USB Charging Current/Voltage/Power Tester and Analyzer (แบบมีสาย) Black USB LCD Voltage Current Detector

USB Charging Current / Voltage Tester (แบบมีสาย): 

อุปกรณ์ตัวนี้ประยุกต์ใช้งานได้หลายประเภทดังนี้

Test the charging voltage and current of the mobile phone, tablet, mobile power, etc.
Detector USB male plug in 5V USB charger, female plug phone, tablet, mobile power and other equipment, directly read the voltage and current parameters.

Test power supply, mobile power output voltage and current (must match the loader):
The USB male detector plugs in a 5V USB charger, and the female connector inserts the USB loader, which directly reads the voltage and current parameters.

Test the mobile power output capacity (must match the loader. Note "output" word, here is not testing the mobile power nominal capacity, mobile power nominal capacity refers to the total battery capacity inside, is The actual output capacity is much greater! If you don't understand, please search for it yourself
The mobile power supply is fully charged. The USB plug of the detector is plugged into the mobile power supply. The USB socket is plugged into the female seat and adjusted to 1A. The battery is discharged until the mobile power supply automatically shuts off (pay attention to the heat dissipation of the load!). The recorded mAh data is the output capacity of the mobile power supply.

Due to time constraints, the owner did not do a detailed test and cited an Amoy friend's test picture:

A mobile power supply equipped with three Samsung 2600mAh batteries (total capacity of 7800mAh), with EBD discharge results of 6108mAh, with the USB detector detection results of 6117mah, proved that the tester's capacity test is quite accurate!

• Simultaneous display of voltage, current, and mAH data for easy viewing
• Can detect mobile power output mAH
• Multiple test data storage, power-down save function
• Does not affect data transmission
• More accurate, current parameters will not jump
• Current sampling 25 milliohms, less loss
• With precision current calibration function, higher current accuracy (already calibrated when shipped)

• Input voltage: 3V-15V
• Voltage resolution: 0.01V
• Test Current: 0.05A-3.50A
• Current resolution: 0.01A
• Capacity range: 0-19999mAH
• Accuracy: plus or minus 1%
• Line loss: about 0.1 ohms
• Test content: battery voltage, current, and discharge capacity (a total of 10sets of data)

Function introduction:

- Measuring voltage and current: The USB male plugs in 5V charger, female inserts the mobile phone and so on equipment, reads out the voltage electric current parameter directly.

- Measuring mobile power output capacity and efficiency: First connect the unit to a mobile power source, turn on the mobile power, press and hold the button until the capacity data is zero, insert the phone and charge it repeatedly until the mobile power is turned off automatically.The next time you turn on this unit, the display capacity is the mAH of the mobile power output. Note that this mAH is much smaller than the nominal mAH, the output mAH* output voltage is 5V/battery mAH* battery voltage is 3.7V = mobile power efficiency.

- Data switching: Click the button to switch to the next set of data, double-click the button to switch to the previous set of data.

- Data clearing: Press and hold the button for more than 3 seconds to clear the group data.
