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: Super compact and great connection sensitivity! - 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. ## Features - Palm-sized Folding Design with PU Leather Cover: Only 7.8 ounces – folds to a small size for carrying. The soft PU leather exterior protects against scratches and adds a premium feel. Slips easily into any pocket, bag, or briefcase. Perfect for business travelers, students, and digital nomads who need a keyboard wherever they go - Compact Layout: Unfolded size: 10.76"×4.07", keycaps 0.55". This mini keyboard saves desk space and fits on tight airplane trays or crowded cafe tables. Note: Due to the compact design (including the spacebar near the folding hinge), it may take 2-3 days to adapt your typing habit. Best suited for phone/tablet users writing emails, messages, and short notes. Check the dimensions before purchase - Bluetooth 5.1 with Stable 33ft Range: Connect to up to 3 devices (iPad, iPhone, Android tablet,etc) simultaneously. Switch between them with dedicated keys – no re-pairing, no cable juggling. Great for replying to Slack on your phone, then typing meeting notes on your tablet without missing a beat(Tip: Turn on power before pairing) - 2-hour Charge, 150+ Days Standby: Fully recharges via included Type-C cable (charging indicator turns green when done). Auto-sleep feature maximizes battery life of months of standby. No hunting for outlets during long trips. Perfect for remote work, travel, and daily carry - Your Reliable Partner for Mobile Creation: Draft a proposal in a café, journal in a park, or fine-tune a spreadsheet on a train.

I love this compact keyboard! This connected easily via Bluetooth and honestly is such an improved sensitivity vs the cheaper case with keyboard options.

Keyboard feels well-built and doesn't feel like a cheap keyboard at all. ### ⭐⭐⭐⭐⭐ Turned my Fold 7 into a legitimate workstation *by D***N on April 17, 2026* 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. ## 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: 2026-06-08*
