Plugable USB C Power Meter Tester — Monitor USB-C Power & PD (Driverless)

See USB‑C power in real time

Power your USB‑C workflow with clear, immediate insight into what your connectors are doing. The Plugable USB C Power Meter Tester sits in the line between a host and a device, translating electrical signals into easy‑to‑read information on a bright OLED display. It helps you observe charging behavior, verify power and data signals, and compare how different cables, chargers, or docks perform in real‑world use. Its compact, driverless design makes it a practical companion for daily checks at home, in the office, or on the road.

Key measurements include voltage and current, plus a visual trace of current direction. The upgraded display is brighter and easier to read in varied lighting, so you can check things at a glance whether you’re at a desk or away from it. The device is quick to set up and simple to interpret, so you can focus on your devices rather than the tool itself.

Bidirectional and wide‑range power monitoring

The meter supports USB Power Delivery readings over a practical voltage window, typically 4–22 V with currents up to 6.5 A. In normal PD operation you’ll see 5–20 V. This means you can observe how different chargers and cables perform under load, and you can rotate the connector without removing any components.

Broad USB ecosystem compatibility

Use it as a data and power quality meter to test data pass‑through, USB‑C Alt Mode video, and charging inline with docking stations, chargers, and accessories. Note that Thunderbolt 3 devices aren’t supported, so the focus is on standard USB‑C workflows.

Compact, durable, and portable

The unit is small enough to slip into a bag or attach to a keychain, yet rugged enough for daily use. It fits most phones and tablets in typical cases, and reinforced USB‑C connections maintain a reliable link during measurements.

What you can gain from using it

• Clear visibility of voltage and current in real time
• Insight into current direction and power flow
• Hands‑on validation of different cables, chargers, and docks

• Inline testing with docks and accessories without removing components
• Assistance for troubleshooting charging irregularities or performance bottlenecks
• Quick checks for Alt Mode video compatibility in USB‑C setups

Discover the potential of your USB‑C ecosystem with this versatile, driverless tester—the kind of tool that helps you understand how your devices actually use power.
