The difference between power adapter and charger, can they be used together?

With the development of society and the popularization of technology, more and more people use electronic products. For example: mobile phone power cords, data cables, chargers, charging sockets, laptop charging cables, USB, etc. These may be adapters. Think about how we charge mobile phones every day, how to charge laptops? Today is mainly to tell you the difference between a power adapter and a charger, what is the adapter, what is the role of the power adapter, let’s learn together! The difference, can you mix the two? Charger: The English name of the charger is Charger, which is usually a device that converts alternating current into low-voltage direct current. The charger is a DC power supply dedicated to rechargeable batteries. It contains control circuits such as current limit and voltage limit to meet the charging characteristics. Chargers are widely used in various fields, especially in the field of life, and are widely used in common electrical appliances such as electric cars and flashlights. It usually charges the battery directly without passing through any intermediate devices. The difference between the power adapter and the charger is that the process of the charger is: constant current-constant voltage-trickle, three-level smart charging. Adopting the three-level charging theory can greatly improve the charging efficiency, shorten the charging time, and extend the battery life. The three-level charging adopts constant current charging, constant voltage charging, and floating charging for maintenance charging. Generally, it can be divided into three stages: fast charging, supplementary charging and trickle charging: fast charging stage: charging the battery with a large current can quickly restore the battery power, the charging rate can reach 1C or more, the charging voltage is low, but the charging current will be Be limited to a certain range. The difference between the power adapter and the charger constitutes the charging phase: Compared with the fast charging phase, the supplementary charging phase can also be called the slow charging phase. At the end of the fast charging phase, the battery is not completely sufficient, and a supplementary charging process needs to be added. The supplementary charging rate generally does not exceed 0.3c. As the battery voltage increases after the fast charging phase, the supplementary charging voltage should also increase and stay within a certain range. Trickle charging stage: In the later stage of the charging stage, when it is detected that the temperature rise exceeds the limit value or the charging current decreases to a certain value, it starts to charge with a smaller current until certain conditions are met. A common power adapter in the market is a power converter that passes through a converter, a rectifier, and a regulator, and the output is direct current, which can be understood as a low-voltage regulator when it encounters a power source. The difference between the power adapter and the charger is that the power adapter is widely used in routers, telephone consoles, game consoles, language transponders, walkmans, laptops, mobile phones and other devices. Most power adapters can automatically detect 100 ~ 240V ac (50/60Hz). The power adapter is a small portable electronic device and electronic and electrical power conversion equipment. It connects the power supply with a line to the host, which can reduce the size and weight of the host. Only a few are built in the host device to integrate the power supply part, mainly considering Many factors such as volume, cost, or certification. The difference between power adapter and charger, its internal power transformer and rectifier circuit, according to its output type can be divided into AC output type and DC output type; according to the connection method can be divided into wall type and desktop. Each power adapter has a nameplate indicating the power supply, input/output voltage and current, and pay special attention to the input voltage range. What does the power adapter do? What is the function of the power adapter? Generally speaking, the function of the power adapter is a transformer and a rectifier. The AC at home is 220V, and the computer is 12V DC, so we can be sure that the power adapter is a transformer and a rectifier. The adapter is a transformer, so we should know that AC 220V is used for voltage conversion through a transformer, and DC is used for voltage conversion through rectification. There is consumption, and these consumption will be converted into heat, so it is normal for the power adapter to generate heat. The transformer is made of silicon steel sheet. After the transformer is energized, magnetic flux is generated. Magnetic flux will generate force between the silicon steel sheets and produce a buzzing sound, which is normal. But too loud sound is not normal, there are many reasons: 1. The AC voltage is unstable. 2. The chip is damaged. 3. Short circuit between turns. 4. Damaged components, etc. By the way, the purpose of the adapter is to convert AC power to DC power. The general adapter requires a lot of space and size. Smaller machines will choose an external power adapter. In order to save the design volume and space of the product, it is easy to replace, and the adapter is used. It is practical. Generally speaking, the higher the voltage, the more dangerous it is to put it inside the machine. Therefore, the separation of the power adapter and the device is mainly to isolate the area of u200bu200bhigh and low voltage conversion, and the device is relatively safer. The cost is also lower. Summary: Due to different functions. The power adapter and charger cannot be mixed, especially when the power adapter is connected to the battery, the adapter cannot complete the charging operation of the battery. If the battery has no protection device, it may directly cause damage to the battery. So before use, please make sure whether it matches.
