The power of mobile phone chargers is generally between 5W and 15W. Among them, 5W refers to the output power of the standard USB 2.0 charger, while 15W refers to the output power of the fast charging charger.
The USB 2.0 charger is the standard charger equipped with most mobile phones, with an output power of generally 5V/1A, which is 5W. This type of charger is suitable for ordinary mobile phone charging, with a slower charging speed, but relatively cheap and relatively safe.
The fast charging charger is a product that has only become popular in recent years, with an output power of usually 9V/2A or 12V/1.5A, which is 15W. Fast charging chargers can achieve higher charging power and faster charging speed, which can greatly shorten charging time. However, the price is relatively high and may have a certain thermal impact on the phone.
It should be noted that the power of different mobile phone chargers is not exactly the same, and different phones also have their own charging specifications. If you are unsure how to choose a charger, it is best to use the original charger provided with your phone to avoid issues such as discomfort and ensure safe use.
