[Latest Upgraded USB C Power Meter Tester]: The multimeter tester can monitor Voltage,Current,Capacity,Electric Quantity,Power,Temperature,Resistance,Charging Time and other data of the USB or type C Port Devices.A Must Gadget checks the charging performance(charging speed and quality) of the output wall/car/solar panel chargers and USB charging cables.It can be also used to find the highest current of the Wireless Charger and test capacity and electric energy of power bank. [Latest Upgraded IPS Color Display Screen]: New upgraded version offers 8 IPS main color screen display interfaces,allowing switching the display interface by pressing the key.With the new interface settings,this instrument can monitor voltage,current,capacity,electric quantity,power,load impedance,D/D- voltage and other data of USB.(The upgraded IPS HD color screen is clearer than the old LCD color screen.Supports flipping the screen to 180 degree, and 3 kinds of personalized interfaces!) [Professional Safety Guard]: Featured with over-voltage protection, over-current protection, under-voltage protection, low energy protection and alarm system. This upgraded USB Type C tester can detect safety and maximally protect the appliances from damaging. It cut off output automatically and alarm by sound, while it save data when power off suddenly. [WIDE RANGE OF APPLICATION]: The USB tester comes with A OTG adapter, supports PD3.0/PD2.0, QC3.0/QC2.0 and multiple interfaces,this new multimeter supports the updated Pro mobile phone. (Support /X/ Xs quick charging, 29W power, 5V3A / 9V3A / 12V2.5A / 15V2A). It also can be applied to test other type C devices, such as Galaxy S9 Plus, ChromeBookPixel, , P9, . Please Kindly Note:When the ambient temperature changes or the outside heat conduction to tester causes the current to not return to zero and the display shows 0.01A or 0.02A or otherwise,Please Hold on the key button then insert to USB Charger It can make the current temperature of the ambient current zero calibration,After the zero can more accurate measurements.And when in Zero calibration,the output can not have any load current consumption, so usb tester display 0.00A.
