Voltage level and mode power-off memory function. Accurately display the current voltage values and load current values. Easy to operate and convenient to use. Improve the testing efficiency of factories or production lines. Can be used to identify the authenticity of equipment and distinguish the quality of the equipment. This board comes with PD protocol, which can quick recharging mobilephones to trigger PD rechargers with 5Volt, 9Volt, 12Volt, 15Volt, and 20Volt voltages. The dual digital display (displaying voltage and current) has a male and female input test port, which can test PD rechargers. When paired with a load, it can also test the output voltage and current values of PD data lines.
