When the battery is full of electricity, the circuit will determine whether the battery is full, so as to cut off the power supply, prevent excessive charge and cause explosion
Due to different manufacturers of smart phones, led to the battery battery positive and negative poles are different, the product can automatically identify the positive and negative cells
In the mobile phone repair process, can be connected through the USB power supply voltage, accurately detect the charger and current values, in order to determine whether the performance of charger and charging line to meet the requirements, can measure the USB interface, U disk and other power supply or power consumption, can measure USB power supply equipment load and load voltage, load current USB terminal equipment at work
This product design protection current is not more than 2A, when accidentally access to high voltage, the protection board will automatically cut off the power supply, to avoid unnecessary losses, broken after 1 minutes to return to normal work
With voltage, current display in real time, when the battery is inserted, it shows the voltage of the battery. When plugged in the power supply, it shows the voltage of the power supply, and the current is the load current
