As the functions of smart devices continue to increase, their power consumption begins to become faster and faster. People have become accustomed to carrying portable chargers or power adapters with them. For many people, the concept of power adapter only stays at the stage of charger, but in fact, power adapter is a kind of transformer, which is widely used in chargers.
People who are unfamiliar with power adapters often have to face which power adapter is used for charging. The parameters of the power adapter are varied, so it is not possible to use the adapter for charging at will. Before choosing a power adapter, you must first determine three adaptation conditions.
1. The interface of the adapter matches the device.
2. 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.
3. 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.
