Voltage and current curve painting with sample rate up to 100 samples per second.

High precision measuring wire resistance: Two mode of wire resistance test, 4 Wire Kelvin and Voltage Drop.

Full protocol power-free automatic protocol detection, the list shows almost all fast chargers supported by the charger.

High accuracy measurement, the accuracy can tend to 0.00001A.

All female ports are fully built in, and the terminals are not protruding and are not easily damaged.

PD2.0 and PD3.0 fast charge protocol list and trigger supported.


*Do not access any equipment that can't withstand high voltage. Fast Charge Trigger may request high voltage output. Output of 9V is able to burn most of cell phones that are not supports fast charge!

**Due to all the ports of USB meter(includes the input ports of Micro USB and Type-C) will have a high voltage output after fast charge trigger is on. Do not access any equipments that can't withstand high voltage like the USB on computer, or the equipment will be burned.

***Adjusting current or voltage on your own is not recommended. You can choose default settings if you think the value is not correct.
