The power adapter refers to the power supply that provides power to the device, such as the computer host power supply, printer power supply, monitor power supply, these are not called chargers. The power adapter has the characteristics of small size, energy saving and environmental protection, multiple safety protection, long service life, and wide application range. It can be roughly divided into desktop power adapter, in-line power adapter, multi-channel power adapter, USB power adapter, etc. Most mobile PC power adapters can automatically detect 100 ~ 240V AC (50/60Hz). Basically, all mobile PCs have an external power supply, which is connected to the host with a line, which can reduce the size and weight of the host. Only a very few models have a built-in power supply in the host. There is a nameplate on the power adapter, which indicates indicators such as power, input and output voltage and current. Pay special attention to the range of input voltage, which 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 the power supply that only charges the battery. It is based on the switching power supply plus a charging detection and control loop, such as constant current, reverse connection, floating charge, automatic adjustment of the equalizing voltage and so on. The common ones are USB chargers, as well as mobile phone chargers, notebook power supplies, battery car chargers, etc. The chargers generally convert 220V into a suitable DC voltage. The function of charging the rechargeable battery.
So the power adapter cannot be used as a charger. To avoid damage to the battery. If you use the power adapter as a charger to charge the battery, it will either not be fully charged, or the battery will be damaged by overcharging.
