ChargerLAB - Power-Z KM003C Portable USB-C Fast Charging Tester PD3.1 QC5.0 Digital Voltmeter & Ammeter Power Bank Tester - Black

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, and 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.
