FAQ

What devices & systems can these foldable Bluetooth keyboards connect to?

All our keyboards support Windows, macOS, Android and iOS systems. They pair smoothly with smartphones, tablets, laptops via stable Bluetooth connection. Multiple models support one-click multi-device switching to quickly swap between 2-3 paired gadgets. Contact us for details on connecting to other systems.

Optimized Bluetooth modules deliver steady transmission within 8–10 meters without signal dropouts. The sensitive touchpad and scissor-switch keys bring lag-free typing and cursor control for daily office tasks.

We adopt optimized silent scissor-foot mechanism for all our keyboards. It greatly reduces typing noise to avoid disturbing surrounding people, making it suitable for libraries, offices and public quiet spaces. Meanwhile, the structure brings soft, consistent keystroke feedback and long service life with durable rebound performance.

 Our exclusive proprietary hinge offers silky smooth fold and unfold hand feel. It locks the keyboard frame firmly for steady, comfortable typing feedback, and maintains consistent tightness for long-lasting daily use.
