See the brand Huawei's new mobile phone's original charging plug is to support fast charging, so if your charger is original, do not doubt that it absolutely supports fast charging.
If the logo is not original, then we can also confirm by looking at the logo on the charger, if the charger has the words \"SuperCharge\
The second is the data cable, if the data cable USB port, fast charging port, is purple, then it also indicates that the data cable is to support fast charging.
Again, if there is a \"lightning\" mark on the data line, it also means that the data line supports fast charging, and of course, without this mark, it does not mean that the data line does not support fast charging.
Why can't you charge it fast? It is clear that the charger and data cable support fast charging, but can not achieve fast charging when in use? The reason can be that the interface at both ends of the data cable is in poor contact, or the interface is dirty, you can clean the interface and plug it tightly.
In addition, after the phone power exceeds a certain value, in order to protect the power, the system will automatically disable the super fast charge function.
For example, if you buy a nickel-metal hydride charger, which is marked with an output current of 1.5A, this is fast charging, because the current 5 nickel-metal hydride battery capacity is more than 2500mAh (2.5Ah), with 1.5A current charging, about two hours will be full; If the charger is marked with output current of 100mA or 200mA, it is slow charging, and it will take about 20 or 30 hours to charge the 2500mAh battery, and it may not turn the lamp after full (the current is too small to detect).
