No, the mobile phone charger as far as possible to use the original charger or model specifications match the charger, if the 40W charger to charge can be the original 18w charger faster, but this has damage to the mobile phone battery and there are safety risks, there may be explosion accidents.
The charger (charger) can be divided into power frequency machine and high frequency machine according to the working frequency of the design circuit. The power frequency machine is designed based on the traditional analog circuit principle, the internal power devices (such as transformers, inductors, capacitors, etc.) are larger, and there is generally less noise when the load is larger, but the model has strong resistance performance in the harsh grid environmental conditions, and the reliability and stability are stronger than the high-frequency machine. (Charger) Through microcomputer control technology, the optimized Wsa Pulse charging characteristic curve is realized, and the charging current is stored
The charging voltage of the pool decreases automatically as the charging voltage rises. Combined with the pulse charging mode at the end of charging, the charging effect is more ideal. The capacity balance principle is used to determine the adequacy of the battery intelligently, to ensure that the battery is sufficient - that is, not undercharged, but also charged, charging at the same time has the dynamic tracking adjustment function of charging parameters and perfect protection function.
This understanding is wrong. From the point of view of protecting the battery life, the charging input current can not be greater than the current set by the mobile phone, so for the mobile phone with a charging current less than 40 watts, the 40 watt charging head should not charge it, otherwise it will cause the mobile phone battery life to be shortened. Generally speaking, the charging head of 40 watts can be upward compatible when charging the mobile phone, but it can not be downward compatible.
Charging head 40w charging the same brand of mobile phones fast, charging other mobile phones is relatively slow.
Each mobile phone has a charger, Huawei Apple millet and other companies produced mobile phones can only be used for their own brand, used in other mobile phone brands charging speed is very low.
Agreed. Charging an ordinary mobile phone with a fast charging power supply may feel faster, but it can't go anywhere fast, and the charging technology of the mobile phone is still determined by the chip inside the mobile phone itself.
