Dual engine fast charging head and flash charging are both fast charging technologies, but their implementation methods and principles are slightly different.
Dual engine fast charger is a fast charging technology used by vivo mobile phones, which uses a dual charging chip and a dual charging circuit, which can provide two power inputs at the same time, so as to achieve faster charging speed. The dual-engine fast charger also uses a technology that intelligently manages the charging current, which can be dynamically adjusted according to factors such as the phone's battery and temperature, thus ensuring charging speed and safety.
Flash charge is a fast charging technology used by Huawei mobile phones. It uses high-voltage and high-current charging to fully charge mobile phones in a short time. Flash charging also uses the technology of intelligent management of charging current, which can be dynamically adjusted according to factors such as phone power and temperature, so as to ensure charging speed and safety.
In general, the dual engine fast charging head and flash charging are a kind of fast charging technology, they both use intelligent management of charging current technology, can be dynamically adjusted according to the phone power and temperature and other factors, so as to ensure charging speed and safety. However, the dual engine fast charge head uses a dual charging chip and a dual charging circuit, which can provide two power inputs at the same time, so as to achieve faster charging speed, while the flash charge uses a high-voltage and high-current charging method, which can be fully charged for the mobile phone in a short time.
Dual engine fast charging head and flash charging are two kinds of fast charging technology.

Dual engine fast charger refers to a technology that uses two chargers to charge at the same time, which can divide the current into two ways by charging at the same time, and quickly replenish the battery's power. The use of dual engine fast charging head can charge faster, generally within 30 minutes to 50% to 70% of the charge.

Flash charge refers to the use of more powerful charging technology, high current is injected into the battery, so that the battery is quickly charged. The advantage of flash charging technology is that it is fast, and it can generally charge the power to 50%-70% within 30 minutes. However, the heat during charging is more serious, which also has a certain impact on the life of the battery, and it is necessary to pay attention to the charging time and frequency.

Although both technologies can achieve fast charging, the dual engine fast charging head pays more attention to charging safety and stability, and can charge multiple devices at the same time, while the flash charging power is higher and can be charged in a shorter time, but it should be noted that multiple fast charging may have an impact on battery life.
