About this item

• SAFE AND SECURE： Large current overload protection function, product design protection current does not exceed 2.7A, when the high voltage is accidentally connected, the protection board will automatically cut off the power to avoid unnecessary losses, and it will take a few minutes to resume normal operation.
• VOLTAGE AND CURRENT METER FUNCTION：When the mobile phone is repaired, it can be powered by USB connection, accurately detect the voltage and current value of the charger, determine whether the performance of the charger and charging line meets the requirements, can measure the power supply or consumption of the USB interface and U disk, and can measure the empty of the USB power supply device. Load/no-load voltage, load current when the USB terminal device is working.
• DISPLAY： Voltage and current dual LED display, real-time display of voltage and current, display battery voltage when the battery is inserted, display the power supply voltage when it is inserted, and the current is the load current. The bottom sponge cushion, the bottom of the PC board uses a thick sponge as the bottom buckle above the battery, which effectively reduces the strength.
• INTELLIGENT IDENTIFICATION OF POSITIVE AND NEGATIVE POLES：Due to different smartphone manufacturers, the battery interface of mobile phones is universal, the output positive and negative poles are different, and the power supply is opposite, the product can automatically identify the positive and negative poles of the battery.
