USB C Power Meter 4-30V 0-6.5A
This USB C tester measures voltage, current, power, capacity, energy, temperature, resistance and charging time on Type-C devices. It operates from 4 to 30 volts and handles up to 6.5 amps for a maximum of 195 watts. The unit stores capacity and energy data when power is lost so you can review results later. It is aimed at digital enthusiasts and anyone checking charger or cable performance.
Replaces basic single-readout meters
A simple voltmeter only shows one value at a time and loses data when unplugged. This tester cycles through multiple screens with one button press and rotates the display with a double-click. The jump is worth it when you need to log full charge cycles, verify fast-charge protocols such as QC 2.0, 3.0, 4.0 or Super VOOC, or compare capacity across power banks without manual notes.
Check your charger and cable ends before ordering
The screen lights automatically with a USB-A source but requires a load connected on a PD source to power up. You need a Type-C charger and a Type-C device or load to use all functions. Calibration also demands a connected load when powered from a PD charger. If your setup uses only legacy USB-A ports, the tester will still work but protocol detection is limited to what the source supports.
