Description New generation USB tester: The upgraded color USB tester has 12800 pixels IPS HD color digital LCD display, which can read data clearly; The screen rotation function allows reading in different directions. At the same time, in order to more accurate measurement, USB instrument tester uses sampling chips with internal as low as 1 milliohm (1 meter ohm) to provide you with more reliable values and reduce consumption.Multi functional USB meter: USB meter tester is mainly used to detect USB charging current, voltage, capacity, , time, etc., to display accurate data for you in real time; Check the quality of the charger and cable to provide a safe charging environment for valuable equipment. USB tester can automatically detect different fast charging protocols, including 2.4A/2.1A/1A/0.5A; DCP/; FCP 9V/2A, SCP 4.5V/5A; Qualcomm QC2.0/3.0. failure memory function: the discharge process from 100% to 0 is required to test the capacity of the pack, which takes a long time to complete. The down storage feature allows you to complete this process in one or more operations, because capacity accumulates again when is applied again. Up to 9 sets of data can help you easily calculate the actual capacity. During this process or at night, you can turn off the screen for a non intrusive experience.Wide test range, simple operation: input/output voltage: DC3.6-30V, current range: 0-5.1A. Various USB meters can be widely compatible with USB-A port devices, such as mobile phones, tablets, laptops, car chargers, packs, wall chargers, cables, etc., to display charging data in real time.
