USB Meter Digital USB Current and Voltage Meter Tester Multimeter 4V 30V 0 3A USB Current and Voltage Capacity Detector LCD Display

This USB current voltage capacity tester Crafted from high-grade LCD monitor with low power consumption feature, bright and clear enough to monitor the parameters on the screen. Simultaneous display of voltage and current and mAH data for easy viewing. The mobile power output MAH can be detected. With precision current calibration function, the current accuracy is higher, more accurate, the current parameters will not bounce, current sampling 25 milliohms, less loss. Multi-group detection data storage, power-down save function, does not affect the data transmission. USB male and Micro USB port dual power, can detect Micro USB line quality. It can be used to find the charging problem of digital devices, USB male and Micro USB port dual power, can detect Micro USB line quality.
