Description New Generation USB Tester: The upgraded color USB tester features a 12800 pixels IPS HD digital LCD color screen, which can clearly read data; the screen rotation function allows for reading in different orientations. Simultaneously, to achieve more accurate measurements, the USB instrument tester uses a sampling chip with an internal value as low as 1 milliohm (1 milliohm) to provide you with more reliable values and reduce consumption. Multifunctional USB Meter: The 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. The USB tester can automatically detect various fast charging protocols, including 2.4A/2.1A/1A/0.5A; DCP/; FCP 9V/2A, SCP 4.5V/5A; Qualcomm QC2.0/3.0. Memory Function in Case of Failure: The discharge process from 100% to 0 is required to test the battery capacity, which takes a long time to complete. The download function allows you to complete this process in one or more operations, as the capacity is accumulated again when 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, Easy 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, power banks, wall chargers, cables, etc., to display charging data in real-time. The USB tester is small and lightweight, providing a safe environment for you to charge anytime and anywhere. What You Get: 1 pack multimeter USB tester is clearly visible.
