one
The output voltage is higher than the ordinary charger,
two
The charging current output is larger than that of the ordinary charger
General charge refers to the 5v2A or 5v1A, the former is the Android standard, the latter is exclusive to the iPhone (although your battery life is short, but you charge slowly ah). Most of the data cables and charging heads on the market meet the standard of universal charging, after all, they are basically public models.
2, ordinary fast charge
There are more ordinary fast charges on this side, such as Huawei's FCP fast charge, which is 9V2A, which you can also understand as high voltage and low current. There have been QC2.0 fast charge \/QC3.0 fast charge, these are essentially ordinary fast charge (although QC3.0 is a lot faster), yes, there are PD fast charge, to this stage, has begun to play how much W, with the current and voltmeter a bit into the cliche.
The advantage of high voltage and low current fast charge is that it is cheap, and basic ordinary data lines can be used, but the heat will be more serious.
3. Flash charge
The concept of flash charge was first proposed by OPPO, five minutes of charge, 2 hours of talk. At first, it is called VOOC flash charge, which is different from ordinary fast charge, and this is a low voltage and high current fast charge.
Oneplus's DASH flash charge is similar to OPPO's flash charge, and in the early years, OnePlus had a phone that charged at 5v4.5A, with 5V2A as the standard, the current is increased.
The high voltage and low current flash charge cost is relatively high, the ordinary data cable can not meet its fast charge needs, so from the mobile phone to the charging head to the data cable, and other mobile phones are different, can be understood as a strengthened version of the mobile phone, can afford higher temperatures, heat dissipation and other performance must be better, after all, charging will heat, heat must be solved. The line of heating short circuit is not a good line, the material from inside to outside, is a strengthened version of the ordinary line, otherwise don't use it.
The difference is that the flash charging system has an innovative double charging chip and double charging circuit, two sets of circuits at the same time power supply, intelligent management of charging current, bringing twice the charging speed of ordinary mobile phones, charging faster and more stable. The ordinary charger has only a single charging road, and the charging speed is completely incomparable with flash charging.
Charging a mobile phone that supports flash charging is fast and stable, and charging a mobile phone that does not support flash charging is basically the same as charging an ordinary charger.
