Description: Can measure the output voltage of the USB port and the device's operating current. Small size, no power supply and other ancillary equipment, plug and play. It can measure the voltage when the USB power supply equipment is empty and load, and the voltage and current when the USB terminal equipment is working. Applicable to factories, laboratories, can also be used to measure the power supply or power consumption of USB interface, mobile phone charger, U disk and other products. Specification: Working Range: current (0-2.5A) detects cell phone charger voltage cannot meet standard DC5V. Working range: U=3~7.5V I=0~2.5A. Resolution: voltage 10mV current 10mA. Error: voltage
