something in common
From the point of view of the charging plug, the fast charging principle of fast charging and flash charging is the same.
< br >
difference
1, fast charge
< br >
By increasing the charging voltage to improve the charging power of the mobile phone, you can reduce the charging time, the vast majority of mobile phones are using this technology.
< br >
Common in the market, Xiaomi and Huawei use fast charging technology, but the charging speed will be slower, but at the same time, it is more secure, and there is no fault in mobile phone charging.
< br >
Another advantage is that when you use a regular charger, you will use the default standard charger, but it will be relatively slow. The disadvantage is that during the charging process, the phone can not run away from heat.
< br >
2. Flash charge
< br >
It is a kind of fast charge, which is to speed up the charging speed of the mobile phone through the form of low voltage and high current. It is a simple and rough charging method, which has little difference with the fast charging effect, and the peak power can reach about 20W or even higher, which can greatly shorten the charging time compared with the traditional 5V\/2A charger.
< br >
Although flash charging has a very high charging speed, it is very prone to problems. Problems such as battery damage and the inability of the charger to charge are the effects of this technology.
< br >
To sum up:
< br >
Fast charge is to charge high voltage by increasing voltage, high voltage and low current.
< br >
Flash charge is to achieve fast charging by increasing the current, high current and low voltage.
< br >
Fast charge, flash charge is best to distinguish clearly to fit the corresponding mobile phone, if the use is Xiaomi, Huawei, then do not use OPPO charger. On the contrary, use OPPO also try not to use millet, Huawei, because their charging technology is completely different. This can not only improve the efficiency of charging, but also improve the service life of the phone.
< br >
Fast charge technology is to increase the charging power of the mobile phone by increasing the voltage during charging, thereby reducing the charging time.
The flash charge is to speed up the charging speed of the mobile phone through the form of low voltage and high current, so the plug of the two chargers should not be used carelessly, and the wrong use will damage the battery to a certain extent.
The above answers hope to help a lot of friends.
the distinction is
< br \/ >
1, the charging speed is not the same, flash charging is faster.
< br \/ >
2, the voltage is not the same when charging, flash charging is low voltage fast charging, fast charging is high voltage fast charging.
< br \/ >
3, the heating degree of the mobile phone is not the same when charging, the flash charging temperature is low, and the fast charging temperature is high.
< br \/ >
4, the security of the mobile phone is not the same when charging, flash charging is safer.
1, fast charging is 5V, 4.5A, flash charging is 5V, 4A, the two are very close, this high voltage and small current way can also achieve the effect of fast charging, but compared with the low voltage and high current fast charging scheme now used, to some extent, it will lead to the heating phenomenon of the mobile phone in the charging process.
2, the use of low voltage and high current, the data cable connected to the charging connector is naturally idiosyncratic, and to withstand high current, you must have a more \"thick\" data cable, compared to the general much thicker, the interface can also be seen, low voltage fast charge has a larger and wider metal contact, to ensure the flow of large current.
3. Compared with the mobile phone, the charging interface will be adjusted in order to adapt to low-voltage fast charging, and the interface will be deeper after the transformation.
