What is QC? And PD?

Both USB Power Delivery (PD) and Qualcomm Quick Charge (QC) are crucial fast charging systems that have significantly improved the user experience by drastically reducing device charging times. PD offers a more universal and powerful solution, capable of charging a wider range of devices, including laptops, thanks to its higher wattage capabilities and dynamic voltage negotiation.

QC, primarily found in Snapdragon-powered devices, also provides rapid charging through intelligent voltage adjustments. The importance of these systems lies in their ability to quickly replenish device batteries, minimizing downtime and enhancing productivity and convenience in a world increasingly reliant on portable electronics. 

While QC has been a long-standing fast charging option, PD's growing adoption and versatility, particularly with the rise of USB-C, position it as a more encompassing and future-proof charging standard. Ultimately, both PD and QC address the fundamental need for faster and more efficient power delivery, albeit with different technological approaches and levels of universality.
