In daily life, the use of chargers is essential, so how much do you know about the needs of the Charger? Power adapter and Charger what is the difference between the two? Power adapter PK charger, want to understand the difference between the two, take a look at the following shared it!

　　The Charger usually refers to a device that converts AC power into low-voltage DC power, which includes internal control circuitry to limit the current and voltage to meet the charging characteristics, and the power adapter is a power converter that goes through voltage transformation, rectification, and voltage regulation, and the output is DC, which can be understood as a low-voltage regulated power supply in the case of meeting the power. Here we will talk about what is a power adapter? What is a charger? What is the relationship between the two and the difference between them?

　　Charger: The English name Charger usually refers to a device that converts AC power into low-voltage DC power. The Charger is a special DC power supply for rechargeable batteries, which includes internal control circuits to limit the current, voltage, and other charging characteristics to meet.

　　The Charger is widely used in various fields, especially in the field of life is widely used in electric vehicles, flashlights, and other common appliances. It generally charges the battery directly, without any intermediary devices or equipment.

　　The process of the Charger is: constant current - constant voltage - trickle current, three-stage intelligent charging. The three-stage charging theory in the charging process can greatly improve the charging efficiency of the battery, shorten the charging time, and effectively extend the battery life. The three-stage charging adopts constant current charging, then constant voltage charging, and finally, float charging for maintenance charging.

　　It is generally divided into three stages: fast charging, top-up charging, and trickle charging:

　　Fast charging stage: Charging the battery with a high current to quickly restore the battery power, the charging rate can reach more than 1C. The charging voltage is lower but will limit the charging current within a certain range of values.

　　Complimentary charging stage: Compared with the fast charging stage, the complementary charging stage can also be called the slow charging stage. When the fast charging stage is terminated, the battery is not fully charged, so it needs to join the complimentary charging process. The complementary charging rate generally does not exceed 0.3C, because the battery voltage increases after the fast charging stage, so the charging voltage in the complementary charging stage should also increase and be constant within a certain range.

　　Trickle charge stage: In the late stage of the complementary charging stage, when the temperature rise is detected beyond the limit or after the charging current is reduced to a certain value, it starts charging with a smaller current until it meets certain conditions and then ends charging.

　　Power adapter: the English name Adapter, the common power adapter on the market is after the conversion, rectification, and voltage regulator power converter, the output is DC, in the case of meeting the power can be understood as a low-voltage regulated power supply.

　　Power adapters are widely used in routers, telephone sub-computers, game consoles, language repeaters, Walkman, notebooks, cell phones, and other devices. Most power adapters can automatically detect 100 to 240V AC power (50/60Hz).
