What is USB-C Power Delivery 3.0?
Power Delivery 3.0, is an even more robust standard than PD 2.0. It allows the same charging rates as PD 2.0 but does so more efficiently, and is better for battery life.
Where Power Delivery 2.0 changed the "rules" of the USB charging game, Power Delivery 3.0 focused on improving information about the charging taking place. PD 3.0 chargers and compliant devices can communicate far more effectively, letting each other know if there is a problem with the device, whether temperatures are rising too high, or if there is an unexpected drop in charging speed for some reason.
This is really important for diagnostics, as well as the dynamic management of charging. Power Delivery 3.0 allows for much finer control of VBUS power (an important component of USB power management). This is important because it allows the charger and device to negotiate the optimal charging rate while increasing battery longevity.
Take a look at the specs of a charger before you make a purchase to determine whether it supports Power Delivery. If it does, you know that you’re getting the latest in safe & fast charging abilities. In 2018 the USB governing body, the USB Implementers Forum, instigated a new naming convention where chargers that could support PD 3.0 over USB-C could be designated as Certified USB Fast Chargers so you can also keep your eye out for that certification.
