For a multimeter, the Plugable USB-C Amperage and Voltage Tester (USBC-VAMETER3) manages to fit a lot of useful features into a sturdy little package. About the size of a USB flash drive, this bidirectional USB tester allows for full USB data passthrough while it monitors USB-C power and charging, measures voltage and amperage, even visualizes the directional flow of electrical current–all in real-time.


Connect the USBC-VAMETER3 inline between a USB-C host system like a laptop, tablet, or cell phone and a charger to use it as a USB voltage meter or power consumption meter. An updated OLED screen means a brighter and easier-to-read display in any lighting conditions, and a new orientation button lets you flip the screen with a click.

Nicholas ★★★★★

Finally, a USB meter that actually handles my 140W laptop charger without freaking out. The bidirectional readout makes it easy to see voltage sag under load, and the readings matched my bench meter within 0.02V.

Lily ★★★★★

It’s barely bigger than a flash drive, which makes it perfect for tossing into a laptop bag without noticing it’s there. The live voltage and current readout on that little screen is surprisingly clear, and it handled my 140W charger without so much as a warm case.

Abigail I. ★★★★★

The bi-directional detection is a lifesaver for debugging whether my laptop charger is delivering the full 20V it should. Finally know my cables aren't the bottleneck.
