Qualcomm® Quick Charge™ and USB Power Delivery both offer better charging performance and faster charging. Your device needs to support Qualcomm® Quick Charge™ or USB Power Delivery.
Qualcomm Quick Chargers, or QC 3.0, have a component inside that speaks to the Snapdragon processor in your phone or tablet. The communication between the two chips negotiates voltage based on how full the battery is. It’s also proprietary to the Qualcomm company. So your phone needs the right processor, and your charger needs the right chip in order to charge as fast as possible.
USB Power Delivery, or PD 3.0, is used specifically by USB Type-C™ ports. It’s royalty-free for manufacturers because it was developed by a non-profit organization, USB Implementers Forum. As an official part of USB technology and can be supported by any manufacturer who incorporates the specifications. PD requires a CC (communications channel) pin in the Type-C cable to negotiate the voltage, current, and direction of the power flow between two ports. The eventual aim of USB PD and Type-C is to create one standard port on all devices (phones, tablets, and laptops) for safe, fast-charging input and output power and high-speed data.
