In most cases, a fast charge is better. Because the fast charge can charge the device in a short time, such as our common 18W QC3.0 fast charge, which can make the smartphone full of half of the electricity in about 30 minutes, it is very convenient. While most high-power flash charging products, although the charging speed is very fast, there may be problems such as too long charging time leading to too fast battery loss.
Of course, it depends on the specific situation.
If you are using an older device that only supports slow charging, then high-power flash charging may be a better choice, as this can reduce charging time and save time.
If you are using a new model that supports fast charging, fast charging is a better choice.
Therefore, we need to choose the charging method suitable for ourselves according to our own needs and the charging characteristics of the device.
Flash charge is better.

The charging speed is not the same, flash charging is faster, and the most important difference is that the safety factor of flash charging is higher than that of fast charging.

Flash charging technology belongs to low voltage and high current fast charging, other fast charging belongs to high voltage and low current fast charging, high voltage charging, mobile phone temperature is relatively high, relatively speaking, flash charging safety is very high.
