Review: Excellent, highly portable setup for mobile work - 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. Review: A compact well designed wireless key board - 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. ## Features - Palm-sized Folding Design with PU Leather Cover: Only 7.8 ounces – folds to a small size for carrying.

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.

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. ### ⭐⭐⭐⭐⭐ Sturdy, High quality materials, comfortable to use, I love it! *by S***L on March 6, 2025* 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. ## Frequently Bought Together - ProtoArc Foldable Compact Keyboard, XK04 Portable Bluetooth Keyboard with PU Leather Cover, Pocket-Sized Wireless Travel Keyboards for iPad, iPhone, Smartphone, Tablet and Laptop - Black - Logitech M196 Bluetooth Wireless Mouse, Compact and Portable Mouse for Laptops, Tablets and More, 12-Month Battery, Smooth Tracking, Compatible with PC and Mac, Windows and macOS - Graphite --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/656816912-protoarc-foldable-compact-keyboard-for-phone-and-tablet-xk04-pocket](https://www.desertcart.sg/products/656816912-protoarc-foldable-compact-keyboard-for-phone-and-tablet-xk04-pocket) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-06-19*
