K2 USB Voltage & Current Meter – Professional PD3.1/EPR Testing Tool
High Precision Measurement
Supports voltage range 3.3–48V (K2-237) or 3.3–36V (K2-226), current up to 6A continuous (10A peak).
Display resolution reaches 0.0001 V / 0.0001 A for ultra-accurate readings.
Advanced Protocol Detection
Built-in recognition for PD3.1, EPR (28V), PPS, QC, SCP, and other fast-charging protocols.
Easily check charger output and cable performance in real time.
Color IPS Display
1.54-inch color IPS screen (240×240) clearly shows voltage, current, power, capacity (Ah/Wh), ripple waveform and frequency.
Compact and easy to read even under strong light.
This PC software is designed for USB testers to provide real-time monitoring and data analysis of USB charging and power performance.
- Displays Voltage, Current, and Power in real time
- Generates clear charging and power curves
- Records charge, energy, and total test time
- Shows Max / Min / Average measurement values
- Supports data saving and export for analysis
Ideal for USB chargers, cables, power banks, and battery testing, this software offers an intuitive interface and accurate measurement for professional and advanced users.
Professional Features
