As the functions of smart devices continue to increase, their power consumption begins to grow faster and faster. People are getting used to carrying portable chargers or power adapters with them. For many people, the concept of the power adapter is only at the stage of the charger, but in fact the power adapter is a transformer, which is widely used in the charger. People who are not familiar with power adapters often need to face which power adapter to use for charging.
The parameters of the power adapter are various, so it is not possible to use the adapter to charge at will. Before selecting a power adapter, first determine three adaptation conditions.
First, the interface of the adapter matches the device.
Second, the output voltage must be the same as the rated input voltage of the load (mobile equipment) or within the voltage range that the load (mobile equipment) can withstand; otherwise, the load (mobile equipment) may be burned.
Third, the output current of the power adapter should be equal to or greater than the current of the load (mobile device) to provide sufficient power.
