Key Specifications

Real-Time Power Monitoring Benefits

The USBC-VAMETER3 delivers instant voltage and amperage readings through its bright OLED display, allowing you to verify your charger is delivering the correct power to your laptop, tablet, or phone. Unlike basic USB testers, this bidirectional meter shows the directional flow of electrical current, helping you understand whether power is flowing to or from your device. The updated OLED screen provides excellent visibility in any lighting conditions, and the orientation button lets you flip the display for easy reading regardless of how you’ve connected the meter.

Transparent Data Passthrough Design

This meter functions as a transparent interposer, meaning it won’t interfere with your USB-C data connections, video output, or charging capabilities. You can use it inline with USB-C docking stations, chargers, and accessories without experiencing any data speed reduction or connection issues. The design taps only into the power (VBUS) and ground connections for measurement, leaving data lines completely untouched for seamless USB-C operation.

Compact and Portable Form Factor

About the size of a standard USB flash drive, the USBC-VAMETER3’s compact design makes it easy to carry in your laptop bag or keep on your desk. The sturdy construction ensures durability during frequent use, while the black finish provides a professional appearance that won’t look out of place in any workspace. Despite its small size, the device delivers professional-grade measurements that would typically require much larger equipment.
