Abstract
Method, apparatus, and computer program product embodiments of the invention are disclosed for negotiation protocols for power delivery from a first device to a connected second device. In example embodiments of the invention, a method comprises: determining whether a connector includes a cable indication that indicates its cable is capable of conducting an elevated power level above a level of a legacy cable; transmitting an offer to a device connected by the cable, to provide one or more supported power capabilities above the level of a legacy cable, if the cable indication is determined to indicate that the cable is capable of conducting an elevated power level above the level of a legacy cable; and transmitting an offer to a device connected by the cable, to provide the power level of a legacy cable, if the cable indication is determined to indicate that the cable is not capable of conducting an elevated power level above the level of a legacy cable.
