26VA USB Detector Type C Voltmeter Ammeter Battery Capacity Monitor Power Tester Discharge Voltage Current Meter Type A+C LED(USB-A and C(R-B))

AmmetersAttention:Because of the differet input & output ports there are 3 versions USBA USBC USBACUSB-C, USB-A+C version:1, When a device without PD protocol is connected to the USB-C output, it is normal that the meter does not display. You can press and hold the button "1" for more than 5 seconds to trigger the PD 5V voltage for other devices that do not support the PD protocol.2, When the input voltage exceeds 5.8V, the USB-A port has no voltage output, and only the Type-C port can be used. Type-C supports data communication function.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 and the charging head, it is not how many ampere the charging head is, the charging current will the same value, with longer charging time, the charging current slowly getting smaller, this is a normal phenomenon.When testing capacity, this meter only calculates the sum of the output of the two USB ports, excluding the conversion efficinecy of the front-end and the back-end device.If you choose Type-A,when OUTPUT1 connects to QC2.0/3.0, OUTPUT2 cannot connect to any device.Technical Parameters: Display mode: 0.28 "LED with red and blue digitsMeasurement accuracy: 1% (± 3 digits)Measurement rate: 500mS / timeDimension:69*29*19 mmInput/Test voltage:3.20-30.0VTest current:0.00-5.00ATest capacity:0-99999mA/HTest power:0.00-9.99-99.9-999WTechnical Function:Product Function DisplayDischarge the power bank through the USB discharge resistor to test the output capacity of the power bank:=Cm*Vm/Vb/E%: Calculated power bank capacityCm: The capacity displayed by the meter after the fully charged mobile power supply is dischargedVm: The output voltage value of the mobile power supply, usually 5V.Vb: The voltage of the battery in the power bank, usually 3.7V.E%: The conversion efficiency of mobile power supply varies with different power supplies, usually 85-90%.Connect the computer to charge the phone, at the same time, the mouse can still work:Charge one phone:Charge two phones at the same time:USB extension cable input, output at both endsTwo different USB devices can be charged at the same time, and the displayed current value is the sum of the currents of the two ports; the displayed capacity is the sum of the capacities of the two ports.One can be charged, and the other can be used for data communication (such as: USB mouse, U disk, USB mobile hard disk and other USB mobile devices), so that it will not occupy the computer USB interface more, and it also has the charging expansion function.The USB interface suitable for different orientations can easily see the display;
