THE BENEFITS OF USB POWER DELIVERY
This allows the charger to provide the exact amount of power required to charge it in the shortest possible time.
With 27-watt power available, this means faster charging times for almost all PD-enabled smartphones and tablets.
It also offers additional flexibility for charging larger devices such as thinkpads and MacBooks with the same charger.
The consequence is less time to spend and more time to get on with your day.
