The charging principle is different: the voltage controlled by the fast charging technology is lower, and the output specification is 4.5V\/5A. Flash charging technology strictly regulates the current, and the output specification is 5V\/4A.

2. Charging speed is different: Fast charging technology can charge half of the phone's electricity in 5 minutes. Flash charge technology can charge 5 minutes for 2 hours of talk, power conversion rate of 95%, charging 30 minutes can charge the phone's power from 0% to 70%.

3. The impact on the mobile phone battery is different: fast charging technology will not cause long-term life and maximum capacity loss of the battery. Flash charging technology will reduce the line loss a lot, and effectively curb the phenomenon of mobile phone fever. I think flash charge is good, because it is fast enough.
