Product Name: LCD USB Mini Voltage and Current Detector USB Charger Tester Meter
Forget the hassle of evaluating digital device charging problems yourself, dive into the world of intelligent device testing with our functional and efficient LCD USB Mini Voltage and Current Detector USB Charger Tester Meter. Designed to be compact, this tester’s dimensions are 58 28.5 15mm (excluding cables), with a wire length of about 16cm.
Quite versatile, this tester effortlessly checks USB charging current, voltage, and discharge capacity. The tester comes with a functional button that serves for viewing and switching between test data. More than that, you can bank upon its good memory as it can store up to 10 groups of test data.
The USB output port, in an inclusive move, has been designed to connect with a variety of components including data cables, discharge resistors, and any other cable device that possesses a data communication function. The data transmission will not be compromised in any way.
Kindly note the testing limits: the voltage and the current should not exceed 7V and 3.5A respectively. A unique ‘LCD alert’ feature of this tester is when the voltage dips below 4.7V or crosses 5.3V, the LCD screen will flash. However, this does not hinder its functionality.
To illustrate an example for a 3A setting, just set your electronic load to 3A and watch as the current is finely adjusted. This process, visually mirrored in the LCD screen, would take around 10 seconds. Once you see the 3A result, turn off the electronic load, as the process is successful. The settings will automatically be saved.
Testable Parameters:
Battery Voltage
Battery Current
Discharging Capacitor Value (Total of ten parameters)
For a data reset, press the button until the parameters switch to the next set. Release the button and the new parameters will initiate from zero.
Worried about overvoltage or undervoltage? These are visually signified by an arrowhead appearing on the LCD screen and simultaneously, the LED background will flash.
Package Includes:
1 x LCD USB Mini Voltage & Current Detector USB Charger Tester
Let’s put it to the test:
The charger capacity test revealed that it handles a 2A discharge resistor with a voltage of 5.27 V, and 2.01 A current, similarly, with a 1A discharge resistor, it sustained a voltage of 5.30 V, with 1.02 A current. Likewise, the charging quality test handled a 1A discharge resistor with a voltage of 5.09 V, and 2A discharge resistor had 4.97 V.
Below, let its detailed pictures speak louder than words!
