Multi-function tester: voltage/current/power 3-in-1, quickly test the voltage, current and power of 3C digital products such as mobile phones, computers, hard disk boxes, etc. High-definition TFT color screen, USB/Type port can be plugged in for detection, TFT color screen displays current, voltage and power. Power, current and voltage recognition are accurately measured to 3 decimal places. Detection while transmitting: Data can be transmitted simultaneously during detection without affecting the transmission speed. The transmission speed of the USB-A interface is up to 10Gbps / the transmission speed of the Type-C port is up to 40Gbps. Detection while charging: Charging can be done at the same time during detection without affecting the charging speed, supporting 0-90W super fast charging. Instrument sampling circuit, intelligent temperature control, real-time monitoring of slight changes in voltage, current, power, etc., to achieve accurate measurement. Monitoring voltage:DC4-30V Monitoring current:0-3A Monitoring power:0-90W Interface type and Transmission rate:USB-A, 10Gbps/Type-C, 40Gbps Colour:Space Gray Material:Aluminum Alloy Package Contents: 1 x Voltage Current Power Tester Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is 1-3cm.
