With the widespread application of mobile devices, wired charging can no longer meet the needs of users, and fast charging protocols have emerged as the times require. Fast charging protocol is an intelligent charging technology for mobile devices, which can improve charging speed and security, and provide users with better charging services. Currently, there are several common fast charging protocols on the market:
1. Qualcomm Quick Charge
Qualcomm Fast Charging Technology is one of the most widely used fast charging protocols on the market, which can provide higher charging power than traditional chargers, and can charge mobile devices by at least 50% in a short time. Qualcomm Fast Charging uses voltage adjustment to achieve fast charging, allowing for dynamic negotiation between the charger and the mobile device, and dynamically adapting the voltage based on the status and needs of the mobile device. Currently, four versions have been released, and the latest version can support charging power of up to 100W.
2. MediaTek Pump Express
MTK charging technology is an efficient, safe, and fast charging method that allows for dynamic negotiation of electrical parameters between the charger and the device, thereby achieving fast charging and minimizing overheating and charger damage. Pump Express 3.0 allows supported devices to receive 5 hours of charging in 5 minutes, with a maximum supported charging power of 18W. It can also achieve higher power charging through intelligent step-down.
3. USB Power Delivery (USB-C PD)
USB-C PD is a charging technology that can provide high power to devices through a USB interface. It uses a two-way communication protocol and can output up to 100W of power through the USB interface. USB-C PDs can provide different voltages and currents for different devices to achieve fast charging, with a maximum supported charging power of up to 100W.
4. Oppo VOOC Flash Charge
Oppo VOOC flash charging is a charging technology launched by Oppo Corporation, which supports charging power up to 65W. It uses low-voltage fast charging technology. By using a special VOOC charging line and charger, it can quickly charge and maintain low temperature, and the charging time is four times faster than that of a normal charger.
Summary
There are many fast charging protocols on the market, each with its advantages and disadvantages. Different mobile phone manufacturers also have their own fast charging technologies, such as Huawei's super fast charging, Xiaomi's fast charging, Apple's fast charging, and so on. Choosing a fast charging protocol also requires making choices based on specific needs and device types to achieve the best charging effect.
