looking for a portable keyboard — works great with my Lenovo Legion Go

Writing my review with the keyboard right now. Bought this for use with my IPad Pro 13”. After long angst of trying to decide between keyboard and cover combo or individual components, I went with a standard cover that can hold the Apple Pencil and this ProtoArc Keyboard. Super glad I went this way. This key board is extremely well made, good looking, portable and the manufacturer is dedicated to quality and helping their customers. ProtoArc gives great supporting documentation and is sure you have their contact if you have issues. I was able to easily pair the key board with three devices, my IPad Pro 13”, my android phone and even my Supernote e-ink book. Very easy switch between devices. Only thing to consider, if you have large hands and expect to do a ton of typing this might not be for you.

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.

I bought this to pair with my recent purchase of a Lenovo Legion Tab 3 Android Tablet. I liked the idea of this version over the full size XK01, since this is a small tablet. Bluetooth pairing was fast and painless. I haven't tested the 5 month battery life claim yet, but so far, no problems. The really good things: ~ Key travel is great despite being so thin. ~ The fold is super smooth, never gets stuck. ~ It does fit in my pocket, but I am neither skinny nor are my pants. ~ Solid build quality. The bad (well not bad so as challenging): ~ The placement of the space bar... I get it, though, it has to fold in the middle so the space is slightly offset. I thought this would throw off my writing, and it did for about a day. However, I quickly developed the muscle memory and now I have no missed clicks. Pretty easy to get used to. Would I like keys that are like 10% larger, YES! I really don't travel with this in my pocket, so a slightly larger size would not matter to me. I am super impressed with this product and it is my first Protoarc product. I was doubtful about their PC mice and trackballs, but based on this I would be willing to try one of their mice.

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.
