Instructions:
Voltage and current measurement:
Plug the USB male into a 5V charger, and plug the female into a mobile phone or other devices to directly read the voltage and current parameters
Measure battery capacity:
By using linear charging circuits such as TP4056 to fully charge a completely dead battery through this capacity meter, the capacity reading is the battery capacity. This method can also measure the charging capacity of mobile phones, and even calculate the charging efficiency of mobile phones.
Measure the output capacity and efficiency of mobile power supply:
First, connect the mobile phone to the mobile power supply, turn on the mobile power supply, press and hold the button until the capacity data returns to zero, and insert the phone multiple times to charge until the mobile power supply runs out and automatically shuts down. The next time the machine is turned on, the displayed capacity is the mAH output of the mobile power supply. Note that this mAH is much smaller than the nominal mAH, with output mAH * output voltage 5V/battery mAH * battery voltage 3.7v=mobile power efficiency
Data reset:
Press the reset button for 3 seconds and the screen will display reset.


Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
