Before introducing the difference between today's charger and power adapter, we must first understand what a charger is and what is a power adapter.

The power adapter refers to the power supply for the device, such as the power supply of the computer host, printer power supply and display power supply. These are not called chargers. The power adapter has the characteristics of small size, energy saving, environmental protection, multiple safety protection, long replacement time and wide application range. It can be roughly divided into desktop power adapter, embedded power adapter, multi-channel power adapter, USB power adapter and so on. A large number of mobile PC power adapters can automatically detect 100~240V AC (50/60Hz). The power supply of all mobile PCs is connected to the host from the outside through a cable, which can reduce the size and weight of the host. Only a small amount of power is built into the main unit. There is a nameplate on the power adapter, which is marked with power, input and output voltage, current and other indicators. Please pay special attention to the input voltage range. This is the so-called "travel power adapter". The power adapter includes the charger, but the charger does not include the power adapter.

 

The charger refers to a power source that only charges the battery. It adds a charging detection and control loop based on the switching power supply, such as constant current, reverse connection, floating charging, automatic adjustment of equalization voltage, etc. Commonly used are USB chargers, mobile phone chargers, laptop power supplies, battery car chargers, etc. These chargers usually convert 220V into a convenient DC voltage. Depending on the type of rechargeable battery, a charge management circuit will be added that has a rechargeable battery for charging.

If you replace the power adapter with a charger to charge the battery, the result is that the charging is not fully charged, and overcharging will damage the battery.
