Is the XK04 Too Small for Comfortable Typing?
XK04 is designed for ultimate portability with phones and tablets, featuring a compact layout. For extended typing or full-size keys, we recommend our XK01 model with standard 16.5mm keycaps and number pad.
How to Connect and Switch Between Devices?
1. Unfold and Turn on the power switch.
2. Choose Bluetooth Channel: Press Fn+Q/W/E
3. Enter Pairing Mode: Long press Fn + Q/W/E
4. Connect via your device’s Bluetooth menu to “ProtoArc XK04”
Simply short press Fn + Q, W, or E to switch devices.
How Do I Know When My Keyboard Is Fully Charged?
A full charge typically takes about 2 hours.
The charging indicator is often red while charging and will switch to a solid green light once the battery is completely full.
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
