What is the comparison between a charger and an adapter?(图1)

　　1. What is a charger?

　　Generally speaking, a charger is a device that converts alternating current into low-voltage direct current. It is a DC power supply dedicated to rechargeable batteries. Its internal includes current limiting, voltage limiting control circuit and other satisfactory charging characteristics. Depending on the condition of the battery, it may be necessary to limit the current and voltage, all of which are to charge the battery.

　　Chargers are widely used in various fields, especially in electric vehicles, flashlights and other common electrical appliances. It usually does not require any intermediate equipment to directly charge the battery.

　　2, what is a power adapter?

　　power adapter is a small portable electronic device and power replacement device. It places the power supply device outside and connects to the host through a line, which can reduce the size and components of the host. Only a few devices and electrical appliances embed the power supply into the host.

　　Power adapter is a power converter that undergoes voltage conversion, rectification and stabilization. The output is direct current, which can be understood as a low-voltage stabilized power supply under the condition of meeting the power requirements. It is widely used in routers, telephone slaves, game consoles, notebook computers, mobile phones and other equipment. Most power adapters can automatically detect 100-240V AC (5060hz). What is the difference between a charger and an adapter?

　　3. What is the difference between a power adapter and a charger?

　　The power adapter directly supplies power to users who need a stable voltage, so it is a regulated power supply. The power adapter can be used as a charger, because the internal resistance of the power adapter and the battery is very large, with the characteristics of "soft" and "mutual habit".

　　The chargers of mobile phones and computers do not include the charging control circuit, which is usually completed on the host. Therefore, mobile phone chargers and laptop chargers are only power adapters, which do not include charging control circuits. Natural cell phone chargers, laptop chargers and other similar power sources controlled by the host are actually power adapters. The traditional title is misleading because we are used to referring to the power supplies of appliances and equipment as chargers
