2PCs USB Detector Current Voltage Tester Voltmeter Ammeter Portable for Mobile Phone ChargersWhite

Feature: 1. USB tester can measure the voltage when the USB power supply equipment is no load, and the voltage and current when the USB terminal equipment is working. 2. With current and voltage cycle display, USB tester is easy to use and practical, which can be small and easy to carry, no need for additional power. 3. This electric energy tester adopts a new generation of 4 1 2 semi integral cyclic conversion integrated circuits, equipped with a accurant band gap reference source, which supports accurate range, high precision, stable operation, reliable performance, strong anti interference ability and high temperature resistance. 4. And this USB detector can be used to measure the power supply or power consumption of products such as USB interface, mobile phone charger, U disk and so on. 5. Moreover, such USB detector can detect how much current the mobile phone is charging. It can also detect that the performance of the mobile phone charging line is poor. For example, a low internal resistance charging line can get the specified charging current of the mobile phone. If a high impedance charging cable is used, the charging current will not go up. Thus, the poor performance is measured. 6. Easily measure the output voltage of the USB port and the working current of the equipment, the detector in compact size is without power supply and other auxiliary equipment, plug and play. 7. Meanwhile, USB tester can also detect whether the voltage and current output by the USB charger meet the standard, suitable for factories, laboratories and users.
