Double flash charge means mainly for some mobile phones, in order to increase the speed of fast charging, therefore, the two batteries are added to the mobile phone, so that in the process of charging, the charger is respectively charged for the two batteries, so that its charging speed will certainly be faster than the charging speed of a battery, but this has a disadvantage, that is, if two batteries are used, Your total amount will be smaller than that of a battery
Is a mobile phone fast charging technology, is developed by vivo fast charging technology, the use of dual charging chip parallel charging, than the ordinary charging technology speed up 2 times, and has nine safety protection technology.
