    • With a five-bit or six-bit display that can be switched by one button, with a maximum resolution of 0.00001, this USB tester can real-time monitoring of the subtle changes in voltage, current and power during recharging.
    • Digital 6.5A USB power meter uses a USB 3.0 interface, a 9-pin design, and is downward compatible with USB 2.0+ times the transmission rate of USB 2.0. There is no need to use the primary data cable, it can also directly test the recharger agreement of some mobile phones.
    • The 120W USB meter can record 10 sets of measurement data, you can use the data you get to calculate the capacity of the battery, and directly add the calculated formula on this product, the result is multiplied by 1000 to get the capacity of the battery.
    • Small USB voltage tester supports reading the data of E-Marker and DASH cables, and the chips of E-Marker and DASH cables can be easily read after connecting the data lines and supports screen flip function, through the gravity-induction, the screen can be free to flip, you can also turn off gravity-direction recognition and flip the screen by long pressing the middle key.
    • It uses the differential pressure method to measure cable resistance. It is used with constant current load to easily detect cable resistance.

    Tips: Can a USB tester be a Voltmeter?

    Yes, many USB testers incorporate voltmeter functionality. A USB tester is a versatile tool that often includes the ability to measure voltage, current, and power in a USB connection. The voltmeter function specifically allows users to monitor the voltage level of the USB power source in real-time.

    By connecting a USB tester between a USB power source and a device, users can observe the voltage on the tester's display. This feature is particularly useful for assessing the stability of the power supply and ensuring it meets the required specifications for charging or powering USB devices. So, in essence, a USB tester can function as a voltmeter when monitoring USB power sources.
