USB 3 Voltmeter Current Meter 0-3A 4-30V Display Current Voltage

The USB tester can be used to test the voltage/current. The tester uses high-definition IPS color liquid crystal display, multi-directional connector, high brightness and long service life.
Current and voltage data can be displayed simultaneously for easy display. It can also detect the voltage and current of various power supply outputs, as well as the quality of USB data cables.
Real-time detection of device charging status, voltage, current, power and other indicators, support QC2.0, QC3.0 identification. (As data is detected in real time, data may vary)
The internal use of professional instrument circuitry combined with a unique precision algorithm ensures the accuracy and stability of the product at the hardware and software level.
The tester is often used in testing the quality of 3C USB digital and peripheral products. Can be connected to laptop, mobile phone, desktop computer via USB ports.
