Do I need to use an EMCA cable for 3A at higher voltages?

Sorry for asking such a trivial question.

From my initial research I'm unsure if non-EMCA cables only support 5V/3A or also 9V/3A, 12V/3A and 20V/3A. So can I draw 60W from a non-EMCA cable?

Is the voltage relevant for the devices if the cable doesn't give any response?

Hello,

Yes, it will work with non-EMCA cables as long as the maximum current is defined less than or equal to 3A.

Hello,

Non-EMCA cables can support these voltages, only for carrying current of more than 3A we specifically require EMCA cables.

Any voltage level can be supported provided the source and sink are PD devices and they get into a PD contract, so yes non-EMCA cables can support 60W (20V/3A).

Hi Mallika,

thank you for the reply.

Will PPS of USB-PD V3 also work with non-EMCA cables if the current is defined at or below 3A?
