Some of the benefits of using USB-PD adapters are: Standard USB power delivery can be used at up to 100 W (prior USB power was limited to 5 volts at 1 or 2 Amps). Compatible devices can program the actual output power and voltage needed, regardless of what USP-PD adapter is used. Engineers can qualify a USB-PD adapter once and continue to use the same adapter on other designs, potentially reducing their overall qualification time and effort. Adapters use common connectors and pinouts, no unique parts needed for use. As with single output adapters, regulatory safety compliance is handled at the adapter level, avoiding lengthy regulatory qualification on the end device.
