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.

Specifically for Phones and Tablets: Compact keyboard layout optimized for mobile devices provides physical typing capability for iPhone, iPad, and Android tablets with 10.76 x 4.07 inch unfolded size, ideal for on-the-go messaging and notes
Bluetooth 5.1 with 33ft Range: Connect to up to 3 devices simultaneously. Switch with dedicated keys – no re-pairing, no cable juggling.(Note: Turn on power before pairing)
PU Leather Protection: Integrated PU leather protective cover shields the keyboard from scratches while adding a premium look, letting you carry it confidently in bags or briefcases without additional cases
USB-C Rechargeable: Recharge with the included USB-C cable and rely on auto-sleep standby up to 150 days, so the travel keyboard is ready when your work moves
Space-Saving for Tight Workspaces: Compact layout with 0.55-inch keycaps fits comfortably on airplane trays, cafe tables, and limited desk spaces, letting you create a workspace even where desk room is minimal
