It can deceive the 5V/9V/12V/15V/20V voltage, can simulate the new fast charging mobile phone protocol, fully cover the PD2.0 protocol trigger, and identify the true and of the device, with the voltage range and mode -off memory functionThe V+ key can be used to increase the voltage protocol for the single machine. Double-click or long press to send 5V/9V/12V/15V/20V trigger protocol in turn, with -off memory function, which improves the efficiency of batch testing of factory production linesC male input: to fast charging devices such as chargers and banksC female input: to fast charging devices such as chargers and banks through the C-C data lineA female input: to constant current aging load meter or supply to equipment with corresponding voltageColour: as shownMaterial: ABSPackage Contents:1 x supply change board moduleOnly the above package content, other products are not included.Note: Light and different displays may the color of the item in the a little different from the real thing.
