ProtoArc Ergonomic Foldable Keyboard, XK03 Split Folding Travel Bluetooth Keyboard, Ultra Slim, Portable for iPad, iPhone, Tablet, Laptop, PC

This is the best keyboard i've used possibly ever? It folds nice and flat, so easy to set aside if I need my desk space. it's more comfortable to type as well. The only drawback would be if you have a PC and not a Mac (I have a mac). I haven't had any issues with bluetooth connectivity or battery dying either. The charge actually lasts a long time, and I don't even know how long because I charge it every couple of weeks to make sure it doesn't run out of charge while I'm using it.

I bought this as a travel gift for my partner and he absolutely loves it. It’s sturdy when unfolded and has a nice feel on the keys. Soft touch and high quality. The carrying bag is great. It folds right up into a backpack.

Outstanding across the board. Quality hardware materials. What design. Good key feedback, solid. Folks solidly. Compact design. Good Bluetooth connection, instantly detected. A must have in my backpack for mobile work.

I like that the size and design makes it feel more like a folding full-sized keyboard. I was able to pick up the ergo layout quite quickly and it feels great when I type on it. The keys themselves feel nice and the travel they have is decent. Key actuation is accurate, soft and feel like Logi's MX mini keyboard. It's also much quieter than other folding keyboards because it has a "leather" housing rather than the folding mechanisms and complex hinges that others use. I've owned several portable keyboards and I can never type fast on them because their smaller size doesn't match my muscle memory. Using those keyboards for an extended period of time was something I would avoid. The design of this keyboard mitigates that issue. It did take me a few minutes to adjust to the ergo layout but it feels natural. My only concern lies with the "leather" hinge that could potentially wear over time. I wish ProtoArc would have included a case for this keyboard since that would help protect the hinge when on the go. Luckily, one of the cases I had for another folding keyboard fit. I intend to throw this into my daily use backpack. I will report back if I notice any issues, degradation, or wear that I find concerning. I've been using this with my Steam Deck and my iPad and it's worked extremely well. Overall really happy with this purchase so far. Pros: - Turns on immediately after you open it; remembers last device (1-3) used - Keys don't feel cheap like other folding keyboards - Less noise overall especially while typing; keys don't "chatter" like on other keyboards - No issues with keys not activating when pressed with reasonable force - No complex hinges or moving parts Cons: - No case was included - "leather" hinge could wear down with age

This is a really good keyboard. Ergonomic. I've had a few other portable ergonomic keyboards and it's my preference and this one is great. It's the best portable keyboard I've found because it's ergonomic. Cause I like ergonomic keyboards.

I recently picked up this portable foldable keyboard, and it’s been fantastic. It’s lightweight, easy to carry, and folds up so small and flat that it easily fits in my bag and barely takes up any space. Despite its compact size, it feels sturdy and comfortable to type on — much better than I expected. It connects quickly and works seamlessly with my devices. Perfect for travel, working on the go, or even just keeping my desk clutter-free. Holds a charge for a long time too! Highly recommend it if you’re looking for a portable, reliable keyboard!

Amended review 1/6/2026: The TAB key stopped working in November followed closely by the left space bar. I tried to remove the keys to clean underneath in case dust was the problem but they would not pop back in place no matter what I did. I ordered a replacement keyboard but it shouldn’t have worn out that quickly. I am gentle with my devices, I never dropped the keyboard, kept it clean, put it in a protective case when traveling, etc. so I am disappointed. ——————- This a very lovable little keyboard! It connects easily via Bluetooth and will remember 3 devices. The battery life is fantastic, I use it for days at a time of full-time work between charges. It’s quiet and low profile and feels roomy for such a small size. The keys were almost too widely spaced for my lady hands but I adapted quickly. It’s highly portable, being about the size of a thin paperback book when it’s folded. It has a gentle magnetic closure. The texture of the backing material is leather-like and prevents slippage on a desktop. It arrives neatly packaged with a relatively sophisticated box and sleeve. The quality is impressive for the price. Suitable for gift giving, if you need a practical gift for someone on the go. My only complaint is the ESC button - the blue accent mark looks like a defect. It drove me crazy at first but I’ve learned to ignore it. Pictured in photo. [I’m shopping the ProtoArc store again now because I’m so pleased with this product. What I really need is a portable ergonomic keyboard with backlighting and a detachable keypad and touchpad. Is that too much to ask…? Help me, ProtoArc!]

Let me start by saying I would absolutely buy this keyboard again. It packs up well, has great travel to the keys, lays flat which suits my ergonomic preferences, and it remembers THREE devices and a rapidly switches between them. I use it on my work PC, Android phone, and my personal PC. It lives in my backpack and I've used it nearly every single day for over 6 months now. Battery life is excellent at well over two weeks per charge with HEAVY daily use. I only have two negatives: It absolutely needs a dedicated delete key and the navigation arrows are comically small. Other than these two minor gripes, I have no notes.
