Flash charging and fast charging of mobile phone charger are fast charging, but the way is different
Views : Update time : 2021-08-20
Nowadays, the demand of users when buying mobile phones is also higher and higher. In addition to high appearance and good-looking photos, the charging efficiency is also faster. As a result, flash charging and fast charging have now become trademarks and selling points of major mobile phone manufacturers. At first glance, it is only a word difference, and the literal meaning is the same, but they are not the same. Let's follow the charger manufacturer weisp Xiaobian to understand:In fact, from the principle of charging, they are basically the same, but in different ways. In terms of fast charging, which is widely used now, it is to increase the voltage to achieve high-voltage fast charging. In this way, the charging time can be greatly shortened.
Flash charging adopts low voltage and high current opposite to fast charging to achieve the purpose of fast charging. Although both can be charged quickly, but in different ways, the plug and data cable of the two chargers can not be used indiscriminately.
In fact, as an important bridge for charging transmission, data line is quite sensitive to changes in voltage and current. The earliest data line is only 9V / 2A at most, which can only withstand 3a in theory. Therefore, attention should be paid to those particularly thin data lines, which are easy to heat and unstable security. Compared with the type-C data line popular in recent two years, it can withstand a maximum voltage and current of 20V / 5A, and its safety performance is much higher.
However, when using the mobile phone charger everyday, friends will find that the poor data cable can not activate the fast charging of the mobile phone, and even sometimes the high-quality data cable is the same. Just because the micro USB cable can only provide 2A current, it is normal to fail to activate fast charging.
Poor quality data cable will not only cause slow charging, but also cause hot mobile phones and chargers, and the safety hazard is also great. However, the advantages and disadvantages of the data line can not be distinguished by the naked eye. Many charger manufacturers on the market do a beautiful job on the outside of the data line, but the internal structure will use inferior materials to save costs. Therefore, when buying chargers and data, try to buy them from regular shops and official websites. Another point is that the mobile phone will generate heat when charging, which does not mean that the mobile phone is hot when charging.
