  Although cell phone chargers and power adapters have similar functions on the surface, they are still somewhat different in nature. Is the power adapter a charger? Let's take a look before today!

  The charger not only includes the function of the adapter, but also includes the current and voltage control functions that are compatible with battery charging. When the battery voltage is insufficient, the charger output is in a constant current state. When the battery voltage rises, the output will enter a constant voltage state. After it rises again, the charger will enter a protection state.

  The power adapter is a conversion for other electrical appliances, and is generally a constant voltage source output. The adapter usually only provides a DC power supply of about 5V and hundreds of mA, and it can be charged only when it is matched with a charging control circuit (such as a mobile phone). So there is only this essential difference between the two.

  For notebook computers, the power adapter is the charger, but not necessarily for other electrical appliances.

  Switching power supply is a method of turning 220V voltage into low voltage DC, which is different from traditional power frequency transformers. Power supplies that use this switching voltage conversion technology are called switching power supplies, and both chargers and power adapters are currently using switching power supplies.

  Charger specifically refers to something that only charges the battery, usually with a charging indicator, such as a battery car charger. He can't call an adapter. Adapter refers to something that provides power to the device.

  The difference between a charger and a power adapter: the charger includes the function of a power adapter, but there are also control circuits inside the charger that meet the charging characteristics such as constant current and constant voltage.
