PD decoy module uses 2721 hardware PD chip, can't be upgraded, can't change voltage, can't solve compatibility problemPDC004 uses a hardware PD identification chip.The identification of this identification chip is: tricking to trigger a fixed voltage.However, if the voltage that needs to be deceived is , the voltage will be applied to the file.For example: 15v product PDC004, your PD power supply is only 12V,Or no 15v file is 12v,then the scammer will apply to the 12v.PD spoofing is a communication , there will be no spoofing of higher voltages, and no voltage will be boosted or stepped down. It does not have the to change the power, voltage, and current of the power supply.Note:1. The hardware chip will randomly apply for voltage, for example, you need a 15V model.It may other voltages2. Hardware chip, can not be upgraded, can not voltage3. Does not support charging head information reading4. Does not support other gears except for fixing a few voltages, such as PPS gear5. You forced a 12V computer with 15V, causing the computer to overheat and cause a fire.6. Does not support PPS gear arbitrary voltage 7. Does not compatibility with most charging headstype:12VColour:blueMaterial:PCB+metalPackage Contents:1 x PD decoy moduleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
