Qualcomm Quick Charge, referred to as QC fast charging, is a set of fast charging standards for smart terminal devices launched by Qualcomm in the United States. This fast charging technology has been upgraded from QC2.0 and QC3.0 to the latest QC4 and QC5. Among them, QC5 supports charging power up to 100W. The release of Qualcomm's latest charging protocol not only provides 100W fast charging power, but also hopes to solve the current compatibility problem between high-power fast charging and devices.
Qualcomm updated the Quick Charge certified device list in May 2021. Charging head network has sorted out the charger protocol chips that support Qualcomm QC5 and QC4+ based on the updated model. Among them, there are 4 protocol chips that have passed Qualcomm QC5 certification, and 22 protocol chips that have passed Qualcomm QC4+ certification.
Currently, the QC5 protocol chip recommended by Qualcomm's official "Quick Charge devices list" technical document has a total of four brands, each with a protocol chip. At the same time, these fast charging protocols also support USB PD and PPS protocols and have been widely used in the market.
At the same time, Qualcomm also updated its phones that support QC5 charging technology, for the Nubia Red Devil 6 and Nubia Red Devil 6 Pro.
Red Magic 6Pro supports maximum 120W fast charging, and is equipped with a 120W gallium nitride charger and 6A data cable standard. The machine uses dual-cell plus dual-charge pump technology, which can fill the 4500mAh battery in 21 minutes.
In terms of surrounding ecology, Besi has launched three major categories of products: Qualcomm QC5 licensed and certified charger, power bank and car charger. Among them, the charger has been launched, and the power bank and car charging will be released in the near future.
