There is little difference between flash charging and fast charging, and the main differences are as follows:
First, charging speed: flash charging is faster than fast charging.
Second, charging voltage: flash charging is low voltage fast charging, fast charging is high voltage fast charging.
Third, the degree of heating: flash charging temperature is low, fast charging temperature is high.
Four, safety performance: flash charging is safer than fast charging.
Flash charge is actually the fast charging standard VOOC developed by OPPP, and many new models of OPPP are currently using SuperVOOC flash charge technology. However, although the flash charge improves the charging speed, but OPPP flash charger and other brands of chargers are not compatible, so you need to be equipped with a special charger when charging the mobile phone, otherwise it will cause harm to the mobile phone battery, serious harm to the mobile phone itself.
Fast charging is actually a QC standard developed by Qualcomm. Unlike flash charging, fast charging uses the technology of increasing voltage and reducing current fast charging. The current third generation QC fast charging technology, there are many improvements on the basis of the previous generation, of course, now there is the latest QC4.0 technology, but there are few products using this charging technology.
It is understood that the latest QC4.0 technology charging speed on the basis of the original speed increased by 20%, in addition to improve the charging speed at the same time also pay attention to protect the charging battery, wire and connector charging equipment, but from the data alone, fast charging relative to flash charging and there is no obvious advantage.
