—— Smart Visual Charging Station with Real-Time Power Monitoring
When Fast Charging Meets Smart Interaction
Most chargers simply deliver power. The ZX-3U39T goes much further.
This innovative 120W TFT Display GaN Charger combines high-power USB-C charging with an interactive display system that allows users to see exactly what is happening during charging.
Instead of guessing whether devices are charging efficiently, users can monitor real-time charging performance, temperature, power distribution, and charger operating status directly from the built-in TFT screen.
Designed for modern professionals, technology enthusiasts, premium brands, and OEM projects, the ZX-3U39T creates a new category between traditional chargers and smart power management devices.
A Charger That Communicates with Users
The centerpiece of the ZX-3U39T is its intelligent TFT display.
Using a touch-sensitive interface, users can switch between multiple display screens and monitor charger performance in real time.
