LED Digital USB Voltage Current Meter Tester Power Detector Charger

Sensor Ammeters Attention: The instrument can be tested in real-time voltage current power charging or discharging the cumulative capacity. Do not have the boost voltage current or discharge device function. Charge or discharge current is determined by the size of the USB device to be charged with the charging head With longer charging time the charging current slowly getting smaller this is a normal phenomenon When testing the capacity of the power meter to calculate the sum of only two USB ports output excluding the front-end equipment and back-end equipment conversion efficiency; For ultra-high capacity precision please pass. When OUTPUT1 connects to QC2.0/3.0 OUTPUT2 cannot connect to any device.
