USB MultiFunction Ampear & Voltage Detector Capacity Digital Tester

Description: USB MultiFunction Current Voltage Detector Capacity Digital Tester Monitor Meter

USB input port is plugged in 5V charger, USB output port is connected to mobile phone, directly read the current and voltage parametersMeasuring Micro USB line quality: USB output port is connected to mobile phone, USB input port is plugged in the 5V charger first, remember the voltage, then Micro USB input port is connected to 5V charger, remember the voltage. The smaller the voltage difference, the better the quality of the Micro USB lineUse TP4056 and other linear charging circuit, through this capacity table, to fully charge the battery with completely no power, the capacity data is the battery capacity, and using this method, you can also test the mobile phone charging capacityConnect this testing tool to portable power source and turn on it. Press the button until the capacity data is zero. Insert the cell phone to charge until the portable power source switches off automatically. The next time you open this testing tool, the display capacity is the portable power source output mAh
