USB-Type-C AC/DC Wall Charger

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 100 W charging, power support and role swap for system power optimization. The connector offers from 5.0 V @ 2.0 A for handhelds and wearables up to 20 V @ 5.0 A for ultrabooks
