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.
