The difference is to raise the voltage and lower the current.
Usually referred to as fast charge, the principle is to increase the charging voltage. The phone will show that it is fast charging, and the main function is the charging head.
Advantages: Because the current is low, the compatibility is strong, and the data line is not too high, so the cost is low.
Disadvantages: Increasing the voltage will generate higher heat, causing the phone to heat up and affecting battery life.
Note: Fast charging does not have high requirements for mobile phone chargers and data cables, and chargers that support flash charging technology can be used, which will not cause substantial harm to mobile phone batteries.
Flash charge reduces voltage and increases current
Many brands say flash charge, the principle is to increase the charging current. In the case of constant voltage, the higher the current, the less time the battery will be fully charged.
Advantages: When charging with flash charge, heat will be transferred to the charging head, so it is safer.
Disadvantages: Due to the large current, special charging head and data cable are required, so the cost is higher and the price is higher.
Note: Flash charging technology requires a customized charger and is incompatible with other chargers. If you use an incompatible charger, it will not only cause harm to the battery, but also greatly reduce the charging efficiency.
There are five differences between fast charging and flash charging: different voltages, different principles, different charging speeds, different degrees of heat, and different safety.
The first difference: fast charge is high voltage fast charge, and flash charge is low voltage fast charge.
The second difference: fast charging is to increase the power of charging, in the case of a certain battery capacity, increasing the power can reduce the charging time, the greater the power, the shorter the charging time.
The third difference: flash charging is faster than fast charging.
The fourth difference: the fast charging temperature is higher, and the flash charging temperature is lower.
Hello, fast charge and flash charge are both fast charging technologies, but there are still some differences between them. First of all, fast charge technology mainly refers to the technology of fast charging by increasing voltage and current, which can fill the battery in a very short time. The flash charging technology is the unique fast charging technology of OPPO mobile phones, which is based on the upgraded version of VOOC technology. Its main feature is that it can be fast charged when the screen is on, and it is more secure, so its charging speed is faster than traditional fast charging technology.
In addition, the flash charge also supports an independent charging chip, which is responsible for monitoring and controlling the current, and can constantly adjust the current of the charger, thus maximizing the protection of the health of the battery.
