1. Product Features:
Simultaneous display of voltage and current and mAH data for easy viewing
Can detect mobile power output mAH
Multiple sets of test data are saved, power-down save function
Does not affect data transmission
Higher precision, the current parameters will not jump
USB male and MicroUSB ports are dual-powered to detect MicroUSB line quality
Current sampling 25 milliohms, less loss
With precision current calibration, current accuracy is higher (it has been calibrated at the time of shipment)
2, Performance Parameters:
Input voltage: 3V-15V (actually within 15V)
Voltage resolution: 0.01V
Test current: 0.05A-3.50A
Current resolution: 0.01A
Capacity range: 0-19999mAH
Accuracy: plus or minus 1 percent
Line loss: about 0.1 ohm
Test content: battery voltage, current, discharge capacity (10 groups of data in total)
3, Function Introduction:
3.1, measuring voltage and current:
The USB male plugs in the 5V charger, and the female socket is inserted into the mobile phone and other devices to directly read the voltage and current parameters.
3.2, measuring the quality of the MicroUSB line:
Insert the mobile phone and other equipment, first use the male plug of the machine to plug in the 5V charger, remember the voltage, then use the MicroUSB cable to plug in the MicroUSB hole from the 5V charger to remember the voltage, the smaller the voltage gap, the better the quality of the MicroUSB cable. .
3.3. Measure the output capacity and efficiency of mobile power:
First connect the unit to the mobile power, turn on the mobile power, long press the button until the capacity data is zero, insert the phone to charge multiple times until the mobile power is turned off automatically. The display capacity is the mAH of the mobile power output the next time the unit is turned on. Note that this mAH is much smaller than the nominal mAH, output mAH* output voltage 5V / battery mAH * battery voltage 3.7V = mobile power efficiency.
 3.4, data switching:
Click the button to switch to the next set of data, and double-click the button to switch to the previous set of data.
3.5, the data is cleared:
Press and hold the button for more than 3 seconds to clear the group data.

4, Application Examples:
4.1. Test the charging voltage and current of mobile phones, tablets, mobile power supplies, etc.:
The USB plug of the detector is plugged into a 5V USB charger, and the female socket is inserted into the mobile phone, tablet, mobile power supply and other devices to directly read the voltage and current parameters.
4.2. Test the output voltage and current of the power supply and mobile power supply (must be matched with the loader):
The detector USB plug is plugged into a 5V USB charger, and the female socket is plugged into a USB loader to directly read the voltage and current parameters.
4.3. Test the voltage drop of the MicroUSB data line to compare the overcurrent capability of various wires (must be matched with the load):
The USB male connector of the tested data line is plugged into a 5V USB charger, the MicroUSB male plug is inserted into the MicroUSB socket of the USB detector, and the USB socket of the USB detector is plugged into the USB loader to directly read the voltage and current parameters.
4.4. Test the output capacity of the mobile power supply (must match the loader. Pay attention to the word “output”. The test here is not the nominal capacity of the mobile power supply. The nominal capacity of the mobile power supply refers to the total battery capacity inside. The actual output capacity is much larger! If you don't understand, please search for yourself):
The mobile power supply is fully charged, the USB plug of the detector is plugged into the mobile power supply, the USB loader is plugged into the USB socket and adjusted to the 1A file, and the power is automatically discharged until the mobile power isautomatically turned off (must pay attention to the heat dissipation of the loader!) The mAh data recorded at the time is the output capacity of the mobile power source.
A mobile power supply is equipped with three Samsung 2600mAh batteries (total capacity is 7800mAh), the ESD discharge result is 6108mAh, and the USB detector test result is 6117mah, which proves that the detector's capacity test is quite accurate!
