Giới thiệu Thiết Bị Đo Dung Lượng Sạc Điện Thoại Di Động Màn Hình Lcd Usb Tiện Dụng tại Lotte Market

Features:
Simultaneous display of voltage, current and mAH data for easy viewing
Can detect mobile power output mAH
Multi-group detection data storage, power-saving storage function
Does not affect data transmission
Higher accuracy, current parameters will not jump
USB male head and MicroUSB port dual power, can detect the quality of MicroUSB cable
Current sampling is 25 milliohms with less loss
With precise current calibration function, the current accuracy is higher (calibrated when shipped)

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%
Line loss: about 0.1 Euro
Test content: battery voltage, current, discharge capacity (10 sets of data in total)

Measuring voltage and current:
Plug the USB male head into a 5V charger, plug the female seat into a mobile phone and other devices, and directly read the voltage and current parameters;

Test the quality of MicroUSB cable:
Plug the mobile phone and other devices into the female seat, first plug the 5V charger with the male head of the machine, remember the voltage, and then use the MicroUSB cable from the 5V charger to the MicroUSB hole of the machine to remember the voltage and voltage difference
The smaller the distance, the better the quality of the MicroUSB cable.

Measure the output capacity and efficiency of mobile power:
First connect the machine to the mobile power supply, turn on the mobile power supply, long press the button until the capacity data is zero
, Insert the phone multiple times to charge it until the power bank is powered off and turn off automatically. The next time the machine is turned on
The indicated capacity is the mAH output by the mobile power supply. 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.

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

Data reset:
Press and hold the button for more than 3 seconds to clear the data of the current group.
