1. QC certification
Quick Charge (QC) is a fast-charging technology developed by Qualcomm that lets you charge your device up to four times faster than conventional charging. The QC protocol specifies the voltage, current, and power requirements for quick charge technology, and it also outlines the testing procedures that manufacturers must follow to ensure that their products meet these requirements. Once the product passes the certification process, it is awarded the QC certification, and it can then be marketed as a quick charge-compatible product.
Quick Charge is not the only fast charging technology available. Other fast charging technologies include Power Delivery (PD) and Oppo's VOOC. These technologies work in a similar way to Quick Charge and are designed to provide fast charging speeds.
2. More about QC certification
- Quick Charge 1.0
QC 1.0 was the first version of Quick Charge technology launched by Qualcomm in 2013. It supported charging at 5V/2A, which is double the charging speed of traditional chargers. - Quick Charge 2.0
QC 2.0 was launched in 2014 and supported charging at 5V/2A, 9V/2A, and 12V/1.67A. - Quick Charge 3.0
QC 3.0 was launched in 2016 and supported charging at 5V/3A, 9V/2A, and 12V/1.5A - Quick Charge 4.0
QC 4.0 was launched in 2017 and supported charging at 5V/3A, 9V/2.7A, 12V/2A, and 20V/1.25A. QC 4.0 was the first Quick Charge version compatible with the USB Power Delivery (USB PD) standard. So if you had a USB PD-compatible device, you could charge it using a QC charger, but you’ll only get a maximum of 27W charging. - Quick Charge 4+
QC 4+ was launched in 2018 and supported charging at 5V/3A, 9V/3A, 12V/3A, and 20V/2.25A. - Quick Charge 5.0
QC 5.0 was launched in 2020 and supported charging at 5V/3A, 9V/3A, 11V/6A, and 20V/6A. This version supports the delivery of over 100W of power for charging devices. QC 5.0 is also compatible with the Programmable Power Supply (PPS) feature of the USB PD standard, making it faster at charging dual cell batteries.
