The Plugable USBC-VAMETER is a portable USB-C multi-meter that was designed to measure voltage and amperage (charge rate) for USB-C devices.

Introduction

Plugable is already well known for our advanced USBC-TKEY USB 3.1 Type-C (USB-C) Power Delivery Sniffer based on Google’s open source “Twinkie” design, but for many users it provides far more functionality than required and is more complex to setup (requiring a Linux computer). For most users a simple stand-alone, plug and play, on-the-go solution is required and the USBC-VAMETER is the perfect solution with its ability to display USB-C voltage, amperage, and current flow direction in real time.

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. This meter is not meant to replace professional USB-C testing equipment, it is designed for quick and easy measurements for users at any skill level.

Compatibility

We designed this meter to act as a transparent interposer which means it should not interfere with the USB data (1.1 through 3.1 Gen 2), USB-C Alternate Mode video, or USB-C charging. Can be used inline with USB-C docking stations, chargers, 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 their values and leaves all of the data lines untouched.

Product Features

  • Allows quick and easy monitoring of USB-C power and charging. Measures voltage and amperage as well as what direction the electrical current is flowing through it. Features bright and easy to read OLED screen
  • Meter is bidirectional and can be connected in any direction. Supports the full range of USB-C Power Delivery voltage from 5 to 20V (4-20V, 50mA-10A operating range)
  • The meter passes through all USB data (1.1 through 3.1 Gen 2), USB-C Alternate Mode video, and USB-C charging without interfering with normal USB-C operation. Can be used inline with USB-C docking stations, chargers, USB-C accessories, etc
  • The compact aluminum design makes this the perfect companion for diagnosing and monitoring USB-C devices on the go with no extra equipment required
  • We love our Plugable products and hope you will too. All of our products are backed with a 1-year limited parts and labor warranty and Seattle-based email support.

Good and Improving These testers are made in China, but do show a good build quality. This review will include two of these units since the first units board is starting to loosen. They sent me a newer updated model that will soon be available here. They have addressed some, not all, of the problems found in the first generation.

A bit annoying to read Initially I gave this product a 2 star review due to inaccurate pictures, however, pluggable responded in ~24 hours and fixed the product images to accurately show the features of the product.

It works as a meter, but design-wise leaves to be desired, both the case and the display. I opted for this instead of the Satechi one because Plugable is at least one known brand that is actually making an effort to push USB-C responsibly (i.e. following spec), and they had experience with the “Twinkie” device for USB-C analysis. Unfortunately I also ran into the same construction issue that a couple other reviewers did. The case came apart, one end pushing out the other end, and the tip of the device became slightly bent.
