ProtoArc XK04 Foldable Compact Keyboard for Phone and Tablet, Black

A great product that exceeded my expectations & what was promoted on Amazon. Quick set-up, pairing with no issues, charged under 35 minute to full charge. Very reasonable price for what the keyboard can do. It is very lightweight & folds up to a small manageable keyboard. Will around the house from the patios & will definitely take on vacation. It is well built.

Very pleased with the size and function of this keyboard. It connected with my IPad almost instantly and re-connects each time I turn it on. The keys are close together due to it's size and it will take a few minutes to adjust, but everything works as advertised. I had a neoprene case from an old Nook and it fit in it perfectly. Since it is a new purchase and I've only used it a few times, I can't vouch for the durability, but it seems sturdy. One thing I especially like is the way it folds with no fold lines...just a flat, seamless keyboard. The battery life is more than adequate for my use.

I wasn't sure what to expect when I bought this. There's so much...stuff...on Amazon and I expected this to be decent at best. Once I got it open it was easy to connect and the keys felt satisfyingly clicky for such a small and purpose built design. I occasionally have to slow down to adjust to the shifted layout, but that will get better with time. I am very impressed with what I got for the price I paid and would recommend it to anyone who needs something small and portable that still offers an enjoyable typing experience.

I felt this keyboard met all my expectations. Compact, efficient, and long lasting battery. It provides a mini mouse pad even, when you fold it up. Sometimes you only need a keyboard for starting up, and launching programs, especially when you're getting ready for a gaming session. This was ideal for my latest work trip, and complimented my handheld PC nicely. Highly recommend this one! Easy to set up, and change the macro for F keys and media control. I didn't even notice any noise coming from the keys. It's compatible with windows, but that's all I tried it with. I used the Bluetooth feature. Great keyboard!

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.

I couldn't be happier with my ProtoArc Foldable Keyboard! As someone who is always working on the go, finding a keyboard that is truly compact, easy to pack, and comfortable to type on felt impossible—until I found this. It folds up incredibly small to fit in my bag, connects instantly to my devices, and the keys feel snappy and satisfying. What really blew me away, though, was ProtoArc’s customer service. I had a quick question about my device, and their support team responded almost immediately, resolving my inquiry with absolute kindness and efficiency. It is so rare to find a company that matches a high-quality product with genuinely outstanding customer support. 10/10 recommend—I'll definitely be buying from ProtoArc again!

This keyboard has a lot going for it... the weight alone speaks to the quality... I've had "cheapo" bluetooth keyboards before. This came in packaging that evidences great care and product excellence, and the keyboard itself has great features and oozes quality. For me, however, and my short stubby fingers, the hinge to fold the keyboard sits too close to the space bar & is about as high or higher than it - such that, at least for me, hitting the space bar is difficult with my right hand. I would need to work to change a deep-set pattern of typing to use this keyboard as my ONE keyboard, which is what I had intended it to be. (FYI - went with Logitech MX Mini - more $, but backlit & no hinge... love it.) For the price, it's probably the best folding keyboard I found on Amazon. Other than the hinge in the way, the keyboard is perfect size for typing for me. With careful use of a folding mechanism (first point of failure I imagine), this thing should last a long time. It's easy to pair, but I can't speak to switching between devices, since this was meant to extend my S23 Ultra to desktop (ish) use... ONE device for computing - in my pocket, with me always.

I love this thing! I bought one a while ago, but wanted to really use it for a while before reviewing. It works great! Small enough when folded to fit into my bag when folded and not very heavy to carry around, it is perfect for my needs. The charge lasts for a really long time, which is a very good thing as I keep forgetting to switch it off. Even then, I'm only charging it about 2 or 3 times a month at most. I admittedly don't use it heavily, but since I've forgotten to turn it off for several days at a time and still had it charged enough to work when I get back to what I was writing, that just makes it more impressive to me! I was surprised that the smaller keyboard size didn't cause me to make a lot of typos, but it was honestly very easy to adapt to. I was afraid when I bought it that it would be a cheap dud, but I am very pleasantly surprised. Some of the functions on it ARE hard to adjust to, but that's mostly because I'm used to using the number keypad to the right of keyboards and this doesn't have that. Overall, I'm very pleased with this purchase. 10/10!

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

This is a brilliant little device for typing comfortably from the truck cab. It folds up to the size of a small notebook, but the keys feel surprisingly normal and responsive when typing. The Bluetooth pairing was seamless. Perfect for anyone who travels heavily for work.

Hay que ver como dura, pero el diseño es excelente. La barra espaciadora algo chica y si usas el pulgar, un poco diferente, pero uno se acosumbre.

this is a terrific keyboard! Worked immediately. great size & light. Having the phone holder is big bonus for me. Practically means I rearely use my laptop or PC. Keyboard is EASY to use

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.
