Plugable USBC-VAMETER USB-C Power Meter Tester for Monitoring USB-C Connections Driverless

The Plugable USBC-VAMETER USB-C Power Meter Tester provides real-time insight into USB-C charging behavior by measuring voltage, current, and power flow between connected devices. Designed for inline monitoring, it helps users understand how power is delivered across laptops, phones, chargers, and USB-C accessories without interrupting normal operation.

Key Features of Plugable USBC-VAMETER

• At a glance - USB C Tester: Monitor USB-C power and charging. Measure voltage and amperage. Visualize the directional flow of electrical current. Updated OLED display is brighter and easier to read. New orientation button lets you flip the screen 180 degrees
• Bidirectional: USB power meter can be connected in either orientation, allowing for the full range of USB Power Delivery voltage from 5 to 20V (4V-22V, 50mA-6.5A operating range)
• Broad USB Support: Used as a data and power quality meter, device allows USB data pass through, USB-C Alt Mode video, USB-C charging. Use USB tester inline with USB-C docking stations, chargers, accessories, etc. Not compatible with Thunderbolt 3 devices
• Small and Tough: Small enough to go anywhere you need a USB C voltage meter. Even fits most phones and tablets without removing protective case. Strengthened USB-C connections ensure it's sturdy enough to be your go-to USB C power tester

Portable Diagnostic Tool

Its compact, lightweight form makes it suitable for field testing, travel kits, or desktop setups. The device can be used wherever USB-C power verification or troubleshooting is needed.

How it works

This meter is a transparent interposer–it should not interfere with the USB data (1.1 through 3.1 Gen 2), USB-C Alternate Mode video, or USB-C charging. The meter can be used in-line with USB-C docking stations, chargers, and other USB-C accessories. The meter is able to achieve this without interfering with normal USB-C operation as it only taps into the power (VBUS) and ground connections to measure values and leaves the data lines untouched.

Common uses

- Connecting between a USB-C host system like a laptop, tablet, or cell phone and a charger to monitor charge information.

- Connecting between a USB-C host and docking station to monitor charge information.

- Connecting between a USB-C host system and a USB-C bus powered accessory like an external hard drive, flash drive, etc to measure power draw of a device.

- Testing for USB-C port spec compliance such as a VBUS hot condition, voltage drop under load, etc.
