In our lives, there are many electronic products. The least use of these electronic products is the charger and the power adapter, but many people are not very familiar with the difference between the two, so let’s follow the charger below. Let the manufacturers understand the difference between the charger and the adapter:
1. What is a charger?
A, what is the charger?
A charger usually refers to a device that converts AC power to low-voltage DC power. It is a dedicated DC power supply for rechargeable batteries. It includes current limiting, voltage limiting and other control circuits that meet the charging characteristics. Depending on the condition of the battery, current may be limited, or voltage may be limited, and everything serves to charge the battery.
Chargers are widely used in various fields, especially in the field of life are widely used in electric vehicles, flashlights and other common electrical appliances. It generally charges the battery directly without passing through any intermediary equipment and devices.
2. What is an adapter?
Second, what is the adapter?
The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It puts the power supply externally and connects it to the host with a line, which can reduce the size and weight of the host. Only a few devices and electrical appliances have the power supply built in the host. Inside.
The power adapter is a power converter that undergoes transformation, rectification and stabilization, and the output is direct current, which can be understood as a low-voltage stabilized power supply when the power is satisfied. It is widely used in routers, mobile phones, game consoles, language repeaters, walkmans, notebooks, mobile phones and other equipment. Most power adapters can automatically detect 100～240V alternating current (50/60Hz).
3. What is the difference between a charger and an adapter?
There is a difference between a power adapter and a charger. The power adapter directly supplies power to electrical appliances and requires 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 large, and the characteristics are "soft" and "adapt to each other", so there is no problem.
The chargers of mobile phones and computers do not include the charging control circuit. The charging control circuit is generally completed on the host. Therefore, mobile phone chargers and laptop chargers are actually just power adapters. They do not include charging control circuits. Naturally, mobile phone chargers and laptop chargers, such as the power source controlled by the host, are actually power adapters, just traditional The name is misleading, because people are used to calling the power supply for electrical appliances and equipment a charger.
The difference between the charger and the adapter is actually summarized as follows: the charger includes the function of the power adapter, but there are also control circuits inside the charger that meet the charging characteristics such as constant current and constant voltage. After understanding the above content, I believe everyone has a clear understanding of the difference between chargers and adapters.
