Mavaol 2 Pieces USB Detector Voltage Current Tester Voltmeter Ammeter Portable for Mobile Phone Users (Weiß)
ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•The USB tester can measure the voltage when the USB power equipment is empty, as well as the voltage and current when the USB terminal equipment is working.
•With current and voltage cycle display, the USB tester is easy to use and convenient, it can be small and easy to carry, no need additional power supply.
•This electric energy tester adopts a new generation of 4 1/2 semi-integral cyclic conversion integrated circuits, equipped with an accurate bandgap reference source, which takes in precise range, high precision, stable operation, performance, strong anti-interference ability and high temperature.
•And this USB detector can be used to measure the power supply or power consumption of products such as USB interface, mobile phone ur, U disk, etc.
•In addition, such a USB detector can detect the amount of current charged by the mobile phone. It can also detect that the performance of the mobile phone ment line is poor. For example, a weak internal line can get the specified current from the mobile phone. If a high-impedance cable is used, the current of will not increase. Thus, poor performance is measured.
