Portable USB Charger LCD Display Indicator LCD USB Power Charger Power Tester Mini LCD Voltage Current Detector
Product Description
Due to different input and output interfaces, there are 4 models: USB-A, USB-C, USB-D, USB-A+CUSB-C, USB-D, USB-A+C models: When the output device without PD protocol is connected, it is normal that the tester does not display. You can press and hold the button "I button" for more than five seconds to trigger the PD 5V voltage to other unsupported Devices using PD protocol. This meter can only measure and display in real time the voltage, current, power, equivalent impedance, accumulated capacity, electricity, time, etc. during charging or discharging, and does not have the function of boosting voltage, current or discharge. The size of the charging or discharging current is determined by the USB device to be charged and the charging head. It is not the number of A that the charging head will reach. The charging current will gradually decrease as the charging time increases. When testing capacity and power, the meter only calculates the sum of the outputs of the two USB ports, ignoring the conversion efficiency of the front-end and back-end devices. The input end of this product is directly connected to the output end with USB2.0 data communication; fast charging identification covers almost all fast charging protocols of the same type of charging interface;
