USB-PD Type-C AC/DC charger / adaptor

The USB-power delivery (PD) architecture is excellent for end-to-end power support, and provides quick charging possibilities through a device’s USB port. USB-PD extends beyond USB Battery Charging to allow up to 240 W charging, power support and role swap for system power optimization. The Standard Power Range (SPR) offers from 5.0 V @ 2.0 A for handhelds and wearables up to 20 V @ 5.0 A for ultrabooks. With the addition of the Extended Power Range (EPR), the Type-C connector can support up to 48 V @ 5.0 A to power for example 4K LED displays without cooling.
