USB Tester USB Voltage Meter PD Trigger Voltmeter USB 3.0 Voltage and Current Tester

HIGH PRECISION DISPLAY: 5-digit/6-digit display with one-key switching, max resolution 0.00001, real-time monitoring of subtle changes involtage, current and power during charging. It can also detect the weak current when the original Apple data cable is no-load. FASTER TRANSMISSION RATE WITH USB 3.0: FNB48 uses USB3.0 interface, 9-pin pin design, compatible with USB2.0, transmission rate is 10 times that of USB2.0, and more energy-saving. RECORD MORE DATA: FNB48 can record up to 10 sets of measurement data. It could directly put the calculation formula of battery capacity on the tester, The calculation result is multiplied by 1000 to get the capacity of the battery, and the calculation is more convenient and faster. PD E-MARKER, DASH CABLE INSPECTION: FNB48 supports reading the data of E-Marker and DASH cables. After connecting the data cable, it is easy to read the chips of E-Marker and DASH cables. With analog DASH cable and Apple 2.4A acceleration function, it can directly charge and detect voltage and current without the original data cable. GRAVITY SENSING SCREEN AUTOMATICALLY FLIPS: The screen OF FNB48 can be flipped freely trough gravity sensing. You can also turn offthe gravity direction recognition, Long press the middle button to realize the screen flip.
